How many pounds of candy that sells for $1.25 per Ib must be mixed with candy that sells for $0.75 per lb to obtain 20 lb of a mixture that should sell for $1.20 per lb?
Let x be the number of pounds of candy that sells for $1.25 per lb that we need to mix, and let y be the number of pounds of candy that sells for $0.75 per lb. We can set up a system of equations to represent the problem:
x + y = 20 (we need a total of 20 pounds of candy in the mixture)
1.25x + 0.75y = 1.20(20) (the value of the mixture should be $1.20 per lb)
Simplifying the second equation, we get:
1.25x + 0.75y = 24
Multiplying the first equation by 0.75 and subtracting it from the second equation, we can eliminate y:
1.25x + 0.75y = 24
0.75x + 0.75y = 15
0.5x = 9
Dividing both sides by 0.5, we get:
x = 18
Therefore, we need 18 pounds of candy that sells for $1.25 per lb and 2 pounds of candy that sells for $0.75 per lb to make a 20-pound mixture that sells for $1.20 per lb.
2/7+(-3/4) + (-2/7)+4/3 please show all work! Thank you so much!
To add these fractions, we need to find a common denominator. The least common multiple of 7, 4, and 3 is 84, so we will use 84 as the common denominator.
2/7 + (-3/4) + (-2/7) + 4/3
= (2/7) * (12/12) + (-3/4) * (21/21) + (-2/7) * (12/12) + (4/3) * (28/28) (multiplying each fraction by an equivalent form to get a common denominator of 84)
= 24/84 - 63/84 - 24/84 + 112/84 (simplifying each fraction)
= -51/84 + 112/84 (combining like terms)
= 61/84 (simplifying the resulting fraction)
Therefore, 2/7 + (-3/4) + (-2/7) + 4/3 = 61/84.
Answer:
7/12
Step-by-step explanation:
2/7 + (-3/4) + (-2/7) + 4/3
2/7 - 3/4 - 2/7 + 4/3 (+ * - = -)
2/7 - 2/7 - 3/4 + 4/3 (Distribution Property)
0 - 3/4 + 4/3
- 3/4 + 4/3
4/3 - 3/4 (Distribution Property)
LCM = 3 * 4
= 12
(16 - 9) / 12
7/12
So, the final answer is 7/12.
Hope my answer helps you ✌️

Elena has a budget of $50 for a new watch. she finds two watches that are $8 above and $8 below her budget, respectively.
Part A
write an absolute value equation that can be used to find the prices of the wayches elena finds
0=|x+___|+___
Part B
What are the prices of the watchee Elena finds?
$______and$______
The requreid, The absolute value equation to represent this situation is 0 = |x - 50| + 8 and Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Part A:
Let x be the price of the first watch she finds. Then the price of the second watch is x - 16 (since it is $8 below her budget).
The absolute value equation to represent this situation is:
0 = |x - 50| + 8
Part B:
To solve the absolute value equation, we need to consider two cases:
Case 1: x - 50 is positive
If x - 50 is positive, then we can write the equation as:
0 = x - 50
x = 50
This means that the watch Elena finds costs $50, which is exactly her budget.
Case 2: x - 50 is negative
If x - 50 is negative, then we can write the equation as:
0 = -(x - 50)
0 = -x + 50
x = 50
Again, this means that the watch Elena finds costs $50.
So, Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.

What is 2x+21? Please it's due in about 15 minutes!!!
Answer:
The value of x is 21
Step-by-step explanation:
2x+21 is a linear equation with one unknown, x. To solve for x, we can use the following steps:
1. Subtract 21 from both sides of the equation. This will isolate x on the left-hand side of the equation.
```
2x+21 - 21 = x
```
2. Divide both sides of the equation by 2. This will divide both sides of the equation by 2, which will cancel out the 2 on the left-hand side of the equation, leaving x by itself.
```
x = (2x+21)/2
```
3. Simplify the right-hand side of the equation.
```
x = x/2 + 21/2
```
4. Combine like terms on the right-hand side of the equation.
```
x = (1/2)x + 21/2
```
5. Subtract (1/2)x from both sides of the equation. This will isolate x on the left-hand side of the equation.
```
x - (1/2)x = (1/2)x + 21/2 - (1/2)x
```
6. Simplify the right-hand side of the equation.
```
(1/2)x = 21/2
```
7. Multiply both sides of the equation by 2. This will multiply both sides of the equation by 2, which will cancel out the (1/2) on the left-hand side of the equation, leaving x by itself.
```
2*(1/2)x = 21/2 * 2
```
8. Simplify the right-hand side of the equation.
```
x = 21
```
Therefore, the value of x is 21.

Which of the following graphs matches the relationship shown in the table?
A. Y
B. Z
C. W
D. X
Answer: Y
Step-by-step explanation:
Remember: 1 yard = 3 feet. Consider this for all the choices!!
W starts at (0, 1) making it automatically incorrect as 0 yards cannot equal a foot, it equals zero feet.
X has a point marked (1, 0) making it automatically incorrect as 1 yard does not equal to 0 feet.
Z starts with the point (0, 3) making it automatically incorrect as 0 yards cannot equal 3 feet,
Y does not have any incorrect points, and properly illustrates that 1 yard is equal to 3 feet with the points provided, Y is correct

Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees. Therefore, we can set up an equation using the measures of the angles in triangle ABC:
ZABD + CBD + ABC = 180
Substituting in the given measures, we get:
(0.12x + 64) + (0.13x + 28) + ABC = 180
Simplifying and solving for x, we get:
0.25x + 92 + ABC = 180
ABC = 180 - 0.25x - 92
ABC = 88 - 0.25x
We know that the measure of angle ABC is 0.11x + 12. Substituting this into the equation for ABC, we get:
0.11x + 12 = 88 - 0.25x
Solving for x, we get:
0.36x = 76
x = 211.11
Therefore, the value of x is approximately 211.11.
Answer:
x = 352
Step-by-step explanation:
From the given Linear Pair, we can observe that ∠ABD and ∠CBD form a Straight Angle which is 180°.
∠ABD = 0.12x + 64°
∠CBD = 0.13x + 28°
Now we can understand that ∠ABD + ∠CBD = ∠ABC (Linear Pair)
∠ABC = 180°
So, ∠ABD + ∠CBD = 180°
(0.12x + 64°) + (0.13x + 28°) = 180°
(0.12x + 0.13x) + (64° + 28°) = 180° (Distribution Property)
0.25x + 92° = 180°
0.25x = 180° - 92°
0.25x = 88°
x = 88/0.25
x = 352

Step-by-step explanation:
38.13 inch² (Approximately)
Step-by-step explanation:The following figure has a Semicircle and a Rectangle.
The length of the Rectangle = 6 inches
The breadth of the Rectangle = 4 inches
Area of a Rectangle = Length * Breadth
= 6 * 4
= 24 inch²
Diameter of the Semicircle = 6 inches
Radius of the Semicircle = Diameter/2
= 6/2
= 3 inches
Area of a Semicircle = πr²/2
= 3.14 * 3²/2
= 3.14 * 3 * 3/2
= 3.14 * 9/2
= 1.57 * 9
= 14.13 inch² (Approximately)
Total area of the figure = Area of the rectangle + Area of the Semicircle
= 24 + 14.13
= 38.13 inch² (Approximately)
Hope my answer helps you.

What is the difference between factors of a number and multiples of a number?
Use the number 25 as an example.
Answer:
Factors are like numbers that are multiplied together to get that number
Using 25:
The factors of 25 are 1,5,25
1*25 = 25 and 5*5 = 25, so they are the factors of 25
Multiples are the products of the specified number and another number
Using 25:
Some of the multiples of 25 are 25, 50, 75, 100 and so on
25*1 = 25, 25*2 = 50, 25*3 = 75, 25*4 = 100, so they are the multiples of 25
Hope this helps!

Answer: 21.4 pounds
Step-by-step explanation:
To calculate the amount of weight that is made up of body fat, you need to multiply the weight by the body fat percentage.
Weight of body fat = 162 pounds x 13.2% = 21.384 pounds
Then, round it to the nearest tenth which is, 21.4
Therefore, approximately 21.4 pounds of the individual's weight is made up of body fat.
Answer: 21.4 lb
Step-by-step explanation:
The question is asking how much weight consists of body fat.
We know that 13.2% of the total weight is body fat, and the total weight is 162 pounds.
Multiply to find out the body fat weight.
Percentage as a decimal over 1 * 162
0.132 * 162 = 21.384 lb
Round to nearest tenth: 21.4 lb
