-5.2k+2.9 =-12k+30.1
Please show work !
answer: 3.8857
explanation:
Simplifying
-5k + 2.9 = -12k + 30.1
Reorder the terms:
2.9 + -5k = -12k + 30.1
Reorder the terms:
2.9 + -5k = 30.1 + -12k
Solving
2.9 + -5k = 30.1 + -12k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '12k' to each side of the equation.
2.9 + -5k + 12k = 30.1 + -12k + 12k
Combine like terms: -5k + 12k = 7k
2.9 + 7k = 30.1 + -12k + 12k
Combine like terms: -12k + 12k = 0
2.9 + 7k = 30.1 + 0
2.9 + 7k = 30.1
Add '-2.9' to each side of the equation.
2.9 + -2.9 + 7k = 30.1 + -2.9
Combine like terms: 2.9 + -2.9 = 0.0
0.0 + 7k = 30.1 + -2.9
7k = 30.1 + -2.9
Combine like terms: 30.1 + -2.9 = 27.2
7k = 27.2
Divide each side by '7'.
k = 3.885714286
Simplifying
k = 3.885714286

Answer:
72, 73
Step-by-step explanation:
माना दो क्रमागत धनात्मक पूर्णाक x और (x + 1) हैं |
इसलिए...
प्रश्नानुसार,
x + (x + 1) = 145
2x + 1 = 145
2x = 145 - 1
2x = 144
x = 144/2
x = 72
x + 1 = 72 + 1 = 73
3. The sum of two numbers is 30 and their difference is 12. Find the two numbers.
Answer:
I don't know is it 12 and 16 I'm not sure
Answer:
The two numbers are 21 and 9
Step-by-step explanation:
Let the two numbers be a and b
The sum of these numbers is 30
a+b=30
The difference between these numbers is 12
a−b=12
―――――――――
I. You can solve this by logic.
If the two numbers were exactly equal, then they would both be 15.
15+15=30
But the difference would be 0, not 12
So if you lowered b by one point, and added that to a, then the two numbers would be 16 and 14, and the difference would be 2.
So you can see that for every point you subtract from b to add to a, you increase the distance between them by 2
So, by logic, you need to subtract 6 points from b and add them to a to create a difference of 12
(15+6) minus (15−6) gives a difference of 12
.m21.....−mm∩9 = 12
Answer:
The two numbers are 21 and 9
―――――――――
II. You can solve this by math
These are simultaneous equations, so you can solve them by math.
.a+b=30
.a−b=12
――――――
2a +0=42
.a =21 ← same answer
-3 - 8 (-5x - 1) distributive property
Answer:
5 +40x
Step-by-step explanation:
Distributive property:a*(b +c) =(a*b) + (a*c)
-3 - 8( -5x - 1) = -3 + (-5x)*(-8) + (-1) * (-8)
= -3 + 40x + 8
= -3 + 8 + 40x {combine like terms}
= 5 + 40x

The data set below shows the number of points scored by a basketball team for each of nine games. If the mean of the data is 83 and the standard deviation is 6.5, identify all the scores that are within one standard deviation of the mean. {71, 77, 79, 80, 83, 87, 88, 90, 92}
Answer:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
Step-by-step explanation:
The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:
Between
83 - 6.5 = 76.5
83 + 6.5 = 89.5
So:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
sam ran 63,756 feet in 70 minutes what is sams rate in miles per hour
Answer:
His rate would be 910.8 miles per hour

This is division so divide 63756 by 70 and there’s your answer
Answer:
10.35 miles per hour
Step-by-step explanation:
63,756/5280 = 12.075 miles
12.075/70 = 0.1725 miles per minute
0.1725 x 60 = 10.35 miles per hour

The Jackson family went to soups and wiches and bought four sand which sand three bowls of soup for $27. The frank family went to soups and wiches and bought one bowl of soup and five sandwiches for $25.50. Let w represent the cost of the sandwich CNN es and a represent the cost of a bowl of soup. Identify which system of equations represents the situation.
Answer:
4w + 3c = $27
5w + c = $25.50
Step-by-step explanation:
Let us assume the w represent the cost of the sandwich
And, the c represent the cost of the bowl in a soup
Now the equations are
4w + 3c = $27
5w + c = $25.50
These two should be the equations that represent the situation

Answer:
Width 2in
height 3in
length 4in
Step-by-step explanation:
If he want the length to be four he has to take 2 sqares off at the end to be left with his height as 3 so vertical from top to bottom and width (the two sqaures at the end of the photo to the left) would be 2. :)
Width of box=2in
Height of box=3in
Length of box=6in
Volume=2(3)(6)=36in³Now
length of the box is 4in
Product of width and height=36/4=9in²
They must be of 3×3 in or 4.5×2 in

is the product of 3/6×5/4 equal to the product of 3/4×5×6? explain how you know
Answer:
yes
Step-by-step explanation:
I think you mean
"Is the product of 3/6 × 5/4 equal to the product of 3/4 × 5/6?"
If we can turn 3/6 * 5/4 into 3/4 * 5/6 using only legal math steps, then the answer is yes.
3/6 * 5/4 =
Breakup each fraction into a product of fractions.
= 3/1 * 1/6 * 5/1 * 1/4
Use the associative and commutative properties of multiplication to change the order and grouping of the multiplication.
= (3/1 * 1/4) * (5/1 * 1/6)
Do each product in parentheses.
= 3/4 * 5/6
This shows that 3/6 * 5/4 = 3/4 * 5/6
