System of equations?
Answer:
Good day sir
The answer is (3,7)
Step-by-step explanation:
One way is to graph the line
Another way is to do it the hard way
3x + y = 16 is y = -3x + 16
Add the original equations up and solve
2y = -x + 17
This is a start (just solve this equation) but the answer is (3,7)

Rembrandt framed his masterpiece. The painting by itself is a rectangle with length 20 \text{ cm}20 cm 20, start text, space, c, m, end text and width 16 \text{ cm}16 cm 16, start text, space, c, m, end text. The painting and frame together form a larger rectangle with length 25 \text{ cm}25 cm 25, start text, space, c, m, end text and width 20 \text{ cm}20 cm 20, start text, space, c, m, end text. Find the area of the frame.
Answer:
180cm²
Step-by-step explanation:
Area of the frame = area of the frame+ painting - area of painting.
Area of a rectangle = Length × Width
Area of the painting = 20cm×16cm
Area of the painting = 320cm²
Area of the paint+ frame = 25cm×20cm
Area of the paint+ frame = 500cm²
Area of the frame = 500cm²-320cm²
Area of the frame = 180cm²
Hence the area of the frame is 180cm²

4. Mike is making bread for a family reunion. He knows that he needs 5.25 cups of flour per loaf.
A. If mike needs 5 loaves and one smaller half loaf, how much flour will Mike need in all? (6 points)
B. If mike makes a small loaf for himself that is 0.75 times the regular loaf, how much flour will he need? (6 points)
Answer:
A. 7.87 cups for 5½ loads
B. 3.93 cups for the tiny loaf
Step-by-step explanation:
A. 5.25 divide by 2 = 2.62 (rounded)
5.25 + 2.62 = 7.87
B. 5.25 × 0.75 = 3.93 cups
5. Two blueberry farms are similar in shape. The ratio of the side lengths of
the farms is 5:6, and the smaller farm has a perimeter of 360 yards. The
cost to dig a trench is $0.75 per yard. What is the cost to dig a trench
around the larger blueberry farm?
Answer:It would cost $270 to dig
Step-by-step explanation:<!>Brainliest Apprecatied<!> :D
Answer: $324
Step-by-step explanation:
For this question, many people think the answer is 270, but that's wrong.
Since the ratio is 5:6 and the smaller farm perimeter we can put that into an ratio equation.
x will be the perimeter of the bigger farm
5/6=360/x
5x=2160
5x/5=2160/5
x=432 yards
That's the perimeter, now to find the cost it would be 432*0.75 which is $324.
The results of a recent survey indicate that the average new car costs $23,000 with a standard deviation on $3,500. The prices of the car are normally distributed. a. If someone buys a car for $32,000, what proportion of cars cost an equal amount or more than this? b. If someone buys a car for $16,000, what proportion of cars cost an equal amount or more than this?
Answer:
(a) 0.0051
(b) 0.9773
Step-by-step explanation:
Let X = prices of the car.
It is provided that [tex]X\sim N(23,000, 3,500^{2})[/tex].
(a)
Compute the value of P (X ≥ 32000) as follows:
[tex]P(X\geq 32000)=P(\frac{X-\mu}{\sigma}>\frac{32000-23000}{3500})[/tex]
[tex]=P(Z>2.57)\\=1-P(Z<2.57)\\=1-0.99492\\=0.00508\\\approx 0.0051[/tex]
Thus, the proportion of cars cost an equal amount or more than $32,000 is 0.0051.
(b)
Compute the value of P (X ≥ 16000) as follows:
[tex]P(X\geq 16000)=P(\frac{X-\mu}{\sigma}>\frac{16000-23000}{3500})[/tex]
[tex]=P(Z>-2)\\=P(Z<2)\\=0.97725\\\approx 0.9773[/tex]
Thus, the proportion of cars cost an equal amount or more than $16,000 is 0.9773.

I need help graphing 2x - 6y = 42 I'm just really lazy
Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

Emy paid 24.50 for 4 baskets of apples. How much did she pay for each basket?
Bonus: How much will it be for 10 baskets.
Please help me it will be very much appreciated!
Due in one hour.
Answer:
6.125
Step-by-step explanation:
Divide 24.50 by 4!
Answer:
$6.13 for each basket.
Bonus: $61.30 for ten baskets.
Step-by-step explanation:
To solve this, we would divide the $24.50 by four, because there are four baskets. We now know that she paid $6.13 (rounded from $6.125) for each basket. To solve for 10 baskets, you would take the price per basket of $6.13 and multiply it by ten, resulting in $61.30 for all ten baskets.
Hope this helps!

4. Jim makes 8.50 an hour. Each week, 26% of his total pay is deducted for taxes. How many hours does Jim have to work if he wants his take-home pay to be AT LEAST $300 per week? Write and solve an inequality for this situation.
Answer:
Jim has to work 48 hours to earn at least $300 per week.
Step-by-step explanation:
Jim makes 8.50 per hour
so in x hours he makes 8.5x
26% is deducted for taxes
so his take home pay is 8.5x(1 - .26) = 8.5x(.74) = 6.29x
To make > = $300 Jim must work enough hours so that
6.29x >= 300
x >= 17.49
what is the answer
Answer: B
Step-by-step explanation: The y-intercept is in the right place which is 5 and it is going up left to right because the slope is positive, not negative which is why D is incorrect and B is correct.

Find the value of x. -2x + 6 = 4(x + 6)
Answer:
x = -3
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
To find the value of x, you need to get rid of parentheses! So, 4*x=4x. 6*4=24. Now we have, -2x+6=4x+24. Then we want to get all the x on one side, and the other numbers on the other side. We can add -2x to make it 0, but to make it equal, you need to add it to the other side. So, 4x+2x=6x. You can subtract 24 too! After we do all that, we get: -18=6x. To get x, we need to divide by 6. 6x/6=x. -18/6=-3.
Calculate the mean ,median, or mode of a distribution. There are 10 bags containing tickets numbered 1 to 20. Ten students draw a ticket from each bag. One student drew tickets with the numbers. 5,8,18,1,14,6,8,13,8,19 what would be the correct mean, median, and mode
Answer:
Step-by-step explanation:
Mean = sum of variables/sample size
Sum of variables = 5+8+18+1+14+6+8+13+8+19
Sum of variables = 100
Sample size = 10
Mean = 100/10
Mean = 10
Median is the value at the centre after rearrangement.
On rearrangement
1,5,6,8),8,8,(13,14,18,19
Median = 8+8/2
Median = 16/2
Median = 8
Mode is the value with the highest frequency. The value that occur the most. From the datas, the mode is 8 since it occurred 3 times.
