Answers

Answer 1

A = small box of oranges

B = large box of oranges

3A + 14B = 203

11A + 11B = 220

Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:

[tex]\frac{11A+11B}{11}[/tex] = A + B

220 will also have to be divided by 11, giving you 20

A + B = 20

You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.

11B = 143

143/11 = 13

B (large box of oranges) costs $13.

Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60

3A + 3*13 = 60

3A + 39 = 60

3A = 21

A = 7

Thus:

A small box of oranges costs $7, and a large box of oranges costs $13.

Hope this helped! (please brainliest)

Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.

Answers

Answer:

So, the first solution is a calculator but sometime we don't have a calculator so, do

200 X 300 = A

40 X 90 = B

9 X 8 = C

then add just do multiplication from there like

A + B = D

D + C = E

Then your finally answer would be E

Hope that helps that's the way I do math quick in my head

The design plans for a new concert hall show elevations relative to ground level at 0 feet. The elevation of the balcony floor is 37 feet, and the elevation of the basement floor is –17 feet.

Which TWO statements about the distances of the balcony and basement from ground level are true?
Select TWO that apply.

A
The basement floor is 17 feet above ground level.
B
The balcony floor is 37 feet above ground level.
C
The balcony floor is 37 feet below ground level.
D
The basement floor is 17 feet below ground level.

Answers

Answer: B and D

Step-by-step explanation:

-17 means below, so the basement floor is 17 below ground level, and no symbol means positive, meaning above, so the balcony is 37 feet above ground level.

B,D because negative (-) means below so it means the basement is 17 below and the balcony did 37 feet above

We know that Ravi has 124$, but we don’t need how much he spent! So, for the money he’s spent we are using B to represent it. The way I see the expression is:

124 - B = T

B is how much money he spent.
T is his total after.

I hope this helped! Good luck :D

9. Andrew was measuring the height of the tree in his yard. Four years after it was planted, the tree was 11 feet tall. Twelve years after the tree was planted, it was 21 feet tall. Assuming the tree was growing at a constant rate, create the equation that models that growth of the tree over time. Show or explain your reasoning. (HINT: Use the two points to find the slope and use point-slope form to create an equation.)

Answers

Answer:

y=10/8x+6

Step-by-step explanation:

This is because when you plot the points you can find the slope by using rise over run and by finding the slope you can find the y intercept and that is all you need for the equation.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear equations are:

2x+3y=8

6x−5y=−32

3X(2x+3y=8)

6x + 9y = 24

6x−5y=−32

14y = 56

y = 4

x = -2

Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

they should use 1.1 quarts more of yellow paint. 10% is 0.1 quarts and 30% is 0.3 quarts so yellow and blue combined would be 0.4 quarts. 1.5 quarts is needed, 1.5 - 0.4= 1.1 quarts
