So the equation is 2x + y = 9
you want to solve the equation so that y is on one side. in order to do this you need to subtract 2x from BOTH sides to get y by itself.
after, you should get y = 9 - 2x
Answer
A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is : a to b, a over b, and a:b
This is the concept of volumes of solid figures;
To calculate for the volume of material required we calculate for the volume of the pyramid;
volume of the pyramid is given by:
volume=(length*width*height)/3
but in our case the base of the pyramid is square, therefore:
length=width=2 ft
height=6 ft
hence;
volume=(2*2*6)/3
volume=8 ft^3
The answer is 8 ft^3
Maximum number of mangoes that Camila can buy are 5
Step-by-step explanation:
- Step 1: Find the cost of 8 apples bought by Camila.
Cost of 1 apple = $0.50
Cost of 8 apples = $0.50 × 8 = $4
- Step 2: Find the remaining amount with Camila after she bought 8 apples.
Total amount that can be spent = $7.75
Cost of apples = $4
Remaining amount = $7.75 - $4 = $3.75
- Step 3: Find the number of mangoes she can buy
Cost of 1 mango = $0.75
Number of mangoes = $3.75/$0.75 = 5
I believe the answer is population Hope this helped=) <span />
