Answer:
step 1. you see in the problem x = 6y + 9 substitue the equation for the x variable in the first equation. so it will be 2(6y+9) - 12y = 7
step 2. solve for y. butttt in this case it looks like it can't be solved .
Step-by-step explanation:
option 3. in the steps i provided substituted x for x equals 6y + 9 which leads you to solve y. if you want you can rearrange 2x-12y=7 to solve for y so it would be 7-2x/-12 = 7
Answer:
A ≈ 75 in²
Step-by-step explanation:
the area (A) of the circle is calculated as
A = πr² ( r is the radius )
here r = 5 and using 3 for π , then
A = 3 × 5² = 3 × 25 = 75 in²
32b+12
32 and 12 is both divisible by 4 so divide them by 4 and the answers in parentheses
4(8b+3)
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. The area A of a rectangle with length l and width w is A=lw EXAMPLE
put that into a formula.... and boom solved just comment on this for the answer
Answer:
13 ounces
Step-by-step explanation:
First we find what 30% of 10 ounces is.
0.3*10 ounces=3 ounces
We add the answer to the original 10 ounces and we get 13 ounces.
Hope that is clear and good luck with homework
