C - 7.6 = -4
c = -4 + 7.6
c = 3.6
Set the equations equal to each other and solve for the variable x. then use the answer from x and plug it in to the equations and you should get an answer
3x=63
63÷3=x
21=x
x=21
that is the value of x
73 is the answer to the top equation and the bottom equation in the triangle. Meaning the equations are equal to each other when you have 21 plugged in for the variable x.
make sure to put your label if it asks for it. it means the book or the teacher. go by what the teacher says if it is different from what the book says
Answer:
320 ft² (nearest whole number)
Step-by-step explanation:
Given:
- height of fence post = 8 ft
- diameter of fence post = 1 ft ⇒ radius = 0.5 ft
- total number of posts = 12
- π = 3.14
Surface area of a cylinder = 2πr² + 2πrh
⇒ SA of one fence post = 2 · 3.14 · 0.5² + 2 · 3.14 · 0.5 · 8
= 1.57 + 25.12
= 26.69 ft²
As there are 12 fence posts,
Total paint needed = 12 × 26.69
= 320.28 ft²
= 320 ft² (nearest whole number)
The better deal will be to get them from Walmart. In the 12 pack each card is approx. $1.40 when in Walmart each cart is approx. $1.39. So getting 6 pack from Walmart will be cheaper and a better deal.
There ya go. photo math is easier to use! hopefully this helps you!
