Answer:
first one is x=3
Step-by-step explanation:
R = 5(CA - 0.3)
<span>Multiply everything in the parenthesis by 5.</span>
R = 5CA - 1.5
Add 1.5 to both sides
1.5 + R = 5CA
Divide 5A on both sides.
C = 1.5 + R / 5A
Hope this helps!
Answer:
$612
Step-by-step explanation:
Each side of the square garden is 17 meters, and fencing costs $9 per meter. "Around" is the key word, as it indicates perimeter. So, we just need to account for each side of the garden, and not the entirety of the garden. So,
17 · 9 = 153
This means that to cover one side of the garden, it would cost $153. Now, we just need to account for all sides of the garden.
153 x 4 = 612
Option C ,
40 degrees
Because angle Z was 70 (isosceles triangle)
Then 180-140=40 degrees
