-3x+5y=30
+3x+5y=30
5y=3x+30
divide 5 by everything
answer: y=3/5x+6
1) (green)
A = 1/2(4+8)(6)
A = 1/2(12)(6)
A = 36
2) (pink)
A = 1/2(8+16)(14)
A = 1/2(24)(14)
A = 168
Answer:
B. 16/25 x is the answer
Step-by-step explanation:
lets find the proportional relationship,
y = kx
2/5 = k * 5/8
k = (2/5) / (5/8)
k = 16/25
so if k, constant is 16/25
<u>equation is:</u>
<em>y = 16/25 x</em>
Answer:
7.4 in
Step-by-step explanation:
Surface area of a cube = 6s²
(where s is the side length)
Given:
Substituting the given value into the formula and solving for s:
⇒ 328.56 = 6s²
⇒ 328.56 ÷ 6 = 6s² ÷ 6
⇒ 54.76 = s²
⇒ s = √54.76
⇒ s = 7.4 in
First, you subtract 16r by 9r, which gives you 7r, so that leaves you with 8 + 7r. You cannot add a normal number and a number with a variable, so that's all you can do, so your answer is A.
