-2/3x + 5 = 20 - x
subtract 5 from each side
-2/3 x = 15 -x
add x to each side
-2/3 x +x = 15
get a common denominator of 3 for the x terms
-2/3x + 3/3 x =15
combine like terms
1/3 x = 15
multiply by 3 on each side
x = 45
Answer: x=45
Answer:
7) m = 6
8) k = 15
9) a = -12
10) x = 1
11) n = 4
12) r = 11
Step-by-step explanation:
<h3><u>Solution</u> : </h3>
Solving all the questions step by step!
7) 1 = 6+m/12
- Hence, the value of m is 6.
8) 8 = 3 + k/3
- Hence, the value of k is 15.
9) -4(-8+a) = 80
- Hence, the value of a is -12.
10) 8(x-1) = 0
- Hence, the value of x is 1.
11) n/2 - 1 = 1
- Hence, the value of n is 4.
12) 1 = r-3/8
- Hence, the value of r is 11.
I think the answer is 3x-y=11
If you add up all the terms, then divide the number of Red Delicious apples by the sum, then you should get your answer.
V = 4/3 * pi * r^3
V = 4/3 * pi * 8.4^3
Simplify exponent:
V = 4/3 * pi * 592.704
Multiply:
