Answer:
<h3>Given</h3>
- g varies jointly with h and j
- g = 4 when h = 1/2, j = 1/3
<h3>To find</h3>
- Value of g when h = 2 and j = 3
<h3>Joint variation:</h3>
- g = khj, where k- coefficient
Use given values of h and j, and find the value of k:
- 4 = k*(1/2)(1/3)
- 4 = (1/6)k
- k = 4*6
- k = 24
The equation is now:
Find the value of g when h is 2 and j is 3:
<u>Correct choice</u> is D
I think the answer is 2.98b
Let's solve your equation step-by-step.
7(x+2)=6(x+5)
Step 1: Simplify both sides of the equation.
7(x+2)=6(x+5)
(7)(x)+(7)(2)=(6)(x)+(6)(5)(Distribute)
7x+14=6x+30
Step 2: Subtract 6x from both sides.
7x+14−6x=6x+30−6x
x+14=30
Step 3: Subtract 14 from both sides.
x+14−14=30−14
x=16
Answer:
x=16
