Mathematics
1 answer:
stich3 [128]2 years ago
6 0

Answer:

X=7

Step-by-step explanation:

STEP 1: Simplify both sides of the equation

7x + -10 + 2x =39 + 2x

(7x + 2x) + (-10) = 2x + 39 (combine like terms)

9x -10 = 2x + 39

step 2: Subtract 2x from both sides

9x -10 - 2x = 2x + 39 - 2x

7x - 10 =39

Step 3: Add 10 to both sides.

7x - 10 + 10 = 39 + 10

7x = 49

Step 4: Divide both sides by 7.

7x/ 7 = 49/7   <u> x=7</u>

<u>hope this helps!!</u>

1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.

4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.

3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number
