2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
Answer:
x=8
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 10^2
36 + x^2 = 100
Subtract 36 from each side
36-36 +x^2 = 100-36
x^2 = 64
Take the square root of each side
sqrt(x^2) = sqrt(64)
x = 8
An exponent is the number or value being raised to a power.
Hi there!
<u>Here are all the steps into solving this equation :</u>
<u>- 8</u> = 5.4
Add 8 on each side of the equation → 5.4 + 8 = 13.4
= 13.4
Multiply each side of the equation by 5 → 13.4 × 5 = 67
9z <u>+ 4</u> = 67
Subtract 4 from each side of the equation → 67 - 4 = 63
<u>9</u>z = 63
Divide each side of the equation by 9 → 63 ÷ 9 = 7
z = 7
There you go! I really hope this helped, if there's anything just let me know! :)
