Answer: x=18
Step-by-step explanation:
2/3 * x=12
2x=36
x=18
Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.

Answer:
Jack's linear speed is 126ft/min
Bob's linear speed is 176ft/min
Step-by-step explanation:
First of all, find the circumference of both circles given the radius; Jack, 2<em>pi</em>r (10)=63ft. Bob 2<em>pi</em>r(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.
Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3
Move the "%" two places to the left and replace it with a decimal
so it's 0.86
