Answer: x=-3
Step-by-step explanation:
First you add 3x+5x cause they are both variables.They equal 8x.
Then you subtract 7x from both sides to get x+17=10
then you subtract 17 from both sides.
you will get x= -3
Hope that helps!
Answer:
x = 107
Step-by-step explanation:
x and 107 are alternate interior angles and alternate interior angles are equal
so x= 107
Distribute the five to [3q-10]
Combine like terms [15q] and [-5q]
Add 50 on each side
Divide by 10 on each side
Simplify
Answer:
the answer to 0.4 cubed is 0.064
Let's assign variables
The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x
</span>
<span>y varies inversely as x
so that:

where k is the proportional constant
To calculate the value of k, plug in the values of x and y:
x=7
y=4

Now, write down the relation between x and y:

"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:

So it would take 9 hours and 20 minutes to have this job done.
