Answer:7
Step-by-step explanation:
8+4=12
2(x-1)= 2x-2
12=2x-2
now add 2 to both sides
14=2x
And divide both sides by 2
7=x
Answer:
$18 :)
Step-by-step explanation:
10% of 180 is 18
Angles x and 64 deg are "complementary," so x+64=90, and x= 26 deg.
Dear Westbrookalisha, your question is very vague. I don't see the worksheet or the problem you want us to solve.
Let us consider the second number would be 
The first number is eight more than the second one.
That is, the first number would be 
Three times the second number would be 
Twice the first number would be 
Now write the statement in mathematical form: "Three times the second number plus twice the first number is equal to 26"

Solve this equation for x:
Distribute 2 in
, we get

Combine the like terms,

Subtracting 16 on both sides,


Dividing 5 on both sides,

So the second number is 
Now find the first number:
First number 
Thus the numbers are 10 and 2.
