Answer:
x = 7
Step-by-step explanation:
We are told one quarter of x is equal to 7 , then the equation is
x = 7 ( multiply both sides by 4 to clear the fraction )
x = 28
You can skip 4 in that equation and you'll be left with 2x+12=0, which gives you 2x=-12 and finally, x=-6
Assuming that Ralph budgeted $180 instead of $175 entertainment. He spent $35 per date and let "x" be the number of dates he attended. He spent $15 to go out with friends and let "y" the number of times that he go out with friends.
The correct expression is the "B" which is 35x + 15y =180.

So, (-1-8)/(-3-(-9)) = -9/6 = -3/2
Answer:
TU= 4 mm
Step-by-step explanation:
a^2+b^2=c^2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
