Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
Answer: D
Step-by-step explanation:
3(1+x)+7 = 3+3x+7 =3x+10
Y=mx+b
m=slope
solve for y
5y=x-3
divide both sides by 5
y=(1/5)x-(3/5)
slope=1/5
C is answer
Answer:
8 inch
Step-by-step explanation:
radius is half the diameter
No it doesn’t. This is because if you have a negative number and multiply it by itself 3 times, you’ll still have a negative number (-1 times -1 times -1 is still -1). On the other hand, if you take a negative number and multiply it by itself twice (-1 times -1) you’ll have the answer that is positive (1).
