Answer:
x=5
Step-by-step explanation:
x+5 = -3x+25
Add 3x to each side
x+3x+5 = -3x+3x+25
4x +5 = 25
Subtract 5 from each side
4x+5-5 = 25-5
4x = 20
Divide each side by 4
4x/4 = 20/4
x =5
Answer:
d
Step-by-step explanation:

Nah this is easy. LQM is a rough estimate of 4050, which every angle is 70 degrees because it’s an acute triangle
Answer:
Perimeter of the paperboard that remains after the semicircle is removed = 94.26 in
Step-by-step explanation:
Watch the attached figure of how the semi circle is cut out of the rectangular paperboard.
Length = 24 in
Width = 18 in
Radius of the semi circle = Half of the width of the paperboard =
= 9 in
1) Circumference of the semi circle = π*radius
= 3.14*9
= 28.26 in
2) Perimeter of the paperboard that remains after the semicircle is removed
= Top + Left + Bottom + Right Circumference of the semi circle
= 24 + 18 + 24 + 28.26
= 94.26 in
It would be 9 buddy. Negative divided by negative turns into positive. 45 divided by 5 is 9.
