The answer is 2.25
1) simplify the fraction
25/100 = 1/4
2) then turn 1/4 into a decimal
1/4 = .25
3) then add
2+0.25= 2.25
Answer:
8.
Step-by-step explanation:
I think you have to multiply across.
The measures of the angles of the isosceles triangle are 55, 55 and 70.
Explanation:
An isosceles triangle has two congruent base angles and a vertex angle.
Let
b
=the measure of one of the base angles.
Let
v
=
the measure of the the vertex angle.
The vertex angle is 40 degrees less than the sum of the base angles.

Answer:
D. y=-3x-6
Step-by-step explanation:
line slopes downwards by 3 and moves to the right by 1. this means the slope is -3. the line crosses the y axis at -6, so the equation for the line is -3x-6
