Answer:
you have to find the smallest common denominator
Step-by-step explanation:
so once the fractions have the same denominator you can add them easily and simplify
Answer:
n = 21
Step-by-step explanation:
5(n-7)=2(n+14)
Distribute
5n -35 = 2n+28
Subtract 2n from each side
5n-2n -35 = 2n-2n +28
3n-35 =28
Add 35 to each side
3n-35+35 = 28+35
3n = 63
Divide by 3
3n/3 = 63/3
n =21
Step-by-step explanation:
y > -15
y is bigger than -15
= -14 , -13 , -12 , -11 , -10 , etc . . .
Answer:
angle 4 and angle 8
angle 3 and angle 5
Step-by-step explanation: the pair of angles on one side of the transversal and inside the two lines are called the consecutive interior angles
so, angle 4 and angle 8
and angle 3 and angle 5
are consecutive interior angles.
40°, 60° and 80°
sum the parts of the ratio 2 + 3 + 4 = 9
The sum of the angles in a triangle = 180°
Divide 180 by 9 to find one part of the ratio
= 20° ← 1 part of the ratio
2 parts = 2 × 20 = 40°
3 parts = 3 × 20 = 60°
4 parts = 4 × 20 = 80°
The angles in the triangle are 40°, 60° and 80°
