Answer:
D)18
Answer:
Angle A = 100°
Angle B = 80°
Step-by-step explanation:
Supplementary angles means angles add up to 180°.
There are only two angles given here.
Angle A and Angle B add up to 180°.
A + B = 180°
4x + (2x + 30) = 180°
4x + 2x + 30 = 180°
6x + 30 = 180°
6x = 180 - 30
6x = 150°
x = 150 ÷ 6
x = 25°
Now substitute the x value to the angles.
Angle A:
4x
4(25) = 100°
Angle B:
2x + 30
2(25) + 30
50 + 30 = 80°
try using 2 and 5.. 2x{[(12-3)x3]+(5x6)-8}=98
Answer: 3c - 5
Step-by-step explanation:
Since c represent the number of cookies that Mark made. We are then informed that Peter made five less than triple as many cookies as Mark. This will be:
= (3 × c) - 5
= 3c - 5
The expression is 3c - 5
