Answer:
4m - 15
Step-by-step explanation:
a( x + y) = ax + ay
Assuming -5 is m
y-3 = -5 (x + 7)
y - 3 = -5x - 35
y = -5x - 33

Answer:
0.75 is the answer
Step-by-step explanation:
6/8 is equivalent to 3/4
3 divided by 4 is 0.75
Since 6/8 is equivalent then it is also 0.75
Also 6/8 turn to 3/4 when both the numerator and denominator is divided by 2.
6 divided by 2 is 3
8 divided by 2 is 4
33km total / 3 hours total = 11 km/hr average
Step-by-step explanation:
Question 10 :
3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)
simplify and get x, thus x = 18
to find 3x + 6 or 4x - 12(which is both the same),
3(18) + 6 = 60° , 4(18) - 12 = 60°
Question 11:
2x + 24 + x = 180 ( reason: interior angles due to parallel lines)
simplify again to get x, you will get x = 52
then find the individual by subbing in the value of x into the equation.
so 2x + 24 = 2(52)+24 = 128° and x = 52°
