Answer:
Step-by-step explanation:
It looks like you want to simplify the sums.
1. (3r -4) -(-5b -3) = 3r -4 +5b +3 = 5b +3r +(-4+3)
= 5b +3r -1

2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)
= 2k +5
__
3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)
= -13k +2
Answer:
7 rides
Step-by-step explanation:
Entry Fee = $3.60
Cost per ride = $1.50
$15 - $3.60 = $11.40
$11.40 ÷ $1.50 = 7.6 rides
Ans. = 7 rides
Therefore, Heather can only ride 7 rides leaving her with $0.90¢ change.
If B is a complement of A this means that the sum of the measures of A and B is 90 degrees.
mA + mB = 90
mB =90 - mA
mB = 90 - 40 = 50
Thus, the measure of angle B is 50 degrees.
If C is a supplement of B then, the sum of the measures of B and C is 180 degrees.
mC + mB = 180
mC = 180 - mB
mC = 180 - 50 = 130
Therefore, the measure of angle C is 130 degrees.
Since the father weighs 174 lbs on earth and 29 lbs on the moon we divide 174 by 29 to get 6 so we divide 108 by 6 to get 18lbs
