Answer:
84
Step-by-step explanation:
72/x = 6/7
muliply by x on both sides
72 = 6/7x
mulitply by 7 on both sides
504 = 6x
divide by 6 on both sides
84
So paid160
75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost
rise over run
you can remember it doing the vertical over horizontal
Answer:
B. x = 15, m∠Q = 75°
Step-by-step explanation:
Given:
m∠P = 105°
m∠Q = 
Angles P and Q are supplementary angles
To find value of 
and m∠Q.
Solution:
[Sum of supplementary angles =180°]
[Substitution ∵ m∠P = 105° and m∠Q = ]
Subtracting both sides by 105°.
Dividing both sides by 5.
∴ 
∴ 
Based on the fact that you are allowed to multiply as many 2's and/ or as many 5's as you want, the last digit of your result can be either a 2, 5 or 0.
<h3>What is the last digit of your result?</h3>
If you multiplied a 5 number with another 5 number, you will either get a 0 as the last digit or a 5 as the last digit:
5 x 5 = 25
5 x 10 = 50
5 x 15 = 75
5 x 25 = 125
If you multiply a 5 with a 2, you result would always end in 0:
5 x 2 = 10
5 x 4 = 20
5 x 6 = 30
If you multiply a 2 with another 2, the result would be a 2:
2 x 2 = 4
2 x 4 = 8
2 x 6 = 12
