Answer:
20:a , a=48
Step-by-step explanation:
5*4=20, 12*4 = 48
Simple mathematics, you multiple 5 by 4 to get 20, do the same thing to 12.
Rate is miles/gallons
132/11=12 mile pser 1 galon
ratio and propeortion
132/11=252/xgalons
12/1=252/x
multiply both sides by x
12x=252
divide both sides by 12
x=21
21 gallons
The leaf of the number 392 would be. 2 cause there can be a lot of numbers that begin 39. Example:-
Plot 389, 392, 395, 351, 408 on a stem-and-leaf plot:-
Stem| Leaf
35 |1
38 |9
39 | 2 5
40 | 8
Hope I helped ya!
The answer would be A) $79.20
(220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9
The slope is negative one half because perpendicular lines always have slopes that are opposite reciprocals
meaning not only are they reciprocals meaning 1 over the number (or flipping the numerator and the denominator of a fraction) you also change the sign
