7m - 3m + 5 = 45
4m + 5 = 45
45-5 = 40
4m = 40
40/4
m = 10 minutes
Answer:
5.28 if you round to the nearest hundredth. Drop a best answer and a like if it helped
7x-3 = 18
+3 for both sides
7x = 21
devide 7 for both sides
x = 3
Distributive property is
a(b+c)=ab+ac
we can make it easier by splitting up 63 into 60+3
so
7(63)=7(60+3)=7*60+7*3=420+21=441
A.) 10x + 7.5 (0) =420
10x = 420
420 / 10 = 42
x = 42 > ( 42,0 )
10(0) + 7.5y = 420
7.5y = 420
420 / 7.25 = 56
y = 56 > ( 0,56 )
(42,0) (0,56)
B.) The x intercept means that there was 42 ,minutes spent biking. The y intercept means that there was 56 minutes spent in line skating.
C.) (21 ,28) - (14,37) - (28,18)
