How to solve 7m + 2n = 21 and 10m + 4n = -10 using substitution. Step by step please and thank you!
ryzh [129]
7m+2n=21
-7m      -7m

<u>2n</u>=<u>21-7m</u> 
2        2

n=<u>21-7m
</u>       2
<u>
</u>10m+4(21-7m/2)= -10
<u />-10m                   -10m

4(21-7m/2)= -10-10m

(84-28m/2)= -10-10m
    x2                x2

84-28m    = -20-20m
+20+28m   +20+28m

<u>104</u> = <u>8m
</u>8         8

m=13

10(13) + 4n = -10
-130              -130

<u>4n</u> = <u>-140
</u>4         4
<u>
</u>n= -35

Margo traveled 528.8 miles on her trip. Write a statement that compares the values of the ones and tenths digits
gavmur [86]

Answer:

In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place

Step-by-step explanation:

we have

The number 528.8 miles

Rewrite the number in digits value

528.8=500+20+8+0.8

so

The value of the ones digit is 8 ones or 8

The value of the tenths digit is 0.8 tenths or 0.8

Find the quotient

8/0.8=10

therefore

In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place
