3.9x + 1.4 = 17 what is the steps​
Vedmedyk [2.9K]

Answer:

x=4

Step-by-step explanation:

3.9x + 1.4 = 17

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

3.9x*10+1.4*10=17*10

39x+14=170

Subtract 14 from both sides:

39x+14-14=170-14

39x=156

Divide both sides by 39:

\frac{39x}{39}=\frac{156}{39}

x=4

Blake has some quarters and dimes. He has 20 coins worth a total of $2.90. How many of each type of coin does he have?
Veronika [31]
Q=number of quarters
d=number of dimes

so the value of 1 quarter=0.25 and 1 dime=0.10 so therefor the total value would be
0.25q+0.1d=2.9

total number of coins=20
q+d=20

solve
we have
0.25q+0.1d=2.9 and
q+d=20
multiply the first equation by 10
2.5q+1d=29

so we have
q+d=20
2.5q+d=29

multiply first by -1 and add
-q-d=-20
<u>2.5q+d=29  +
</u>1.5q+0d=9
1.5q=9
multipliy both sides by 2
3q=18
divide by 3
q=6
subsitute
q+d=20
6+d=20
ubtract 6
d=14

14 dimes
6 quarters
