Answer:

32+78+x=180

Step-by-step explanation:

All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.

Sally has twice as many dimes as nickels. The total value is $3.50 how many nickels and dimes does she have?
Murljashka [212]
D=2n
.05n+.1d=3.5
I multiplied the nickels and dimes by these values because that is their actual monetary value 
.05n=3.5-.1d
multiply everything by 20
n=70-2d
d/2=70-2d
.5d+2d=70 
2.5d=70
d=28 
n=14 
so there are <u>28 dimes and 14 nickels 
</u>
checking this answer 
28 dimes = $2.8
14 nickels = .70
2.8+.7=3.5
