Three times the sum of a number and seven is two less than five times the number.

Answers

Answer 1

Answer: 3 (x + 7) = 5x - 2
3x + 21 = 5x - 2
3x - 5x = -2 - 21

-2x = -23
x = -23/-2
x = 23/2

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?

Answers

Let

n-------> the number of nickels

d-------> the number of dimes

we know that

$1\ nickel=\$0.05$

$1\ dime=\$0.10$

$0.05n+0.10d=13.30$ -----> equation A

$n+d=175$

$d=175-n$ -------> equation B

substitute equation B in equation A

$0.05n+0.10(175-n)=13.30$ ------> equation that can be used to find n

Solve for n

$0.05n+17.5-0.10n=13.30$

$17.5-13.30=0.10n-0.05n$

$0.05n=4.2$

$n=84\ nickel$

find the value of d

$d=175-n$

$d=175-84=91\ dimes$

therefore

the answer is

The equation that can be used to find n is $0.05n+0.10(175-n)=13.30$

The number of nickels in the collection is $84\ nickel$

n + d = 175 .... d = 175 - n
0.05n + 0.10d = 13.30

0.05n + 0.10(175 - n) = 13.30 <== and u would just solve for n
