Answer:

The input is -5 when the output is -8

Step-by-step explanation:

Let

y-----> the output

x ----> the input

we know that

The linear equation that represent this problem is

y=3x+7

so

For y=-8

substitute in the equation and solve for x

-8=3x+7

Subtract 7 both sides

-8-7=3x\\-15=3x

Divide by 3 both sides

x=-5

therefore

The input is -5 when the output is -8

Jim have the shopkeeper six coins that totaled 38 cent for a balloon what were the six coins
Katyanochek1 [597]

We are given that

Shopkeeper has six coins

total number of coins =6

we know that

there are four types of coins

(1) cents

1 cent =1 cent

(2) nickels

1 nickel =5 cents

(3) dimes

1 dimes =10 cents

(4) quarters

1 quarter = 25 cents

so, we can use trial and error method

Since, nickels , dimes and quarter are multiple of 5

and there 38 cents

so, three coins must be cent

number of cent coins =3

so, the remaining cent = 38-3=35

so, possible coins can be 1 quarter and 2 nickels

1 quarter + 2 nickels =25+2(5)=35

so, coins were

Number of cents =3

Number of nickels =2

Number of dimes =0

Number of quarter =1..................Answer
