A box contains 35 coins either nickels or dimes all worth $2.90. How many dimes are in the box?
tino4ka555 [31]

Answer:

There are 23 dimes in the box

Step-by-step explanation:

Let nickels=n

Let dimes=(35-n)

Equation: 0.05n+0.10(35-n)=2.90

Multiply both sides by 100: 5n+10(35-n)=290

-5n+350=290

-5n=-60

n=12

35-12=23

Therefore, there are 23 dimes in the box

Multiply 1 with 30,000: 30,000 x `1 = 30,000

30,000 metres is your answer.

B) Scale is 1 inch: 6 miles. You are given 2.5 inches.

Remember that 1 inch = 6 miles.

Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles

2.5 inch = 2.5 * 6 miles

2.5 inch = 15 miles

15 miles is your answer.
