A climbing gym charges $10 to climb each day.A pair. of climbing charges shoes cost $84.It costs $169 to buy 6 days of climbing,one pair of climbing shoes,and one harness.How much does a harness cost? WRITE AN EQUATION FOR EACH PROBLEM. USE A VARIABLE FOR THE UNKNOWN NUMBER. SOLVE.

Answers

The equation representing the given problem is:

6x + y + z = 169

A harness costs $25

Let the charge for 1 day of climbing be represented by x

x = $10

Let the price of 1 pair of climbing shoes be represented by y

y = $84

Let the price of 1 harness be represented by z

It costs $169 to buy 6 days of climbing, one pair of climbing shoes, and one harness

Total cost = $169

The equation representing the given scenario is:

6x + y + z = 169

To find the value of z, substitute x = 10 and y = 84 into the equation

6(10) + 84 + z = 169

60 + 84 + z = 169

144 + z = 169

z = 169 - 144

z = 25

Therefore, a harness costs $25

The correct answer is:

The harness is $25.

Explanation:

Let x represent the cost of the harness.

Each day of climbing is $10. This means 6 days of climbing is represented with 10(6). The shoes are $84. This makes our expression 10(6)+84. Adding the harness, x, to that, our total comes to $169. This gives us the equation

10(6)+84+x = 169

Simplifying the left hand side, we have

60+84+x = 169

Combining like terms, we have

144+x = 169

Subtract 144 from each side:

144+x-144 = 169-144

x = 25

The harness is $25.

3÷0.1=30Choose all of the statements that explain how the quotient relates to the dividend.Dividing 3 by 0.1 tells how many tenths are in 3 ones.3÷0.1 is the same as 30÷1, which is 30.It takes 10 tenths to make 1 whole, so it will take 3 times 10 tenths to make 3 wholes. 3×10=30.The quotient has 110 of the value of the dividend so the dividend must be 10 times greater.The 3 in 30 is 1 place to the right of the 3 in the whole number 3 which increases the value of the number 10 times.
