Answer: 9</h2>
Step-by-step explanation:
I like to write out a multiplication of the lowest factors for each of the numbers and then compare them to find what might be the Greatest Common Factor.
Now,
36 = 2 × 2 × <u>3 × 3</u>
45 = <u>3 × 3</u> × 5
63 = <u>3 × 3</u> × 7
∴ the GCF is 9.
So, first turn your fractions into decimals. ⅞ = 0.875 which rounded is 0.88. 4/5 = 0.8. Next, put the decimals into the equation to replace the fractions. 0.88 + 4.2 - 0.8. Next solve the problem. So 0.88 + 4.2 = 5.08. Now your equation should look like this 5.08 - 0.8. Then subtract 0.8 from 5.08 which gives you 4.28. So 4.28 is your answer.
Answer:
The value of the gift card = v = $40
The visit to the skate cost = $8
The number of visits = n
∴ n = the value of the gift card over the cost of one visit to the skate
∴ n = v/8 = 40/8 = 5
Step-by-step explanation:
The general function for relating the value of the gift card, v, in terms if the number of visits, n. ⇒⇒⇒ v = 8n
