1:The total earnings from mowing a lawn for 3 hours is $19.50. What equation can be used to model the total earnings for mowing a lawn x hours?

2:The ratio of students to adults at a school is 14 : 2. Suppose there are a total of 490 students. How many adults are at the school?

Answer 1

1.) 3x = 19.50 (they got 6.5 and hour)

2.) 70 adults

Explanation:

Work for #2

`(14)/(2)`
`(490)/(x)` then cross multiply. 14*x = 14x 490*2 = 980

So 980 = 14x (divide by 14)

x = 70

So 70 adults

Hope this helps!!!
