Remember you can do anything to an equation as long as you do it to both sides


15-1t+8t=-13
15+7t=-13
minus 15 both sides
7t=-28
divide both sides by 7
t=-4



4a+11-1a=2
3a+11=2
minus 11 both sides
3a=-9
divide by 3 both sides
a=-3

15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4

4a + 11-a = 2
3a = 2-11
3a = -9
a = -3

ms. eskew's class had a class average of 77 % on their math test. how would this be written as a ratio? a. 23:100 b. 77:100 c. 5
valina [46]
Writing in percentages is actually writing a fraction with 100 on its denominator.
By doing so, we can easily compare data.
For example 1/2 may be written as 50/100 and it is denoted by 50%.

So, in your question, 77% means 77/100.
Since fractions represent ratios, writing in ratio form, we get 77:100. The answer is (b)77:100

  h(3) = h(1) +h(2)

  h(3) = -6 +20 . . . . . substitute the given values
