Answer:9

Step-by-step explanation:

First, you simplify to get -t=9t-90

Then you bring -90 over to the left side to get positive and bring the -t to the right to get: 90=10t

Now it is simple division where you divide 10 on both sides and get 9 for t

True or false 120% of a whole number is always greater than the number? and why?

Stells [14]

I can only use math to explain it. What is 100%?
100% = $\frac{100}{100}$
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = $\frac{120}{100} * 10$ = 12
is it greater than 10.

Find an equation of variation in which y varies directly as x and y=1 when x=0.5. Then find the value of y when x = 14.

FromTheMoon [43]

The value of y is twice that of x, so the equation is y = 2x.

Substituting in x = 14, we get y = 2(14) = 28.
