Move the five to the other side to make Make it a -5

then combine -7 to -5 to make it -12 anytime you subtract a negative number to a negative number you do the same thing as adding to it when you use a positive number to a negative number you flip it the other way

3x=-12 is how it should be set up if done correctly divide 3X to -12 which should solve X equals -4

Answer:

$44.55

Step-by-step explanation:

10% of 45 is 4.5

45 * 0.1 = 4.5

So subtract 4.5 from 45

45 - 4.5 = 40.5

Now get 10% of 40.5

40.5 * 0.1 = 4.05

Add 4.05 to 40.5

4.05 + 40.5 = 44.55

1. Given s = 3x +t/r

goldenfox [79]

Answer:

Step-by-step explanation:

1). s = $\frac{3x+t}{r}$

r.(s) = $r.(\frac{3x+t}{r})$

rs = 3x + t

rs - t = 3x

$\frac{rs-t}{3}=\frac{3x}{3}$

$\frac{rs-t}{3}=x$

$x=\frac{1}{3}(rs-t)$

2). 5ax + b = c

(5ax + b) - b = c - b

5ax = c - b

$\frac{5ax}{5a}=\frac{c-b}{5a}$

x = $\frac{1}{5}(\frac{c-b}{a})$
