Ten pounds of sugar costs 2.5 pounds
Step-by-step explanation:
First, you should combine the x terms:
-3x - 7 = 29
Then, get rid of the negative 7, by adding 7 to both sides.
-3x = 22
Finally divide 22 by -3, to solve for x.
x = -22/3 or -7.33
Answer:
your answer is the 2nd one
Step-by-step explanation:
Let x = total sales of baked goods remember 20% = .20 as a decimal
so the equation would be .20x = $600
divide both sides by .20
.20x/.20 = $600/.20
x = $3000 the total sales of baked goods
CHECK: 20% times $3000 = .20 times $3000 = $600
