Let's solve your equation step-by-step.
8.88=4.44(x−7)
Step 1: Simplify both sides of the equation.
8.88=4.44(x−7)
8.88=(4.44)(x)+(4.44)(−7)(Distribute)
8.88=4.44x+−31.08
8.88=4.44x−31.08
Step 2: Flip the equation.
4.44x−31.08=8.88
Step 3: Add 31.08 to both sides.
4.44x−31.08+31.08=8.88+31.08
4.44x=39.96
Step 4: Divide both sides by 4.44.
#2
= y = -3
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by 5.
First person = 10 min
Second person = 15 min
Time together = x
Equation Formation
x = (10+15) ÷2
x = 12.5
Answer = 12.5 minutes
Amount of Job done by the slowest person.
10/25 × 100 = 40%
Answer = 40%
10% of the movies, because 100/40 is 2.5 so you would do 4 x 2.5 which equals 10. AKA
So if you’re trying to change it to x/100, you would do cross division and get 10/100 which equals 10%
12/100 = 3/25
