To set up the equation you would take x and add the nine pounds that Charlie weighs more than his brother and the set that equal to 99. Your equation would be X+9=99. If you wanted to take it a step further and solve the equation you would distract 9 from both sides which means that x=90
Answer:
I just started
Step-by-step explanation:
First you should round the numbers that you are multiplying so.
56 ---> 60
27---> 30
You know that 5 and higher you'll round up.
4 and below you'll round down.
Answer:
n = 3
Step-by-step explanation:
Step 1 :
1
Simplify —
2
Equation at the end of step 1 :
1
(— • (2n + 4)) - 5 = 0
2
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
2n + 4 = 2 • (n + 2)
Equation at the end of step 3 :
(n + 2) - 5 = 0
Step 4 :
Equation at the end of step 4 :
n - 3 = 0
Step 5 :
Solving a Single Variable Equation :
5.1 Solve : n-3 = 0
Add 3 to both sides of the equation :
n = 3
One solution was found :
n = 3
