It's scientific notation, so 1.4x10^7 would be 14000000 <span />
Answer:
Mom: $30
Charlie: $10
Step-by-step explanation:
You have to find how much percent of 40 for the price that they each pay.
His mom pays 75%, so that is $30.
And Charlie has to pay $10 because that is how much is left.
Anything multiplied by one is the same so it wold stay at 2 2/3
Let W = width of poster
Since the length is 7 inches longer than the width, the length is represented by W + 7.
We know the perimeter is equal to twice the length + twice the width and that is 110 inches. Mathematically that looks like:
2(W + 7) + 2(W) = 110
Now let's solve for W:
2(w+7)+2w=110
Step 1: Simplify both sides of the equation.
2(w+7)+2w=110
Simplify: (see simplify steps down below)
4w+14=110
Step 2: Subtract 14 from both sides.
4w+14−14=110−14
4w=96
Step 3: Divide both sides by 4.
4w4=964
w=24
Answer:
w=24
Simplify Steps:
(2)(w)+(2)(7)+2w=110(Distribute)
2w+14+2w=110
(2w+2w)+(14)=110(Combine Like Terms)
4w+14=110
Answer:
$10.35
Step-by-step explanation:
this is the answer because you have to multiply 9*.15=1.35. then that is the sales tax then you have to add it to the $9 so then you got $10.35
