Answer:
W = 5
L = 15
Step-by-step explanation:
Formula for Area of Rectangle is L × W
Since stated triple;
L = 3W
Area = L×W = 3W² = 75
It'll be:
3W² = 75
Divide both sides with 3:
<u>3</u><u>W</u><u>²</u> = <u>7</u><u>5</u>
3 3
W² = 25
Then square root both sides:
w = 5
Again stated that length is triple the width:
L = 5 × 3
L = 15
Therefore;
W = 5
L = 15
They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
5x3 − 6x4
So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you
hope it helps
Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675
We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175
When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103
Y=mx+b where m is slope. Since m = 0.11, the slope is 0.11
