Answer:
The original price of the item is $28.
Step-by-step explanation:
So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.
So:
First convert 25% to a decimal, 0.25.
OP(original price) = 21 ÷ 1 - 0.25 =
1 - 0.25 = 0.75
21 ÷ 0.75 = 28.
Answer:
x = 15
Step-by-step explanation:
Cameron started with 20 pieces of gum and gave away x number of pieces.
Cameron = 20 - x
Connor started with 35 pieces of gum and gave away twice as many as Cameron did.
Connor = 35 - 2x
Equate both Cameron and Connor expression
20 - x = 35 - 2x
Collect like terms
20 - 35 = -2x + x
-15 = -x
Divide both sides by -1
15 = x
x = 15
Check:
Cameron = 20 - x
= 20 - 15
= 5
Connor = 35 - 2x
= 35 - 2(15)
= 35 - 30
= 5
Answer:
(-5,9)
Step-by-step explanation:
7 + 2 is 9 so yeah that's it
I take it you want me to answer number eight? So, start with the side being twice the width- this is represented as 2x. Then, right before that, the problem states two more than- this is represented as +2. Your final equation should be 2x+2
Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46
