Answer:
14
14
47
Step-by-step explanation:
An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.
5 + 3x + x + x = 75
5 + 5x = 75
5x = 70
x = 14
5 + 3(14) = 47
The mistake the student made in the second procedure is she tried to solve 3.7+2.6 the same way she solved 4.3+8.4, which that way doesn't always work. You have to understand how decimals work when it comes to adding them. The right way to solve 3.7+2.6 and be sure you are accurate is to line the numbers up. Then add the numbers behind the decimal which is 7+6. That equals 13. So you would out your 3 and carry your 1 over to the number in front of the decimal. So 3+2=5, plus the additional one you had to carry. Your final answer would be 6.3

Answer:
<h2> $24</h2>
Step-by-step explanation:
The question is not complete, here is the complete question
"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>
<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>
1/4 of $48= 0.25*48=$12
so he thought he should pay $12
1/4 off $48= $48-$12= $36
now the difference is
36-12= $24
