Answer:
27. C
28. D
Step-by-step explanation:
The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.
Solving this equation gives:
[tex]\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105[/tex]
So D is the right answer for 28.

Answers
Answer:
105
Step-by-step explanation:
180-75=105
Answer:
75*
Step-by-step explanation:
Angles 4 & 8 are the same because the two parallel horizontal lines have one line going through them and angels 4 & 8 are in the same corner on the two lines. Also, angle 4 has a measure of 75* and if angles 4 & 8 are the same, they will also have the same measure.

Steps: multiplying the first equation by 2, we get 2x-2y=8. Adding that to the second equation we get 3x = 12. Dividing both sides by 3, we get x = 4. Substituting it into x-y = 4, we get y = 0.

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?
Answers
Answer:
Ariana is correct. The difference in the price is $3. So the percentage that you saved has to equal $3.
Step-by-step explanation:
$15.00 x .10 or 10% = $1.50
$1.50 x 2 will give you 20%
$1.50 x 2 = $3.00

To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75
Question 2:
We can write teh following equation

Mimi bought some fabric for a sewing project. The fabric cost $15.40 per meter. She bought 250 centimeters of fabric.
How much did Mimi pay for the fabric?
Answers
Answer:
$38.50
Step-by-step explanation:
so there are a hundred centimetres in a meter so u have to divide the 250 by 100
250 / 100 = 2.5 meters
and its 15.40 for 1 meter and she bought 2.5 so multiply those
15.40 * 2.5 = 38.50
she paid $38.50 for 2.5 meters of fabric
Answer:
$38.50
Step-by-step explanation:
There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!

Harvey is working on a weekly budget. He earns $459 per week. Harvey spends $200 per week on rent and utilities plus $85 per week on food. After paying for rent, utilities, and food, Harvey deposits 2/3 of the amount left over into a savings account. He can spend the rest of the money on entertainment.
How much money does Harvey have to spend on entertainment per week?
Answers
Answer: Harvey has $174 per week to spend on entertainment.
Step-by-step explanation: first Add the money he has throughout the week which is $200 + 85 =285 and just subtract $459 and 285.
A fraction is a way to describe a part of a whole. The money that Harvey has to spend on entertainment per week is $58.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Harvey earns $459 per week and spends $200 per week on rent and utilities, also $85 per week on food. Therefore, the amount of money left with Harvey,
Amount left with Harvey
= Earning - spending on rent and utilities - spending on food
[tex]\text{Amount left with Harvey} = \$459 - \$200 -\$85 =\$174[/tex]
From the leftover money, Harvey deposits 2/3 of the amount leftover into a savings account. therefore, the amount in the saving account is,
[tex]\text{Amount in the saving account} = \dfrac23 \times (\text{Amount of money left})[/tex]
[tex]= \dfrac23 \times ($174)\\\\=\$116[/tex]
Now, the amount left for spending on entertainment is,
[tex]\text{Amount left for spending on entertainment} = \$174 - \$116 = \$58[/tex]
Hence, the money that Harvey has to spend on entertainment per week is $58.
