Mrs. Coners grades 120 math tests in 3
hours. Mrs. Bing grades 100 math tests in
2 hours. Who grades math tests at a
quicker rate?
Answer: The answer is Mrs. Coners.
Explain: It is Mrs. Coners because she graded 60 math test pages 2 hours,
it would be 40 math test pages per 1 hour each. <-- (3 hours)
Mrs. Bing graded 50 math test pages 1 hour each. 50 times 2 = 100.
Therefore, your answer is Mrs. Coners.

What is m∠PQR?
The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x + 5) degree and angle SQR is (x + 3) degree.
Answer: m∠PQR = 134°
Step-by-step explanation:
Given: PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.
That means ∠PQR and ∠SQR are linear pair [Linear pair is a pair of two angles made on one line and their sum is 180°]
⇒ ∠PQR + ∠SQR = 180° (i)
Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)° [given]
Put this in (i), we get
(3x + 5)° + (x + 3)° = 180°
⇒ 3x + 5 + x + 3 = 180
⇒ 4 x + 8 = 180
⇒ 4 x = 180-8
⇒ 4 x = 172
Divide both sides by 4
⇒ x= 43
So, ∠PQR= (3(43) + 5)° = 134°
Hence, m∠PQR = 134°
The measure of m ∠PQR is 134 degrees.
GivenPS is a line segment.
Q is the point between segment PS.
QR is another line segment that passes through segment PS.
Which property of the triangle is used to solve the value of x?The sum of two angles made on one line is equal to 180 degrees.
[tex]\angle \rm PQR + \angle SQR = 180[/tex]
Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.
Substitute all the values in the equation
[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]
The value of x is 43 degrees.
Therefore,
The measure of m ∠PQR is;
[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]
Hence, the measure of m ∠PQR is 134 degrees.

A jewelry artist is selling necklaces at an art fair. It costs $105 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $12 each.
The inequality 12n > 105 + 4.50n represents the situation in which the artist makes a
profit.
A)Will the artist make profit if she sells 15 necklaces? Show how you know.
B) explain or show your reasoning
Answer:
They will break even... but im not 100% sure im correct
Step-by-step explanation:
Im not 100% sure but here is what i have...
based on the given inequality the new one would be 15n>105+4.50n,
First subtract the 4.50n from the right side of the inequlaity sign.
Now you should have 10.5n>105
second, plug in a random number to see if she will make money or not..
I used 10, so plug 10 in for "N".
it will look like this, 10.5(10)>105
now do the math and get, 105>105,
which brings me to the cunclution she breaks even..

You have $121 in a savings account and save $1 2
per week. Your friend has S9 I in a savings
account and saves SI 7 per week. How many
weeks will it take for you and your friend to have
the same balance?
It will take 6 weeks for you and your friend to have the same balance.
First, you must set up your equation, with [tex]x[/tex] representing the amount of weeks
until you and your friend have the same balance.
[tex]121+12x=91+17x[/tex]
Then, you must subtract 91 on both sides.
[tex]30+12x=17x[/tex]
Next, subtract 12x on both sides.
[tex]30=5x[/tex]
Finally, divide 5 on each side
[tex]x=6[/tex]
