Answer:
21/8 or 2.625
Step-by-step explanation:
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.

Answer:
7/20 or 0.35
Answer:
3/4 - 2/5 = 7/20
Step-by-step explanation:
Rewriting the problem(fractions) you get 15/20 - 8/20.
And 15/20 - 8/20 = 7/20.

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]
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.

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Anna has a nickels and y dimes. She has at most 22 coins worth a minimum of $1.40 combined.
Let x be the number of nickels and y be the number of dimes. Then the equation is given as,
