2.Susan and Tom want to know the combined amount of money they earned last week. They both earned $9 per hour, but Susan also earned a $45 bonus. Susan added her earnings to Tom's earnings to write the expression (9S + 45) + 9T, where S is the number of hours she worked, and Tis the number of hours Tom worked. Tom added their combined hourly wages to Susan's bonus to write the expression 9(S + T) + 45. Which of the following statements is true?
A.They are both correct, and their expressions are equivalent.
B.They are both correct, and their expressions are not equivalent.
C.Only one of them is correct, and their expressions are equivalent.
D Only one of them is correct, and their expressions are not equivalent.
3. Amanda and Trinity each wrote an expression, but only Amanda's expression is equivalent to 2x + 5. What could be Trinity's expression?
A.2(x+3)-1
B.3x-(x-5)
C.5(x+1)-3x
D.5x-3(x-1)
Answer:
1. B, 2. A, 3. DStep-by-step explanation:
Question 1One off fee: $5Each ride: $0.90Number of rides: rTotal payment:
3(5 + 0.9r)Correct choice is B
Question 2Since
9S + 45 + 9T = 9S + 9T + 45 = 9(S + T) + 45, the expressions are equivalent and therefore both Susan and Tom are correctThe true statement is A
Question 3Let's compare the expressions with Amanda's expression
A. 2(x + 3) - 1 = 2x + 6 - 1 = 2x + 5, equivalentB. 3x - (x - 5) = 3x - x + 5 = 2x + 5, equivalentC. 5(x + 1) - 3x = 5x + 5 - 3x = 2x + 5, equivalentD. 5x - 3(x - 1) = 5x - 3x + 3 = 2x + 3, not equivalent so this is Trinity's expressionWhat is the coefficient of the third term in this expression?
5b³ - 10 + 4c³?
Answer:
4
Step-by-step explanation:
A coefficient is a number before the variable. The third term is 4c^3, and the coefficient is 4.

-4(y-2)=12 help please
Answer:
-2
Step-by-step explanation:
(y-2)=-(12/4)
y-2= -4
y= -4+2
y = -2
Answer:
y = -1
Step-by-step explanation:
1. -4(y - 2) = 12
2. -4y + 8 = 12
3. -4y + 8 = 12 - 8
4. -4y = 4
5. -4y/-4 = 4/-4
6. y = -1
Check your answer:
-4(y - 2) = 12
-4(-1 - 2) = 12
4 + 8 = 12 True

A triangle has sides with lengths 8, 15, and 17.
Approximate the acute angles in this triangle.
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the acute angle of the given triangle is 28.07 degrees.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A triangle has sides with lengths 8, 15, and 17.
By Pythagoras theorem, we have
H² = P² + B²
17² = 8² + 15²
289 = 64 + 225
289 = 289
The dimension of the triangle satisfies the Pythagoras theorem. Hence the triangle is a right-angle triangle.
Then the acute angle will be
[tex]\rm \theta =Sin ^{-1} \dfrac{8}{17}\\\\\theta = 28.07^o[/tex]
Thus, the acute angle of the given triangle is 28.07 degrees.

Jo works in a cafe she sells cups of tea and cups of coffee in the ratio 1:3 on Monday jo sold a total of 244 cups of coffee.
Jo thinks she must have sold more than 200 cups of coffee. Is jo correct?
Answer:
No, the thought is wrong
Step-by-step explanation:
Here, we want to check if Jo is correct
The ratio we have is tea cups to coffee cups of ratio 1:3
Now, there are 244 cups of coffee
Now let’s say the total number of cups is x
For the ratio to be correct
Then;
3/4 * x = 244
x = (244*4)/3
x = 325
Now let’s subtract the number of cups
That will be;
325 - 244 = 81
This means the number of cups she thought was incorrect
The perimeter of a square is 48 inches. What is the area, in square inches, of the square?
Answer:
the area is 144
Step-by-step explanation:
48 ÷ 4 (which is how many sides a square has) is 12
SO 12 × 12 bc l×w and all sides of a square are equal
the answer is 144
Two families went to the event. The first family bought two children's tickets and one adult ticket and paid a total of 8.2 euros. The other family bought three children's tickets and two adult tickets and paid a total of 14.1 euros. Can you tell me how much one child costs and how much one adult ticket costs?
Answer:
Step-by-step explanation:
step a system of two equations c = child ticket a = adult ticket
eq 1) 2c + 1a = 8.2 multiply by 2
eq 2) 3c + 2a = 14.1
I will multiply eq 1 times TWO and subtract eq 2 from eq 1a)
eq 1a) 4c + 2a = 16.4
eq 2) 3c + 2a = 14.1
subtract (4c - 3c) + (2a -2a) = 16.4 - 14.1
c + 0 = 2.3 euros for one child ticket
Now find the adult ticket price, plug 2.3 for c into eq 1)
eq 1) 2c + 1a = 8.2
eq 1) 2(2.3) + 1a = 8.2 solve for a
4.6 + a = 8.2 substract 4.6 from both sides
a = 8.2 - 4.6
= 3.6 euros for one adult ticket
double check using eq 2) we know c and a values
eq 2) 3c + 2a = 14.1
eq 2) 3(2.3) + 2(3.6) = 14.1
6.9 + 7.2 = 14.1
14.1 = 14.1

You told your friend that you could eat 5/8 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?
Answer:
5/16
Step-by-step explanation:
Given that:
Fraction of claim = 5/8
Amount actually eaten = 1/2 of claim
Amount actually eaten = 1/2 * 5/8 = 5/16
Fraction of large pizza actually eaten is 5 /16
Hence, he ate, 5/16 of large pizza

Answer:
x = 30, y = 6
Step-by-step explanation:
Here, we want to use the property of parallelograms
mathematically, the lengths of the parallel sides are equal
This mean:

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?
A.72.75
B.76
C.89.5
D.97
Pls help TT
Answer:
total points on the 4 tests- 94x4= 376
376- 85= 291
291/3= D. 97
Answer:
D. 97
Step-by-step explanation:
x = sum of 4 test grades Jared received
[tex]\frac{x}{4} = 94[/tex]
x = 376
If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:
x - 85 --> 376 - 85
= 291
Now that one of his test grades are not considered, this means there are only 3 test grades to consider.
291 must be divided by 3 to get the average:
[tex]\frac{291}{3}[/tex] = 97
The answer is D) 97
