Tom has t dollars. He buys 5 packets of gum worth d dollars each. How much money does he have left?
Answer: t - 5d
Step-by-step explanation: Since you are buying 5 and they cost d dollars you would multiply 5 by d. Then since you have t dollars as a total you subtract 5d from t so you get t -5d.

d Question 5 5. Given A is between Y and Z and YA = 14x, AZ = 10x and YZ = 12x + 48, find AZ
Answer:
Step-by-step explanation:
If A is in between Y and Z, then;
YA+AZ = YZ
Given.
YA = 14x,
AZ = 10x and
YZ = 12x + 48
Substitute into the formula
14x+10x = 12x+48
Find x;
24x = 12x+48
24x-12x = 48
12x = 48
x = 48/12
x = 4
Get AZ
AZ = 10x
AZ =10(4)
AZ = 40

Answer:
150 cubic centimeters
Step-by-step explanation:
1/6×X+95=4/5×X
Subtract X from both sides of the equation
Multiply/Combine like terms
95=19/30×X
Multiply by 30/19 and simply
30/19*95=X
Solve for X to get 150
1/6×150=25
4/5×150=120
Answer:
150 cubic centimeters
Step-by-step explanation:
1/6*x+95=4/5*x
Move stuff around
95=1/6+4/5*x
Multiply/Combine like terms
95=19/30*x
Multiply by 30/19 and then simplify
30/19*95=x
Solve for x
1/6*150=25
4/5*150=120

7. The vertices of a triangle are P(-7, -1). Q(-7, -8), and R(3. -3). Name the vertices of the
image reflected across the line y=x.
OPX4,7). Q18. 7), R3.-3)
OP/4.-7). Q18. -7). R33)
OP(-7). QI-S.-7), R(-3.3)
OPT+7). Q1-8. 7). R(-3, -3)
The vertices of the image triangle reflected across the line y = x are P'( -1, -7), Q'( -8, -7), and R'( -3, 3).
Therefore, the correct answer is:
P'( -1, -7), Q'( -8, -7), R'( -3, 3)
Here,
To find the image of the triangle vertices reflected across the line y = x, we need to swap the x-coordinates with the y-coordinates.
Original vertices of the triangle:
P(-7, -1)
Q(-7, -8)
R(3, -3)
Now, swap the x and y coordinates to get the reflected image:
Reflected image vertices:
P'( -1, -7)
Q'( -8, -7)
R'( -3, 3)
So, the vertices of the image triangle reflected across the line y = x are P'( -1, -7), Q'( -8, -7), and R'( -3, 3).
Therefore, the correct answer is:
P'( -1, -7), Q'( -8, -7), R'( -3, 3).

j
— + 7 = -12
-2
what is the answer
Answer:
j=38
Step-by-step explanation:
j
— + 7 = -12
-2
move the (7) to the other side by subtracting,
-12-7= 19
j
— = -19
-2
continue by moving (-2) to the other side as well, do so by multiplying,
-19*-2= 38
therefore, j=38
The store bought the bike at a wholesale price. The bike store marked up the wholesale cost of the bike by 60%. What was the wholesale cost of the bike if the store sold the bike to Andre for $160?
Answer: The wholesale cost of the bike = $100
Step-by-step explanation:
Let x = wholesale cost of the bike
As per given,
Selling price = cost price + (Mark up percent) x ( cost price) (i)
Selling price of bike = $160
Mark up percent = 60% =0.60
Substitute values in (i) , we get
[tex]160= x+0.6x\\\\\Rightarrow\ 160=1.6x\\\\\Rightarrow\ x=\dfrac{160}{1.6}\\\\\Rightarrow\ x= 100[/tex]
Hence, the wholesale cost of the bike = $100
If the mean of 20 prices is $10.39, and 5 of the items with a mean of $10.99 are sampled, what is the mean of the other 15 prices?
Answer:
$10.19
Step-by-step explanation:
We are told:
If the mean of 20 prices is $10.39
We have to find the total price
= Mean × number of prices
= 20 × $10.39
= $207.8
5 of the items with a mean of $10.99 are sampled
We would also find the total price
Mean × Number of samples
$10.99 × 5
= $54.95
what is the mean of the other 15 prices?
We find the total prices of the 15 prices
= Total 20 prices - Total of 5 prices
= $207.8 - $54.95
= $152.85
The mean of the other 15 prices
= $152.85/15
= $10.19
A 2 yard piece of ribbon costs $10.80. What is the price per inch?
Answer:
0.15
Step-by-step explanation:
2 yards = 72
10.80 / 72 = 0.15
1 yard is 36 inches. 2 yards is 72 inches. The question wants you to divide $10.80 into the inches that represent the yards. $10.80 / 72 = $0.15

years ago, the sum of their ages was 14.
How old is Byron now?
Step-by-step explanation:
let age of Byron be b yr old and Cindy be c yr old.
c = b + 2 --(1)
b - 8 + c - 8 = 14
b + c = 30 --(2)
sub (1) into (2):
2b = 28
b = 14
therefore Byron is 14 yr old now.

Step-by-step explanation:
Byron is 2 yrs younger than Cindy. 8 years ago the sum of their ages was 14.
Byron is 2 years at that time. Definitely, Cindy is 12 years old so the sum of their ages was 14. Let us just add 8 years to Byron's age at that time so 2 + 8 = 10

The weekly salaries of teachers in one state are normally distributed with a mean of $490 and a standard deviation of $45. What is the probability that a randomly selected teacher earns more than $460 a week?
Answer:
0.74751
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ, where
x is the raw score = $460
μ is the population mean = $490
σ is the population standard deviation = $45
z = 460 - 490/45
z = -0.66667
Probability value from Z-Table:
P(x < 460) = 0.25249
P(x > 460) = 1 - P(x<460)
P(x > 460) = 1 - 0.25249
P(x > 460) = 0.74751
The probability that a randomly selected teacher earns more than $460 a week is 0.74751

Mrs. Thompson wants to buy centerpieces to use at a party. It will cost $49 to have the centerpieces delivered plus $0.89 per centerpiece.
Part A
Let c be the number of centerpieces that Mrs. Thompson purchases. Choose the expression that shows the amount of money she will pay altogether for each centerpiece.
49c + 0.89
0.89 + c + 49
c(0.89 + 49)
49 + 0.89c
Part B
Evaluate the expression to find out how much Mrs. Thompson will pay if she orders 400 centerpieces.
Enter your answer in the box.
Answer:
a. 49 + 0.89c
b. $400
Step-by-step explanation:
Given
Delivery = $49
Cost per Centrepiece = $0.89
Solving (a): Expression that represents the equation.
From the question, we have that the number of centrepiece is represented by c
The expression can be gotten by the following formula.
Cost of Delivery + Cost per centrepiece * Number of centrepieces
This gives
49 + 0.89 * c
49 + 0.89c
Hence, the expression that represents the scenario is 49 + 0.89c
Solving (b): Payment for 400 centrepieces
To solve this, we simply substitute 400 for c in the expression in (a)
This gives:
Payment = 49 + 0.89 * 400
Payment = 49 + 356
Payment = 405
Hence, Mrs. Thompson will pay $405 for 400 centerpieces
