Byron is 2 years younger than Cindy. Eight
years ago, the sum of their ages was 14.
How old is Byron now?​

Answers

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

What is the answer to m / π = 7.3

Answers

Answer:

m=7.3π=22.93

Step-by-step explanation:

m=7.3π=22.93

(rounded to 2 decimal places)

Explanation:

Multiply both sides by π

mπ×π=7.3×π

m=7.3×π

m=7.3×3.14159....

m=22.9336....

For π, you can use your calculator value as I have done here, or you can use 3.14or3.142or227

Which equation represents a line which is parallel to the line 2y-5x=-162y−5x=−16?

Answers

Answer:

Step-by-step explanation:

For two lines to be parallel to each other, they must have the same slope.

The standard form of expressing equation of a line is y = mx+c

m is the slope.

First let us get the slope of the given line

Given the line 2y-5x = -16

Rerwrite in standard form;

2y-5x = -16

2y = 5x-16

Divide through by 2;

2y/2 = 5x/2 -16/2

y = 5x/2 - 8

The slope of the line is 5/2

Since we are not given options, we can as well say that the equation of the line parallel to this line must have a slope of 5/2 no matter the intercept. Example of such line are;

y = 5/2 x + 2

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?

Answers

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

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.

Answers

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

d Question 5 5. Given A is between Y and Z and YA = 14x, AZ = 10x and YZ = 12x + 48, find AZ
​

Answers

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
