Answer:

2 loaves of bread

Step-by-step explanation:

The equation becomes

3b + 18 = 24 (because they said 18 rolls were sold)

you would subtract 18 from both sides to get 3b = 6

divide both sides by 3 and you get b = 2

Answer:

Okay, let's get into the formula:

5 ⅔ + c = 10

( pindah ruas )

c. = 10 - 5 ⅔

c= 13/3

c = 4 ⅓

So, the number of punch cups added to the bowl is 4 ⅓ cups

Answer:

teo= 15 years old

richard= 27 years old

Step-by-step explanation:

richard=r

teo=t

r + t=42

t + 12= r

u can use substitution here  

(t+12) + t=42

2t + 12= 42

2t=30

t= 15

to find r, you just do 15 + 12= 27

to check you can do 27 + 15= 42

The age of Richard and Teo will be 27 years and 15 years, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Richard and Teo are 42 years old. Richard is 12 years older than Teo.

Let x be the age of Richard and y be the age of Teo. Then the equation is given as,

x + y = 42         ...1

x = y + 12         ...2

From equations 1 and 2, then we have

y + 12 + y = 42

2y = 30

y = 15

Then the value of the variable 'x' is given as,

x = 15 + 12

x = 27

The age of Richard and Teo will be 27 years and 15 years, respectively.

Answer/Step-by-step explanation:

There are 81 Alligators.

The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.

45 ÷ 5 = 9

9 x 9 = 81

5:9 x 9 = 45:81

Answer:

Step-by-step explanation: number 1 is x <-15 because first simplify both sides of equation -1/5 x > 3 then multiple both sides by 5/(-1) (5/-1) x (-1x5) > (5/-1) x (3) which x < -15

Answer:

31.8

Step-by-step explanation:

Answer:

Enrique spent D. $31.80 on soda.

Answer:he usual assumption is that there is a 50% chance of heads on each toss of each coin. So, the chances of getting at least two heads when tossing three coins at the same time is 4/8 (Because all the 8 possibilities are equally likely) 50 percent.

Step-by-step explanation:

Answer:

10%

Step-by-step explanation:

Price of computer = $750

Amount of sales tax = $75

Sales tax rate = Amount of sales tax / Price of computer × 100

= $75 / $750 × 100

= 0.1 × 100

= 10%

Sales tax rate = 10%

Sales tax rate = 10% of selling price

Answer:

C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2

Step-by-step explanation:

Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.

A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:

- If there are different y values for the same x value

- If the points in order do not create a straight line

- If the points in order do not have a repeating pattern

To identify a function, look for:

- Straight lines

- An actual written function (such as "y =" or "f(x) =")

- A pattern on a table

Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.

Here's an example of a table that represents y as a function of x:

- X: 1  2  3  4  5  

- Y: 3  5  7  9  11

- Pattern: +2 y for every x with constant 1

- X: 3  1   5    4   7  

- Y: 9  3  15  12  21

- Pattern: +3 y for every x with constant 0

Here's an example of a table that doesn't represent y as a function of x:

- X: 1  2  3  4  5  

- Y: 2  5  8  2  4

- Pattern: None

- X: 3 1 5 1 7  

- Y: 1 7 8 9 4

- Pattern: None

Answer: It will take 15 weeks for Cyndi and her sister to have the same amount of money.

Step-by-step explanation:

Given: Cyndi has $55. Her sister has $115.

Cyndi saves $10 per week. Her sister saves $6 per week.

Let x= Number of weeks.

Total amount of money Cyndi has = 55+10x            (i)

Total amount of money sister has = 115+6x              (ii)

From (i) and (ii) , we get

[tex]55+10x=115+6x\\\\\Rightarrow\ 10x-6x=115-55\\\\\Rightarrow\ 4x=60\\\\\Rightarrow\ x=\dfrac{60}{4}\\\\\Rightarrow\ x=15[/tex]

Hence, it will take 15 weeks for Cyndi and her sister to have the same amount of money.

Answer:

When f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.

Step-by-step explanation:

In other words, the rule is:

Given the function

[tex]f(x)=x[/tex]

Thus, when f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.

In the graph, the red line is representing the parent function f(x) and the blue line is representing the effect on the graph i.e. f(x+5).

Answer:

Step-by-step explanation:

The markup would be 37.5%. 80-50 = 30. If you set up the  

proportion, is/of = %/100, it would be 30/80 = %/100. Multiply  

30*100. = 3,000. Divide this by 80 and you get 37.5.
