Choose the pair of numbers that is not a solution to the given equation.

Answer:

The pair (0,3) is not a solution to the equation

Step-by-step explanation:

This can be proved by simply replacing the x and y variables in the equation by the x and y values of the pair, and checking if the equation renders a true statement:

By replacing x and y with their values in the pair (0,3), that is x=0 and y=3, in the equation y = 5 - 2x  we get:

3 = 5 - 2 (0)

3 = 5 - 0

3 = 5

which is NOT a true statement.

On the other hand, the other two pairs (2,1) and (1,3) render true statements:

1 = 5 - 2 (2)

1 = 5 - 4

1 = 1

and

3 = 5 - 2 (1)

3 = 5 - 2

3 = 3

e-lub [12.9K]
You will choose 1 cheese 3 different ways because there are three types of cheeses.

You will choose your topings 6 different ways. 4!/(2!2!) = 4*3/2 = 6

Therefore you will be able to get 6 * 3 different pizzas = 18 pizza combinations.

To confirm the toppings, suppose they are (M)ushrooms (P)epperoni (O)nions and (B)acon

M P
M O
M B
P O
P B
O B

Total 6.The order doesn't matter here. M O is the same thing as OM

Noah drew 26 hearts, 21 stars, and 38 circles. what is the ratio of stars to hearts to circles?
mamaluj [8]

Answer:

21:26:38

Step-by-step explanation:

Ratio in mathematics is the relationship between two or more amounts, showing how many times they can be contained in one another.

Example: 1:2 means there are two times the first amount in the second.

For the case above;

Given;

Number of each shape noah drew;

hearts = 26

Stars = 21

circles = 38

The ratio of stars to hearts to circles

N(stars) : N(hearts) : N(circles)

21:26:38

Since they are not divisible by a common factor the ratio remains;

21:26:38

X-4=10;4x+1=57<br>i need to change the first equation into to the second equation.
cestrela7 [59]

Is this what you mean this is what i understood.



X-4=10;4x+1=57


First equation solve for x.

X-4=10

Add 4 both sides

X=10+4


X=14

Second equation substitute your x answer into second equation to make both sides equal.

4x+1=57

4(14)+1=57

56+1=57

57=57
