Answers

Answer:

Step-by-step explanation:

the square means 90 add that to 25 and subtract from 180

Answer:

x = 65

Step-by-step explanation:

The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.

All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.

90 + x + 25 = 180

Subtract 90 and 25 from both sides.

90 + x + 25 - 90 - 25 = 180 - 90 - 25

x = 65

A bag contains 40 red and green marbles. The number of green marbles, g, is 9 times the number of red mapples, . How many red marbles are in the bag? O 4 O 6 O 34 O 36

Answers

Answer:

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).

Answers

Answer:

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Which of the following equations is equivalent to 3 • 12 = 36?
36 + 3 = 12
36 ÷ 3 = 12
36 • 3 = 12
36 – 3 = 12

Answers

Answer:

Step-by-step explanation:

36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.

36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
