Step-by-step explanation:

I believe I am right. I hope this helps you :)

Answer:

all real numbers

Step-by-step explanation:

7(x + 2) - 10 = 7x + 4

7x + 14 - 10 = 7x + 4

7x + 4 = 7x + 4

4 = 4

the answer is all real numbers because 4 will always equal 4

Answer:

Step-by-step explanation:

Just type 10% into the calculator and it will automatically say

" 10% of " then you can type in any number you want to be

ten percent of!

Answer: you would do 10 over 100 and equal it to the number u want to find over the number of full amount of what u want.

Step-by-step explanation:

10/100 = x/25 and than you’d cross multiply . And than set x to one side by itself to find what x equals and that should be ur answer

Answer:

- 3x - 6y

Step-by-step explanation:

Given

(x + 2y)(- 3) ← multiply each term in the parenthesis by - 3

= - 3x - 6y

Answer:

13

Step-by-step explanation:

This one sounds really hard, but its actually really easy once you think about it.

The problem states that both y coordinate are 13, but have different x coordinates. It asks for the sum of the slope and the y intercept. The y intercept will always have 0 as x.

To find a slope, the equation is y2-y1/x2-x1. In this case, we don't actually know what x is. But we do know what y is:

13-13/x2-x1

0/x2-x1

0

So the slope is 0.

Since we know that the y intercept has to have 0 as x, we don't actually need to know what x is.  

So the y intercept is 13.

13+0=13.

Answer:

Brody purchased 16 songs.

Step-by-step explanation:

Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3

[tex]\frac{B}{J}=\frac{2}{3}[/tex] ------(1)

Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5

[tex]\frac{J}{S}=\frac{4}{5}[/tex] -------(2)

If Sadie bought the songs (S) = 30

From equation (2),

[tex]\frac{J}{30}=\frac{4}{5}[/tex]

J = [tex]\frac{4\times 30}{5}[/tex]

J = 24

By substituting the value J = 24 in equation (1),

[tex]\frac{B}{24}= \frac{2}{3}[/tex]

B = [tex]\frac{2\times 24}{3}[/tex]

B = 16

Therefore, number of songs purchased by Brody = 16.

Answer:

rate of change: -3000 feet per minute

the rate of change is showing how many feet the plane descents each minute

Answer: -24

Step-by-step explanation: Convert the decimal into a fraction. Use -a/b=a/-b=-a/-b, to rewrite the fraction. Simplfy the complex fraction. Multiply both sides of the equation by 6. Move constant to the right-hand side and change its sign. Add the numbers Divide both side of the equation by -5 and you get -24.

Answer:

1. -1

2. 25°

3. 26 1/4

Step-by-step explanation:

1. 14-8 is 6, -2 - 4 = -6, 6 ÷ -6 is -1

2. 75 + 80 = 155, 180 - 155 = 25°

3. cross multiply 4/5 = 21/x  (4x= 105) = 26 1/4 or 105/4

Answer:

6/35

Step-by-step explanation:

-4/5 - ( - 2/5 ) + 4/7

-4/5 - ( - 2/5 ) + 4/7

-4/5 - [tex]\frac{-2}{5}[/tex]+ 4/7

[tex]\frac{-2}{5}[/tex] + 4/7

6/35

Answer:

If the side which lies on one ray of the angle is longer than the other side, and the other side is greater than the minimum distance needed to create a triangle, the two triangles will not necessarily be congruent. to "swing" to either side of point G, creating two non-congruent triangles using SSA.

Hope this helped, Have an amazing day!!

Answer:

Expressing a number in a power of 2 means that you have to figure out how many times you should multiply 2 by itself so the product will be that number.

The number is expressed as 2^n

For example:

Express 16 as a power of 2:

To get 16, you have to multiply 2 by 4 times.

2 × 2 × 2 × 2 = 16

16 = 2^4

Then the answer is 2^4

Given that the wolf would eat the goat, the goat would eat the cabbage but the wolf wouldn't eat the cabbage.

So, leave the wolf and cabbage behind (at side 1) and take the goat to the other side (side 2) of the river.

Then, come back with the empty boat from side 2 to side 1.

Take the wolf (or the cabbage) from side 1 to side 2 of the river.

Now, observe that, the goat is already on side 2, and the wolf and the goat can't be on the same side as the wolf would eat the goat, So, leave the wolf on side 2 and come back with the goat from side 2 to side 1.

Leave the goat on side 1 and take the cabbage from side 1 to side 2.

Now, come back with the empty boat from side 2 to side 1 and take the goat from side 1 to side 2.

In this way, the farmer can carry himself and his purchase to the other side of the river.

Step-by-step explanation:

Answer:

fourty five

Step-by-step explanation:

Sum of two angles that are supplementary = 180°

Let the first angle be x .

Then the other angle = x + 40

Measure of each angle =

[tex]x + x + 40 = 180[/tex]

[tex]2x + 40 = 180[/tex]

[tex]2x = 180 - 40[/tex]

[tex]2x = 140°[/tex]

[tex]x = \frac{140}{2} [/tex]

[tex]x = 70°[/tex]

Which means :-

The first angle:-

[tex]= x = 70°[/tex]

The second angle :-

[tex]x + 40[/tex]

[tex]70 + 40[/tex]

[tex] = 110°[/tex]

Therefore , the two supplementary angles are 70° and 110° .
