Answers

To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157

X= 23

Given segment AC and point B that lies on AC, if AB = 9 and BC= 49, find AC

Answers

Answer:

58

Step-by-step explanation:

Let's draw this out (see attachment).

We know that since B lies on AC, we have the points in order from left to right: A, B, C.

AB = 9, which is the left portion. BC = 49, which is the right portion. Then AC is simply the sum:

AC = AB + BC = 9 + 49 = 58

The answer is thus 58.

Point Fis on line segment EG . Given FG = 4 and EF = 9 determine the length EG

Answers

Answer:

EG is 13.

Step-by-step explanation:

So we have a line segment EG.

Point F is somewhere on EG.

And we are given that FG is 4 and EF is 9.

Therefore, the length of EG will be the combined lengths of FG and EF. In other words:

[tex]EG=EF+FG[/tex]

Substitute 9 for EF and 4 for FG. Thus: "

[tex]EG=9+4[/tex]

Add:

[tex]EG=13[/tex]

So, the length is EG is 13.

m = 14

180 - p = 116

180 - 116 = p <- as you noticed, the negative sign changed to a positive one, cuz p moved to the other side of the equal sign.

64 = p

n + 86 = 118

n = 118 - 86

What number when increased by 15% becomes 299 Please help willl mark brainest!

Answers

Let's make an equation with the information given.

A 15% increase in a number means that the number was multiplied by 1.15.

[tex]1.15x=299[/tex]

[tex]x=260[/tex]

Hope this helps.

頑張って!

Answer:

260

Step-by-step explanation:

Let's call the number x.

When x is increased by 15% it is equal to 299. The number itself is 100%, so we should multiply x by 115%. Convert 115% to a decimal. Divide 115 by 100 or move the decimal place two spots to the right.

115/100= 1.15                                 or                        115.0 --> 11.5 --> 1.15

When x and 1.15 are multiplied they should equal 229. Set up an equation.

1.15x=229

We want to solve for x. Therefore, we must isolate x on one side of the equation. x is being multiplied by 1.15 The inverse of multiplication is division. Divide both sides of the equation by 1.15

1.15x/1.15=229/1.15

x=229/1.15

x=260

When 260 is increased by 15% the result is 299.

if y= 1/5 when x=3, find y when x=4, given that y varies directly with x

Answers

Answer:

[tex]y = \frac{4}{15} [/tex]

Step-by-step explanation:

To find y when x=4, we must first find the relationship between them

The statement

y varies directly with x is written as

[tex]y \: \: \: \alpha \: \: \: kx[/tex]

where k is the constant of proportionality

From the question

when y = 1/5

x = 3

Substitute the values into the above formula and solve

That's

[tex] \frac{1}{5} = 3k \\ 15k = 1 \\ k = \frac{1}{15} [/tex]

So the formula for the variation is

[tex]y = \frac{x}{15} [/tex]

From the question

when x = 4

[tex]y = \frac{4}{15} [/tex]

To simplify this expression, we combine all the like terms. We cannot solve for x because there is no equal sign and/or no value for x.

Equation: (10x² - 10x - 6) + (x + 6)

[tex]\bf Step~1:[/tex]

-10x and x are like terms. Remember: there is an invisible 1 behind the variable x. We add these like normal numbers.

[tex]\bf -10x+1x=-9x[/tex]

[tex]\bf Step~2:[/tex]

-6 and 6 are also like terms. Again, we add them as written.

[tex]\bf -6+6=0[/tex]

Since our answer is 0, we do not have to write it in our simplified expression.

[tex]\bf Step~3:[/tex]

Now, let's add the terms together. Since 10x² doesn't have any like terms, we just let it be. We take our previous number, -9x, and we add it to 10x².

Answer:

I feel like its that but im rlly not sure.

Step-by-step explanation:

Leanne's list is incorrect and  there are 3 different sides a person can choose. So, there are a total of 6 possible ways a person could choose their dinner.

How to determine the number of combinations?

The given parameters are:

Main Dish: B, C and P

Sides: A and F

Using the above parameters, the combination of dishes are:

BA, BF, CA, CF, PA and PF

Hence, we can conclude that Leanne list is incorrect

Also, we have:

Dish = 3

Sides = 2

So, the number of dinner to choose is:

Dinner = 3 * 2 = 6

Hence, a person could choose their dinner in 6 ways
