Please help, solve for x

Answer:

-4x-7

Step-by-step explanation:

Answer:

x=32

Step-by-step explanation:

sum of interior angles of a triangle = 180

add up all angles and equate to 180

(4x-13)+(x+18)+15=180

5x=160

x=160/5=32

x+18  =   32+18    = 50

4x-13  =  4x32-13 = 128-13 = 115

add up all to check whether ans = 180;  15+50+115=180

step 1 solve for x step 2 after getting the value of x ,substitute and get the value of angles

x<=-8

(-∞, -8]

Answer:

$1300

Step-by-step explanation:

52/5 = 10.4

$125 * 10.4 = $1300

or another way

125/5 = $25/week

$25 week * 52 weeks = $1300

Answer:

The absolute value is the distance between the number and zero on a number line, while opposites are the same distance from the zero on the  number line, so they are also on opposite sides of 0.

Answer:

What is the symbol in this passage? In this passage, the symbol is Caesar's statue run with blood like a fountain while many Roman people were smiling and washing their hands in his blood. Her dream foreshadows a negative event and symbolizes Caesar's death.

Answer:

800

Step-by-step explanation:

Answer: 5cm and 8cm

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 26 ...... i

l × w = 40 ...... ii

We can reduce equation i to l + w = 13.

l + w = 13 ....... i

l × w = 40 ....... ii

From i, l = 13 - w ...... iii

Put the value of l into equation ii

l × w = 40

(13 - w) × w = 40

13w - w² = 40

13w - w² - 40 = 0

w² - 13w + 40 = 0

w² -8w -5w +40 = 0

w(w - 8) -5(w - 8) = 0

(w - 5) = 0 and (w - 8) = 0

w = 0 +5 and w = 0 + 8

w = 5

l = 8

The dimensions are 5cm and 8cm

Answer:

They sold 160 children's tickets.

Step-by-step explanation:

With the information provided, yoou can write the following equations:

x+y=233 (1)

8x+12y=2,156 (2), where:

x is the number of tickets for children 12 and under

y is the number of tickets for anyone over the age of 12

Now, you can solve for x in (1):

x=233-y (3)

Then, you have to replace (3) in (2) and solve for y:

8(233-y)+12y=2,156

1,864-8y+12y=2,156

4y=2,156-1,864

4y=292

y=292/4

y=73

Finally, you can replace the value of y in (3) to find x:

x=233-73

x=160

According to this, the answer is that they sold 160 children's tickets.

Answer:

well if we are going by pattern them possibly 20 or 30 im sorry if its wrong i just need more info on how i should answer it

Answer:

32

Step-by-step explanation:

To find the perimeter just add all of the sides together.

5+7+5+1+4+3+4+3=32

Answer:

d = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given

= 16(d + 1) = - 20 ← distribute parenthesis on left side

- 16d - 16 = - 20 ( add 16 to both sides )

- 16d = - 4 ( divide both sides by - 16 )

d = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

33%

Step-by-step explanation:

To start take the original price and divide it by the new sale price.  $1.20/$0.80 = 0.66666.  We can then round that answer to 0.67.  if the new price is 67% of the original price we must then we know that 67% minus the 100% will give us the discount.  100% - 67% = 33%

Answer = 33%

Answer:

i guess 3 23/49

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Since x=-2

-2+3y=4

Add 2 on both sides

3y=6

Divide 3 on both sides

y=2

Answer:

x is equal to -2

the equation is x + 3y = 4

so we substitute the value of 'x' which is -2 in equation x + 3 = 4

Step-by-step explanation:

then we move 3y on left side.

then we add 4 + 2 which is 6.

then it will be, y = 6/3

which is 2

therefore we get y = 2

hope this helps you ☺️☺️

Answer:

I will let you answer this after reading below

Step-by-step explanation:

a=area

[tex] a = \pi {r}^{2} [/tex]

[tex]r = d \div 2[/tex]

write a in terms of d

[tex] a = \frac{\pi {d}^{2}}{ 4}[/tex]

since it's a semicircle divide a by 2 and that's your answer
