Answer:X=15

Step-by-step explanation:

Combine the 5x and 9x then you move the 30 to the right side with 180 which gives you 14x=210 then you divide both sides.

Answer:

y = - 2x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, - 2)

m = [tex]\frac{-2-4}{5-2}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2, then

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2,  4)

4 = - 4 + c ⇒ c = 4 + 4 = 8

y = - 2x + 8 ← equation of line

Answer:

$5,000

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:

A = 2500(1 + (0.05 × 20)) = 5000

A = $5,000.00

Answer: 21 hours

Step-by-step explanation:

The lawn order can produce 10 landmowers in 7 hours.

This means that their speed is:

= 10/7

= 10/7 landmowers per hour

If they want to produce 30 lawnmowers, the amount of time they will take is:

= 30 ÷ 10/7 per hour

= 21 hours

Answer:

Call Brian's age: x, then Sushil's age is: x + 6 and Caroline's age is: x-5

So we have: x + (x + 6) + (x-5) = 64

=> 3x +1 = 64 => x = 63/3 = 21

the youngest of them: 21-5 = 16

Answer:

what most likely happen is water droplets will form on the outside of the glass, this is condensation.

Step-by-step explanation:

condensation means: Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.

Hope this helps, have a good day.

Answer:

60 70 80m9

Step-by-step explanation:

Answer:

-1

Step-by-step explanation:

2(.5n-3)=n-0.25(12-12n)

first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis

1n-6=n-3+3n

then you combine like terms and end up with

1n-6=-3+4n

add 6 to each side to get

n=3+4n

subtract 4n from each side to get

-3n=3

divide -3 from each side to get

n=-1

Answer:

D. 44 feet

Step-by-step explanation:

If her garden is square, that means that to find out the length of one wall we find the square root of 121. The square root of 121 is 11. Then because the garden needs 4 walls of fencing, we multiply 11x4=44.

Answer:

D) 44 feet

Step-by-step explanation:

As, the area of any square = Side x side

So here let's take side as "s"

So s x s = 121 square feet

S^2 = 121

So, s = the square root of 121

So, s = 11 cm

So the length of one side of the garden = 11 cm

So all the side are equal in a square

So, to fence we need to find the perimeter

Perimeter of square = 4s

= 4 x 11

= 44 feet

Hope it helps

Answer:

[tex](-4)^{10}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] , then

(- 4)[tex](-4)^{9}[/tex]

= [tex](-4)^{1}[/tex] × [tex](-4)^{9}[/tex]

= [tex](-4)^{(1+9)}[/tex]

= [tex](-4)^{10}[/tex]

Answer:

1/3

Step-by-step explanation:

Answer: The answer is [tex]\frac{1}{3}.[/tex]

Step-by-step explanation:

Step #1. Using with the unlike denominators, we find The Least Common Denominator: [tex]LCD= 15.[/tex]

Step #2. We multiply the numerators and the denominators in order to get The LCD in all the fraction denominators that looks in the equation like this: [tex]\frac{4*3}{5*3}+\frac{3}{15}-\frac{2*5}{3*5}.[/tex]

Step #3. Then we've begun rewriting the equation with the equivalent fractions that look in the equation like this: [tex]\frac{12}{15}+\frac{3}{15}-\frac{10}{15}.[/tex]

Step #4. Using with the like denominators we could also operate just only the numerators that look in the equation like this: [tex]\frac{12+3-10}{15}=\frac{5}{15}.[/tex]

The last but not least is step #5: We finally simplifying the equivalent fraction answer by 5 that look in the equation like this: 5÷5/15÷5=[tex]\frac{1}{3}.[/tex]

Answer:

Slope= -2

Step-by-step explanation:

start at the point (1,1) go up 2 and to the left one. That's a negative slope

Given :

The length of the rectangle, l = 8 cm/

The width of the rectangle, w = 75% of 8 cm

                                                 [tex]$= \frac{75}{100} \times 8$[/tex]

                                                 [tex]$=\frac{15}{20} \times 8$[/tex]

                                                 = 0.75 x 8

                                                 = 6

Therefore, the width of the rectangle is 6 cm.
