Answer:

x= -34/3

Step-by-step explanation:

just solve by multiplying both sides by 15, then distribute 10 and 3 through the parenthesis, multiply both sides by 2, move the variable to the left side and change the sign, move the constant and change the sign, combine like terms, calculate the sum, and finally divide both sides by -3

The sum of two numbers is 13. Two times the first number minus three times the second number is 1. If you let x stand forbthe fi

Zina [86]

X + y = 13......x = 13 - y
2x - 3y = 1

2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5

x + y = 13
x + 5 = 13
x = 13 - 5
x = 8

so, x = 8 and y = 5

The lines shown below are parallel. If the green line has a slope of -3/7, what is

BartSMP [9]

Answer: the slope of green line = $-\frac37$

Step-by-step explanation:

We know that,

If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.

Given: The red line and the green line are parallel.

The slope of red line = $-\frac37$

Then, the slope of green line = $-\frac37$ [Slopes of two parallel lines are equal]

Hence, the slope of green line = $-\frac37$

Find the ratio of the trig function indicated.

Andrew [12]

Answer:

$\huge\boxed{\bf\:Ratio = 4:5}$

Step-by-step explanation:

We have a right angled triangle given.

At first, let's note that, sin θ = oppposite side of the triangle / hypotenuse of the triangle.

Now, in the given triangle, from the view of ∠θ,

Opposite side of the triangle = 8
Hypotenuse = 10

Then,

$\sin \theta = \mathrm{\frac{opposite \: side}{hypotenuse}}\\\sin\theta = \frac{8}{10}\\\sin\theta = \frac{4}{5}\\\\\\\Longrightarrow \boxed{\mathrm{Ratio = 4:5}}$

It costs $350 to carpet an 8 ft by 10 ft room. At this rate, how many dollars would it cost to put the same carpeting in a 24 ft

Vlad [161]

Answer:

$3,150

Step-by-step explanation:

You have to divide the price by square ft. Then you divide $350 by 80 and you get 4.375. You then multiply 24 by 30 and you get 720. After you multiply 4.375 by 720 and you get your answer
