Answer:

-3/2

Step-by-step explanation:

First, take the brackets out:

-5/6 -2/3

Second, make the denominator the same using the GCF:

The GCF of 3 and 6 is 6.

Third, find an equivalent fraction of -2/3 that has a denominator of 6.

This is -4/6.

Finally, find your sum.

-5/6 -4/6=-9/6

Make sure to simplify!

-9/6=-3/2

George and Riley are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges.

worty [1.4K]

The cost of small box of oranges is $7.

The cost of large box of oranges is $13.

Step-by-step explanation:

It is given that,

3 small boxes of oranges and 14 large boxes of oranges for a total of $203.

11 small boxes of oranges and 11 large boxes of oranges for a total of $220.

Let us take,

The cost of small box of oranges = x
The cost of large box of oranges = y

The system of equations are framed as :

3x + 14y = 203 ---------(1)

11x + 11y = 220 ---------(2)

To solve these equations for x and y values :

Multiply equation (1) by 11 and equation (2) by 3

Subtract eq(2) from eq(1),

33x + 154y = 2233

- (33x + 33y = 660)

121 y = 1573

⇒ y = 1573 / 121

⇒ y = 13

∴ The cost of large box of oranges is $13.

Substitute y=13 in the eq(1),

⇒ 3x + 14(13) = 203

⇒ 3x + 182 = 203

⇒ 3x = 203 - 182

⇒ 3x = 21

⇒ x = 21 / 3

⇒ x = 7

∴ The cost of small box of oranges is $7.

Solve for the variable shown. Round answers to the nearest hundredth if needed.

Olenka [21]

Answer and Step-by-step explanation:

Question 4:

We need to solve for y, so we need to use the cosine trig function, which is adjacent divided by hypotenuse.

$cos(21) = \frac{y}{18}\\\\18(cos(21)) = y = 16.8\\\\\\$

Question 5:

We need to use the sine trig function, which is opposite divided by hypotenuse.

$sin(43) = \frac{31}{x} \\\\x = \frac{31}{sin(43)} = 45.45$

What line is perpendicular to y= 7/8x-2

belka [17]

The slope for a line that's perpenficular is the resepical of each other
Ex. Slope: -2 Perpendicular Slope to 1st Line: \frac{1}{2}
so the perpendicular slope to 7/8 is -8/7
for y-intersecpt i would go on desmos(graping calculator website) and type in the equation y=-8/7x+b
Use the slider, and it you give you... You can't find the whole equation (y=mx+b). Because as long as the line has the slope of -8/7 it's perpenicular.
Did the problem tell you anything about a point that this new line goes through? Or no?
