15q – 4r = 62
5q + 8r = 86

Answers

Answer 1

q= 6

r= 7

work--

Multiply 1st column by -2:

-30q+8r=-124

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124

Solve for r:

r=7

Step-by-step explanation:

you do x^5 = X x X x X x X x X and x^2 is X x X so X^5 x X^2 is X x X x X x X x X x X x X which can be simplified to X^7

and the same for y

y^4 = Y x Y x Y x Y and y^2 is Y x Y, so Y^4 x Y^2 = Y x Y x Y x Y x Y x Y  which simplifies to Y^6

Set up a proportion.

The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.

Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.

So 18/45 = 10/x

Reduce 2/5 = 10/x

Cross multiply 2x = 50

Solve x = 25

Of the numbers 5, 6, or 7, which is a solution of the inequality y + 4 < 10?

Answers

ExplanationGiven 5,6 and 7 part of the y-term.

[tex] \begin{cases}5 \in y \\ 6 \in y \\ 7 \in y \end{cases}[/tex]

Solve the Inequality.

[tex]y + 4 < 10 \\ y < 10 - 4 \\ y < 6[/tex]

Therefore, the value of y is lesser than 6. That meane it can't be y = 6 or greater. Hence, 5 is the solution to the Inequality.

Answer

y = 5 is the solution to the Inequality.

But if you want to solve for Inequality only then it is y < 6

Arnie is mixing red and yellow paints to make two different shades of orange. To make 1 cup of dark orange​ paint, he needs 7 ounces of red paint and 1 ounce of yellow paint. To make 2 cups of light orange​ paint, he needs 13 ounces of yellow paint and 3 ounces of red paint. Answer parts a and b.

Answers

Answer:

Arnie has enough red paint

Step-by-step explanation:

step 1

Find out the number of ounces of red paint needed to make 3 cups of dark orange paint

Let

x -----> number of ounces of red paint

y -----> number of ounces of yellow paint

z ----> cups of dark orange

we know that

\frac{x}{z}=\frac{7}{1}\ \frac{ounces\ red\ paint}{cups\ dark\ orange}

z

x

=

cups dark orange

so

For z=3 cups

substitute and solve for x

\frac{x}{3}=\frac{7}{1}

x

=

x=21\ ounces\ of\ red\ paintx=21 ounces of red paint

step 2

Find out the number of ounces of red paint needed to make 3 cups of light orange paint

Let

x -----> number of ounces of red paint

y -----> number of ounces of yellow paint

z ----> cups of light orange

we know that

\frac{x}{z}=\frac{3}{2}\ \frac{ounces\ red\ paint}{cups\ light\ orange}

z

x

=

cups light orange

so

For z=3 cups

\frac{x}{3}=\frac{3}{2}

3

x

=

x=4.5\ ounces\ of\ red\ paintx=4.5 ounces of red paint

step 3

Adds the ounces of red paint

21+4.5=25.5\ ounces\ of\ red\ paint21+4.5=25.5 ounces of red paint

25.5\ ounces < 32\ ounces25.5 ounces<32 ounces

therefore

Alex is trying to save $230 to buy a new tablet. Right now, he has $40 and can save $38 a week from
his allowance. Write and solve an inequality that can be used to find the minimum number of weeks it
will take Alex to have the money to buy the tablet. Write a sentence to interpret your solution.

Answers

Answer:

Step-by-step explanation:

So we know that Alex is trying to save $230.

He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.

If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.

38×5= 190

Therefore, Alex will have enough money to buy a tablet in five weeks.

I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

If ∠ G is supplementary to ∠ H and the measure of ∠ G is 65 ° what is the measure of ∠ H ?
Please help

Answers

Supplementary angles add up to = 180 degrees...so G + H = 180. To find H, subtract G from 180.
180 - 65 = 115
So angle H = 115 degrees

Measure of ∠H = 115°

What are supplementary angles?

Two angles are called supplementary when sum of their measures is 180 degrees.

Given,

∠G is supplementary to ∠H

∠G is 65 °

∠G + ∠H = 180°

65° + ∠H = 180°

∠H = 180° - 65°

∠H = 115°

Hence, 115° is measure of ∠H .

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [

Answers

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3
