3.5+y=-1 solve for y

Answer:

x = 3

Step-by-step explanation:

y = 2/3 x + 5; y = 7

7 = (2/3)x + 5

2 = (2/3)x

x = 2 * 3/2

x = 3

Answer:

x=3

Step-by-step explanation:

To start all you need to do is replace [tex]y[/tex] with 7 to get [tex]7=\frac{2}{3}x+5[/tex]

Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get [tex]2=\frac{2}{3}x[/tex]

Finally, you divide both sides by [tex]\frac{2}{3}[/tex]. You divide fractions by multiplying the reciprocal like so [tex]\frac{2}{1} *\frac{3}{2} =x[/tex] to get [tex]\frac{6}{2} =x[/tex]. This means that x=3

Answer:

x = 2

Step-by-step explanation:

2x + 20 = 12x

First, we have to put our exponent on the same side of our equation

2x + 20 = 12x

-2x            -2x

20 = 10x

Now, we have to divide by 10 on both sides to get our exponent on its own (x)

20 = 10x

÷10   ÷10

2 = x or x =2

Hope this Helps! :)

Answer:

13 9/14

Step-by-step explanation:

Add the blue + red fabric

1. Make the denominator the same

6 7/14 + 7 2/14

2. Add

6 7/14 + 7 2/14 = 13 9/14

Answer:

13 9/14

Step-by-step explanation: You would change 1/7 into 2/14 for a common denominator then add 2/14 and 7/14 and get 9/14 and 6+7=13 so it would be 13 9/14. Plzzzz give me brainliest

Answer:

4:141

Step-by-step explanation:

first, wright out a ratio with what's given

20(teachers):705(students)

next, simplify the ratio by dividing both sides by the gcf

20: 705

20/5 : 705/5

4 : 141

Answer:

0.000425 and 62570000000.

Step-by-step explanation:

Answer:

1) 425000

2) 62.570000

Step-by-step explanation:

There are 5 under the 10.

1) 10 x 10 x 10 x 10 x 10 = 100000

100000 x 4.25 = 45000

2) There are 7 under the 10.

10 x 10 x 10 x 10 x 10 x 10 x 10 = 10000000

10000000 x 6.257 = 62.570000.

If you don't understand, count the "0's" and times then by 1 and 0's.

Answer:

C and D!

Step-by-step explanation:

For A, two is greater than negative four, so that eliminates that right off the bat.

In B, -1/3 is greater than -1/6, so that choice is wrong.

E, -3/4 is greater than negative three, so that is also wrong!

C and D are correct!

Answer:  [tex]x \le -1[/tex]

=================================================

Explanation:

The domain is the set of all possible x values of a function.

The largest x can get is x = -1, since this x value applies to the x coordinate of the right most point on the curve. The filled in circle indicates we include this endpoint as part of the domain.

There is no smallest x value due to the arrow showing the curve goes on forever in that direction.

We can write the domain as [tex]-\infty < x \le -1[/tex] but it's better to write [tex]x \le -1[/tex]

Put another way: the domain consists of values that are -1 or smaller.

Answer:

You have written 26 pages in total.

Step-by-step explanation:

I always enjoyed adding fractions. Something about it is so... simple.

The problem is basically asking us to add 20 1/2 and 5 1/2 together.

I would first suggest adding both halves together, to make 1.

That way, we're left with 20 + 5 + 1. That seem easier, doesn't it?

Then we would add 20, 5 and 1 together, to get 26 whole pages.

And that, to an extent, is how I did it.

Hope this helps! :D

Answer:

Given:

Written pages for Act 1 = 20 1/2

Written pages for Act 2 = 5 1/2

For making mixed numbers like this easier to add, let's convert them first into an irrational number with this formula,

((Whole Number × Denominator) + Numerator)/Denominator

Thus,

for 20 1/2

((20 × 2) + 1)/2 = 41/2

for 5 1/2

((5 × 2) + 1)/2 = 11/2

Then we add,

41/2 + 11/2

Since, they have the same denominator, no more conversions need, proceed adding the numerators,

(41 + 11)/2 = 52/2 = 26

You've written 26 pages in total.

Answer:

324 calories

Step-by-step explanation:

A box of cereal states that there are 81 cal in a 3/4 cup serving what is the unit rate for calories per cup how many calories are there in 3 cups of cereal

The unit rate for calories per cup = calories per cup

3/4 cup serving = 81 calories

3 cups of cereal = x calories

We Cross Multiply

3/4 × x = 81 × 3

x = (81 × 3) ÷ 3/4

x = 243 × 4/3

x = 324 calories per cup

There are 324 calories in 3 cups of cereal

Intro:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So first we will do 180-152 to get the measure of the angle besides the angle. That'll give us 28, then we know that those base angles of this mini triangle are congruent so we will do 28+28 to get 56. Now we will do 180-56 to get the last angle of the triangle, which is 124. And this angle is the same as the angle with x because they are corresponding angles so x is 124°.
