Answer:

A. 1 2/3

Step-by-step explanation:

I thought of it backwards and did 1 and 2/3 + 3 and 1/3 = 4 and 3/3

and that turns into 5

Answer:

8!

Step-by-step explanation:

I'm sure you're still really smart, you just don't understand it :)

Those two bars mean the absolute value of whatever's inside of them. Absolute value is always positive, so if you had 34 inside of the bars, it would still be positive 34.

Now that we know what those bars mean, the expression is really this:

1 + 7

I'm sure you can solve that :)

Answer: 8

Answer:

[tex]c=\frac{d + ab}{a}[/tex]

Step-by-step explanation:

Step 1: Write equation

[tex]a(c-b)=d[/tex]

Step 2: Solve for c

Answer:

c=d+ab/a

Step-by-step explanation:

a( c-b)= d

ac - ab= d

   +ab    +ab

ac= d-ab

/a      /a

c= d+ab/a

Answer:

D; A⊂U is true and A'={9, 10, 12, 14}

Step-by-step explanation:

A={11,13}

Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.

A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}

Answer: A and C are correct.

Step-by-step explanation:

Look at the proportions. For 8 cups of water there are 3 cups of lemon juice. So L 3/8(w)

For 8 cups of water there are 2 cups of sugar. 8 is 4 times 2. So the amount of water is 4 times the amount of sugar. W= 4s

Given:

A rectangular rug in her living room that is 6 feet wide and 8 feet long.

She orders a new one that covers twice as much area.

New rug is 1.5 times as wide as the original rug.

To find:

The length of new rug.

Solution:

We have,

Length of rug = 8 feet

Width of rug = 6 feet

Area of rug is

[tex]Area=length \times width[/tex]

[tex]A_1=8 \times 6[/tex]

[tex]A_1=48\text{ sq. feet}[/tex]

Area of new rug is twice of area of original rug.

[tex]A_2=2\times A_1[/tex]

[tex]A_2=2\times 48[/tex]

[tex]A_2=96\text{ sq. feet}[/tex]

New rug is 1.5 times as wide as the original rug.

Width of new rug = 1.5 × 6 = 9 feet

Let the length of new rug be x feets. So, area of new rug is

[tex]A_2=x\times 9[/tex]

[tex]96=x\times 9[/tex]

Divide both sides by 9.

[tex]\dfrac{96}{9}=x[/tex]

[tex]\dfrac{32}{3}=x[/tex]

[tex]x=\approx 10.67\text{ feet}[/tex]

Therefore, the length of new rug is about 10.67 feet.

Answer: 15.6

Step-by-step explanation: k/13 = 6/5 = 15.6

Answer:

x = 5

Step-by-step explanation:

Subtract x from both sides.

Your equation would look like this now:

5 = 1x

Divide both sides by 1.

x = 5

Hope you understand :)

Please consider Brainliest :)

[tex]x + 5 = 2x[/tex]

[tex]5 = 2x - x[/tex]

[tex]5 = 1x[/tex]

[tex]x = 5[/tex]

Let us check whether or not we have found out the correct value of x , by placing 5 in the place of x .

Which means :-

5 + 5 = 2 × 5

10 = 10

Hence proved that the value of x = 5 .

Therefore , 5 + 5 = 2 × 5 , ( x = 5 ) .

Answer:

  both size boxes are $18 each

Step-by-step explanation:

Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...

  3x +14y = 306

  7x +7y = 252

Doubling the second equation and subtracting the first, we have ...

  2(7x +7y) -(3x +14y) = 2(252) -(306)

  11x = 198

  x = 18

  y = 252/7 -x = 36 -18 = 18

A small box costs $18, as does a large box.

Answer:

both size boxes are $18 each

Step-by-step explanation:

Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...

3x +14y = 306

7x +7y = 252

Doubling the second equation and subtracting the first, we have ...

2(7x +7y) -(3x +14y) = 2(252) -(306)

11x = 198

x = 18

y = 252/7 -x = 36 -18 = 18

A small box costs $18, as does a large box.

Answer:

The fractions are not equivalent. If you cross multiply, 65 x 4 = 260 and 13 x 4 = 52. 260 > 52.

Answer:

Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Step-by-step explanation:

Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.

Number of scholars = 7

Total number of boxes [tex]=7x[/tex]

Total number of chocolate bars [tex]=(7x)(30)=210x[/tex]

Price of 1 chocolate bar = $2

Price of [tex]210x[/tex] chocolate bars [tex]=210x(2)=\$420x[/tex]

Also,

Total amount to be raised for travel expenses = $1680

So,

[tex]1680=420x\\x=\frac{1680}{420}\\ x=4[/tex]

Therefore,

each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Answer:

11,3

Step-by-step explanation: basic midpoint formula

Answer:

$13.75 per gallon

Step-by-step explanation:

To solve for any unit rate you use

[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]

Cross multiply.

So 68.75 = 5x

Divide both sides by 5 to get x alone.

13.75 = x

Therefore 1 gallon equals $13.75

Answer:

If you mean FOIL (as in first, outside, inner, last)

it is primarily used to distribute a factor properly.

Step-by-step explanation:

Putting values of m and n in the equation

12/3 + 5(3)

4 + 15 = 19

(12)(3)/4

= 36/4 = 9

3(12) - 12(3)

36 - 36 = 0

Step-by-step explanation:

m= 12 and n = 3

[tex]a. \: \frac{m}{3} + 5n \\ \frac{12}{3} + 5 \times 3 = 4 + 15 = 19[/tex]

[tex]b. \frac{ mn}{4} = \frac{12 \times 3}{4} = \frac{36}{4} = 9[/tex]

c.[tex]3m - 12n \\ \\ 3 \times 12 - 12 \times 3 = 36 - 36 = 0[/tex]

Answer:

She can write 2 pages and 4/5 extra.

Step-by-step explanation:

We know that she has already written for 1/14 of a minute. Now we need to turn that fraction into a whole, because the problem is asking for a whole minute.

___ x 1/14 = 1?

14

Now we take the 1/5, and multiply it by the 14 to see how much she writes in a minute.

1/5 x 14 = 14/5

Last we simplify.

14/5 = 2 4/5

Answer:

C(x) = 2x + 100

Step-by-step explanation:

Here, we want to find the formula for C(x)

Here, x will be the number of gallons of gas

so per day, if x gallons of gas were consumed, the daily cost here will be x * 2 = $2x

Adding the cost for the attendant, we have 2x + 100

So the formula for C(x) will be;

C(x) = 2x + 100

Step-by-step explanation:

To solve the figure. You need to split the shape up with the lines shown.

Let's solve the top triangle first.

The formula to find the area of a triangle is y = 1/2(b*h)

So the base is 2+2+6 which equals 10. And the height is 4.

So y = 1/2(4*10)

PEMDAS solve parentheses first.

y = 1/2(40)

y = [tex]20cm^{2}[/tex]

Now solve the bottom left one.

y = 1/2(2*2)

y = 1/2(4)

y = [tex]2cm^{2}[/tex]

Now the bottom right triangle.

y = 1/2(6*2)

y = 1/2(12)

y = [tex]6cm^{2}[/tex]

And to solve area of a square is

y = b*h

y = 2*2

y = [tex]4cm^{2}[/tex]

And add all of it up to get

y = [tex]20cm^{2}+2cm^{2} +6cm^{2} +4cm^{2} = 32cm^{2}[/tex]

Area = [tex]32cm^{2}[/tex]

Answer:

B) y = 35°                

Step-by-step explanation:

Any quadriteral is you can add a line that links opposite corners of the quadrilateral and split it into two triangles. Added a single line the links opposite vertices of the quadrilateral and that splits it into two triangles. The angle rule that angles in a triangle add up to 180 degrees so the angle must add up to 180 degrees because of that angle rule and then in the other triangle the angles in that one must add up to 180 degrees. But the quadrilateral is made up of both triangles so you need all the angle in both those triangles to make up the angles of the quadrilateral so two lots of 180 degrees make up for 360 degrees. (180° plus 180° = 360°)

B) 118° plus 67° pus y plus 4y = 360°          ( add all the angles that are inside of the quadrlateral)

185° plus 5y = 360°                   ( 118 degrees plus 67 degrees is 185°, 5y from to y plus 4y. its like you have 1y plus 4y)

5y = 360° - 185°           ( subtract 180 degrees from both sides)

5y = 175°

divide by both side by 5, the value of y is 35°

chemical energy

Food energy is chemical energy that animals (including humans) obtain from food through the process of cellular respiration (also called eating).

Answer:

a supplementary angles are adjacent angles that have a sum of 180 degrees

Step-by-step explanation:

if a supplementary angle measure up.to 180 degrees and x is 3 times the measure.of angle y then 3÷180 is equal to 60 then 60 degrees is the answer .
