Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 5 yards of fabric , plus 20 % extra . How much fabric did Jessica buy ?

Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.

Answer:

x=4

Step-by-step explanation:

You set the equation up like this

3x+2x-2=18

5x-2=18

5x=20

x=4

Answer:

x = 92/11

Step-by-step explanation:

10x + 1 + 12x - 5 = 180

*group the like terms*

(10x + 12x) + (1-5) = 180

*simplify*

22x - 4 = 180

*add four on both sides to cancel out -4*

+4. +4

*simplify*

22x = 184

*divide both sides by 22 to cancel out the quantity and solve for x*

÷22 ÷22

*simplify*

x = 92/11

Answer:

x = 92/11, x = 8.36 repeating the .36, or x = 8 4/11

Step-by-step explanation:

Answer:

A function that changes the same way can be a linear function.

y = a*x + b.

Where the rate of change (this is, how much changes y when x increases or decreases) is defined by the coefficient a, that is constant.

for example, suppose that when x = x0, we have y = y0

y0 = a*x0 + b.

Now x0 increases by one unit, to (x0 + 1)

y = a*(x0 + 1) + b = (a*x0 + b) + a = y0 + a.

Then if x increases (or decreases) 1 unit, y increases (or decreases) a units.

Now, we can define the rate of change of a function as it's derivate with respect to some variable.

In this case, if we derive with respect to x, we have:

y' = a

Then the rate of change is constant.

Answer:

476.91 Liters

Step-by-step explanation:

Lets start by figuring the liters per gallon amount. 63 times 3.785 equals 238.455. Since we have 2 barrels, we need to multiply this by 2 in order to get a grand total of 476.91 liters of oil.

Answer:

I believe its 8.18 hope I helped. =)

Answer:

8.1785 to the nearest hundredth is 8.18.

Step-by-step explanation:

1. I left 8. and change the .1785 because 17 is the hundredths place. Next I took the .1785 and rounded it to .18 because the 85 is above 50.

2. I put the two numbers together (8. & .18) and I got 8.18.

I hope this helps:)

Answer:

x=10 y=7

Step-by-step explanation:

1) 2(5x-5)=(6x+50)

2) 10x-10=6x+50

3) 4x-10=50

4) 4x=40

5) x=10

1) 7y-9=5y+5

2) 2y-9=5

3) 2y=14

4) y=7

Answer:

x=15, y=7

Step-by-step explanation:

Set up each equation to each angle's vertical angle.

Solve for x.

2(5x-5)= 6x+50

10x-10=6x+50

x= 15

Solve for y.

5y+5= 7y-9

y=7

Answer:0.78

Step-by-step explanation:

Answer:

Options (B) and (C)

Step-by-step explanation:

Farmland owned by Dwight = 1600 acres

He wants to divide his farmland into four equal parts.

So the area of each part of the land will be = [tex]\frac{\text{Area of the farmland}}{\text{Number of parts of the farmland}}[/tex] = [tex]\frac{1600}{4}[/tex]

This expression can be written in different ways,

[tex]\frac{1600}{4}=[/tex] 1600 ÷ 4

      [tex]=1600\times \frac{1}{4}[/tex]

Therefore, Options (B) and (C) will be the correct options.                                                                        

Answer:

2 x 3

Step-by-step explanation:

Since it starts at and goes right twice in intervals of 3, you can conlude that the answer would be 2 x 3 because it corresponds with the previous numbers stated.

Answer:

10/12 also 5/6

Step-by-step explanation:

Answer:

10/12 or the simplified version 5/6

Step-by-step explanation:

you have to multiply 2/3 by the reciprocal of 4/5 which is 5/4

so you write down 2/3 times 5/4 (just multiply across so it's 2x5 over 3x4)

2x5=10 and 3x4=12

10 is the numerator and 12 is the denominator

simplify if the problem calls for it by dividing the top and bottom numbers by 2
