Answer:

6x

Step-by-step explanation:

7x - x

X by itself is the same thing as 1x.

So, if we rewrite the equation using 1x instead of just x:

7x - 1x

Now, we can subtract like we normally would.

7x - 1x = 6x

80 inches

Step-by-step explanation:

Formula: 2l + 2w = perimeter

The equation that describes the relationship is option A. y = 8 - 7x.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given are the values of x and y.

x : 0  1  2  3

y : 8  1  -6  -13

Equation of a line can be written as y = mx + d in slope intercept form.

m is the slope and d is the intercept along Y axis.

Slope of a line with two points (x, y) and (x', y') is,

Slope = (y' - y) / (x' - x)

Consider the points (0, 8) and (1, 1).

Slope, m = (1 - 8) / (1 - 0) = -7 / 1 = -7

Since we already have the point (0, 8), y intercept, d = 8.

Substituting these, we get the equation of line as,

y = -7x + 8 or

y = 8 - 7x

Hence the equation of the line is y = 8 - 7x.

Answer:

x = -9

Step-by-step explanation:

multiply 2 on both sides which cancels out the 2 in the fraction and then do -1 times 2 and 2 times x (which is just 2x). After doing that your equation should look like 3x + 7 = 2x - 2

Collect your like terms (the numbers with an x variable go togther and the ones with an x have to be together) and rearrange it so it looks like: 3x - 2x = -2 - 7 after you have this written subtract 3 from 2 now because they're on the same side which leaves you with x (usually we leave out the one because it doesn't make a difference) so now you're left with x = -2 - 7 for this step subract -2 from 7 which leaves you with x = -9

Steps:

3x + 7 = 2x - 2

3x - 2x = -2 -7

x = -2 - 7

x = -9

Step-by-step explanation:

If you do the problem backward and apply the discount and taxes to 20$, then you get 18.70

The price of Jade's lunch on the menu will be;

⇒ $17.05

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

For lunch, a restaurant discounts prices on their menu by 15% and then applies a 10% sales tax to the discounted price.

And, Jade pays $18.70 after the discount and sales tax are applied.

Now,

Let the price of Jade's lunch on the menu = x

Since, A restaurant discounts prices on their menu by 15%.

Hence, The discounted price = x - 15x/100

And, Then applies a 10% sales tax to the discounted price.

Hence, The price = 10% of (x - 15x/100) + x

                           = 10/100 × 85x/100 + x

                           = 850x/10000 + x

                           = 17x/200 + x

                           = 217x/200

Since, Jade pays $18.70 after the discount and sales tax are applied.

Hence, We get;

⇒ 217x / 200 = 18.50

⇒ x = $17.05

Thus, The price of Jade's lunch on the menu will be;

⇒ $17.05

3. =

Step-by-step explanation:

100x8=800, 4*7=28, multiplied by 25 is 700, therefore making 800 greater than 700. Whenever comparing two multiplication problems, multiplying large numbers produces large results, so whichever starts larger will have an end result that is larger. 100 was large and it is smaller to its counter 25.

36 elevens really means 11x36, which is 396. 40 elevens really means 40x11, which is 440 minus 11x3 which is 407. 407 is greater than 396. The same logic applies here as the previous answer, the only difference is that the removal of three elevens is still larger than 36 elevens in this case.

12x24=288, 6x24=144, doubled makes it 288. In this case, the six is half of the twelve to begin with and then is made up for later by the fact that it is doubled.

When I solve math questions like these, I ignore the fact that it doesn't want a mathematical answer, do the math anyway and pull logic from it. (If your teacher checks, do it on a separate piece of paper, and then toss it.)

Basically you have your candy and you split it up, which is dividing, and give the groups of candy to your friends.

Answer:

2.9 minutes

Step-by-step explanation:

Given

[tex]Rate = 12 gallon/minute[/tex]

[tex]Size = 35\ gallon[/tex]

Required

Determine the time spent

The rate is a ratio of size to time

So, it can be expressed as:

[tex]Rate = \frac{Size}{Time}[/tex]

Substitute values for Rate and Size

[tex]12 = \frac{35}{Time}[/tex]

Cross Multiply

[tex]12 * Time = 35[/tex]

Solve for Time

[tex]Time = 35/12[/tex]

[tex]Time = 2.9[/tex] (approximated)

Step-by-step explanation:

The total bill will be the sum of the rent and the cost for the total time spent.

Step-by-step explanation:

The solution of an equation is x= -1.11 and x = 2.11.

A polynomial equation of the second degree is quadratic, which means that at least one of its terms must be squared. Quadratic equations are another name for it. The quadratic equation generally looks like this:

ax² + bx + c = 0, where x is a numerical coefficient and a, b, and c are unknown variables.

Given equation -3x² + 2x + 4 = -x - 3

simplify the equation we get

3x² - 2x - 4 -x -3 = 0

3x² - 3x - 7 = 0

The equation is solved by the Quadratic formula

x =  (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex])/2a

a = 3, b = -3, c = -7

x = [-(-3) ± [tex]\sqrt{(-3)^{2} - 4(3)(-7)}[/tex]]/2(3)

x = (3 ± 9.643)/6

taking positive sign

x = 12.643/6 = 2.1072 = 2.11

taking negative sign

x = -6.643/6 = -1.1072 = -1.11

Hence the values of x are -1.11 and 2.11

The correct choices are 29 feet = 348 inches, 352 yards = 0.2 miles, 372 feet = 124 yards, and 2 miles = 10560 feet.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have the ratio conversion table given.

mile: yard = 1: 1,760

yard: foot = 1 : 3

foot: inch = 1: 12

From the given conversion table:

29 feet = 29×12 inches

29 feet = 348 inches

Similarly,

352 yards = 0.2 miles   (1 yard = 1,760 miles)

372 feet = 124 yards

2 miles = 10560 feet  

Thus, the correct choices are 29 feet = 348 inches, 352 yards = 0.2 miles, 372 feet = 124 yards, and 2 miles = 10560 feet.
