Evaluate the expression -7 1/4x + 3 5/8 for x= -4
Misha Larkins [42]

Answer:

32 5/8 (or 32 and 5/8)

Step-by-step explanation:

Okay, so this problem is asking for us to solve this problem with the substitution of a variable: x = -4. Before we fully solve this problem, we need to replace all of those x variables with -4 so that it is easier to solve.

-7 1/4(-4) + 3 5/8.

To make this problem even easier to solve, let's turn these mixed numbers into improper fractions. To do this, multiply the denominator by the whole number. Then add the numerator to this number. The new number that you just got is now your new numerator for this number.

-29/4(-4) + 3 5/8.

Repeat the last step to turn the other mixed number into an improper fraction.

-29/4(-4) + 29/8.

Now let's multiply that -4 by 29/4. Because a whole number technically has a denominator of 1, we can now set up the next part of our problem. (The symbol * means multiplication since we can't use x since it is already being used as a variable in this equation.)

(-29/4 * -4/1) + 29/8.

29 + 29/8.

Now to solve the rest of this problem, let's convert the whole number of 29 so that it has a denominator of 8. This is that these two numbers are addable.

<u>29</u> x <u>8</u> = <u>232</u>

1   x 8 =   8

Now these numbers are addable. So:

232/8 + 29/8 = 261/8 = 32 5/8.

I hope that this helps.

Answer:

16%

Step-by-step explanation:

so you already know 35% like both and 17% like apples and 32% like neither

add those and get 84. we know that the percent is over 100 . So far you have 84% meaning there is only 16% left . Therefore 16% like bananas

What is the slope in the line formed by points (-1,-2) and (3,-3
tia_tia [17]

Slope of the line formed by points (-1,-2) and (3,-3) is Slope=\frac{-1}{4}

Step-by-step explanation:

We need to find slope of the line formed by points (-1,-2) and (3,-3)

Finding slope:

The formula used is:

Slope=\frac{y_2-y_1}{x_2-x_1}

here, x_1=-1,y_1=-2,x_2=3,y_2=-3

Putting values and finding slope:

Slope=\frac{y_2-y_1}{x_2-x_1}

Slope=\frac{-3-(-2)}{3-(-1)}

Slope=\frac{-3+2}{3+1}

Slope=\frac{-1}{4}

So, slope of the line formed by points (-1,-2) and (3,-3) is Slope=\frac{-1}{4}
