Answer:

C

Step-by-step explanation:

No slope is given so your slope is 0. Since both have no slope, they are both flat and therefore parallel

Let the number is x.

3/4 of a number is 120:

What is three-eights of the number:

Step-by-step explanation:

1. -3x+7x=18

    x(-3+7)=18

      x=[tex]\frac{18}{(-3+7)}[/tex]

2. 4x+7x=-5

Answer:

y-4 =-5(x+1)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y-4 = -5(x- -1)

y-4 =-5(x+1)

Answer:

y-4 = -5 (x- (-1))

Answer:

x=-4

Step-by-step explanation:

Switch sides:

−8x−3=29

Add 3 to both sides:

−8x−3+3=29+3

Simplify:

−8x=32

Divide both sides by −8:

−8x/−8 = 32/−8

Simplify again for the result:

x=−4

Percent go on 1 side

125

----       125% out of 100%

100

35 next to 125% due to the unknown amount of votes on the other side

P goes under 3 and the answer is A

Answer:

A.

Step-by-step explanation:

125% = 35 votes

100% = p

Answer : A

do the proportion and u get

[tex]\frac{125}{100} =\frac{35}{p}[/tex]  

p = 100*35:125 = 3500:125 = 28

Answer:

-4,-8 : 8,8

Step-by-step explanation:

Answer:

1.5 seconds

Step-by-step explanation:

Since f(x) represents the distance from the ground to the rock (in feet), we just need to find the values of x for which f(x) = 340. Substituting f(x) = 340 into f(x) = -16x² - 4x + 382 gives us:

340 = -16x² - 4x + 382

0 = -16x² - 4x + 42 (Subtract 340 from both sides)

16x² + 4x - 42 = 0  (Multiply entire equation by -1, "flip" equation)

8x² + 2x - 21 = 0    (Divide entire equation by 2)

(4x + 7)(2x - 3) = 0  (Factor LHS)

4x + 7 = 0 or 2x - 3 = 0 (Zero Product Property)

4x = -7 or 2x = 3 (Subtract -7 and add 3 from/to both sides, respectively)

[tex]x = -\frac{7}{4} =-1.75 . or .x= \frac{3}{2} = 1.5[/tex]

x = -1.75 is an extraneous solution because in the context of the question, you can't have negative seconds so therefore, the final answer is 1.5 seconds.

Answer:

$2.25

Step-by-step explanation:

5 lbs = $11.25

The unit price in this context means the price of a 1-pound bag of dog food so you would divide $11.25 by 5:

$11.25 ÷ 5 = $2.25

Hope this helps!

Answer:

2.25 ($) per pound

Step-by-step explanation:                                                                               11.25 /  5 = 2.25 per pound   Alternative workings we simply divide by 10  to find   11.25 / 10  = 1.125 then multiply by 2                                                      1.125 * 2  = 2.25 ($) per pound

Answer:

1/6

Step-by-step explanation:

2/3 of the class has a dog, and 1/4 of the class has a cat. This means that some people will have both a cat and a dog.

You have to find the fraction of students who have both, so you have to multiply 2/3 and 1/4, 2*1 = 2, and 3*4 = 12, so the fraction is 2/12.

2/12 can be simplified to 1/6.

So, the amount of students in the class that have both a cat and a dog are 1/6.

Answer:

The answer is 1/6.

Answer:

y - 3 = - 1/4(x + 2)

Step-by-step explanation:

m = - 1/4

Point = (-2,3)

y-intercept = 3 - (- 1/4) (-2)

= 3 - 1/2 = 5/2

y = - 1/4x + 5/2

Answer:8

Step-by-step explanation:

Answer:

7 minutes.

Step-by-step explanation:

You can simply apply the well known rule if time: 60mins makes 1 hour,

or use proportion;

where x is the value you seek,

4=240

x=420

The relationship between 4 and 249 is 60 so,

420 divided by 60 equals 7 minutes.

Answer:

w would be like 33 and x would be 45

Answer:

x=66, w=48

Step-by-step explanation:

since this is an isocsles triangle, x and angle j would have to have the same measure, 66 degrees. When you add 66 and 66 together, you can get the sum of angle j and x which is 132. You can subtract 132 from 180 (since all angles of the triangle add up to 180) to get w

180-132=48

so x=66 and w=48

Answer:

[tex] \frac{17}{40} [/tex]

Step-by-step explanation:

[tex] \frac{4}{5} - \frac{3}{8} [/tex]

First, find the common denominator

So we multiply 4 by 8, and get 32

Then we multiply 3 by 5, and get 15

Next we give both terms new denominators 5 × 8 =40

So now our fractions look like this:

[tex] \frac{32}{40} - \frac{15}{40} [/tex]

Now...that our denominators match we can simply

subtract the numerators

32 − 15 = 17

Thus the answer is:

[tex] \frac{17}{40} [/tex]
