Giving brainless to the correct answer I need it asap!

Answer:

It's the B

Step-by-step explanation:

0.3*4=1.2

0.3 *(-8)=-2.4

-0.5*(-2.4x)= 1.2x

-0.5*4=-2

So it's 1.2x - 2.4 + 1.2x - 2

Answer:its B

Gallons (volume) and feet (length) are not compatible units. I guess you mean cubic feet.

Apparently, 1 gal = 231 in³, so

32 gal/min

= (32 gal/min) • (231 in³/gal) • (1/12 ft/in)³ • (1/60 min/s)

= (32 • 231) / (12³ • 60) ft³/s

= 77/1080 ft³/s

≈ 0.0713 ft³/s

Answer:

B

Step-by-step explanation:

An integer is a whole number (not including 0).  An integer's opposite can be found by adding a negative sign to the front of it.  A negative integer's opposite would be positive, while a positive integer's opposite would be negative.

Step-by-step explanation:

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

[tex]y = mx+b[/tex]

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]

Putting slope in general equation

[tex]y = -8x+b[/tex]

Putting (-6,9) in the equation

[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]

Putting the value of b we get

[tex]y = -8x-39[/tex]

Hence,

Equation of line in slope-intercept form is: y = -8x-39

Answer:

140

Step-by-step explanation:

x = 7  ; y = -2

7(2x - 3y) = 7(2*7 - 3*[-2])

               = 7(14 + 6)

              = 7 * 20

               = 140

Step-by-step explanation:

this is what I believe the answer is and the work for it

Answer:

a. The situation is discrete for the domain and continuous for the range.

b. i.  651 ≤ x ≤ 812. ii. $ 195.3 ≤ x ≤ $ 243.6.

Step-by-step explanation:

a. This is because we can only have a whole number of students which in turn leads to a whole number of candies. Also, since the cost of each candy box is $ 3/10 = $ 0.3, it is a real number. So, the total cost of candy will also be a real number. Thus, the situation is discrete for the domain and continuous for the range.

b. i. Let x be the number of students which also equals number of candies to be bought. Since there are 7 teams and between 93 and 116 students per team, the minimum number of students is 93 × 7 = 651 and the maximum number of students is 116 × 7 = 812. So, the domain, the number of candies is 651 ≤ x ≤ 812.

ii. The range of the function is the cost of the candies. Since the cost of the candies is $ 3 per box and there are 10 per box, each candy costs $ 3/10 = $ 0.3. So the total cost of candies C = cost per candy × number of students = $0.3x.

So, the range of the candies is the minimum and maximum values of students times $ 0.3. So, 651 × $ 0.3 ≤ x ≤ 812 × $ 0.3 = $ 195.3 ≤ x ≤ $ 243.6

Answer:

x=56

Step-by-step explanation:

number = x

7/8x=8/7x-15

Add 15

15+7/8x=8/7x

Subtract 7/8

15=15/56x

x=56

The number is 56

Hope this helps!

Answer:

x = 2

Step-by-step explanation:

[tex]37x + 2 = 38x\\=> 38x-37x=2\\=> x = 2[/tex]

Answer:

x=2

Step-by-step explanation:

37x + 2 = 38x

<=> 2 = 38x - 37x

<=> 2 = x

So x = 2

Answer:

Step-by-step explanation:

Answer: 0.1 liter

Step-by-step explanation:

From the question, we are informed that Brianna teacher gives her a container that has 0.25 liter of a liquid in it and she needs to use 0.4 of this liquid for the experiment.

The amount of liquid that Brianna will use will be:

= 0.4 × 0.25 liters

= 0.1 liter

when you have a negative square number, you do + and - the square root :) it would not work if you were given +25

Answer:

J = 7.5

Step-by-step explanation:

* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *

First, start off by adding all of the like numbers.

11 + (-3) + 7 = 8 + 7 = 15

- 1/8 j - 3/8 j  = - 4/8 j.

Combining those two sums, we get:

15 - 4/8 j = 0

Subtract 15 from both sides,

-4/8 j = -15

Simplify -4/8 to -1/2, and then to -0.5

-0.5j = -15

Divide.

-15/-0.5 = 7.5

When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5

If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.
