you can actually use a calculator for this.

1,872 muffins packaged into boxes that hold 12 muffins.

that means 1,872/12

which is 156

Answer:

it is 156

Step-by-step explanation:

120°

180 - 130 = D = 50°

180 - (70+50) = 60°

then... 180 - 60 = 120°

Answer:

D= −50t + 300

Step-by-step explanation:

Since Dominic lives 300 miles from City A, when he starts his trip (at time

t=0), his distance from City A must be 300 miles, meaning D=300 when

t=0, which is the y−intercept.

                                    (0,300) is a point on the graph

Since Dominic will drive 50 miles per hour, the Dominic's distance from City A decrease 50 miles for each hour of driving, making the slope of D equal to

−50.

                                                   Slope=−50

                          equation of the line: D= −50t + 300

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 4 is an equation.

We have,

Distance between Dominic's house and City A = 300 miles

Speed = 50 miles per hour.

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

Now,

We can see that,

At t = 1, D = 300 - 50 = 250 miles.

At t = 2, D = 300 - 100 = 200 miles.

Thus,

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

Answer:

y = [tex]\frac{5}{4} x - 7[/tex]

Step-by-step explanation:

Step 1: Add -5x to both sides.

5x − 4y + −5x = 28 + −5x

−4y = −5x + 28

Step 2: Divide both sides by -4.

[tex]\frac{-4y}{-4} =\frac{-5x +28}{-4}[/tex]

Answer:

80%

Step-by-step explanation:

We are told that 1,200 students wore their school colors of green and white.

Also, we are told that 300 students did not wear school colours green and white.

Thus, total number of students = 1200 + 300 = 1500

Thus;

percent of the school population who wore their school colors is; (1200/1500) × 100% = 80%

Answer:

x=6

Step-by-step explanation:

Basically since 6x and 2x have like terms you subtract the 2x from 6x.

6x-2x=4x

Then you divide 4 from 24.

4x=24

4x/4 = 24/4

x=6

Answer:

6x - 2x = 24

4x = 24

4x ÷ 4 = 24÷4

x = 6

Step-by-step explanation:

First of all subtract 2x from 6x which will give you 4x = 24

since you're finding x or want to make x the subject you are to divide both sides by 4, so

4x ÷ 4 will give you x, since both 4's will cancel out giving you x =, then you divide 24 by 4 also. 24 ÷ 4 will give you 6, so x = 6.
