Answer:

-2

Step-by-step explanation:

To find the slope, you can do rise (change in y)/run (change in x). Take the points (0, 0) and (3, -6) There is a change of -6 in the y-direction (you can count on the graph) and a change of +3 in the x-direction. Using this, rise/over run, plug in -6/3 to get -2 as the slope.

Step-by-step explanation:

Mrs Oliver uses approximately 275 liters of water in one day.

To find how much water she uses in 28 days, multiply 275 by 28:

     2 7 5

     × 2 8

--------------

  2 2 0 0

+ 5 5 0 0

--------------

  7 7 0 0

Given :

[tex]\longrightarrow \sf \qquad {6x}^{2} + 10x - 56[/tex]

⠀

We can write it as,

[tex]\longrightarrow \sf \qquad2 \bigg({3x}^{2} + 5x - 28 \bigg)[/tex]

⠀

We have to find the two numbers a and b such that,

⠀

[tex]\longrightarrow \sf \qquad a + b = 5[/tex]

[tex]\longrightarrow \sf \qquad a b = 84[/tex]

⠀

Obviously, the two numbers are 7 and 12.

[tex]{\longrightarrow \sf \qquad2 \bigg({3x}^{2} - 7x + 12x- 28 \bigg)}[/tex]

[tex]{\longrightarrow \sf \qquad2 \bigg[x \bigg(3x-7 \bigg) +4 \bigg(3x-7\bigg)} \bigg][/tex]

[tex]{\longrightarrow \sf \qquad{2 \bigg(3x - 7 \bigg) \bigg(x + 4\bigg)}}[/tex]

⠀

Therefore,

[tex]{\longrightarrow \bf \qquad{2 \bigg(3x - 7 \bigg) \bigg(x + 4\bigg)} \: is \: equivalent} \bf \: \: to \: \: {6x}^{2} + 10x - 56[/tex]

Let, number of small, medium and large popcorn sold are s, m and l respectively.

So, s + m + l = 250    ....1)

Also, l = 2s     ....2)

Total sum = $1726 = 2s + 5m + 10l     .....3)

Putting value of l from 2) to 1) is :

s + m + 2s = 250

m + 3s = 250    

m = 250 - 3s      ....4)

Putting value of m and l in terms of s in equation 3)

We get :

2s + 5( 250 - 3s ) + 20s = 1726

7s = 1726 - 1250

s = 68

l = 136

m = 250 -3(68) = 46

Now,

[tex]P_s=68\times 2 = \$136\\\\P_m = 46\times 5 = \$230\\\\P_l = 136\times 10 = \$1360[/tex]

Hence, this is the required solution.

Answer:

-1

Step-by-step explanation:

To visualize this on a number line you are moving four spots over to the left of 3 (since it is to the left, it is a negative four). 3 to 2 is the first movement to left, 2 to 1 is the 2nd movement, 1 to 0 is the third movement, and 0 to -1 is the fourth movement to the left.

4 hours, 45 minutes=4.75 hours

5 hours, 30 minutes=5.5 hours

6 hours, 15 minutes=6.25 hours

4.5 + 4.75 + 5.5 + 6.25 = 21.00 hours

No solution. This method proves to be incorrect.

Answer:

52.5 miles

Step-by-step explanation:

5 miles = 8 km

→ Find how many miles in 1 km

8 km = 5 miles

1 km = 0.625 miles

→ Multiply both sides by 84

84 km = 52.5 miles

Answer:

ok what is the question

Answer:

p=-6

Step-by-step explanation:

the first thing to do is to add all like terms for example [tex]\frac{1}{3}[/tex]p+[tex]\frac{1}{2}[/tex]p would turn into [tex]\frac{2}{6}[/tex]p+[tex]\frac{3}{6}[/tex]p to make it so we can add them together which after we add both of those p's together we get [tex]\frac{5}{6}[/tex]p which now we have [tex]\frac{5}{6}[/tex]p+7=[tex]\frac{7}{6}[/tex]p+5+4 which now we add 5 and 4 which we get 9 which now the equation looks like [tex]\frac{5}{6}[/tex]p+7=[tex]\frac{7}{6}[/tex]p+9 which now we subtract 7 from 9 and we are left with 2 so now the equation is [tex]\frac{5}{6}[/tex]p=[tex]\frac{7}{6}[/tex]p+2 which now we subtract [tex]\frac{7}{6}[/tex]p from [tex]\frac{5}{6}[/tex]p and we are left with -[tex]\frac{2}{6}[/tex]p=2 which now we divide both sides by -[tex]\frac{2}{6}[/tex] which makes the equation look like p=2÷-[tex]\frac{2}{6}[/tex] which equals -6 so all we are left with is p=-6

50 > 6t - 4e

I tried my best

Answer:

Greg could trim trees anywhere more than 7.67 hours for more than $50.

Step-by-step explanation:

First, set up the equation. Since he doesn't have a fixed number of dollars to earn (it is more than $50, not just $50), this would be an inequality.

50 < 6t - 4

50 is the principle goal, 6t because t is hours, and he gets $6 every hour, and - 4 because he pays a one time fee for equiment.

Then, you solve the inequality the way you would with one-variable inequalities:

50 < 6t - 4

46 < 6t

7.67 < t

Answer:

The amount of decrease is 2 and the percent decrease is 75%

Step-by-step explanation:

Amount of decrease

The magnitude of the Force F2 is; 12 N

According to newton's third law of motion which states that to every action there is an equal and opposite reaction, since F1 has a magnitude of 12N, it means that F2 will be an equal force acting in the opposite direction.

Now, since the force F2 is equal and opposite to F1, then F2 = 12 N
