Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Hope this helps.

Step-by-step explanation:

[tex]\pi[/tex] x [tex]5^{2}[/tex]

Answer:

78.5

Step-by-step explanation:

The formula for the area of a circle is A=πr^2.  The radius, (r) is half of the diameter.  The diameter of this circle is 10 in, so the radius is 5 in.  Plug 5 into the formula A=πr^2 to get A=π5^2.  Square 5 to get 25 and plug it back in the formula to have A=25π.  Multiply pi (π, 3.14) by 25 to get 78.5.

*Colton could sell 10 tacos and 100 burritos.

​Step-by-step explanation:

Hope I helped ^u^

Colton can sell 20 tacos and 100 burritos.

An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.

Given that, Colton can make 120 tacos or burritos in total, the taco for $3.75 and each burrito for $6, He must sell at least $540 worth of tacos and burritos each day,

Establishing the inequality,

x + y ≤ 120............(i)

3.75x + 6y ≥ 540

0.625x + y ≥ 90...........(ii)

Plotting the graph, the solution will be the portion covered by both the inequality.

One of the possible solution is = (20,100)

Hence, Colton can sell 20 tacos and 100 burritos.

Answer:

90 pumpkin and 36 green beans

Step-by-step explanation:

Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.

Answer:

9 cans

Step-by-step explanation:

126/7=18

18/2=9

Answer: $3.60

Step-by-step explanation:

If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.

4.8 x 0.75 = 3.6.

Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!

Answer:

Grapes

Step-by-step explanation:

The rate of change for the grapes was -12 grapes per minute.

To calculate the rate of change for the carrots, use the slope formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex]. In this case, m is the rate of change, time is x, and the carrots remaining is y.

[tex]m = \frac{118-136}{8-6} = \frac{-18}{2} = -9[/tex]

The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.

If the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that, the students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining.

Grapes were changing at a pace of -12 grapes per minute. Use the slope formula to get the rate of change for the carrots.

m=118-136/8-6

m=-18/2

m=-9

The students consumed the grapes more quickly because the decline in grapes was significantly larger than the decline in carrots.

Thus, the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

Step-by-step explanation:

After t  years,

 the first tree will be 13+4t feet tall

 the second tree will be 27+½t feet tall.

When they are the same height,

13+4t = 27+½t

subtract ½t from both sides

13+3½t = 27

subtract 13 from both sides

3½t = 14

divide both sides by 3½

t = 14÷(3½) = 14÷(7/2) = 14× (2/7) = 4

The trees will be the same height in 4 years.

Answer:

84 and 140

Step-by-step explanation:

Jack chooses two numbers between 50 and 150

The two numbers have a Lowest Common Multiple (LCM) of 420

Factors of 420 between 50 to 150

= 60, 70, 84, 105, 140

We are also told that:

They have a Highest Common Factor (HCF) of 28

Hence, we find out of the factors above, which numbers can be divided by 28 without having any remainder.

60/28 = 2.1428571429

70/28 = 2.5

84/28 = 3

105/28 = 3.75

140/28 = 5

Therefore, the two numbers are

84 and 140
