Answer:

day 2

Step-by-step explanation:

4(h+2)-2 is 2h+8 and 3(2+h) is 3h+6, and if you do guess and check, when you fill h in as 2, both expressions equal 12.

On the 2nd day, their distance hiking is the same.

Given

Carla and George each went hiking.

The expressions [tex]4(h + 2) - 2h[/tex] and 3(2 + h) represent the respective distances Carla and George hiked each day.

Therefore,

On what day number h will their distance hiking be the same?

[tex]\rm 4(h+2)-2h = 3(2+h)\\\\4h+8-2h=6+3h\\\\2h+8=6+3h\\\\3h-2h=8-6\\\\h = 2[/tex]

Substitute the value of h in the equation first;

[tex]= 4(h+2)-2h\\\\= 4(2+2)-2\times 2\\\\=4(4)-4\\\\=16-4\\\\=12[/tex]

Substitute the value of h in the equation second

[tex]\rm =3(2+h)\\\\= 3(2+2)\\\\= 3\times 4\\\\= 12[/tex]

Hence, on the 2nd day, their distance hiking is the same.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

y ∝ 7x

y = 7x

Where y is the cost of the fresh peaches and x is the number of pounds.

The constant of variation is 7.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Bob paid $5.60 for 0.8 lb of fresh peaches.

This means,

0.8 lb = 5.60

Divide 0.8 on both sides.

1 lb = 5.60/0.8

1 lb = $7

Now,

y ∝ 7x

y = 7x

Where y is the cost of the fresh peaches and x is the number of pounds.

The constant of variation is 7.

Thus,

y ∝ 7x

y = 7x

Where y is the cost of the fresh peaches and x is the number of pounds.

The constant of variation is 7.

3. Car Mart sells one more car per day.

4. Winston started with more cars.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.

Rate for cart mart is (32 - 43)/(3 - 2) = - 11.

Car Mart sells 11 cars a day.

Winston's sells 10 cars per day.

Car Mart sells more cars per day.

As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.

As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.

Step-by-step explanation:

The difference in the cost per pound between the larger and smaller packages of shredded cheese will be $0.47.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A 2- pound package of shredded cheese is $6.98.

And, A ½ - pound package of shredded cheese is $1.98.

Now,

Since, A 2- pound package of shredded cheese is $6.98.

So, A 1- pound package of shredded cheese =  $6.98 / 2

                                                                     = $3.49

And, A ½ - pound package of shredded cheese is $1.98.

So, A 1 - pound package of shredded cheese = $1.98 x 2

                                                                      = $3.96

Thus, The difference in the cost per pound between the larger and smaller packages of shredded cheese = $3.96 - $3.49

                                                            = $0.47

Therefore, The difference in the cost per pound between the larger and smaller packages of shredded cheese will be $0.47.

Answer:

[tex]\displaystyle y=8x[/tex]

Step-by-step explanation:

We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.

So, we will first need to determine the slope. We can use the slope formula:

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

Where (x₁, y₁) and (x₂, y₂) are two points.

We have three points: (1, 8), (2, 16), and (3, 24).

Let’s pick two. We can use (1, 8) and (2, 16).

So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{8}{1}=8[/tex]

So, our slope is 8.

Now, we can determine the equation using point-slope form:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is our slope and (x₁, y₁) is a point.

We know that the slope is 8, so we will substitute 8 for m.

We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:

[tex]\displaystyle y-8=8(x-1)[/tex]

Solve for y. Distribute the right:

[tex]\displaystyle y-8=8x-8[/tex]

Add 8 to both sides:

[tex]\displaystyle y=8x[/tex]

And we have our equation.

Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.

Answer:

4)71-x=180

x=109

5)60-x=180

x=120

Step-by-step explanation:

4) 32+72=109, 109-180=71, 71-180=109

71 is the last measure of the triangle so you just subtract that from 180.

5)180-60=120

Answer:

3/4

Step-by-step explanation:

If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in

1/4(x)=y

1/4(3)=y

3/4=y

And the other one is incorrect

1/4(x)=y

1/4(7)=y

1 3/4 =y
