Answer:

t = -14

Step-by-step explanation:×

I did 4+3 which equals 7.

Now I know I need t/-2 to equal 7.

Next, I did 7×2 which equals 14.

When you divide 2 negative numbers you get a positive number.

So -14 ÷ -2 = 7

So t = -14

Step-by-step explanation:

don't get mad if im wrong lol I tried

How to Solve:

So first start with the parentheses, which just rewrites the problem too -4+3n-5-7n. Next, you want to add like terms, so it becomes -9-4n! If you don't know like terms are anything variable that matches, for example, 7n & 3n! Along with -4 & -5!

Answer:

Dish A has a greater rate of change

Step-by-step explanation:

For this question, the information is given in two different forms, in words and a graph, so you need to understand what everything represents. For dish A the starting number, 5, is the initial value, and the amount it grows every day, 2, is the rate of change. For dish B the y-intercept, 5, is the initial value, and the slope, 0, is the rate of change. From this, you can see that both the initial values are the same, which means both answers on the right are incorrect. Also since 2 is greater than 0 the bottom left answer must be incorrect. This only leaves the top left answer.

Answer:

210 hits

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 30

Step 2: Solve for x hits

Remember that this is a prediction. According to the best line of fit, we would need 210 hits to get 30 home runs.

Answer:

The answer is 126.

Step-by-step explanation:

Height equals 4.5.

Perimeter is 11 + 3 + 11 + 3 = 28

The formula is s = ph

Perimeter times Height.

28 time 4.5 is 126.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangular surface. Then the lateral surface area is 192 square ft.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangular surface.

The dimensions of the rectangular prism are as;

Height = 4.5 ft

Length = 11 ft

Width = 3 ft

Then the lateral surface area will be

[tex]\rm lateral\ surface\ area = area\ of \ each \ face\\\\lateral\ surface\ area = 2*(4.5*11 + 11*3 + 3*4.5)\\\\lateral\ surface\ area = 2*(49.5 + 33+13.5)\\\\lateral\ surface\ area = 2*96\\\\lateral\ surface\ area = 192[/tex]

Thus, the lateral surface area is 192 square ft.
