Answer:

Multiply.

Step-by-step explanation:

2 * 15 = 30

5 * 37.50 = 187.5

6 * 45 = 270

8 * 60 = 480

480 + 270 = 750

187.5 + 30 = 217.5.

Answer:

15.4

Step-by-step explanation:

What i did was i did it in standard form. But, what i did was the 7 x 2 which is 14 then carried the 1 to the ones place. Then, i did 7x2 + 1 to get 15. Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

Heres the work:

Answer:

We are given that:

variables x and y vary directly, this means that:

y = kx where k is the constant of proportionality

Now, we are also given that:

y = 45 at x = 40.

We will use these values and substitute in the above relation to get k as follows:

y = kx

45 = 40k

k = 45/40 = 9/8 = 1.125

Based on the above calculations, the equation that relates x and y is:

y = 1.125x

Answer:

1/5

Step-by-step explanation:

The mixed number for the  given case can be obtained as 10²/₅.

A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.

Suppose the number be x.

Then, the following equation can be written for information given as,

1/4(x - 3.2) = 1.8

It can be solved as,

x - 3.2 = 1.8 × 4

⇒ x = 7.2 + 3.2 = 10.4

It can be written in mixed form as below,

10.4 = 10 + 4/10

⇒ 10 + 2/5 = 10²/₅

Hence, the required number is 10²/₅.

Step-by-step explanation:

simple: it will become 3 times 1/9 = 1/9+1/9+1/9 = 3/9 , which will eventually be 1/3, when both numerator and denominator will be divided by thier common factor that is 3

D

when you're doing a perpendicular line, you want the exact opposite of your original.

take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.

With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so

First, make it negative

Next, flip it around.

You get -7/2 as your slope perpendicular to your original line.

For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.

For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.

Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.

-3=4(5)+b

Now, simplify

-3=20+b

-23=b

Your example equation is now y=4x-23

Answer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
