Evaluate 7r- 15/8 when r= 3 and 8=5. I'm confused need help:)​

Answers

Answer 1
plug the values of r and 8 into the equation and solve it. so the equation you get is 7(3) - 15/5. that’s the same as 21-3, which is 18, so that’s the answer.

I have a bag containing red, green, blue, and white marbles and the ratio $\text{red}:\text{green}:\text{blue}:\text{white}$ is $2:2:5:7$. I have 304 marbles. How many blue marbles do I have?

Answers

Answer:

95

Step-by-step explanation:

Let 2x be how many red/green marbles there are,

let 5x be how many blue marbles there are, and

let 7x be how many white marbles there are.

2x + 2x + 5x + 7x = 304

16x = 304

x = 19

As 5x is defined as how many blue marbles there are, we could just plug x for 19:

5*19 = 95

I hope this helped, and if it did please consider giving me brainliest :)

Answer:

95

Step-by-step explanation:

Let r, g, b, w be the number of red, green, blue, and white marbles, respectively. Since r : g : b : w = 2 : 2 : 5 : 7, there is some value of x for which r = 2 x, g = 2x, b = 5x, and w = 7x. Then, we have

                                      304 = r + g + b + w

                                      = (2x) + (2x) + (5x) + (7x)  

                                                              = 16x

Dividing both sides of 16x = 304 by 16 gives x=19. This gives us r = 38, g = 38, b = 95, w = 133, so I have 95 blue marbles.

Which equation shows a proportional relationship between x and y a) y=2×+1 b) y+4×=8 c) y=5×

Answers

If our options to answer this from are:
• y=2x+1
• y+4x=8
• y=5x
Then to find a proportional relationship represented by an equation, we look for an option where its y=#x, so we can REMOVE option B. And so your answer is C. as y=5x is a proportional relationship between x and y since its not adding or subtracting a number from either y or x.

Henry's Jewelry Store receives a shipment of 500 jewelry pieces, but 15 pieces are damaged. At this rate, if Henry's Jewelry Store places an order for 5,500 jewelry pieces, how many should they expect to be damaged? They should expect pieces of jewelry to be damaged.

Answers

Answer:

They should expect 165 damaged pieces in 5500 jewelry pieces

Step-by-step explanation:

The first thing we need to do is to get some metrics to measure the rate at which the damaged jewelry is seen.

We can use 15 pieces of jewelry that are damaged for every 500 ordered.

Once this is done, we can then use this to estimate how many pieces of jewelry are damaged if 5,500 are ordered.

We now need to know how many sets of 500 pieces of Jewelry are in 5,500.

This is 5,500/ 500 = 11 sets

Therefore, all 11 sets will have 15 damaged pieces of jewelry each. The total number of damaged jewelry pieces will be 15 X 11 = 165 damaged pieces

​The radius of the circle shown below is 3 inches.
​What is the area of this circle, in square inches?

Answers

Answer:

the area = 28.27 or you can write the answer out as 28.2744 or also 28.27433

Step-by-step explanation:

start with what we know. the formula for solving this is A=pi R squared

so, area= pi (3.1416)

then, multiply that by the radius given, which is 3.

So, 9.4248 × 3 = 28.2744 square inches

or 28.27 sq.in.

Graph a line with a slope of -5 that contains the point (-3,-4)

Answers

We want to graph a line with a slope of -5 that contains the point (-3, -4), the graph can be seen at the end.

Getting the equation:

We first need to get the equation of the line that we must graph.

The general line equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we know that the slope must be -5, so we have:

y = -5*x + b

And we know that it must contain the point (-3, -4), then we can replace these values for x and y in the equation and solve it for b:

-4 = -5*-3 + b

-4 = 15 + b

-4 - 15 = b

-19 = b

Then the linear equation is:

y = -5*x - 19

To graph this you just need to find two points on the line and then connect them with a line, we already know one (-3, -4). To get another we can evaluate the equation in any value of x, for example with x = 0 we get:

y = -5*0 - 19

y = -19

Then the other point is (0, -19)

With these two points you will get the graph below:
