Answer:
a. 2:3, b. 25 students, c. 3:2
Step-by-step explanation:
a. 5 (total) - 2 (with glasses) = 3 (without glasses), making the ratio 2:3.
b. We can assign the total students with the variable x. 3:5=15:x, 75=3x, x=25. 25 total students.
c. 25 (total students) - 15 (without glasses) = 10 (with glasses). (10+5):(15-5) is 15:10, which, when simplified, equals to 3:2.

Marques is a waiter at a restaurant. Each day he works, Marques will make a
guaranteed wage of $25, however the additional amount that Marques earns from
tips depends on the number of tables he waits on that day. From past experience,
Marques noticed that he will get about $14 in tips for each table he waits on. How
much would Marques expect to earn in a day on which he waits on 17 tables? How
much would Marques expect to make in a day when waiting on t tables?
Answer:
Step-by-step explanation:
25- guaranteed
$14 on each table waited on
He waited on 17.
17x14= $238 tips
238+25= $263
1. Marques expects to earn $263 on 17 tables
2. He expects to make 25+14t per day.

Place the following steps in order to describe how to solve the following equation: 2(2x+3)-2=5
Answer:
0.25
Step-by-step explanation:
First, you distribute the equation.
2(2x+3)-2=5
4x+6-2=5
Then, you combine like terms.
4x+6-2=5
4x+4=5
Next, you subtract 4 from each side.
4x+4=5
4x+4-4=4x
5-4=1
4x=1
Finally, you divide each side by 4.
4x/4
1/4
(4x/4 you'd end up with x)
Answer: x=1/4
Find the value of X and Y
Answer:
x = 20 , y =43
Step-by-step explanation:
1- 7x-3 + 3x-17 = 180
10x = 200, x = 20
Y = 3x-17 x is 20 so Y=60-17=43

a.
What is the distance, d, in miles, that the train travels in t hours?
How many miles will it travel in 2.5 hours?
b.
112.5 miles in 2.5 hours
Answer:
11.25 miles in 2.5 hoursStep-by-step explanation:
speed × time = distance
45 × 2.5 = 112.5
45 is the speed
2.5 is the time
11.25 is the distance
The component form of a vector indicates the changes in x and y from the
starting point to the endpoint. What is the component form of this vector?
We will see that the component form of the given vector is <-8, 2>, so the correct option is D.
How to get the component form of the vector?For a vector with starting point (a, b) and endpoint (c, d), the component form is:
<c -a, d -b>
In this case, we can see that the starting point is (4, -1), and the endpoint is (-4, 1)
Then the component form of the vector is:
<-4 - 4, 1 - (-1) > = <-8, 2>
So the correct option is D.

There are two trips, but the distances are the same.
Trip #1: uphill, at 9 mph
Trip #2: downhill at 18 mph
Total round trip is 30 minutes.
Since he's going half the speed uphill, Trip #1 takes twice as long as Trip #2.
So if the time for Trip #2 is x, then the time for Trip #1 is 2x.
x + 2x = 30, so x=10
Trip #2 takes 10 minutes.
Trip #1 takes 20 minutes.
Trip #1: 20 minutes at 9 mph = 3 miles
Trip #2: 10 minutes at 18 mph = 3 miles
This means his school is 3 miles away.
If you want an equation to solve,
Let d = distance to school. We use d = r·t formula to set up that t = d/r
let t1 = time going to school and t2 = times going home
t1 + t2 = 30 and t1 = d/9 and t2 = d/18.
d/9 + d/18 = 0.5 (it's 0.5, because we need the time in hours)
mutiply both sides b 18
2d + d = 9
3d = 9
d = 3

Given that,
A curve has been shown we have to explain the behavior of the curve.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The curve is shown, where the vertical axis represents the height above the ground and the horizontal axis represents the time. Let's assume a plane of paper is flying, the plane getting a rise and then a certain down and again rise and down as according to the height of the plane.
Thus, the graph represents the relationship between height and time.
