Answer: y = 1.125x
Step-by-step explanation:
Divide the amount in dollars by the number of euros.
9/8 = 1.125
45/40 = 1.125
Since the constant change is 1.125, the input the 1.125 into the formula y=kx for k to get the equation y = 1.125x

A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45. Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42. What is the value of each grocery coupon and each drug store coupon?
Answer:
The value of each grocery store coupon is $6
Then the value of each drugstore coupon is $3.
Step-by-step explanation:
Let's define:
G = value of a grocery store coupon.
D = value of a drugstore coupon.
We know that:
"A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45"
We can write this as:
3*G + 7*D = $45
And we also know that:
"Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42"
We can write this as:
3*G + 6*D = $42
Then we have the system of equations:
3*G + 7*D = $45
3*G + 6*D = $42
To solve this, we can isolate the term "3*G" in one of the equations (because it appears on both of them)
Let's isolate it on the second equation:
3*G = $42 - 6*D
Now let's replace this on the first equation:
($42 - 6*D) + 7*D = $45
$42 + D = $45
D = $45 - $42 = $3
Then the value of each drugstore coupon is $3.
And we also have the relation:
3*G = $42 - 6*D
We can just replace the value of D to get:
3*G = $42 - 6*$3 = $42 - $24 = $18
G = $18/3 = $6
The value of each grocery store coupon is $6

Step-by-step explanation:
A map has the scale of 1 inch = 50 miles. if two cities are 1 inch apart on the map how many miles separate the cities?
Answer: 175
Step-by-step explanation:
To determine the actual distance using the map scale of 1 inch = 50 miles, you would multiply the number of inches shown on the map by 50.
For this problem: 3 1/2 • 50 = 7/2 • 50 = 175 miles
The two cities are 175 miles apart.

(ax + by + cz)/(a + b + c)Step-by-step explanation:
Average = Sum / NumberIn terms of the scores we calculate the sum as:
ax + by + czThe number is the sum of the frequencies:
a + b + cMean average score is:
(ax + by + cz)/(a + b + c)4,5,10,8,4,8,7,6 range
Answer:
10-4=6
Step-by-step explanation:
The range is the difference between the biggest and smallest number. In this case, 10 is the biggest number and 4 is the smallest. So we do 10-4, which gives us 6, so 6 is the range.

Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
Y= -2x+3
2x+y=7
A. Parallel
B. Perpendicular
C. Neither
Answer:
A
Step-by-step explanation:
Because the have the same slope.
The second equation solving for y is:
Y= -2x+7.
Both equations have the same slope of -2
Answer:
Parallel
Step-by-step explanation:
If lines have the same slope, then they are parallel. If lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If neither one of those statements are true, then the answer is neither.
1) First, find the slope of the first equation. [tex]y = -2x + 3[/tex] is already in [tex]y = mx + b[/tex] format, or slope-intercept form. The [tex]m[/tex], or the coefficient of the x term, represents the slope. Thus, by looking at the equation, -2 is the slope of [tex]y = -2x + 3[/tex].
2) Second, find the slope of the second equation. [tex]2x + y = 7[/tex] is in standard format, but we can change it to slope-intercept format by isolating the y like so (just subtract both sides by 2x):
[tex]2x + y = 7 \\y = -2x + 7[/tex]
Now that it is in slope-intercept form, we can look at the coefficient of the x term, or [tex]m[/tex], to find the slope. That number is -2, thus the slope of [tex]2x + y = 7[/tex] is -2.
3) We found out that the slopes of both equations are -2. Thus, since they share the same slope, the lines are parallel.

Question 1 answer: A:40
You can get this by adding 16 to 24 to figure out what number is the best solution, and by doing this you get 40. If you want to check your work you can always do 40-16 or 40-24 to make sure it checks out.
Question 2 answer: D:1875
You can get this by multiplying 75 by 25 to get your answer. This is probably the easiest way to get an answer.

To complete the square on the left side of the equation x2 - 6x = 9,
you must subtract the number 9 from both sides.
Answer:
True
Step-by-step explanation:
[tex]x^{2} -6x=9[/tex]
subtract [tex]9[/tex] from both sides
[tex]x^{2} -6x-9[/tex]
plz mark me brainliest. ;)
what equations are true values of x?
Answer:
10 - 9 + 12x = 4x - 9 + 8x
x - 6 = 6 - x
1/2 (6x + 5) = 3x + 2.5

10. Jacob ran at a rate of 7 miles per hour. At this rate, how far does he run in 30 minutes?
Answer: Jakob will run 3 1/2 miles in 30 min
Step-by-step explanation: you need to take 7 in half because half of an hpur is 30 minutes so half of seven is 3 1/2 so that is the answer
Answer:
3.5 miles
Step-by-step explanation:
1 hour = 60 minutes
Proportions:
7 miles = 60 minutes
J miles = 30 minutes
J = 7*30/60
J = 3.5 miles
The radius of the front wheel of Monica's bicycle is 1 foot. About how far has Monica traveled after the wheel has made 100 revolutions? (use 3.14 for pi)
Answer:
Distance travel by Monica = 628 ft
Step-by-step explanation:
Given:
Radius of whee l = 1 ft
Number of revolution = 100
Find:
Distance travel by Monica
Computation:
Distance travel by Monica = 100[Circumference of wheel]
Distance travel by Monica = 100[2πr]
Distance travel by Monica = 100[2(3.14)(1)]
Distance travel by Monica = 100[6.28]
Distance travel by Monica = 628 ft
