A system of equations is shown.
2x + 2y = 24
X = 3y
What is the value of x + y?
Enter your response here: Only 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, -, -, and / are allowed in your answer.
Answers that are mixed numbers must be entered as an improper fraction or a decimal.
Answer:
x+y=12
Step-by-step explanation:
First, substitute 3y for the spots with x:
2(3y) + 2y = 24
6y+ 2y = 24
8y= 24
y= 3
Then sub in 3 in the y place:
x= 3(3)
x= 9
Then plug in the x and y values in the equation:
9 + 3 =12
Good Luck!!!

In the same way that other functions can be combined, a series of transformations can be combined into a single function. For example, this statement for the function S shows one way to represent the rotation of a point 270° counterclockwise about the origin followed by a translation 3 units to the left and 1 unit up: S(270, O)/<-3,1>(x, y) = (y – 3, -x + 1).
Write a function to represent each series of transformations:
rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis
reflection across the y-axis, then a translation a units to the right and b units up
translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
Answer:
"unit"

The scale of a map says that 6 cm represents 15 km.
What distance on the map represents an actual distance of 6 kilometers?
a) 0 3.6
b) 2.5
c) 0 2.4
d) 0.42
Answer:
Scale distance on map representation = 2.4 cm
Step-by-step explanation:
Given:
Scale factor [6 cm - 15 Km]
Actual distance = 6 km
Find:
Scale distance on map representation
Computation:
Scale distance on map representation = Actual distance[6cm / 15km]
Scale distance on map representation = 6km [6cm / 15km]
Scale distance on map representation = 36 / 15
Scale distance on map representation = 2.4 cm

Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue. If there are 3 silver rocks, how many space rocks does Kenzie have?a
Answer:
There were 36 space rocks in total.
Step-by-step explanation:
First, you need to find what fraction of the original rocks are silver.
If 2/3 are purple, then 1/3 of them are not.
If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.
2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.
So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.
This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.
So:
1/12r = 3
r = 36 silver rocks
There were 36 space rocks in total.
hope this helps :)
There are 600 apples on a tree and there are maggots in 3/5 of them. How many apples have maggots in them ?
Answer: 360
Step-by-step explanation:
1/5 of 600 is 120
Since we have to take 3/5 we simply multiply 120 by 3 to get 3/5
Thus meaning that the answer is 360 apples.

Find the value of x.
Answer:
x = 63
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 62 + 55 = 180
x + 117 = 180
x = 180 - 117
x = 63

Answer: 30
Step-by-step explanation:
You put the numbers from least to greatest. 27,28,28,29,29,29,30,30,30,31,31,31,33,34. Then the median would be 30 and 30. So then you would add the two numbers 30 + 30 then divide by 2. 60/2 and the answer would be 30. Hopefully that was helpful.
In the formula, l = a + (n - 1)d make d as the subject. Find d when l = 10, a = 2, n = 5.
Answer:
d=2
Step-by-step explanation:
l=a+(n-1) d
10=2+(5-1)d
10-2=4d
8=4d
d=2...
Answer:
2
Step-by-step explanation:
I = a + (n - 1)d
10 = 2 + (5 - 1)d
10 = 2 + 4d
10 - 2 = 4d
8 = 4d
d = 2

Find the critical value t for the confidence level c= 0.98 and sample size n=7.
Click the icon to view the t-distribution table.
=(Round to the nearest thousandth as needed.)
Answer:
The critical value is T = 3.143.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 7 - 1 = 6
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 3.143.
The critical value is T = 3.143.
Find the exact area of each circle
9514 1404 393
Answer:
225π ft²
Step-by-step explanation:
The area of the circle is given by the formula ...
A = πr²
The figure shows the radius (r) is 15 ft. Using that value, we find the area to be ...
A = π(15 ft)²
A = 225π ft² . . . . exact area of the circle
