Answer:
x = 8 and y = 21
Step-by-step explanation:
3y + 27 = 90 so 3y = 90 -27 which is 63 and to get y you divide 63 by 3 to get 21
Angles on a straight line add up to 180 so 180 = x + 90 + 8x + 18
Then you minus 90 from 180 to get 90 = x + 8x + 18 which simplifies to 90 = 9x + 18
Then you minus 18 from 90to get 72 = 9x
Then divide 72 by 9 to get x = 8

Find f ( 6)
Answers
Answer:
so substitute x with 6
y = 4 + 36 + 1
so y or f(x) would = 41
Answer:
f(6) = 109
Step-by-step explanation:
Given polynomial:
f(x) = 2x2 + 6x + 1To Find:
f(6)Solution:
Here,in order to find f(6), substitute x = 6 onto the polynomial given:
f(x) = 2x^2 + 6x + 1f(6) = 2(6)^2 + 6(6) +1Now Simplify using PEMDAS rule.
f(6) = 2(36)+36+1f(6) = 72+36+1f(6) = 108+1f(6) = 109Hence, f(6) will be 109.

Savannah decides to download some new music. she downloaded 5 albums and 7 singles, and his total was $71. The next day she purchased more music from the same retailer and downloaded 3 more albums and 6 singles for a total of $48.
Assuming that all albums and singles are the same prices, how much did she spend on each album and each single? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.
Answers
Answer:
Step-by-step explanation:
downloaded= 5 albums and 7 singles and total price is $71
Know,
album + singles = 5+7= 12
∴ price÷ from total of albums and singles
$71÷12=$5.92
per album = $5.92
per single = $5.92
Next day;
3+6=9
total price =$48
⇒ =$48÷9 = $5.3
per album= $5.3
per album= $5.3
""""" I just try to Solve """"""
Answer: Singles are $3/each and albums are $10 each.
Step-by-step explanation:
Let A and S represent the number of Albums and Singles, respectively.
We are told that:
5A + 7S = $71
and also that:
3A + 6S = $48
We have two equations and 2 unknowns. Use elimination to find the price of one and then that will tell us the price of the other. I'll choose to eliminate the A:
5A + 7S = $71
3A + 6S = $48
We can do the elimination in one of 2 ways:
1) Solve one of the equations for A or S, and substitute it in the other:
3A + 6S = $48
3A = $48 - 6S
A = ($48 - 6S)/3
Now use this definition of A in the first equation:
5A + 7S = $71
5(($48 - 6S)/3) + 7S = $71
5(($48 - 6S)/3) + 7S = $71
$80 - 10S + 7S = $71
-3S = - 9
S = $3
Now we can find A:
5A + 7S = $71
5A + 7(3) = $71
5A + 21 = $71
A = $10
======
2) We could also modify one of the equations and then subtract to eliminate a variable:
5A + 7S = $71
3A + 6S = $48
Let's multiply the second equation by -(5/3):
-(5/3)*(3A + 6S = $48)
-5A - 10S = -90
Now add this to the first equation:
5A + 7S = $71
-5A - 10S = -80
- 3S = - 9
S = $3 and therefore A = $10

Given that,
Lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and the measure of angle 7 .
The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
here,
From the figure,
∠1 = ∠5
4x - 30 = 2x + 50
2x = 80
x = 40
Now,
∠ 1 = 4 [40] - 30
∠1 = 130° = ∠5
∠7 = 180 - ∠5
∠7 = 180 - 130 = 40°
Thus, the required measure of the angle 1 and 7 is given as 130° and 40° respectively.

Step-by-step explanation:
3(x - 4) = 11x
Expand the brackets:
3x - 12 = 11x
Subtract 3x from both sides to isolate the -12:
3x - 12 = 11x
3x - 3x - 12 = 11x - 3x
-12 = 8x
8x = -12
Divide both sides by 8:
[tex]\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\[/tex]
Simplify fraction:

Answers
Answer:
15 stones
Step-by-step explanation:
1) It is easier to convert to one unit. So i chose to convert everything to inches.
1 foot = 12 inches
10 feet = 120 inches
2) we then simply divide the size of the stones to see how much we need to cover the path
120/8 = 15 stones
