Answer:
The mistake happens in the 4th line.
Step-by-step explanation:
The first 3 lines are correct until the 4th line which is 2=6x. This is wrong. If we go back a line to the third line, it is 22=-20+6x. The part that was wrong was that they subtracted 20 from 22 to get 2. We are supposed to add 20 to each side because the -20 is negative. So the 4th line should be 42=6x. Then, we know that 6 times 7 is 42, so x is equal to 7.
22 + 53x + x = -20 + 60x
22 + 54x = -20 + 60x
22 = -20 + 6x
42 = 6x
x = 7

What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.
Answers
Answer:
C
Step-by-step explanation:
The degrees of a triangle add up to 180.
Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.
Angle A is equal to sinA=1/2.
sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.
90-30=60.
That leaves you with 60 degrees for angle B.

{45x+6y=15-x+18y=11 is..........................
Answers
Answer:
Step-by-step explanation:
45x+6y=15
-x+18y = 11
let's use elimination, the other way is by substitution, either way works but, it looks to me like elimination would be easy with the 'y'
3(45x+6y=15)
135x + 18y = 45 ( subtract 2nd eq. from 1st )
-( -x+18y = 11 )
136x +0y =34
x = 34 /136
x = 1 /4
there is X
plug that back into either of the 1st or 2nd equations to solve for y
- 1/4 + 18 y = 11
18y = 11 1/4
18y = 45/4
y = 45/4 * 1/18
y = 45/ 72

After a shipwreck, Sam is stranded on a desert island. He needs to build a shelter, so he
makes an axe using materials from the wreckage and starts cutting down trees.
There is a proportional relationship between the number of days Sam is stranded on the
island, x, and the total number of trees he cuts downy
Answers
The constant of proportionality is gotten from the graph to be 5
How to solve for constant of proportionalityThe complete part of the question is in the attached image which is a graph.
The graph has a positive slope, which implies a direct proportionality
hence we have that the number of trees is directly proportional to the number of days spent.
Let t represent the number of tress, d represent the number of days, and k constant of proportionality
The relationship is expressed mathematically as:
t ∝ d
t = kd
using any arbitrary point from the y axis ( t ) and tracing to the x axis ( d ). We have t = 5 and d = 1. substituting the values gives
5 = k* 1
Therefore
k = 5
The constant of proportionality is 5

A sine curve with a period of 8, an amplitude of 2, a left phase shift of /3, and a vertical translation down 5 units.
Answers
Answer:
[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]
Step-by-step explanation:
The standard form for a sinusoidal function is given by:
y = Asin[B(x - C)] + D
Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation
Given:
A = 2, D = -5 (down), C = -3 (left).
8 = 2π/B; B = π/4
Therefore:
[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Lena drive 696 miles in 12 hours. At the the same rate, how long would it take her to drive 522 miles?
Answers
Answer:
It would take Lena 9 hours.
Step-by-step explanation:
Looking at the problem I can do 696/12 to get the number of miles per hour she is traveling which is 58. With this number, I can take 522/58 to get 9 hours.
Answer:
Step-by-step explanation:
Remark
The best way to do this is to set up a proportion. It can be done by using d = r * t twice, but a more direct way is to use the proportion.
Formula
distance1 / time1 = distance2 / time2
Givens
distance1 = 696 miles
time1 = 12 hours
distance2 = 522 miles
time2 = x
Solution
696/12 = 522/x Cross multiply
696 * x = 522* 12 Combine the right
696 * x = 6264 Divide by 696
x = 6264/696
x = 9 miles

Answers
Answer:
( -1.5 , 1 )
Step-by-step explanation:
Hello There!
When dilating a point we divide or multiply the coordinates by whatever the scale factor is
Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2
Preimage coordinates - ( -3 , 2 )
-3/2=-1.5 or -3/5
2/2=1
Dilated image coordinates ( -1.5 , 1 )

no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?
Answers
Answer:
$5150
Step-by-step explanation:
Given data
Principal=$4000
Rate=5.75%
Time= 5 years
The expression for the balance on simple interest is
A=P(1+rt)
substitute
A=4000(1+0.0575*5)
A=4000(1+0.2875)
A=4000X(1.2875)
A=$5150
Hence the balance is $5150
