Step-by-step explanation:
Lance is solving the equation 2(2x + 1) - (3x - 5) = 17. His steps are shown below: Step 1: 4x + 2 - (3x - 5) = 17 Step 2: 4x + 2 - 3x - 5 = 17 Step 3: x + 2 - 5 = 17 Step 4: x - 3 = 17 Did Lance make a mistake? If so, in which step did he make the mistake and what was his mistake?
Answer:
Lance made a mistake
His mistake was in step 2
Step-by-step explanation:
Yes, Lance made a mistake.
He made a mistake in step 2 of his solution.
The mistake he made was that he was supposed to open the bracket of -(3x-5) to give -3x + 5
The 5 is supposed to have a positive value and not a negative

y = 3x - 2
x - y = 4
Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4

A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?
Answer: The number of canned goods in 7th row = 64.
Step-by-step explanation:
The given numbers of canned goods in every row( starting from first ) is represented as
40 , 36, 32, ...
There is a common difference between numbers(d)= 4
∴ Its is an Arithmetic progression.
First term (a) = 40
nth term in A.P. : [tex]a(n)= a+(n-1)d[/tex]
7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64
So, the number of canned goods in 7th row = 64.

-9x + (?) =27 WILL GET BRAINLYIST
Answer:
-27
Step-by-step explanation:
Given expression:
-9(x + 3) = 27
Now use the open the bracket;
-9x - 27 = 27
Given -9x + (?) = 27
Comparing the two equations shows that the question mark corresponds to the value -27;
The solution is -27

SOMEONE PLEASE HELP I NEED THE SOLUTION TO ALL OF THESEE PLEASE HELP!!!!
Answer:
The answer is below
Step-by-step explanation:
Let's work it out slowly
A)
$18.79 + $2.11 - $1.92 + $17.28
- 18.79 + 2.11 + 17.28 = 38.18
- 38.18 - 1.92 = 36.26
Ans = $36.26
B)
$7.45 + $24.45 + $74.17 + $76.52
- 7.45 + 24.45 = 31.9
- 74.17 + 76.52 = 150.69
- 150.69 + 31.9 = 182.59
Ans = $182.59
C) $98.45 - $10.63 + $2.82 - $20.26
- 98.45 - 10.63 - 20.26 = 67.56
- 67.56 + 2.82 = 70.38
Ans = $70.38
Hope you understand

PLS HELP FAST if all three angles of a triangle are 60 degrees, what are the length of the side(s)?
Answer:
180

Use the diagram and the given angle measure to find the other three measures.
m∠1=143∘
m∠2=
m∠3=
m∠4=
Answer:
angle 2 = 37⁰
angle 3 = 153⁰
angle 4 = 37⁰
Step-by-step explanation:
I guess this refers to two intersecting lines which form 4 angles.
Angles 1 and 2 are supplementary angles whose sum is 180⁰.
Angle 1 + angle 2 = 180⁰
143⁰ + angle 2 = 180⁰
angle 2 = 180⁰ - 143⁰
angle 2 = 37⁰
Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.
Hope this helps...
Answer:
m∠1 = 143°
m∠2 = 37°
m∠3 = 143°
m∠4 = 37°

Answer:
A) true
B) false
c) true
d) true
Step-by-step explanation:
A) angles 7 and 6 are vertical angles, which means they're equal.
so, A is True.
B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False
C) angle 7 is equal to angle 3, which is supplementary to angle 1.
so, 55 + angle 1 = 180
55 + angle1 = 180
subtract 55 from both sides of the equation
angle1 = 180 - 55
angle 1 = 125.
angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125
125 + 125 = 250
so, C is True
D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

Jason has applied to be a camp counselor for the summer. The job pays $9 per hour. The equation to represent Jason’s job is y = 9x, where x is the number of hours he works and y is the total amount he earns.
Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and pay as shown in the table below.
Tuesday
Thursday
Saturday
Hours worked
6
8
5
Amount paid
$52.50
$70.00
$43.75
Which statement best describes the hourly rates?
The two jobs pay the same hourly rate.
The comparison cannot be made with the information given.
Jason’s camp counselor job pays a higher hourly rate than Mia’s lifeguard job.
Jason’s camp counselor job pays a lower hourly rate than Mia’s lifeguard job.
Answer:
Jason's job pays a higher hourly rate than Mia's lifeguard job.
Step-by-step explanation:
It tells that Jason gets paid $9/hour
now divide each amount Mia makes by the number of hours each day and you get the same amount of $8.75/hour.
