You and a friend are doing math homework together you have to solve the equation 5X + 4X -68 equals 34 - 8X. Your friend arrives at the incorrect answer X equals -2 find the correct value of X then find the error your friend possibly be made
Answer:
the correct answer
x = 6
Step-by-step explanation:
5x+4x-68=34-8x, combine like terms
9x-68=34-8x, add 68 to both sides
9x=102-8x, add 8x to both sides
17x=102, divide both sides by 17
x=6
your friend's answer is the same work, but instead of adding 68 to both sides, it was subtracted from 34 giving a -34 instead of 102.
9x=-34-8x
17x= -34
x = -2

The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
-3n + 27
-3(27) = n
-3n = 27
-3 = 27n
Answer:
-3n=27
Step-by-step explanation:
The value of n is -9.
So we can represent this in an equation. We won't get that as a result if we multiply the following
-3n=27 Divide -3 by both sides.
n=-9
Answer:
The product of a number and negative three is twenty-seven.
-3n=27

Answer:
A, B, C, D, F . . . as written
Step-by-step explanation:
Any mixed number, fraction, or finite or repeating decimal is rational. The only one in your list that is irrational is E, which appears to be a non-repeating, non-terminating decimal.
__
Your B selection appears to be 11² = 121, an integer and a rational number.
If your B selection is supposed to be √11, then that number is irrational, as it is not the root of a perfect square.
E is irrational; B is rational as written, but irrational if it should be √11. All the others are rational.

Answer:
D)
Step-by-step explanation:
In slope-intercept form in order to find the perpendicular equation you change the sign and find its reciprocal.
So in the equation y= -3x+1, the opposite sign of - is + and the opposite of 3 is 1/3
At the end of the year, cars made in the current year are marked down to make room for next year's models. One particular model had a sticker price of $22,570 when it was new. It has just been marked down by 10%. What is the sale price of the vehicle?
Answer:
$20,313
Step-by-step explanation:
You're only reducing 10% of the cost so first you need to figure out what 10% of $22,570.
All you need to do is
22570×0.1=2,257
and then
22,570-2,257=20,313

A rectangle has a perimeter of 104 feet. If the
width of the rectangle is one more than twice its
length, determine the dimensions of the
rectangle.
Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35

Use any method to multiply (–14ab)(a + 3b – 4c).
Question 2 options:
A)
–14a2b – 42ab2 + 56c2
B)
14a2b + 42ab2 + 56abc
C)
–14a2b – 42ab2 + 56abc
D)
–14a2b – 42a2b2 + 56c
Answer:
-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer
Step-by-step explanation:
Expand the following:
-14 a b (a + 3 b - 4 c)
Hint: | Distribute -14 a b over a + 3 b - 4 c.
-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):
-14 a b a - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b a = -14 a^2 b:
-14 a^2 b - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b×3 b = -14 a b^2×3:
-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and 3 together.
-14×3 = -42:
-14 a^2 b + -42 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and -4 together.
-14 (-4) = 56:
Answer: -14 a^2 b - 42 a b^2 + 56 a b c

Brodie hires a technician to fix his air conditioning unit. The total cost includes $26.50 for parts and $50.00 per hour the technician works on the job.
Which equation can be used to find y, the total cost Brodie pays, given x represents the number of hours the technician works on the job?
y = 26.50x + 50
y = 50x + 26.50
y=26.50(x+50)
y=26.50x−50
Answer:
y = 50x + 26.50
Answer:
Y = $50x + $26.50
Step-by-step explanation:
$26.50 is the independent cost unaffected by hours put in.
Rate is $50 per hour.
X then is the hour count.
Thus,
Y = $50x + $26.50
