Answer:
B: $90.
Step-by-step explanation:
The expression for this problem can be represented as
Total Cost = $44 + 2c
Since one chair costs $23, the total cost would be:
Total Cost = $44 + 2($23)
2 × 23 = 46
Total Cost = $44 + $46 = $90
The total cost is $90, choice B.

1 . First we will write the term having highest degree and then move to lowest degree,
→ 7 (y -5 x)² + x -3 x+2+5
2. Adding and subtracting like terms
→7 (y -5 x)² - 2 x+7
Expanding the term in brackets
→ 7(y² + 25 x² -10 x y) - 2 x + 7
Use distributive property
→ 7 y² + 175 x² -70 x y -2 x +7→[Wrote the terms from highest degree to lowest degree]

Determine which of the lines, if any, are parallel. Explain.
Line a: 4y +x=8
Line b: 2y + x = 4
Line c: 2y = -3x + 6
; The slopes are
Answer:
Parallel lines have same slope but different y-intercept
None of the given equations have same slope. Therefore lines are not parallel.
Step-by-step explanation:
Slope of Line a: 4y +x=8 is -1/4
Slope of Line b: 2y + x = 4 is -1/2
Slope of Line c: 2y = -3x + 6 is -3/2
Since the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that, the lines are.
Line a: 4y +x=8
Line b: 2y + x = 4
Line c: 2y = -3x + 6
Line a,
4y +x=8
4y= -x+8
y=-1/4x+2
Compare the given equation with the standard equation, y=mx+c in order to find the value of slope(m).
The slope of line a is -1/4.
Line b:
2y + x = 4
2y=-x+4
y= -1/2x+2
The slope of line b is -1/2.
Line c:
2y = -3x + 6
y= -3/2x+3
The slope of line c is -3/2
The slopes of the line 4y +x=8, 2y + x = 4 and 2y = -3x + 6 will be -1/4, -1/2 and -3/2 respectively.
Thus, if the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.

Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 5 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Answer:
2 hours 15 minutes
Step-by-step explanation:
Given that :
Ben's speed = 3 mi/hr
One and half hours after Ben leaves = 1.5 hours
Ben's distance = 3 mi/hr * 1.5 = 4.5 miles
Amanda's speed = 5 mi/hr
Time taken before Amanda catches up:
Let time taken = x
Distance = speed * time
Ben's distance = Amanda's distance
4.5 mi + (3 * x) = 5 * x
4.5 + 3x = 5x
4.5 = 5x - 3x
4.5 = 2x
x = 4.5 / 2
x = 2.25 hours
Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes
It would take Amanda 2.25 hours to catch up with Ben
Speed is the ratio of distance to time. It is given by:
Speed = distance/time
Given that Ben covers a distance d at time t, hence:
3 = d/t
d = 3t
Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5
5 = d/(t - 1.5)
d = 5t - 7.5
Since they catch up, hence:
3t = 5t - 7.5
2t = 7.5
t = 3.75 hours
Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours
Hence it would take Amanda 2.25 hours to catch up with Ben.

What is the solution to the equation 3X + 27 = -2x + 18
Answer:
-9/5 or -1.8
Step-by-step explanation:
3x+27=-2x+18 add 2x to both side
5x+27=18 minus 27 from both side
5x=-9 divide 5
x=-9/5, in decimal form=-1.8
Answer:-9/5
Step-by-step explanation:
3x + 27 = -2x + 18
-27 -27
-3x = -2x - 9
+2x +2x
5x = -9
5x/5 = -9/5

Answer:
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°
the answer Part 1) is x=124°
Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°
the answer Part 2) is y=44°

Tim saw that a pair of $200 dollar jeans had been marked down by 20%. He told his friend that if you took the new price of the jeans and increased that value by 20%, the jeans would return to the original price of $200. is he correct or no?
Hey there!
The answer is no, they would not return to the original price of $200.
This is because when you decrease 200 by 20%, you get 160. Then, if you increase 160 by 20%, you get 192. This is because 20% of 200 and 20% of 160 is different.

Pythagorean theorem
Answer: The area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. Quote the actual definition of the Pythagorean theorem.
Pythagorean theorem
in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.
This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.
we only use Pythagorean theorem to find the length of the missing side of a right angled triangle only.
