Question 4
The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:
[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]
Distrubute -3 into the parentheses
[tex]-12x+12=-15x-24[/tex]
Subtract both sides by 12
[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]
Add 15x to both sides
[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]
Question 5
The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:
[tex]10=16x+2[/tex]
Subtract both sides by 2
[tex]10-2=16x+2-2\\8=16x[/tex]
Divide both sides by 16
[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]
I hope this helps!

The sum of two numbers is 58. Twice the second
number subtracted to four times the first number is
28. Find the two numbers.
Answers
Answer:
Step-by-step explanation:
a+b=58 and 4a-2b=28 is the system of equations
solving the first for a, a=58-b, using this value for b in second equation is
4(58-b)-2b=28
232-4b-2b=28
232-6b=28
-6b=-204
b=34, and since a=58-b
a=58-34
a=24
So the two numbers are 24 and 34

A sales clerk sold 3 times as many T-shirts as hats last week. The number of belts she sold was 15 more than 1/4 the number of hats she sold. If she sold 288 hats, how many fewer belts than t-shirts did the clerk sell?
Answers
Answer:
777 fewer belts

Which theorem is the following?
"If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment"
Answers
Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then
[tex]AB + BC = 10[/tex]
Where
[tex]AB = BC[/tex] --- Perpendicular bisector
So, the equation becomes
[tex]AB + AB =10[/tex]
[tex]2AB =10[/tex]
[tex]AB = 5[/tex]
Recall: [tex]AB = BC[/tex]
[tex]AB = BC = 5[/tex]

S varies inversely as G. If S is 9 when G is 2.4, find S when G is 6. a) Write the variation. b) Find S when G is 6
Answers
Answer:
S = 21.6/G
S = 3.6
Step-by-step explanation:
Inverse variation:
y = k/x
For this problem:
S = k/G
We use the given values of S and G to find k.
9 = k/2.4
k = 9 * 2.4
k = 21.6
The equation is
S = 21.6/G
For G = 6,
S = 21.6/6
S = 3.6

1. How many triangle make a trapezoid
Answers
A trapezoid consists of two triangles.
A trapezoid does indeed contain two triangles within its structure. A trapezoid is a quadrilateral with one pair of parallel sides.
The other two sides, known as the legs, are not parallel and meet at a point. These legs, along with the two parallel sides, form two triangles within the trapezoid.
One triangle is formed by connecting the two legs and one of the parallel sides. The other triangle is formed by connecting the two legs and the other parallel side.
So, a trapezoid consists of two triangles.
