Answer:
First you would have to combine the numbers that are the same, so combine all the X's and the other numbers, with out a variable (without an X). The numbers with X are 2x and -4x, so you add them, you should have 2x (2+ (-4)= 2) your equation should look like this : 2x + 36 - 10= 10
Next you need to combine the other numbers, 36 and -10, add them, and you should get 26. Your problem should look like this 2x+26=10
Next you will need to subtract 26 from each side, what you do to one side of the equal sign you must do to the other. Your problem should look like this : 2x=-16
To find X you have to get X alone, so you have to divide how many x's there are, 2, so divide both sides by 2 (rembering that what you do to one side you must do to the other). So you should have x= -8

Four friends administered a bake sale table for a day. They made a total of $376.35 over the course of the day. Determined to give everyone an equal share of the money, each friend received $94.0875.
A. This statement makes sense. Dividing 376.35 by 4 results in 94.0875.
B. This statement does not make sense. Money values must be rounded to the nearest dollar. Each friend should receive $94.
C. This statement does not make sense. Money values must be rounded to the nearest cent. Each friend should receive $94.08.
D. This statement does not make sense. Dividing 376.35 by 4 results in 91.8375. Each friend should receive $91.8375 instead.
Answer:
c
Step-by-step explanation:
$376.35 / 4 does equal to $94.0875 but when it comes to money, it should be rounded to the nearest cent being $94 and .08 cents.

A parallelogram has a base of 10 centimeters and a height of 4 centimeters. What is the area of the parallelogram?
Step-by-step explanation:
Area of a parallelogram=base×height
=10×4
=40cm^2
The area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
It is given that:
A parallelogram has a base of 10 centimeters and a height of 4 centimeters.
As we know:
Area of a parallelogram = base×height
Area of a parallelogram = 10×4
Area of a parallelogram = 40 square cm
Thus, the area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.

Step-by-step explanation:
9x² + 6 = 12x
3x² + 2 = 4x
3x² − 4x + 2 = 0
Use quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)
x = [ 4 ± √(16 − 24) ] / 6
x = [ 4 ± √(-8) ] / 6
x = (4 ± 2i√2) / 6
x = (2 ± i√2) / 3

Charlie runs a screen printing company and is resetting a machine he uses to print triangular banners. He knows the amount of material he needs for the banner as well as the height of the triangle, but he needs to set the machine to a new measurement for the triangle’s base. To help Charlie determine the new measurement, rewrite the standard formula for the area of a triangle, A = bh, to solve for the base, b. Enter the correct answer in the box.
Answer:
b= 2a/h
Step-by-step explanation:
The new measurement can be obtained by the formula b = 2A/h the answer is b = 2A/h
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

find three consecutive even integers if the third is 8 less than twice the second
Answer:
8, 10, 12
Step-by-step explanation:
Because they are even there is a whole number x so that (1st)2x, (2nd) 2x+2, and (3rd)2x+4 are the 3 consecutive integers.
so
If the third is 8 less than twice the 2nd then:
3rd = 2 (2nd) - 8
2x + 4 = 2 (2x+2) - 8
2x + 4 = 4x + 4 - 8
2x + 4 = 4x - 4 Add 4 to each side
2x + 4 + 4 = 4x - 4 + 4
2x + 8 = 4x Subtract 2x from each side
2x - 2x + 8 = 4x - 2x
8 = 2x Divide each side by 2
8/2 = 2x/2
8/2 = x
4 = x
No we plug into our equations to find the integers.
2x = 2(4) = 8
2x + 2 = 2(4) + 2 = 8 + 2 = 10
2x + 4 = 2(4) + 4 = 8 + 4 = 12
So our integers are 8, 10, 12
solve for k 4.5+1.5k=18−3k
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4.5 + 1.5k = 18 - 3k}[/tex]
Move 3k to left hand side and change it's sign
Similarly, move 4.5 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{4.5k = 18 - 4.5}}[/tex]
Subtract 4.5 from 18
[tex] \longrightarrow{ \sf{4.5k = 13.5}}[/tex]
Divide both sides by 4.5
[tex] \longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}[/tex]
Calculate
[tex] \longrightarrow{ \sf{k = 3}}[/tex]
Hope I helped!
Best regards! :D
Answer:
k = 3
Step-by-step explanation:
Subtract 4.5 from both sides:
4.5 + 1.5k = 18 - 3k
-4.5 -4.5
1.5k = 13.5 -3k
Subtract -3k from both sides:
1.5k = 13.5 - 3k
+3k +3k
4.5k = 13.5
Now simplify:
4.5k = 13.5
k = 3

Please use method of substitution numbers 9;10;11;12
Answer:
1. x = 1, y = 2.
12. x = 1, y = -3.
Step-by-step explanation:
I won't do all these for you, just the first and the last. The method is similar for all 12.
1.
y = x + 1
x + y = 3
Substitute y = x + 1 into the second equation:
x + y = 3 so:
x + (x + 1) = 3
2x + 1 = 3
2x + 1 -1 = 3 - 1
2x = 2
x = 1.
Now substitute x = 1 into the first equation to get the value of y:
y = x + 1
y = 1 + 1
y = 2.
12.
4x = y + 7
3x + 4y + 9 = 0
Solve for y in the first equation:
4x = y + 7 Subtract 7 from both sides of the equation:
4x - 7 = y + 7 - 7
y = 4x - 7.
Now substitute y = 4x - 7 in the second equation:
3x + 4y + 9 = 0 so:
3x + 4(4x - 7) + 9 = 0
3x + 16x - 28 + 9 = 0
19x - 19 = 0
19x - 19 + 19 = 0 + 19
19x = 19
x = 19/19 = 1.
Now substitute x = 1 in the first equation:
4x = y + 7
4*1 = y + 7 Subtract 7 from both sides of the equation:
4 - 7 = y + 7 - 7
-3 = y.
