Answer:
b = 2a + c
Step-by-step explanation:
Given
a = [tex]\frac{1}{2}[/tex] (b - c)
Multiply both sides by 2 to clear the fraction
2a = b - c ( add c to both sides )
2a + c = b
After the rearrangement, the equation as b the subject b = 2a + c.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given that the equation;
a = 1/2 ( b - c)
Rearranging the equation;
a = 1/2 ( b - c)
Multiplying 1/2 to the the terms of brackets,
a = (b/2) - (c/2)
b/2 = a + (c/2)
Divide by 2 on both sides of the equation;
b = 2a + c
Therefore, the equation as b the subject b = 2a + c.

A system of linear equations is given as x + 3y = 36 and 4x + 5y = 9. Which of the following is a possible first step when solving by substitution? *
1 point
Rewrite the first equation as x = 36 – 3y.
Rewrite the first equation as y = 1/3x + 12.
Rewrite the second equation as x = 9 – 5/4y .
Rewrite the second equation as y = 9 + 4x.
Answer:
Rewrite the first equation as x = 36 – 3y.
Step-by-step explanation:
x + 3y = 36 (1)
4x + 5y = 9 (2)
Using substitution method
From (1)
x = 36 - 3y
Substitute x = 36 - 3y into (2)
4x + 5y = 9
4(36 - 3y) + 5y = 9
144 - 12y + 5y = 9
- 12y + 5y = 9 - 144
-7y = -135
y = -135 / -7
y = 19.3
There is an error with the second equation, 4x + 5y can not be equal to 9
Nevertheless, the first step when solving by substitution is:
Rewrite the first equation as
x = 36 – 3y.

An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks. Combined sales totaled $4,770. How many lower-priced speaker docks did it sell?
Answer:
9
Step-by-step explanation:
Let us represent
Low priced = x
High priced = y
An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Combined sales totaled $4,770.
170x + 90y = $4770
Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks.
4x = y
Substitute 4x for y
170x + 90y = $4770
170x + 90(4x) = $4770
170x + 360x = $4770
530x = $4770
x = 4770/530
x = 9
The number of lower-priced speaker docks it sold was 9

If U = {all teachers), M = {mathematics teachers) and W = {teachers who are women), show on a Venn diagram the set of all mathematics teachers who are men.
Answer: See the diagram below
Specifically, refer to figure 4.
==========================================================
The set U is the universal set. It represents every teacher. Let's draw this as a rectangle. Divide the rectangle so that one portion represents female teachers, and the other represents male teachers. I'll use a vertical line to divide the universal set.
Now draw a circle such that one portion of the circle is in the "male teacher" region and the other portion of the circle is in the "female teacher" region. Lastly, shade the region inside the circle that is also in the male teacher region. The diagram below shows the step by step process.
Figure 1 is the rectangle representing the universal set, which in this case is the set of all teachers.
Figure 2 splits up set U into female teachers on the left and male teachers on the right.
Figure 3 adds a circle, set M, to represent all math teachers. This circle spans the male and female teacher regions, since we can have either male or female math teachers.
Figure 4 adds labels A,B,C,D such that
A = set of female teachers that don't teach mathB = set of female teachers that teach mathC = set of male teachers that teach math. This region is highlighted to answer the question your teacher provided.D = set of male teachers that don't teach mathThere are no gaps or overlaps between any of the A,B,C,D regions. We consider these regions to be mutually exclusive. If a person is in region B for instance, then they cannot be in any other region. This is assuming no person teaches more than one subject. Note how regions A,B,C,D completely fill the set U, and do so without any gaps or overlaps. So we can say that set U is partitioned into those four regions.

For a company picnic, Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup. Each paper cup holds 1 ounce. Later, Todd and Yuki learn that two other company employees completed exactly the same task. Question 1 Part A Write a numerical expression to find how many ounces of ketchup the four employees prepared.
Step-by-step explanation:
Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup.
Each paper cup holds 1 ounce
Todd = 30 * 1 = 30 ounces
Yuki = 27 * 1 = 27 ounces
Total ounces = 30 + 27
Later, Todd and Yuki learn that two other company employees completed exactly the same task.
Total ounces = 2 (30 + 27)
Answer:2(30+27)
Step-by-step explanation:
the other company is doing the same thing so you multiply by 2
and we have 30 and 27 so we use those numbers to make
2(30+27)

Find X, BA, AC, and BC of isosceles triangle BAC.
BA= 2x-5; AC = 3x -9;
BC = X-2
Answer:
BA = 3
AC = 3
BC = 2
x = 4
Step-by-step explanation:
Find x
BA and CA are equal Given
2x - 5 = 3x - 9
Subtract 2x from both sides
- 5 = 3x - 2x - 9
- 5 = x - 9
Add 9 to both sides.
- 5 + 9 = x - 9 + 9
4 = x
=========================
BA = 2x - 5
BA = 2*4 - 5
BA = 3
AC = 3x - 9
AC = 3*4 - 9
AC = 12 - 9
AC = 3
BC = x - 2
BC = 4 - 2
BC = 2
Summary
BA = 3AC = 3BC = 2x = 4Do the ratios 8:24, and 5:15 form a proportion

Opposite sides of parallelogram ABWC are equal.
Since point C bisects VW, VC=CW
And 3x+1=CW and CW=1/2 of VW

6x+2=7x-3
x=5
Then VW=7(5)-3=32

Find the surface
area of the
composite figure
shown.
15 ft.
square feet
15 ft.
(Include the base of
the green cube in your
calculation.)
15 ft.
HELP
Answer:
Step-by-step explanation:
We need to find 5 sides of the cube and 4 sides of the pyramid.
For the cube, each side's area is [tex]s^{2}[/tex] with s being the side length. Since there are 5 sides, it would be 5 x [tex]s^{2}[/tex]. s=15, so it would be 5 x 15 x 15, which is 75 x 15 which simplifies into 1125.
For the pyramid, we need to find the area of all 4 triangles. They are all the same triangle, each with a base of 15 and a height of 9. So one triangle's area is 9 x 15/2 = 67.5 --> Since there are 4 triangles, the area of all of them would be 67.5 x 4 which is 270.
1125 + 270 = 1395 cubic ft. (or [tex]ft^{3}[/tex])
