A) Solve 3x+6y=24 for x.
Subtracting 6y from both sides, we get
3x+6y-6y=24-6y
3x = -6y+24
Dividing both sides by 3, we get
x= -2y + 8
b) Solve 24−3x=6y for x.
Subtracting 24 from both sides, we get
24-24−3x=6y-24
-3x = 6y -24.
Dividing both sides by -3, we get
x= -2y + 8.
c) Solve 6y=24−3x for y in terms of x.
Dividing both side by 6.
y= 
d) Solve 24−6y=3x for x in terms of y.
Dividing both sides by 3, we get
8 - 2y = x.
x = -2y +8
<h3>Therefore, x=-2x+8 and
</h3>
Answer: 172 square meter square
Step-by-step explanation:
Area of Rectangular prism is given as :
A = 2 (wl + hl + hw)
Where :
w = width
h = height
l = length
Calculating the area of rectangular prism given , the shape given is divided into six segments , each segment is a triangle , all we need to do is to find the area of each segment and add.
Area of the first segment = 7 x 8 = 56 ( there are 7 boxes horizontally and 8 boxes vertically)
second segment = 2 x 8 = 16
third segment = 7 x 8 = 56
fourth = 2 x 8 = 16
fifth = 2 x 7 = 14
sixth segment = 2 x 7 = 14
Therefore , area of the rectangular prism will be
A = 56 + 16 +56 + 16 + 14 + 14
A = 172
Answer:
A = 30
Step-by-step explanation:
x = 5
y = 10
A = xy - 20
substitute 5 and 10 in the place of x and y
(5*10) - 20
50 - 20
30
A = 30
Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.
