Answer:
I believe the answer would be 4.2
Step-by-step explanation:
Reason for this is because I divided 12.6 by 3 and got 4.2, then I added 4.2 + 4.2 and got 8.4, so then I added 4.2 to 8.4 and got 12.6. Hope this helps :)

4
and passes through (0, 7).
5
Answer:
D. y = -4/5x + 7
Step-by-step explanation:
y = -4/5x + b
7 = -4/5(0) + b
7 = 0 + b
7 = b
factorise B square minus 25
Answer: (b+5)(b-5)
Step-by-step explanation:
both b^2 and 25 are square numbers, so square root both of them to give b and 5, then put into brackets with a + and -

Two step equations word problems
The perimeter of a rectangle is 34 units. Its width is 6.5 units.
1. Write an equation to determine the length (l) of the rectangle.
2. Find the length of the rectangle.
Answer:
10.5 unitsStep-by-step explanation:
Given
Perimeter P = 34 unitsWidth w = 6.5 unitsLength l = ?Equation, in terms of l:
2(l + 6.5) = 34l + 6.5 = 17l = 17 - 6.5l = 10.5Answer:
Equation:6.5 + 6.5 + L +L =34
Answer: 10.5
Step-by-step explanation:
To find perimeter you need L+W+L+W. You have a width of 6.5. When you plug that into the equation you get 6.5 + 6.5+ L+L=34. Combine like terms (6.5 +6.5). That leaves you with 13 + 2L = 34. Now, you want to subtract 13 from both sides to isolate the L. You now have 2L = 21. Now you should divide everything by 2. 21/2 = 10.5

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?
Step-by-step explanation:
1.5x + 6-3= 4.5x- 2
1.5x+3=4.5x-2
we transposed
4.5x-1.5x= 3+2
3x= 5
we divide both sides by 3
3x/3= 5/3
x= 5/3
