2x +8=2(x + 4)
mutiply the bracket by 2
(2)(x)= 2x
(2)(4)= 8
2x+8= 2x+8
move 2x to the left side
sign changes from +2x to -2x
2x-2x+8= 2x-2x+8
0+8= 0+8
8= 8
Answer:
All real numbers
Answer:
There would be 6 boxes, each with 3 toys, 8 books and 9 crayons.
Step-by-step explanation:
Find the greatest common factor of 18, 48 and 54 (the toys, books and crayons).
18 = 2*3*3
48 = 2*2*2*2*3
54 = 2*3*3*3
All of them have at least one 2 and one 3.
The greatest common factor is 6 because 2*3 is 6.
There will be 6 boxes.
The number of each item is the total items divided by number of boxes.
18/6 = 3
48/6 = 8
54/6 = 9
There would be 3 toys, 8 books and 9 crayons in each box.
Answer: £3885.71
Step-by-step explanation:
Let x be salary

The lion runs 50 miles per hour which is 20 more than a house cat. 20 mph + house cat mph = 50 → house cat mph = 30mph
Answer:
y = -0.83x - 2
Step-by-step explanation:
Slope intercept form is y = mx+b.
M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.
Now we have: y = -0.83x + b
B represents the y-intercept. The y-intercept here is -2. So our final equation is:
y = -0.83x - 2
