Step-by-step explanation: TS 5 15 8 36
L = W + 10 cm
Perimeter = 2(L + W)
Perimeter = 70 = 2(W +10 +W)
70/2 = 2(W +10 +W) / 2
35 = (W +10 +W)
35 = 2W +10
35 - 10 = 2W +10 - 10
25 = 2W
25/2 = 2W/2
25/2 cm = W W = ?? cm
L = W + 10 cm
L = 25/2 + 10 cm L = ?? cm
Answer:
x ≤ 6 and x ≥ 2
Step-by-step explanation:
For now, we will start with doing each problem at a time. Here is your equation:
2x - 4 ≤ 8
First, you want to get the variable by itself. So, you add 4 to both sides. It will look like this:
2x - 4 ≤ 8
+ 4 + 4
The four being added on the left side cancels out, and you add 4 to 8. Now, it should look like this:
2x ≤ 12
Next, you want the x by itself. So, you would divide both sides by 2.
2x ≤ 12
/2 /2
2 divided by 2 cancels out, and 12 divided by 2 equals 6. Now, you have a final answer of:
x ≤ 6
But, you now have to do the other one!
Here is what you start off with:
x + 5 ≥ 7
First, you want the variable side by itself. So, you subtract 5 from both sides.
x + 5 ≥ 7
- 5 -5
Now, you have this:
x ≥ 2
Because the variable is already by itself, you don't need to do any more division and this is you final answer. Now put both answers you got together which equals:
x ≤ 6 and x ≥ 2
Answer:
x = -7
Step-by-step explanation:
41 + 76 + x + 70 = 180
x + 187 = 180
x = 180 - 187
x = -7
6 because if you multiply 2/3 by 6 it will give 4
