Answer:
2x+2y=x+5
(move the x next to the 2y)
= 2x+2y-x=5
(the x is negative because i moved it)
(collect the like terms)
= x+2y=5
(so the answer is...)
x+2y=5

Answer:
See below
Step-by-step explanation:
First, lets see how many feet of the original Eiffel tower (O) are represented in 1 foot of Caesar's tower model (M). We know that 1.5 foot is equal to 984 feet of the original, so we can say:
1.5 M = 984 O, this is our equivalence.
Now divide both sides by 1.5
1.5 M / 1.5 = 984 O / 1.5
1 M = 656 O
So, 1 foot of Cesar's Model is 684 feet of the original tower. We also know that 1 foot is equal to 12 inches, so we can say that 12 inches of Cesar Model (12 m) are equivalent to 656 feet of the original tower. So:
12 m = 656 O
If we divide both sides by 12:
m = 656/12 O
m = 56.67
So, 1 inch in Cesar's model represent 56.67 feet of the original Eiffel Tower.
Lets verify our result by multiplying 56.67 by 12 to get 1 feet and then by 1.5 to get the measure of the model:
56.67*12*1.5 = 984 feet, which is the height of the Eiffel tower.
Scale: 1 inch = 56.67 feet

Answer:
The correct answer is the first solution set.
Step-by-step explanation:
If we substitute -20 into the equation we get
-20+17≤-3
-3≤-3
So,the inequality is right.
We can check the second one
14+17≤-3
31≤3 The inequality is false.
We can check the last one
-20+17≤-3
-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.
If we substitude -21 into the equation we get
-21+17≤-3
-4≤-3
The inequality is false because -4 is not smaller than -3.
So,the right answer is the first solution set.
