Answer:
4
Step-by-step explanation:
calculate the sum 4*1 any expression is multiplied by 1 remains the same solution is 4
Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11
Answer:

Step-by-step explanation:
Answer:
No
Step-by-step explanation:
Let's use the Pythagorean Theorem. For those of you that don't know, it is 
.
11 is the bigger side in this case, so our formula would go like this: 
.
We now calculate to see if this is true.
25 + 36 
121
Therefore, the answer is wrong.
