Answer:
x*2=y+x= both
Step-by-step explanation:
y would be her sister age, you would have to multiply Marias age by 2 to get her sisters age since her sister is twice her age then you have to add them together to get the sum of both their ages.
Example: maria is 16
16*2=32+16=48
so the sum of both of their ages is 48 (JUST AN EXAMPLE)
(x + 12) - 3
x + 12 is the sum of x and 12
And if you subtract 3 it is three less than the sum
Hope this helps!
Answer:
Sorry for the sloppiness of the drawing
Step-by-step explanation:
The length of the first two sides of a triangle must be greater than the length of the last side. If the longest length were 18, the first two sides would be too short. 36-18=18, 18 is equal not greater than 18 which means the sum of the first two sides are too short.
That would be 5(3w + 13)
