Answer:
(a+b)/c
Step-by-step explanation:
a/c+b/c
since they have the same denominator you can add the numerator together
(a+b)/c
One “x” tile and five “1” cubes
Answer:
x = 9
Step-by-step explanation:
Perimeter = 2 * width + 2 * length
= 2*11 + 2(x + 5) = 50
2x + 10 + 22 = 50
2x = 50 - 10 - 22
2x = 18
x = 9
The perimeter:
40+35+16+16+125.7= 232.7 m
btw lowkey frustrating that they alternate between cm and m
Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":

Subtract y from both sides:

Now, substitute "5-y" for "x" in the first equation:

Note that:


Cancel out like terms:

Subtract 25 from both sides:

Divide both sides by -10

Now, substitute this value back into either of the equations to solve for x.

Add 15/2 to both sides:

Now, find the difference:
