Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.
Write the thing spaced out:
4a <u>-5b</u> +6ab <u>-8b</u> -3a
The signs (+,-) are assigned to the numbers it is in front of.
We minus the "like" terms:
4a - 3a = 1a
<u>-5b - 8b = -13b
</u>+6ab = +6ab
Put them all together:
1a - 13b + 6ab
The answer for, "4a - 5b + 6ab - 8b - 3a" = "1a - 13b + 6ab"
Well, two dollars look like this: 2.00 and two dimes look like this: 0.20. the difference between them is 1.8 and there is if you already have 2 dimes then it would take 18 more dimes to get to 2 dollars. this is all i can think of please rate as brainliest and hope this helps :)<span>
