Answer:
x=10
Step-by-step explanation:
90+3x+10+3x+20=180
-90 -10 -20 -120
combine like terms
6x=60
x=10
<span>Given:
AB = x + 16
BC = 4x + 11
AC= 77
We can safely assume that,
AB + BC = AC
x + 16 + 4x + 11 = 77
5x + 27 = 77
5x = 77 - 27
5x = 50
x = </span>

x = 10
Hence,
AB = x + 16 = 10 + 16 = 26
Hence, proved.
Answer:
A. $,143,699,010
Step-by-step explanation:
Use a calculator my friend.
The pythagorean theorem states that a^2 = b^2 + c^2, where a is the side that opposes the right angle.
In this case, you have a and b, so you need c.
That means that c^2 = a^2 - b^2 so c is the square root of (a^2 - b^2) that means c = the square root of (676 - 576) which is 10in.
Answer:
38
Step-by-step explanation:
He will need 38 because,
17 muffins x 6 blueberries = 102 blueberries
he already has 64, so to find the remaining amount he needs
102 blueberries - 64 blueberries = 38 blueberries
