Make sure and use distributive property on the ones multiplying by what’s in the parentheses
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
Answer:
The volume of the right rectangular prism is 420 3/4 ft cubed.
Step-by-step explanation:
The formula to find volume is:
Volume = L x W x H
5 1/2 x 8 1/2 x 9 = 420 3/4 ft cubed
131+-5 is equal to 126
To make it less confusing it’s just 131-5
Answer:
y=mx+b
Step-by-step explanation:
You would definitely want to memorize this important formula because you'll see this slope intercept form often in your Algebra I class, where m=slope and b=y-intercept.
