Answer:
y = 7 - 2x/3
Step-by-step explanation:
Make the y alone, so 3y = -2x+21
Divide everything else by 3, so y = -2x/3 +7
You end with the answer of y= 7-2x+3
Step-by-step explanation:
8|x+2|-6=5|x+2|+3
|8x+16|-6=|5x+10|+3
I've been thinking... Is that | or (? Are you sure it's |?
Oh well, I'm continuing...
8x+16-6=5x+10+3
8x+10=5x+13
3x=3
x=1
24th is the answer, you just double the 12 because it’s both a number 3 and 4 go into
Answer:
x=3 and y=4
Step-by-step explanation:
You can use c^2 = a^2 + b^2 to solve for the length of the other leg. Just substitute the values to the variable then transpose to get the value of the missing variable.
Given: a = 13; c = 21
Required: b - other leg
Solution:
c^2 = a^2 + b^2
21^2 = 13^2 + b^2
441 = 169 + b^2
b^2 = 272

b = 16.49 cm</span>
