First subtract 3 from both sides of the equal sign.
9s + 3 = 57
- 3 -3
9s = 54
Then divide both sides by 9.
9s = 54
/9 /9
s = 6
You can check it by plugging it back into the equation.
9s + 3 = 57
9 * 6 + 3= 57
54 + 3 = 37
57 = 57
Yep! It's correct! :)
Hope that helped. Algebra can be tricky sometimes I know but it's really just balancing equations.
sides 2 * 6 * 4 =48 and 6*4=24
bottom 6*2.5 =15
2.5*4=10
10*2=20 that's the area of 2 smaller sides
Step-by-step explanation:
we add up the dimensions together 48+20+15=83
so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83
Area = Length X Width
Perimeter = l(2) x W(2)
what are the measures of this rectangle?
Factor dem groups
find greatest common factor
24=2*2*2*3
40=2*2*2*5
common is 2*2*2=8
answer is 8 groups
The restriction of the expression as given in the task content is; x +y = 0.
<h3>What is the restriction of the expression?</h3>
The expression in the task content is rational;
(1-x-y)/(x+y).
On this note, the restriction to the expression is the values which render the denominator of the expression equal to 0 and consequently the expression value to undefined.
Hence, the restriction is; x+y = 0.
