Step-by-step explanation:
(e)
- 
= 1
Multiply through by 12 to clear the fractions
4(2x - 1) - 3(3x - 1) = 12 ← distribute parenthesis and simplify
8x - 4 - 9x + 3 = 12
- x - 1 = 12 ( add 1 to both sides )
- x = 13 ( multiply both sides by - 1 )
x = - 13
---------------------------------------------------------------
(f)
- 5 = 24 ( add 5 to both sides )
= 29 ( multiply both sides by 4 )
3m = 116 ( divide both sides by 3 )
m = 
--------------------------------------------------------------
(g)
- 
= 3
Multiply through by 6 to clear the fractions
15(y + 2) - 8(y + 1) = 18 ← distribute parenthesis and simplify
15y + 30 - 8y - 8 = 18
7y + 22 = 18 ( subtract 22 from both sides )
7y = - 4 ( divide both sides by 7 )
y = - 
Answer:
~109.3
Step-by-step explanation:
23 x 9.5 x 1/2 =
218.5 x 1/2 = 109.25
That rounds to 109.3 square yards
Hope that helps!
Answer:
Any negative number and 0 works for the expression.
Step-by-step explanation:
Looking at this type of equation, we know that either EVERY negative number and 0 or EVERY positive number and 0 will work for this equation, since nothing is being added and we're just working with absolutes/negatives.
Let's try a random positive number in the expression
So this positive number doesn't work, let's just test with another one.
So we know that positive numbers won't work with this expression.
Let's test 0 quickly, just to make sure.
So 0 works.
Let's try a few negative numbers now.
So yes, this does work. Let's try one more negative number.
This works. So, every negative number and 0 work with this equation.
Hope this helped!
To round the answer u need to see if the ending number on the right is above or below 5 if it’s 5 or above then you make the number behind it go up(8–>9) and if it’s below 5(4 and lower) then that stays the same
