Answer:
This expression is not equivalent to -9.
Step-by-step explanation:
Given the expression
Use distributive property to eliminate the brackets:
Use commutative property to rearrange the terms:
Hence, this expression is not equivalent to -9.
Answer:
y= 40° , z = 90°
Step-by-step explanation:
Angle z is a right angle and is therefore 90°
Angles in a triangle add up to 180°
So we can work out y by making an equation:
Therefore y =40°
Answer: m = 9 .

Explanation:
_________________________________________
Given: (3 ¾) m = (33 <span>¾) ; Solve for "m" ;
</span>_________________________________________
Method 1):
Rewrite the fractions in "decimal form"; and rewrite the equation:
_____________________________________________
(3.75) m = 33.75 ;
Divide each side of the equation by: "(3.75)" ;
to isolate "m" on one side of the equation; and to solve for "m" ;
____________________________________________________
(3.75) m / 3.75 = 33.75 / 3.75 ;
____________________________________________________
m = 33.75 / 3.75 ;
m = 9 .
____________________________________________________
Method 2):
___________________________________________________
Rewrite the fractions as improper fractions:
____________________________________
3 ¾ = [ (4*3) + 3 ] / 4 = (12 + 3) / 4 = 15/4 ;
33 ¾ = [ (4*33) + 3 ] / 4 = (132 + 3) / 4 = 135/4 ;
_______________________________________________
And rewrite the equation:
_______________________________________________
(15/4)m = (135/4) ;
_______________________________________________
→ Multiply the entire equation (both sides) by "4" to eliminate the fractions ;
_______________________________________________
→ 4 * (15/4)m = 4 * (135/4) ;
→ All the "4's" on BOTH sides "cancel out" to "1" ;
and we are left with:
_______________________________________________
→ 15 m = 135 ;
_______________________________________________
Now, divide EACH side of the equation by "15" ; to isolate "m" on one side of the equation; and to solve for "m" ;
_______________________________________________
→ 15 m / 15 = 135 / 15 ;
_______________________________________________
→ to get: m = 9 .
_______________________________________________
Method 3):
______________________________________________
Similar to "(Method 2)" directly above, except the step at which we get to:
________________________________________
→ (15/4)m = (135/4) ;
________________________________________
Instead of multiplying each side of the equation by "4" ;
We divide EACH side of the equation by "(15/4)" ; to isolate "m" on one side of the equation; and to solve for "m" ;
__________________________________________
→ (15/4)m / (15/4) = (135/4) / (15/4)
= (135/4) ÷ (15/4) = (135/4) * (4/15)
= (135*4) / (15*4) = (540) / (60) = 54/6 = 9 .

Answer: The product of 12*3/4 is less than 12
Step-by-step explanation: I can see this right from the start by noticing that to be at least 12, then 12 would have to be multiplied by at minimum 1 meaning 12*1=12 anything less than 1 would result in a lesser value than 12
Answer:
yes
Step-by-step explanation:
if theyre both negative it will stay negative
