16/12=X/X-3
Cross multiply
16x-48=12x
Subtract
4x=48
Divide
X=12
Answer:h=-2
Step-by-step explanation:
Equation:h(-6) = |2(-6) +1| +1
Step 1: Simplify
=-6h=12
Step 2:Divide both sides of the equation by -6
-6h/-6=12/-6
h=-2
Answer:
its a rectangle
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
Divide each side by 1.6 to get m alone, thus getting the answer, so 1.6m/1.6 and 40/1.6
Answer:
The sum of the interior angles of any triangle are equal to 180
therefore in this triangle, m<a+m<c+m<b=180
we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,
9x-26+a=180
9x+a=206
a=206-9x
(206-9x)+(2x-12)+(4x+43)=180
combine like terms
-3x+237=180
-3x=-57
x=19
if x=19 then we can substitue it in for c
4x+43=c
4(19)+43=c
c=119
