3(30+2). first you would do 3x30. 3x30=90. then you would do 3x2. 3x2=6. then you would add. 90+6=96. hope this helped
You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28
Then divide both side by 2 so you get x=14 which is your answer :)
ANSWER: x=14
How many 8 can we fit in 144?
Start with 8•10=80, can’t fit another 80 so
Continue with 8•5=40 we have now 80+40=120 and we need 144 so are left 24
Finish with 8•3=24
Now we can group them
Multiplication: 8•10+8•5+8•3=144
Distributive : 8•(10+5+3)=144
So 144/8=10+5+3=18
m<H + m< D = 180°
Since m<H and m<D are supplementary angles.
128°+m<D =180°
m<D = 180-128
m<D = 52°
Answer: m<D = 52°
