Answer:
Step-by-step explanation:
d = (4×180) - (3×90)
d = (720) - (270)
d = 720 - 270
d = 450

Follw me = 10 thanks
Mark as brainliest = 10 thanks
1 thanks to me = 2 thanks
that would be 3/4
11
is very easy and nohard
the answer is 12
Simplify both sides of the equation.
12(b−10)+2b=25
(12)(b)+(12)(−10)+2b=25(Distribute)
12b+−5+2b=25
(12b+2b)+(−5)=25 (Combine Like Terms)
52b+−5=25
52b−5=25
add 5 to both sides.
52b−5+5=25+5
52b=30
multiply both sides by 2/5.
(25)*(52b)=(25)*(30)
b=12
