Answer:
3) x=4 4)x = 9 5) x=5
Step-by-step explanation:
3) first you have to find the inside of the angle. A straight line = 180*
180-(19x+3) = 177-19x
Than you add all the angles up to equal 180.
(177 - 19x) + (11x-2) + (9x+1) = 180
if you simplify this x = 4. You can check your answer by subbing in for x.
4)first you have to find the inside of the angle. A straight line = 180*
180- (17x-23) = 203-17x
Than add the sides up to equal 180. keep in mind there are 2 of the same angles.
(203-17x)+(7x+2)(2) = 180
Simplify
x=9
5) 180-151=29* this is the inner angle.
(11x-1)+(20x-3)+29=180
31x+25=180
x=5
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5
Check answers. (Plug them in to make sure they work.)
b=5 (Works in the original equation)
Answer:
b=5
Hope this helps! ;)
5 3/8 and 43/8. hope that helped
So, there are 12 pieces. since he ate 1/4 of it already, he divided the rest to 1/12 each equivlent to a whole pizza. since 1/6 of it was left, so, he got 1/4 for himself, each friend had one, then 1/6 was left. before, he made it equivlent to a twelve piece minus 4. 12 - 4 = 8, 1/6 means 6 pieces or 3 for 12. final answer, it would most likely be 6 or 4. thank you.
