Answer:
Step-by-step explanation:
x =135(being opposite angles of a parallelogram)
5/6(x-1)=4
(x-1)=(4*6)/5
x-1=24/5
x=24/5 + 1
least common multiple=5
x=(24+1*5)/5
x=29/5
Answer: x=29/5
To check:
5/6(x-1)=5/6(29/5 -1)=5/6[(29-5)/5]=5/6(24/5)=(5*24)/(6*5)=120/30=4
Answer:
-2x^2-6x-15
Step-by-step explanation:
Answer:
The answer is 1.
Step-by-step explanation:
Plug in the values to make the equation -3+4*2/2
According to the order of operations, you should multiply what you can first.
so 4*2 = 8
Then 8 divided by 2 = 8/2=4
Then -3+4=1
2x-9= (-7^2)
2x-9=49
2×=49+9
2x=58
x=58/2
x=29
