Answer: $13
Step-by-step explanation:
To determine the solution arithmetically in two steps, first divide 68.25 by 3 and then subtract 9.75 from the result. To determine the solution algebraically, set up and solve the equation 3(x+9.75)=68.25. Each friend paid $13 for dinner.
Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2
Step-by-step explanation:
This is what I get
You have to place the decimal numbers over the power of 10.since its 6 places to the right will be 10^6(1000000).
464646/1000000
Now cancel common factors by factoring out 2.
232323/500000=0.464646
Answer:
284.24
Step-by-step explanation:
by multiplying 0.68 to 418 we get 68% of 418
