_ _ _ here are the three digits
Total:
5 ways to choose the first (1, 3, 5, 7, 9)
9 for the second
8 for the third
5*8*9=360.
5 ways to choose the first digit (1, 3, 5, 7, 9)
5 ways to choose the second ( 2, 4, 6, 8, 0)
8 for the third
5*5*8=200
200/360=20/36=10/18=5/9, but it's not one of the choices.
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
24 * 5 = 120
120 + 6 = 126 - total cost - meals and service
6/126 *100% = 4,76%
service charge was 4,76% of total costs.
Answer:
Choice 3. -4x-3<13
Step-by-step explanation:
First, you will use process of elimination and cross out any obvious wrong answers. You can see that the symbol would not be flipped yet so the "<" would be pointing to less than. That eliminates choice 1 and 4. Now, You can observe the 3rd step and see that -4x<16, to get that, you would need a "-4x" in the equation. Number 2 is 2x so that can't be right. Therefore, the answer is choice 3. This simple process of elimination and looking for clues will help you greatly in multiple choice problems instead of solving it the hard way.
