Answer:
-5(a + 3) = 55
Step-by-step explanation:
-5a -15 = 55
-5a = 70
70/-5 = a
70/-5 = -14
The answer is -14
(x+3)/((x+4)+3)=5/6
(x+3)/(x+7)=5/6
6(x+3)=5(x+7)
6x+18=5x+35
x=35-18
x=17
17/(17+4)=17/21
check : (17+3)/(17+4+3)=20/24=5/6
Answer: 70%
Step-by-step explanation:
A basket contains:
5 yellow balls
3 blue balls
2 white balls
What would be the probability of randomly picking a ball and the ball not being blue?
So, we can find the probability of picking up a blue ball. Let's do that first.
To calculate the probability of getting a blue ball, we need to divide the number of blue balls by the number of possible balls.
The number of blue balls = 3
The total number of balls = 2 + 3 + 5 = 10 balls
3 blue balls divided by 10 balls = 0.3.
If you multiply 0.3 by 100%, it will give you a probability of finding a blue ball equal to 30%
Now, we just need to find the probability of NOT finding a blue ball. Because we have 30% of finding a blue ball, we just need to subtract 30% from 100%.
100 - 30$ = 70%
The probability of not getting a blue ball is equal to 70%.

12-3=9
30+7=37
I believe you just plug in any two numbers that will come out to 9 when subtracted or 37 when added.
