The answer for this question is x=32
Answer:
Step-by-step explanation:
Let's call lifeguarding L and car washing W. In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.
If she works 10 hours, that is the number of hours worked between both jobs. Therefore, the equation for the NUMBER of hours worked is
L + W = 10.
If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W. The MONEY she earned together by doing both those jobs is
13L + 12W = 124
There you go!
Answer: 1:2 ratio
Step-by-step explanation:
Total-red roses=pink roses
24-16=8
8:16
GCF: 8
16/8=2
8/8=1
1:2 ratio
pink:red
Try this options:
a. total - 6 digits, '6' - 1 digit, then probability of rolling a '6' is 1/6;
b. total - 6 digits, '6' - 1 digit, then probability of rolling 1,2,3,4,5 is 5/6;
c. if probability of rolling a '6' is p and not rolling a '6' is q, then p+q=1;
d. if expected probability of one rolling a '6' is 1/6, then numbers of times of rolling a '6' during 120 times is 120/6=20 times.
