yes
Substitute x and y into the
equation we have
0+4 .(-5)=-20
<=>-20=-20
satisfy the condition
Sure! I'll try!
2x + 29 +11 = x + 28
First, you would put like terms ( the x ) on the same side.
2x + 29 + 11 = x + 28
-2x -2x
Giving you: 29 + 11 = -3x + 28
Then, you would add 29 and 11 together to get 40.
Next, you'd put the 28 on the other side.
40 = -3x + 28
-28 - 28
Giving you: 12 = -3x
Answer:
x=9
Step-by-step explanation:
.5x+.7 = .3x+2.5
-.7 -.3x
.2x=1.8
/.2 /.2
x=9
.5(9)+.7=5.2
.3(9)+2.5=5.2
<span>The probability of having either a boy or a girl is statistically 0.5, and this makes sense at the chromosomal level - there are genetic reasons for it.
Why the observed ratio in families is different than predicted ratio is simply due to chance. Just like getting a string of heads when you flip a coin, you got 'lucky' - not real luck but just random coincidence. Your next coin toss could be a tail.

Answer:
The answer is C, or $104.50.
Step-by-step explanation:
You'd think you'd get off easy by just adding the admission prices together. But also recognize that's an outlier compared to the other answers, and it's not just one adult and one child. It's two adults and four children. So, you need to multiply the admission price by the number of people, then add together. $15.25 times 4 children is $61.00. $21.75 times 2 adults is $43.50. Add those.
