Answer:
Number line C
Step-by-step explanation:
First, you isolate x. This gives you x>=3+4 or x>= 7. Next, you find a number line greater than or equal to which cancels out A and D. Now whichever line starts on 7, is the answer which is C
Answer:
B
Step-by-step explanation:
Charla uses 2 cups of mix per 6 cups of water.
2/6 = 1/3
Rae uses 3 cups of mix per 7 cups of water.
3/7
To compare these fractions, we need to find the common denominator. In this case, it's 21.
1/3 = 7/21
3/7 = 9/21
9/21 is greater than 7/21, so Rae's lemonade will taste stronger.
Answer:
I'm not 100% correct but this is what I believe proportionality is where k=y/x and k is proportionality constant
$6.57: 3 pounds of orange
y dollar: x pounds of orange
so the proportion
$6.57 y
_____ = _____
3 x
6.57×
_____ = y
3
2.19x = y
so k = 2.19
Answer: 7.5×10^-4
Step-by-step explanation:
0.00075
Scientific notation means standard form
There are 3 zeros in front of the 7
So take the decimal to the back of 7
You have
7.5
Since you are counting backward, it will be negative
So we have
7.5×10^-4
