Answer:
- New York style: $14
- Chocolate Marble: $16
Step-by-step explanation:
We can let n and c represent the costs of the New York style and the chocolate marble cheesecakes, respectively. Then the two sales are ...
11n +7c = 266 . . . . . . . Rob's sale
4n +14c = 280 . . . . . . Amy's sale
The ratio of coefficients of c is a "nice" number (2), so we can eliminate the c variable easily to solve this. Dividing the second equation by 2 and subtracting it from the first gives ...
(11n +7c) -(1/2)(4n +14c) = (266) -(1/2)(280)
9n = 126 . . . . . . simplify
n = 14 . . . . . . . . divide by 9
Filling this into the first equation, we have ...
11(14) +7c = 266
7c = 112 . . . . . . . . subtract 154
c = 16 . . . . . . . divide by 7
One New York style cheesecake costs $14; one chocolate marble cheesecake costs $16.

Answer:
The correct statement would be: The positive number is 1/2 unit less than the opposite of the negative number.
Step-by-step explanation:
All stamemts are true except for the last one:
<em>The positive number is 1/2 unit more than the negative number.</em>
We can see in the plot that 1.5 is above zero and -2 is below zero.
So, -2<1.5
The opposite number of -2 is 2 and we can see that opposite number is 1/2 greater than 1.5. So, -2<1.5<2

Answer:
-5
Step-by-step explanation:
Pick 2 points on the line:
(-2, 5) and (-1, 0)
Radiation from the sun heats the Earth's surface by means of rays that are trapped in the atmosphere and allow the Earth to have constant heat.
<h3>How is the Earth's surface heated?</h3>
The surface of the Earth heats up due to the sun's rays that hit it and when they enter the atmosphere they are reflected on the surface being trapped between the atmosphere and the surface.
Another important aspect to keep in mind is that the rays strike at different angles throughout the Earth, for example:
- In the equatorial zone they affect directly, so this zone tends to be more quality than others in which the rotation and translation of the Earth cause the rays to enter in less or more quantity throughout the year.
