Answer:
<h2>(4x + 3) + (-2x + 4) = 2x + 7</h2>
Step-by-step explanation:
(4x + 3) + (-2x + 4)
= 4x + 3 - 2x + 4 <em>combine like terms</em>
= (4x - 2x) + (3 + 4)
= 2x + 7
Answer: x= 2.5, y = 10
Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:

And cross-multiply:

Then solved for x and y:

A picture types of the models would be helpful.. but they could be found in a rectangular shape or square such as width=2 and length =12 vise versa or w=4 and length = 6 , etc etc
Old price: 1,137.50 / 350 = 3.25
New price (at least): 1,500 / 350 = 4.3 (result is rounded)
Answer: factors of 10 are 1, 2, 5, and 10.
Step-by-step explanation: You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.
