Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. 
(the short side lengths) = 
(the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
By looking at the graph, we can visually determine that the value of y when point x = -2 is <u>-4.</u>
Answer: b=13, t=29
Step-by-step explanation:
Substituting the first equation into the second,
12 egg=2.09
then your adding 6 more eggs to get 18 eggs and 6 is half of 12
so you would be adding half the price
2.09/2=1.05
so then add 2.09+1.05=3.14
So 18 eggs would be $3.14
Hope this helps!! :D
Answer:
-5x - 6y + 8
Step-by-step explanation:
-2(x - 4) -3(x + 2y)
-2x + 8 - 3x - 6y
-5x - 6y + 8
Hope this helps!
