Answer:
B. 8x - 3
C. 8x + 12
Step-by-step explanation:
64 is a perfect square, meaning it has two factors that are identical (8), and 36 is also a perfect square, but in this case, you don't see two 6's in the answer choices.
12 and -3 give you a product of -36, so your answer choices would be:
(8x - 3) (8x + 12)
If you're unsure, you can multiply them together to check if they come out to the unfactorized expression.
Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1
y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3
solution is : (-1,3)
Answer:
<em>3/8 of the box cereal</em>
Step-by-step explanation: First you must convert 3/4, 1/8, and 1/4 so they have to same denominator. Four can go into eight two times, so you must multiply the numerator by two. So your new fractions are 6/8, 1/8, and 2/8. Now you must subtract 1/8 and 2/8 from 6/8. When you subtract 1/8 from 6/8 you get 5/8. Now subtract 2/8 from 5/8 and you get <em>3/8. </em>That is how you get the answer, I hope this helps you.
Its 16.
So you have 12 miles on that trail, and markers every 2/3 of the way there. If you were to divide 2 with 3 then you can get the decimal of the fraction. Which in this case it’s 0.75. So every single 0.75 of the mile there is a marker. Divide 12 with 0.75 and you get 16 markers.
Hoped this helped in some way.
