10(4x+3)-9x
40x+30-9x
31x+30
I think the answer is A
Answer: Four times the amount of flour for the raisin bread plus 2.5 cups equals 12.5 cups total. The equation is 4x + 2.5 = 12.5. First, I subtract 2.5 from both sides, and then I divide both sides by 4. Each loaf contains 2.5 cups of flour.

Answer:
240 more girls
Step-by-step explanation:
210 + 160 = 370
100 + 30 = 130
370 - 130 = 240
For this case we have that the initial and final peach diameters are:
According to the difference percentage we have:
That is to say, the peach grew by almost 93%. That is, almost twice its diameter.
Answer:
the peach grew by almost 93%. That is, almost twice its diameter.
Hello from MrBillDoesMath!
Answer:
(3,6) is not a point of intersection of the lines.
Discussion:
Let's check if the supposed point of intersection, (3,6), is on both lines. Start by substituting x = 3 and y = 6 in the equation y = 4x -2. This gives
y = 4x - 2
6 = 4(3) - 2 = 12 -2 = 10
6 does not equal ten so the supposed point of intersection doesn't even lie on one of the lines! Hence (3,6) is not a point of intersection of the lines.
Thank you,
MrB
