# for example, 0.47x 0.18=tHow do I explain to my 5th grader how to get the answer and show the work with the new math? (answer)

When you multiply ANY two numbers the resulting number has decimal places that is the sum of each numbers' decimal places. Here you have 0.47 with TWO decimal places and 0.18 with TWO decimal places the answer 846 (I did not consider the decimals yet) should have a total of FOUR decimal places...

# The perimeter of a rectangular picture is 66 in. The length is 3 in. greater than the width. Find the width and length. (answer)

Perimeter of a rectanlgle = 2(L+W) = 66 (given) But the Length is 3 ft more than width →  L = W + 3 Therefore 2(W+3+W) = 66 2(2W+3) = 66 Divide by 2 on boths sides 2W+3=33 subtract 3 from both sides 2W+3-3=33-3 2W=30 divide by...

(Yx2)+8=Y+12 2Y + 8 = Y + 12 Subtract  Y from boths sides 2Y -Y + 8 = Y  - Y + 12 Y + 8 = 12 Subtract 8 form both sides Y + 8 -8 = 12 - 8 Y = 4

Wrong Question. Where did  point F come from?  You said ABC and EBD are pair of verticle angles. And then question went on givin some new angle EBF , but we do not know where point F is? The way you gave the above question is not correct.

# d+ 2d - 8 = 0 (answer)

First place the equation i the standard format of ax2+bx+c. Your equation d2 + 2d - 8 = 0 is already in this format. Cool, now you need to find the product of the end terms (ac) = (1)(-8) = -8 Find the factos of -8 so that their sum adds up to the center term (b)= 2 (-4) X 2...

# Leah is 6 years older than Sue. John is 5 years older than Leah. Total combined age is 41. How old is Sue? (answer)

Leah is 6 years older than Sue. John is 5 years older than Leah. Total combined age is 41. How old is Sue? Leah's age = 6 years + Sue's age. John's age = 5 years + Leah's age. Combined age of Leah + Sue + John = 41 years Now let us their ages as; Leah's age = L years,...

# how do I factor a trinomial that has a value greater than 1 in the x squared term? (answer)

4x2 + 12x + 9 Find all possible factors for 36 such that their product is 36 and sum ends up 12 Let us first distill it down to the lowest factors 36 = 4.9 = 2.2.3.3 = 2.3 X  2.3 = 6 X 6 (6+6 = 12!) so 6 X 6 are the factors we want (other possible factors are 12X3,...

# I need help solving the equation: 6x= 7 - 4y (answer)

You have two unknown variables (x and y) The question probably asked to solve for both or x or y. In any case you need TWO equations, since there are two unknowns. The question is therefore incomplete without a second equation What is the complete question?
