First of all I would find 1% by dividing 1546 by 100:1546/100 = 15.46Then I would multiply this by 24 to find 24%:15.46x24 = 371.04 So 24% of 1546 is 371.04

X 2.87 or -0.87y-0.87 or 2.87

Begin by expanding brackets using FOIL (first, outer, inner, last) method (demonstrated on whiteboard to make clear). Multiplying the first term of each bracket gives 3x², multiplying outer ter...

2x+3y=7 ----(1)x-y=1 -----(2)First, look at how you can eliminate one of the unknowns. Here we can multiply the second equation by 3 to make eliminate the "3y" in the first equation. We will the...

Here we use the ratios given to calculate the answer. First we sum add 7 and 4 to find total parts. 7 + 4 = 11. Then we divide 88 by 11. 88/11 = 8.This means we know that each part in the given ratio is 8...
