Topic: **Business english homework****Question:**
so i ace everything academically except math;
''A*'' in English Language
''A'' in ICT
''A'' in History
''B'' in Business studies
''Pass'' in PHSE
''B'' in Art
but i'm on a grade ''D'' overall and i know that it's my natural weakness and i'm paranoid i'm not going to get into college because i'll fail math in my last exam i got a grade ''C'' which puts me on a ''D'' overall and i need to get it upto a ''C'' but i want a ''B'' preferably to reassure my self i'll definitley get the requirements for college (''C'') so how do i get a grade ''B'' in mathematics? Thanks 10 points best :)

Take GOOD notes Study with a good student Do all homework Get a good tutor if you need to ASK QUESTION IN CLASS as soon as you dont understand something May need to put work, gameboy, and TV aside

I'll only explain it at number one then I'll solve the other problems for you. Just substitute an equation in the other. 1.) y = 5x + 3 y = 4x + 4 You could write this as: 4x + 4 = 5x + 3 4-3 = 5x - 4x x = 1 Substitute this in either equation. y = 5(1) + 3 y = 8 2.) y=-4+18 y= -3x+13 If it has really no x, then this is how the solution will go: y = -4 + 18 y = 14 14 = -3x + 13 1 = -3x x = -1/3 3. y=5x+20 y=-2x-8 -2x - 8 = 5x + 20 -8 - 20 = 5x + 2 -28 = 7x x = -4 y = -2(-4) - 8 y = 0 4. y=-5x-21 y=-2x-6 -2x - 6 = -5x - 21 -2x + 5x = -21 + 6 3x = -15 x = -5 y = -2(-5) - 6 y = 10 - 6 y = 4 5. y=3x-8 y=-4x+6 -4x + 6 = 3x - 8 6 +8 = 3x + 4x 14 = 7x x = 2 y = -4(2) + 6 y = -8 + 6 y = -2 6. y=-4x+18 y=3x-3 3x-3 = -4x + 18 7x = 21 x = 3 y = 3(3) - 3 y = 6 7. -3x-7y=4 y=-3x+20 Just isolate y or x (whichever you prefer) first before substituting. -3x - 7y = 4 -7y = 4 + 3x y = -(4/7) - (3/7)x y= -3x + 20 -3/7x - 4/7 = -3x + 20 Multiply the whole equation by 7 to avoid working with fractions -3x - 4 = -21x + 140 -3x + 21x = 140 + 4 18x = 144 x = 8 y = -3(8) + 20 y = -24 + 20 y = -4 8. -9+3y=-7 y=3x-7 Again, isolate y (or x). I don't know if there is a typo or not... 3y = -7 + 9 3y = 2 y = 2/3 2/3 = 3x - 7 (2 + 21)/3 = 3x 2 + 21 = 9x 22 = 9x x = 22/9 9. y= 4x+6 -8x-4y=24 I was stupid in the earlier questions. If you already have at least one equation that has an isolated variable (x or y), then you can substitute it to the other equation. Anyway, the answer is the same. -8x - 4(4x+6) = 24 -8x - 16x -24 = 24 -24x = 48 x = -2 y = 4(-2) + 6 y = -8 + 6 y = -2 10. -2x+6y=10 -4x+y=9 Just isolate the variable from an equation that is easily manipulable. y = 9 + 4x -2x + 6(9+4x) = 10 -2x + 54 + 24x = 10 22x = -44 x = -2 y = 9 + 4(-2) y = 1 11. -7x+6y=-12 x-7y=14 You could also try isolating x here: x = 14 + 7y -7(14 + 7y) + 6y = -12 -49y + 6y - 98 = -12 -43y = -12 + 98 -43y = 86 y = -2 x = 14 + 7(-2) x = 0 12. 8x+2y=-10 -2x+y= 7 y = 7 + 2x 8x + 2(7+2x) = -10 8x + 14 + 4x = -10 12x = -24 x = -2 y = 7 + 2(-2) y = 3

u just substitute by either making y=something or x=something then plug that into the equation 1. y=5x+3 y=4x+4 4x=y-4 x=(y-4)/4 now plug x=(y-4)/4 into y=5x+3 u get y=5(y-4)/4 + 3 y=(5y-20)/4+3 y=(5/4)y - 5 + 3 y=(5/4)y -2 -1/4y=-2 y=8 simple

You didn't specify the math break down, the ranges for the letter grades and what your number grade is. If you could do that, maybe we could help you. But best thing to do is to start studying. That's the only thing that can help you, anyway. It's the only option.

I can't tell you specifics if you don't give us a breakdown of your scores. Get a tutor or go in for extra help or something.

1. -13x < -156 x >12:divide -13 on both sides.since you are dividing by a negative number you have to reverse the sign I tested this multiple times and I am positive this is the right answer. ANSWER: x > 12 2. -168 > -12a 14>a or a<14 ANSWER: a < 14
