2b+b-4

You can't simplify that any more.

1/a = 1/b: cross multiplying gives a = b

7

Unless B is 9 or greater, 7/8 is closer to 1. I converted everything to decimals to help me decide.

63 / 7 = 9. Therefore b = 9

68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11

16

a=7 b=9 ab=? ab is the multiplication of a & b there fore the value of ab=7*9=63

8/9

The number is 34 a + b = 7 a = 7 − b 10a + b + 9 = 10b + a 10(7 − b) + b + 9 = 10b + 7 − b 70 − 10b + b + 9 = 9b + 7 72 = 18b 4 = b 3 = a

Your numbers are -2 and -7 and here's how you find them: a + b = -9 b = -9 - a b = (-9 - a) [We have now found the value of b in terms of a.] a - b = 5 a - (-9 -a) = 5 a +9 + a = 5 2a + 9 = 5 2a = -4 a = -2 [We have solved for a, and now we substitute that back in to solve for b.] a + b = -9 -2 + b = -9 b = -7 [And now we've solved for b, the second unknown, and solved our problem.]

This question is somewhat confusing. Do you mean it as (a) 25 over 35, or (b) 35 over 25? Here are the answers for both. (a) 25/35 = 5/7 or 0.714 (rounded) (b) 35/25 = 7/5 or 1+(2/5) or 1.4

i cant tell you why a is afraid of b.. but i can tell you why 7 is afraid of 9... BECAUSE 7, 8 (ate), 9!!!!!

-1

The answer depends on the value of B.

(a+b)2

-9

B evaluates to 8. Here is how the formula may look: 15 = 7 + b Now we have to isolate the b. The easiest way is to subtract the 7. Remember that what we do to one side, we must do to the other side. 15 - 7 = 7 + b - 7 It is time to simplify. On the left we know that 15 minus 7 is 8. On the right, the +7 and the -7 cancel each other out and can all be removed. That leaves b. 8 = b

i think 9 or 10

b+9=2 sbtract nine both sides b=2-9 b=-7
