Please help me out! its urgent:(

for the third problem a = cb

for the 4th problem x = 5a + g

for the 2nd problem p = (q - 3r) / 4

for the first problem x = (-9 - z) / y

for the last problem: b = 15

A = 1/2 bh

75 = 1/2 b(10)

75 = 1/2 10b

multiply both sides by 2

150 = 10b

divide by 10 from both sides

15 = b

b = 15

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
