Solve this like the less than was an equal sign to start
3p-16<20
3p-16=20
Add sixteen to each side
3p-16+16=20+16
3p=36
Divide each side by 3 to get p by itself:
3p=36
p=12
Replace the equal sign with the less than sign again
p<12

Factor 12q^2+34q-28. Include list of factors.
Misha Larkins [42]

Answer:

2(2q+7)(3q-2)=0

Step-by-step explanation:

lets set up the equation equal to 0:

12q^2+34q-28=0

now, lets factor:

2(6q^2+17q-14)=0

2(2q+7)(3q-2)=0

now, lets find the solutions:

2q+7=0

2q=-7

q=-3.5

3q-2=0

3q=2

q=2/3

8a + 12b = 92 6a – 4b = 4 -- a =? b = ?
Yanka [14]

Answer:

a = 4 b = 5

Step-by-step explanation:

8a + 12b = 92......eqn 1

6a - 4b = 4......eqn 2

multiply eqn 2 by 3

18a - 12b = 12.....eqn 2

add eqn 1 and 2 to eliminate b

26a = 104

a = 4

put a = 4 into eqn 2

18(4) - 12b = 12

72 - 12b = 12

72 - 12 = 12b

60 = 12b

5 = b
