Answer:
8xy-3y + 2(9x-5y+4) = 18
Step-by-step explanation:
We need to find the value of the given expression:
8xy-3y + 2(9x-5y+4) ....(1)
when x = 3 and y = -4
Put the values of a and y in equation (1)
8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)
= -96 +12 + 2(27 + 20 +4)
= -84 + 2(51)
= -84 + 102
= 18
Hence, the value of the given expression is 18.
Answer:
-38.85 or -24
Step-by-step explanation:
What I do is start with the brackets along with the rest of the numbers involved
2(10) is basically 2 x 10= 20
-39 + 3/20
3/20 = 0.15
-39 + 0.15 = -38.85
Unless if 3/2(10) has 3/2 as a fraction, the answer would be -24
