Answer:
0.5 mL
Step-by-step explanation:
If the device wasn't properly calibrated, in volume the number can be estimated with a 3 rule:
100%------4mL
12%-------x=12*4/100=0.48≈0.5mL rounding to the nearest tenth
8-2(3x+5)=0
8(-6x-10)=0
-48x-80=0
-48x=80
x= -8/5 or -1.6
Hey there! :)
Answer:
C. Both (2,1) and (4,9)
Step-by-step explanation:
To solve this question, simply plug in the coordinates of answer choices given into y = 4x - 7:
A.
1 = 4(2) - 7
1 = 8 - 7
1 = 1. A is correct.
B.
9 = 4(4) - 7
9 = 16 - 7
9 = 9. B is correct.
Therefore, the correct answer is C. Both (2,1) and (4,9) are solutions to this equation.
Hello from MrBillDoesMath!
Answer:
(1/3) x = (5/6)
Discussion:
I think you are asking for this equation:
(1/3) x = (5/6) => multiply both sides by 3
(1/3) 3 x = (5/6) 3 => as (1/3) *3 = 1
x = 5*3/6
x= 15/6
x = 5/2 = 2.5
Thank you,
MrB
