Answer:0.4166
Step-by-step explanation:
4x -2(12x-1)= 14
4x-24x+2=14
-20x+2=14
-20x=12
x=-0.6 or -3/5
2.1
If the number was 2.15, you would round to 2.2 because any place that is 5 or greater rounds up and any place less than 5 rounds down.
.1 is the tenths place
.11 is the one hundredths places
3. 5x+2y=-19
10x-7y=-16
10x+4y=-38
10x-7y=-16
11y=-22
Y=-2
10x+4c-2=-38
X=-3
4. 10x-4y=20
2x+7y=43
10x-4y=20
10x+35y=215
-39y=-195
Y=5
10x-4x5=20
X=4
