C and D tell me if those are wrong because i'm only a beginner and i would like to learn from my mistakes
C. Since 3÷8=3/8. You could also multiply 3/8×8 which is simply adding 3 eight times.
Step-by-step explanation:
.454 kilograms= 1 pound.
Multiply .454 by 160
4.54
160
--------
000
2724 0<--Place marker
45400<--Double Place Marker
- - - - - - - -
72640 <-- Add
To find decimal point, count decimal place (Number of digits after the decimal on both numbers you multiply together) In this case, it's 2 ( 5 and 4 in 4.54) So, you count two spaces from right to left in your answer and tah dah!
72.640 (Zero isn't needed- just a placemarker)
Hope I was helpful :)
Slope intercept form: y= mx +b
Parallel lines= same slope
Find slope of this line first:
2x + 3y =8
Subtract 2x from left side and add it to right side.
3y = -2x + 8
Divide by 3
Y= -2x/3 +8/3
slope= -2x/3
Y= mx + b —-} b is y intercept which is unknown and m is slope
Plug in -2/3x for slope.
Y= -2/3x +b
To find y intercept plug in point (-2, 3)
Y= -2/3x+b
3= -2/3(-2) +b
3 = 4/3+b
3-4/3 =b
5/3 =b
Y= -2/3x +5/3 is new equation
