bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
8 - 5y = - 2x
2x - 5y = - 8
Answer:
Sophie
Step-by-step explanation:
For each runner, divide their time running by the laps they ran.
Piper: 8÷3≈2.7
Walker: 25÷10=2.5
Sophie: 3÷1=3
Sophie takes the longest time to run one lap, she is the slowest.
Answer:
312
Step-by-step explanation:
We can calculate by dividing it into 2 parts. The first part has length of 6, width of 4 and height of 2, so volume of this part is 48. Similarly, we can calculate that the volume of the second part is 264. Hence, the total volume is 312.
X+30+70=180
x+100=180. -100 both sides
x=80
|x=80° |
Answer: 120 divided by 4 = 30
