Answer
x=3 or (3,0) and if you need it y=-2x+3
Step-by-step explanation:
I'm not very good at explaining things, sorry
Y = 6.3x + 67.4
The average height of a 5 year old boy is
6.3(5) + 67.4 = 31.5 + 67.4 = 98.9 cm
Answer:a
Step-by-step explanation:
Answer:
16. 70%
17. 100%
Step-by-step explanation:
16. As seen here, there are 10 marbles in total. Out of those marbles, there are 7 green marbles.
We can set up a "part to whole" fraction such as 7/10
Then we just find the % value by finding an equivalent "x to 100" ratio (percentages go up to 100)
7/10 = x/100
1000 = 7x
70 = x
17. Fortunately, there doesn't seem to need too much math involved as the only possible marbles are red and green. Therefore, you have a 100% chance of getting a green or red marble.
Hope that helps a bit!
