Ok here are my interpretations for these sentences.
1.)2r+3s=13
2.)t/40=12-(1/2*s)
3.)200-3x=9
4.)1/3x+25=2x
5.)m^2-n^3=16
6.)2z=2(v+z)
Hope this helps!=)
Not sure I understand this but
5x+2=0
5x = -2
x = -2/5
Or
x = -.4
Answer:
Consider the number of children to be x.
So, 144 coins were divided amongst x children.
For x-3 children, each child would have 16 coins
So, (x-3)*16=144
Solving for x, x-3=144/16
or x-3=9
or x=9+3=12
Answer is 12
Answer:
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
4c + 6a ≤ 120:
You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.
4c + 4a ≤ 100:
You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.
4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120
4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Mean is when u add up all the numbers and divide it by the number of numbers.
74+46+57+56+62 = 295
295/5 = 59
Median is the middle number. (Order from least to greatest)
46,56,57,62,74
The middle number is 57.
Mode is the number that shows up the most. In this case there is no mode.
Range is the highest number minus the lowest number.
74-46 = 28
