Answer:
x=3, y=23
x=6, y=41
x=8, y=53
x=9, y=59
Step-by-step explanation:
x=3, y=6(3)+5
y=18+5
y= 23
x=6, y=6(6)+5
y=36+5
y= 41
x=8, y=6(8)+5
y=48+5
y=53
x=9, y=6(9)+5
y=54+5
y=59
It may be can be number 1 (a)
Set up a ratio:
You drove 72 minutes and 100 km = 72/100
You want the number of minutes (x) to drive 150 km = x/150
Set the ratios to equal each other and solve for x:
72/100 = x/150
Cross multiply:
(72 * 150) = 100 * x)
Simplify:
10,800/100x
Divide both sides by 100:
x = 10800/100 = 108
This means it would take 108 minutes to drive 150 km.
Now subtract the time you have already driven to fin how much more you need:
180 - 72 = 36 more minutes.
Use inverse operations. 11 minus 3 is 8. 8 divided by 2 is 4. 4 minus 1 is 3.
(NOT SURE) x COULD equal 3, but the lines, as far as I know. relate to absolute value. So it could be |-3 + 1| and that would equal 4.
and if you put a variable next to a number, you multiply. so you multiply 2 by 3 plus 1, or 2 times 4, which equals 8. 8 plus 3 equals 11.
there :)
