Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
Answer:
15
Step-by-step explanation:
the pattern is like this
start with 1 then add 2 equals 3
start with 3 then add 3 equals 6
so 6 add 4 equals to 10
and the 5th term will be 10 add 5
equals to 15
Since 25% is 1/4, you multiply 60 by 1/4 to get how many students took Spanish class last year. So, 60 times 1/4 is 60/4, which is 15. Then you subtract 15 from 60 to get 45. So, 45 students took Spanish class last year.
hi!
its not a function since it has a =5
this is an equation
Distance = rate * time, or rewritten rate = distance / time ---> r = d/t
<span>4 laps, 1 mile per lap = 4 miles = d </span>
<span>12 minutes = 1/5 of hour (12 min/60 min = 1/5) = t </span>
<span>r = 4/(1/5) mph </span>
