6+4/a+b/3 when a=4 and b=3

8

Step-by-step explanation:

Plug in a =4 and b=3 into  6+4/a +b/3

6 + 4/4 + 3/3

= 6 + 1 + 1

= 8

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
