I’ll mark you if you’re right:)

z=74 , x=6

Step-by-step explanation:

Z = 74

12x+34=180-74

12x=72

x= 6

x=6

z=74

Step-by-step explanation:

z and 74 are vertical angles and vertical angles are equal

z = 74

74 and 12x+34 are supplementary angles since they form a line. Supplementary angles  add to 180.  

74+ 12x+34 = 180

Combine like terms

12x+108 = 180

Subtract 108 from each side

12x = 180-108

12x = 72

Divide by 12

12x/12 = 72/12

x =6

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

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.
