Answer:
Mean: 34.875, Median = 34.5, Mode = 34, Range = 6
Answer:
4 hours, $60
Step-by-step explanation:
Assuming "d" is equal to the dollars Jacob earned and h= hours, you start by setting the equations equal to each other, since both are equal to "d."
15h=10h+20
Subtract 10h from both sides (to combine like terms) so the equation becomes:
5h=20
Divide 5 from both sides, to isolate "d" :
h=4
The number of hours Jacob worked is 4, as the equation above shows. To find the amount of money Jacob made, substitute 4 as "h" into the two original equations:
d= 15(4) d=$60
d=10(4)+20 d=$60
Jacob earned $60 dollars in 4 hours.
Step-by-step explanation:
m arc AD = (2×108) - 142 = 216-142= 74°
m<A = 180-108= 72°
Y=7.5
Isolate the variable by dividing each sides by factors that don't contain the variable. Hope this helps!
