Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is Jean's car....it gets 30 miles per gallon
I think its not a correct solution of given equations.
Answer:
32 seconds
Step-by-step explanation:
first 8 secknds gives us the value of set 2.5l
2.5L to make 10 =
10÷2.5=4
That said 2.5L fills 1pL by 4 giving us;
4×2.5= 10L
Answer:
subs with credentials get paid $87 per day. subs without credentials get paid $55 per day.
Step-by-step explanation:
let x be the cost subs with credential get paid per day and y be the cost subs without credential get paid per day
so we get
using simultaneous equation by substitution method you get x=87 and y=55
Answer:
Step-by-step explanation:
A kite is a quadrilateral, so the sum of its angle measures is 360°.
7x + 65 + 85 + 105 = 360
7x = 105 . . . . . . . . . . . . . . . . . subtract 255. This answers the second part of the question: the missing angle is 105°, so is congruent to the 105° angle given.
105/7 = x = 15 . . . . . . . . . . . . divide by the coefficient of x
