Answer:
D.) Elliott has 212 cans, Amelia has 45 cans
Step-by-step explanation:
257 = x + (5x - 12)
257 = 6x - 13
+13 +13
270 = 6x
/6 /6
45 = x (the amount of Amelia's cans)
257 - 45 = 212 (the amount of Elliott's cans)
please rate and thank : )
T is a linear function of C ==> T = mC + b
Each additional chirp C corresponds to an increase in T of 0.25 ==> m = 0.25
T = 52 when C = 20 ==> 52 = 0.25(20) + b ==> b = 52 - 5 = 47
So T = 0.25C + 47
When C = 100 then T = 0.25(100) + 47 = 25 + 47 = 72
When C = 120 then T = 0.25(120) + 47 = 30 + 47 = 77 so the
temperature range is between 72 and 77 when there are between 100 and
120 chirps per minute
Answer:
first y then x because y represents 22 and x represents 4 a week.
Let number of driveways , she shoveled on Sunday = x
And for 4 driveways , Kendra charges = 4*11=44
Therefore,
143 = 44 + 11x
And that's the model for the given situation .
Subtracting 44 from both sides,
143-44 = 11x
99 = 11x
Dividing both sides by 11
x = 9
Therefore she shoveled 9 driveways on Sunday .
Answer:
The total number of train tickets Aaron can buy=4
Step-by-step explanation:
a). Determine first expression
Let the number of each mode of transport be as follows;
bus ticket=b
train ticket=t
b). Determine the second expression
Let the total cost be expressed as shown;
total cost=(cost per bus ticket×number of bus tickets)+(cost per train ticket×number of train tickets)
where;
total cost=$520
cost per bus ticket=$64
number of bus tickets=b=3
cost per train ticket=$82
number of train tickets=t
replacing;
(64×3)+(82×t)=520
192+82 t=520
82 t=520-192
82 t=328
t=328/82=4
t=4
The total number of train tickets Aaron can buy=4
