Answer:
126 apples
Step-by-step explanation:
Let the number of apples picked by Mary=m
Cindy picks 6 times as many as Mary= 6Xm=6m
John picks 8 times as many as Mary= 8Xm=8m
Altogether they picked a total of 135 apples.
m+6m+8m=135
15m=135
m=135/15
m=9
We want to determine how many apples John and Cindy Picked.
John Picked 6m apples
Cindy Picked 8m apples
Their combined total= 6m+8m =14m
Since m=9
14m =14 X9 =126 apples
John and Cindy picked a total of 126 apples
Answer:
256 Coins
Step-by-step explanation:
On the first day, Jada starts with one coin, so all you have to do here is multiply it by 2.
Day 1: 2 coins
Day 2: 2 x 2 = 4 coins
Day 3: 4 x 2 = 8 coins
Day 4: 8 x 2 = 16 coins
Day 5: 16 x 2 = 32 coins
Day 6: 32 x 2 = 64 coins
Day 7: 64 x 2 = 128 coins
Day 8: 128 x 2 = 256 coins

Answer:
Step-by-step explanation:
xy = 300
x + y = 50 Solve for y
y = 50 - x substitute into xy = 300
x(50 - x) = 300 Remove the brackets.
50x - x^2 = 300 Bring the left to the right.
0 = x^2 - 50x + 300
This is a quadratic. It will have 2 solutions.
a=1
b = - 50
c = 300
Put these into the quadratic equation.
It turns out that x has two values -- both plus
x1 = 42.03
x2 = 6.97
x1 + y1 = 50
42.03 + y = 50
y = 50 - 42.03
y = 7,97
(42.03 , 7.97)
====================
x2 + y2 = 50
6.97 + y2 = 50
y2 = 50 - 6.97
y2 = 43.03
(6.97 , 43.03)
Well, if ABC=QRS
Then AB=QR
So if AB=50 then QR=50
