There are 45 oranges and 90 apples in the beginning.
Step-by-step explanation:
Let the no. of orange be 'b'
Let the no. of apples be 'a'
Given that,
2b = a
3(b-15) = a
3b - 45 = a
3b - 45 = 2b
3b - 2b = 45
b = 45
2b = a
2(45) = a
a = 90
There are 45 oranges and 90 apples in the beginning.
Answer: m = -2
Step-by-step explanation:
8(3m+5)=2m-4
24m + 40 = 2m - 4
24m - 2m = -40 - 4
22m = -44
m = - 44/ 22
m = -2
Answer:
Step-by-step explanation:
(x,y) = (48/7, -22)
Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
Taylor will earn $21 more in compounded interest than in simple interest.
Given:
Principal = 2100
interest rate = 1.85%
term = 8 years
Simple Interest = Principal * interest rate * term
= 2100 * 1.85% * 8
= 310.80
Compounded Interest = Principal * (1+r)^t
= 2100 * 1.0185⁸
= 2100 * 1.158
= 2431.80
Interest from Compounded Interest : 2431.80 - 2100 = 331.80
Simple Interest = 310.80
Compounded Interest = 331.80
331.80 - 310.80 = 21
