Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25
To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.
X - X + 25
Which gives u a difference of 25
Step-by-step explanation:
Given data
Let the cheese be x
And strawberry be y
So
6x+6y=96-------1
x+4y=52----------2
Solving 1 and 2 simultaneously
Let us multiply equation 2 by 6 we have
6x+6y=96
6x+24y=312
-0-18y=-216
18y=216
y=216/18
y=12
Put y=12 in equation 2
x+4*2=52----------2
x+8=52
x=52-8
x=44
cheese =44
strawberry =12
Answer:
6/2(1+2)= 1
Step-by-step explanation:
First: you do what is in the parenthesis:
1 + 2 = 3
6 / 2(3)
now multiply
6 /6
now divide.
1.
so the answer 6/2(1+2)= 1

Answer:
(2,-3)
Step-by-step explanation:
I used substitution and rearranged the second equation to y=-2x+1. Then I replaced the y in the first equation with -2x+1. So, I got 3x-5(-2x+1)=21. When you solve that you get 13x=26 or x=2. Then you replace x with 2 in either equation and end up with y=-3.
Option B. The balance will increase more and more each year, but it will not be linear. Unlike simple interest that tends to produce linear graphs; the returns when compounded can get very astronomical. The mathematics behind compound interest is "multiplication". Your funds get multiplied, not added or decreased and this is because the previous interest is accrued on the principal and the current interest. Unlike compound interest simple interest is linear, it increases (or decreases) steadily. As time goes on with simple interest, one's returns increases very steadily but this is unlike compound interest. So yes, Option B, the balance will increase more and more each year, but it will not be linear.
