Step-by-step explanation:2(2) + 1(1) =
4 + 1 = 5 which is true
hope this helps
Answer:
Step-by-step explanation:
3+4=8-x
x=8-7
x=1
T us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3
The formula to find the simple interest I for a deposit P with a simple interest annual rate of r during t years is:
In this problem, we have:
P = $4000
t = 4
r = 5% = 5/100
So, using those values in the formula, we obtain:
