5x+30- 2x+9
3x+39 is the expression.
Looking at the given question, we can find several important information's and based on thm we can easily calculate the amount after 10 years.
Principal amount = $550
Rate of interest per year = 3%
Number of years the amount is to be kept = 10 years
Now we get put these information's in the formula of finding amount of money kepy in simple interest.
Amount = P(1 + rt)
Where
p = principal amount
r = rate of interest
t = Time
Then
Amount = 550[1 + (3/100) * 10)]
= 550 [1 + 3/10]
= 550 * (13/10)
= 55 * 13
= 715 dollars
So the total amount in my account will be $715
Answer choice D. is a repeating decimal
Answer:
The method used is substitution method
x = 2, y = -6
Step-by-step explanation:
Given the simultaneous equation
Y = −3x ..... 1
4x + y = 2 ... 2
Substitute equation 1 into 2
4x + (-3x) = 2
4x - 3x = 2
x = 2
Get y:
y = -3x
y = -3(2)
y = -6
<em>Hence the value of (x, y) is (2, -6)</em>
