Answer:
x=2
Step-by-step explanation:
2x+x+5= 4x+3
first combine like terms, so add 2x and x which is 3x
3x+5= 4x+3
Then subtract 3x from both sides 3x-3x+5= 4x-3x+3
5= x+3
subtract 3 on both sides 5-3= x+3-3
2=x
Answer Check:
substitute x for 2
2(2)+2+5=4(2)+3
multiply 2 times 2 and add 2 which is 6 and 4 times 2 which is 8
4+5= 8+3
add the number to together to see if the two equations are equal
11 = 11
the answer is right
Answer:
160 is greater than 2 and a half minutes.
Step-by-step explanation:
The amount A that Patrik will cash is given by the compound interest formula:
A = C (1 + i)ⁿ
where:
C = initial amount of money
i = interest, written as a decimal number
n = number of periods
In our case, the interest is compoundend quarterly, but we have a time in years. Therefore, we need to transform years in quarters:
n = 15×4 = 60
Now, we can apply the formula:
A = 400·(1 + 0.035)⁶⁰
= 3151.24$
Hence, the correct answer is B) 3151.24$
