Answer:
Step-by-step explanation:
Since you have an expression for y, it is convenient to use it.
-2x + 8(3x) = -22 . . . . . substitute 3x for y in the second equation
22x = -22 . . . . . simplify
x = -1 . . . . . . . . . .divide by 22
Substituting this value into the expression for y:
y = 3(-1) = -3
The solution is (x, y) = (-1, -3).
Answer:
$4945
Step-by-step explanation:
the interest on the loan can be found by using this formula:
I = P · r · t P = principal, r = interest rate, t= time (in years)
I = 4600(.05)(1.5)
I = 345
Total Amount = Principal plus Interest
Total Amount = 4600 + 345 = $4945
<em>175</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>25 = 5²</em>
<em>35 = 5×7</em>
<em>Lcm = multiply together each of the prime numbers with the highest power</em>
<em>Lcm(25 ; 35) = 5²×7 = 25×7 = 175</em>
<em>Good luck !</em>
