Answer:
P=$880,I=$92.40
P=$675,I=$94.50
P=$770,I=$96.79
Step-by-step explanation:
Simple interest rate is the interest eared on principal amount only over time:

#$880 at 5.25% for 2 years

Hence, the interest earned is $92.40
#$675 at 3.5% for 4 years:

Hence, the interest earned is $94.50
#$770 at 4.19 for 3 years:

Hence, the interest earned is $96.79
Answer:
You write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
Step-by-step explanation:
so for example, .005 would be 5x10^-2 and 500 would be 5x10^2
Answer:
18
Step-by-step explanation:
In step two. If we look on the left side of the equation in the first step, it reads 4(2x-4). When a number is multiplying an expression in brackets, we have to multiply every term in the brackets by the number in front of the brackets. In this case, it would be 4*2x + 4*(-4), which is 8x - 16. So the correct option would be the second (8x-16=16+2x) (the right side of the eqtn was 8+2x+8 and if we combine like terms we get 16+2x)
Y = -3x + 5
5x - 4y = -3
5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
5x + 12x - 20 = -3
17x - 20 = -3
+ 20 + 20
17x = 17
17 17
x = 1
y = -3x + 5
y = -3(1) + 5
y = -3 + 5
y = 2
(x, y) = (1, 2)
