Answer:9x-9=7 or 9x-9=-7
Step-by-step explanation:
An absolute value is the distance from zero, therefore the answer can not be negative. In this case, 9x-9=7 and 9x-9=-7 both work, because 7 and -7 are the same distance from zero.
Answer:
$1600
Step-by-step explanation:
4%/100 ×10,000
= $400
30,000-10,000
=20,000
=20,000×6/100
=$1200
=1200+400
=$1600
If you would like to know for how many days will 1/2 of a bag of dog food last, you can calculate this using the following steps:
1 day ... 3 bags of dog food
x days = ? ... 1/2 of a bag of dog food
1 * 1/2 = 3 * x
1/2 = 3 * x /3
x = 1/2 * 1/3
x = 1/6 of a day
The correct result would be 1/6 of a day.
I think its 3,600, because you usually have to multiply the numbers.
Answer:
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
Case Q: i = p(0.01)(2) = 0.02p
Case R: i = p(0.015)(2) = 0.03p
In case R, the interest earned is 0.03p, which is 1.5 times the interest earned in case Q.
