Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05
Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x
Answer:
30 pages
Step-by-step explanation:
Because if he reads 10 pages in 1/3 of a hour 1/3 of an hour is 20 mins so x2 means 30 pages
Answer:
308
Step-by-step explanation:
let the number be x
then,
94.248=30.6% of x
94.248=30.6/100 *x
94.248= 0.306x
94.248/0.306=x
308=x
so the number is 308.
Solving problems means making choices. Typically, effective problem-solving skills result in “happier, more confident, and more independent” individuals. When children tackle problems on their own, or in a group, they become resilient
Answer:
Step-by-step explanation:
1.)
3x=3
x=1
2+y=0
y=-2
solution: (1,-2)
2.)
6y = -36
y = -6
-4x+12 = -12
-4x=-24
x = 6
solution: (6,-6)
