"is" means "=" 48% = .48 "of" means "multiply let the number = "N" so we have
7800 = .48N divide both sides by .48
7800 / .48 = N = 16,250
We have
7000(1 + .062/4)^(4 * 8) = about $11451.32
So, let the integers be n, n+1 and n+2......and we have
3(n+2) = n + n + 1
3n + 6 = 2n + 1 subtract 2n, 6 from both sides
n = -5
n+ 1 = -4
n + 2 = -3
Check
3(-3) = -5 + -4
-9 = -9
To find the percent.......divide 25 by 60........you will get a decimal answer.......move the decimal two places to the right and add a "%" sign....that's it...
log5+3logx+logy .......using log.... a + log b = log(ab)
log5+logx3+logy =
log (5x3y)
"Of" means multiply .... 65% = .65
So
.65 * 7200 = 4680
2x-x^3+5=0 the easiest way to solve this is by graphing
Here's the graph.........https://www.desmos.com/calculator/o6jsoeeqjm
It has one real solution at about(2.095, 0)
l x + 4 l > 0 take the expression out of the absolute value
x + 4 > 0 subtract 4 from both sides
x > -4
We also have
x + 4 < 0 subtract 4 from both sides
x < -4
So the solution is (-∞, -4) U (-4, ∞ )

Don't worry, Anonymous......parentheses and brackets seem optional, too!!!
