Zach invested $1500. He earned 23.2% on his investment. Determine how much money he has now.
Alika [10]
To figure out 23.2%, first figure out how much 1% is by dividing 1500 divided by 100=15

Next, multiply the 15(1%) by the 23.2% to figure out how much that is.
23.2 x 15 = 348

Now, you have to add thr investment ($348) to his originsl amount of money ($1500).
$1500 + $348 = $1848

Zach now has $1848

Find an equation of variation in which y varies directly as x and y=420 when x= 100. Then find the value of y when x=11.
sweet [91]
Let's Simplify X to equal 1 by dividing by 100. then we divide 420 by 100 to get 4.2, so y=4.2 when x=1, we then multiply by each by 11.

y = 46.2
x = 11

Which expressions are equivalent to 5(-2k-3)+2k
bulgar [2K]

Answer:

-8k - 15

Step-by-step explanation:

5(-2k-3)+2k

At first, we will break the parenthesis. To break that, we will multiply the value inside the parenthesis by the adjacent number, that is 5. Again, we have to consider the Algebraic operation (Golden rule) -

[(-) x (-) = (+); (+) x (-) = (-)]

Therefore, since there is a minus sign in each of the value inside the parenthesis, the result will be minus as 5 is a positive integer.

or, -5*(2k) - (5*3) + 2k

or, -10k - 15 + 2k

or, -8k - 15 (after the deduction)

The answer is = -8k - 15
