I think the answer is $7.90.
$18.96 divided by 12 is $1.58.
5 roses at $1.58 each is $7.90.
So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get
10x = 1.777777...
And then subtract x from 10x and then you get 1.6.
So that means that
10x - x = 9x
and 1.7777... - 0.17777... = 1.6
So now to solve for x, divide both sides by 9
To get 1.6/9 = x
Or 16/90 = x
Or 8/45 = x
(That explanation made no sense)
Answer:
Step-by-step explanation:
-3(10 + (-5) / (10 - (-5))^2 =
-3(10 - 5) / (10 + 5)^2
-3(5) / (15^2)
-15 / 225 reduces to -1/15
Answer:
The amount invested at 9% is $93000
The amount invested at 10% is $303000
Step-by-step explanation:
Let the amount invested at 9% interest rate be x
And the amount invested at 10% rate be y
Simple Interest from x in a year = 0.09x
Simple Interest from y in a year = 0.1y
But y = 24000 + 3x
And the sun of the interests, 0.09x + 0.1y = 38670
Now we have a simultaneous eqn
y = 24000 + 3x (eqn 1)
0.09x + 0.1y = 38670 (eqn)
Substitute y into eqn 2
0.09x + 0.1(24000 + 3x) = 38670
0.09x + 2400 + 0.3x = 38670
0.39x = 38670 - 2400
x = 36270/0.39 = $93000
y = 24000 + 3x = 24000 + 3 × 93000 = $303000
Answer:
a < 4
Step-by-step explanation:
7 + a < 11
Subtract 7 from each side
7+a-7 <11-7
a < 4
