15/7 or 2 1/7 (same number but the first one is an improper fraction and the other is a mixed fraction)
Answer:
12x^2-7x-10
Step-by-step explanation:
I did binomial into binomial method
3x(4x-5)+2(4x-5)
12x^2-15x+8x-10
12x^2+(-15+8)x-10
12x^2-7x-10
Answer:
$6.44
Step-by-step explanation:
Take your $32.20 and X's it by 20% = $6.44
Mark brainilist pls!
Sure, here is how I broke it down. The bird is flying a constant X miles per hour with a wind speed of Y miles per hour. So, there are two equations that you use to solve. Here they are:
X+Y=12
X-Y=4
Now, you have to use substitution or elimination to solve (I will use elimination). To use elimination, you simply add both equations together to get:
2X=16
Solve for X by dividing by 2.
X=8. We already established that X is the speed of the bird. Plug X back into either of the equations to find the windspeed.
(8)+Y=12
Subtract 8 from both sides.
Y=4. We already established that Y is the windspeed.
So, the speed of the bird (X) is 8mph and the speed of the wind (Y) is 4mph.
Hope this helped!!
Answer:
See below
Step-by-step explanation:
For SIMPLE interest :
1210 + 1210 * .09 * 7 = <u> $ 1972.30</u>
For ANNUAL COMPOUNDING of interest
1210 ( 1 + .09)^7 = <u>$ 2211.93</u>
