Well, to see how much one apple costs, we'll have to divide 7 by 4.55. You will get 65 cents. Each apple is .65 cents. 

Now you multiply .65 by 9. You will get 5.85

9 apples cost $5.85.

You divide $4.55 by 7.
$0.65 times 9 = $5.85

What is the value of a?
Anna007 [38]

Answer:

15 units

Step-by-step explanation:

By using the Pythagoras Theorem,

C^2 = A^2 + B^2

Substitute in the given values,

25^2 = a^2 + 20^2

625 = a^2 + 400

625 - 400 = a^2 + 400 - 400

a^2 = 225

a =  \sqrt{225}

= 15

Hope this too helped! ^^

I'd recommend watching a video or two on the topic of Pythagoras Theorem, if this explanation isn't clear enough.

-3 ≤ 6x - 6 < 39 (seperate into two inequalities)

6x - 9 ≥ -3

6x - 9 < 39 (solve the inequalities)

x ≥ 1

x < 8 (find the intersection)

x ∈ { 1 , 8 }

I need to know the solution to this
Alex73 [517]
There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate

Look at equation 1, -2x+y=10 this can quite easily be manipulated to show y=10+2x.

Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one 4x-y=-14 \Rightarrow 4x-(10+2x)=-14 which can then be solved for x since there is only one variable 4x-10-2x=-14 \Rightarrow 2x=-4 \Rightarrow x=-2 and then with our x solution we can work out our y solution by using the equation we manipulated y=10+2x = 10+(2 \times -2) = 10-4=6.

So the solution to these equations is x=-2 when y=6
