the answer is 3
Step-by-step explanation:
3 pizzas equal $9.00 so in order to know how much each pizza was, we will have to do division:
9 divided by 3
9/3
3
Answer:
<u>LENGTH OF AC IS 6</u>
Step-by-step explanation:
Given :
<em>the side AC = x ;</em>
we need to find x;
<em>since ∠A = ∠C , It's an isosceles triangle . i.e ,</em>
<em>the sides opposite to the angles ( AB and CB ) are also equal.</em>
thus ,
side
AB = x+4 ;
CB = 3x-8 ;
thus AB = CB or ,
x+4 = 3x-8 ,
2x = 12 ,
x = 6 ;
<u>therefore the side AC is 6.</u>
By formula of surface area of cube
Answer:
All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:
given the second expression:
x - y = 1
We'll replace y with it's value in the first expression:
x - (y) = 1
x - (5 - 2x) = 1
Now we can expand the resulting equation:
x - 5 + 2x = 1
So <em>neither</em> of the answers provided are correct.
You can then solve for x:
x - 5 + 2x = 1
x - 5 + 5 + 2x = 1 + 5
x + 2x = 6
3x = 6
3x/3 = 6/3
x = 2
After that, you can find y by plugging x into either of the two original equations:
y = 5 - 2x
y = 5 - 2(2)
y = 5 - 4
y = 1
