GCF of 10 and 15 is 5
10/5 = 2
15/5 = 3
so it can donate to 5 schools, each receiving 2 computers and 3 printers
Your equation will be y=4x-1 and the intersection point will be (2,9). Hope this helps!
Answer:
<em>metres</em>
Step-by-step explanation:
You are finding the <em>height</em><em> </em>of the building with an angle of elevation, therefore we need to solve for <em>EC</em><em> </em>to add it to <em>BA</em><em> </em>[10 metres] and use TRIGONOMETRIC RATIOS to arrive at our conclusion. Just in case you have forgotten what they were, here they are:

We can now solve for <em>EC</em>:

<em>OR</em>

Now that you have solved for <em>EC</em>, you can now add it to your original 10 metres to get
<em>metres</em>. As a decimal, you would get
<em>metres</em>. You can go ahead and round this off if necessary.
** The reason why the <em>cotangent</em><em> </em>[or <em>tangent</em>] ratio was used was because <em>EA</em><em> </em>is equivalent to <em>DB</em> by the definition of a rectangle. It has two pairs of parallel and congruent sides with <em>four</em><em> </em><em>right</em><em> </em><em>angles</em>. Plus, that is the <em>adjacent</em><em> </em><em>side</em><em> </em>of the triangle, while <em>EC</em><em> </em>is the <em>opposite</em><em> </em><em>side</em><em> </em>of the triangle, so we knew our ratios were correct.

Answer:
6
Step-by-step explanation:
Before solve this you've to know that,
( + ) × ( - ) = ( - )
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
Let us solve now.
13 + (-7)
13 - 7
= 6
