Answer:
1.
90+27
2.
90 = 9 x 10
3.
27 = 9 x 3
4.
So apply the distributive property would be:
90 + 27 = 9(10 + 3)
That would be it i'm sure glad to help
What are the statements? Cannot answer without them.
Answer: 24cm
Step-by-step explanation:
Inradius = r
c = the hypothenuse
a & b = the other 2 sides of the triangle
Inradius formula: r = 1/2 * (a+b-c)
Plug in what we know.
2 = 1/2 * (a+b-10)
Multiply both sides by 2.
2*2 = 1/2 * (a+b-10) * 2
4 = a+b-10
Add 10 to both sides.
4+10 = a+b-10+10
14 = a+b
Perimeter formula: P=a+b+c
Plug in what we know
(remember a+b=14).
P=14 + 10
P = 24
<u>Answer:
</u>
6.3 trees.
<u>Step-by-step explanation:
</u>
We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.
Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.
Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.
