1 + 1 = 2

If we have one apple and get another apple, then we now have 2 apples.

We can also do the reverse to confirm our answer:

1 = 2 - 1

1 = 1

Which is true.

It is also not a matter of easy or not, this may be easy for us but hard for a baby.

I hope this helps! :)

What are the length and width of a rectangle if the length exceeds the width by 55 inches and the perimeter is 270 inches?

astra-53 [7]

Here, P = 2L + 2W, and L=W+55. Subbing W+55 for L in P = 2L + 2W, we get:

P = 2(W+55) + 2W = 270 in
2W + 110 + 2W = 270 in, or 4W = 160 in. Then W=40 in, and L=(40+55)in.

Answer:

$35\ ways$

Step-by-step explanation:

we know that

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

$C(n,r)=\frac{n!}{r!(n-r)!}$

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

$n=7\\r=3$

substitute

$C(7,3)=\frac{7!}{3!(7-3)!}\\\\C(7,3)=\frac{7!}{3!(4)!}$

simplify

$C(7,3)=\frac{(7)(6)(5)4!}{3!(4)!}$

$C(7,3)=\frac{(7)(6)(5)}{3!}$

$C(7,3)=\frac{(7)(6)(5)}{(3)(2)(1)}$

$C(7,3)=35\ ways$

10 (> or = to) 2.00 + 0.75x

Sorry. I don't have that symbol on my keyboard. but her ten dollars has to be greater than or equal to whatever the cost is so that's why that symbol has to be used in this case. 2.00 is the flat rate and add 0.75 multiplied by however many miles she is taking!

Hope this helps!
