The number of checks for credit union to have a better deal is an illustration of inequalities.
<em>The credit union is a better deal when writing 2 or more checks per month.</em>
Let the number of checks be x.
<u>For the local bank (L):</u>
The equation is:
<u>For the credit union (C)</u>
The equation is:
For credit union to have a better deal, then:
So, we have:
Collect like terms
Hence, the number of checks per month must be greater than 1 for the credit union to have a better deal.

Answer:5
Step-by-step explanation:
Ab + c = d
In other words, you can put it like this:
1(ab) + 1c = 1d
Since our answer choices, let's try to get a by itself.
ab + c = d
Subtract both sides by c.
ab = d - c
Now, a is being multiplied by b, so we need to perform the opposite order of operations (divide).
Divide both sides by b.
You're left with:
a = (d - c)/b
Your answer is D.)

'of' means multiply
half a dozen means 12/2=6
6 of one thing means 6 times x
plus means ad
half a dozen of another mean 6 times y
they are added
6x+6y
2 variables
it says 'of the other' so they are diferent

if the legs are x then the hyptonuse is x√2
18=hyptonuse=x√2
18=x√2
divide both sides by √2
18/√2
make denomenator nice
times by √2/√2
(18√2)/(2)
9√2
one leg is 9√2 cm
