Answer:
48
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse (longest side) is the sum of the squares of the other two sides. Let x represent the unknown side.
73² = x² +55²
5329 = x² +3025 . . . evaluate the squares
2304 = x² . . . . . . . . . subtract 3025 from both sides
48 = x . . . . . . . . . . . . take the square root of both sides
The exact length of the third side is 48.
To find out what t + 1 is, we first must find out the value of t.
We know that t + 8 = -12, so all we need to do to solve for t is subtract 8 from both sides.
t + 8 = -12
t + 8 - 8 = -12 - 8
t = -20
So now that we know the value of t, all we need to do to find t + 1 is insert the value of t into the variable and solve.
t + 1 = ?
-20 + 1 = ?
-19
And there we have it.
t + 1 = -19

Answer:
C = 0.175x + 5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>A phone company has a monthly cellular data plan where a customer pays a flat monthly fee $5 and then a certain amount of money per megabyte (MB) of data used on the phone</em>
Given:
- Customer uses 80 MB
- The monthly cost will be $19.00 (flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone)
So let:
- C is the cost of the data plan
- x is amount of money per megabyte (MB)
We can form the standard equation:
C = mx + b <=> C = mx + 5
In this situation, we have:
19 = m*80 + 5
<=> m = 0.175
So the a linear equation is: C = 0.175x + 5
Hope it will find you well
Answer:
your answer would be 1
Step-by-step explanation:
The whole equation is divided by 3 to get 2x-4y=5, but since there is a 6 we need to subtract 1 away to get 5.
