Answer:
$55
Step-by-step explanation:
Start with $245.
Calculate to total money the commuter needs to buys 20 weeks of tickets.
Multiply the number of weeks by the price per week.
20 X $15 = $300
He will need $300 for 20 weeks of tickets.
Subtract what he has from the amount he needs.
$300 - $245 = $55
Therefore the commuter will need to add $55 to the account to afford tickets for 20 weeks.
For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:
Where:
l: It's the side of the square.
We know that the area of a square is given by:
So, the area is:
Answer:
Answer:
We move all terms to the left:
4t+6-(-24)=0
We add all the numbers together, and all the variables
4t+30=0
We move all terms containing t to the left, all other terms to the right
4t=-30
t=-30/4
t=4.5
Brainiest?
Y = 1/3x - 10
sub in 1/3x - 10 in for y in the other equation
2x + y = 4
2x + 1/3x - 10 = 4...multiply everything by 3 to get rid of factions
6x + x - 30 = 12
7x = 12 + 30
7x = 42
x = 42/7
x = 6
2x + y = 4
2(6) + y = 4
12 + y = 4
y = 4 - 12
y = - 8
solution is : (6,-8)
