Answer:
ty can buy 7 journals
Step-by-step explanation:
The total bill was inclusive of the one-time payment of $50 and an additional payment of $25 per month. The only unknown variable here is the amount of months you've had the phone. This can be solved by isolating the unknown variable, like so:
Let: x = number of months
Total bill = one-time payment + monthly payment * number of months
$375 = $50 + $25x
375 - 50 = 25x
325 = 25x
325/25 = 25x/25
x = 13
Therefore, you've had the phone for 13 months.
Answer:
1/10
Step-by-step explanation:
P(1st marble yellow) = Number of yellow / total
= 2/5
We keep the marble. Now there are four marbles in a bag. Three are green, and one is yellow.
P(2nd marble yellow) = Number of yellow / total
=1/4
P (1st yellow, keep, 2nd yellow) = 2/5 * 1/4
= 2/20 = 1/10
We know that the triangle is made up of 180°
To find "x" we need to know the two angles of the triangle.
We also know that the supplementary angles are made of 180°
In this case the supplementary angle would the angle were 100° and the missing value is.
Since supplementary angles are made of 180°
180°-100° = 80°
Now we know the two angles of the triangle.
Since the triangle is made up of 180°
180° = x + 70° + 80°
x + 150° = 180°
x = 180° - 150°
x = 30°
