If jeanette had $936 in her checking account then the money in her savings account was 1/6 of this which is $156
Thats a total of 936 + 156 = $1092.
After moving the money to savings account the ratio savings : checking in 4:3 so she has 4/7 * 1092 = $624 in savings and 3/7 * 1092 = $468 in checking account.
Answer: 624 dollars in savings and 468 dollars in the checking account
Answer:
18/25 = 72%
Step-by-step explanation:
P(B ∪ F) = P(B) + P(F) - P(B ∩ F)
= 12/25 + 11/25 - 5/25
= 18/25
The probability a randomly chosen student plays either sport is 18/25 = 72%.
The intercept of 2 equations is a point that verifies both equations. By that I mean that if you replace the coordinates of this point in both equations, you would get the same y.
So, to do this, you use this form of expression: y=y
So you do the equality of both expressions, and find x.
But in your case, we have one equation that is not in the y= form: y+3=1/2x.
So you subtract 3 from each side, making it y=1/2x-3
Now, we can do y=y.
1/2x-3 = 5x-7x+8
1/2x-3=-2x+8
Then, we move the variables to a side, and the numbers to the other side of the expression, so you get:
1/2x + 2x = 8 + 3
5/2x = 11
To find x, you divide both sides by 5/2:
x= 11/(5/2)
x= 11*2/5 (when you divide 2 fractions, the result is equal to the first fraction multiplied by the inverse of the second)
x=22/5
So, the intercept of y+3=1/2x and y=5x-7x+8 is 22/5.
You can check your answer (this is very important):
y+3 = 1/2 * 22/5
y+3 = 22/10
y= -8/10
y=5x-7x+8
y=5(22/5)-7(22/5)+8
y=-8/10
Hope this Helps! :)
Nope the answer is -3t-1
Work:
-1/2(6t+2)
-1/2x2(3t+1)
-(3t+1)
-3t-1
