You have $121 in a savings account and save $1 2
per week. Your friend has S9 I in a savings
account and saves SI 7 per week. How many
weeks will it take for you and your friend to have
the same balance?
Answers
It will take 6 weeks for you and your friend to have the same balance.
First, you must set up your equation, with [tex]x[/tex] representing the amount of weeks
until you and your friend have the same balance.
[tex]121+12x=91+17x[/tex]
Then, you must subtract 91 on both sides.
[tex]30+12x=17x[/tex]
Next, subtract 12x on both sides.
[tex]30=5x[/tex]
Finally, divide 5 on each side

Angle Z is 21 degrees larger than twice the measure of angle T. If ∠Z and ∠T are supplementary, what is the measure of angle T? *
Answers
angle T = x
angle Z = 2x + 21
We know that supplementary angles add up to 180 degrees.
180 = x + 2x + 21
Combine like terms.
180 = 3x + 21
Subtract 21 from both sides.
159 = 3x
Divide both sides by 3
53 = x
angle T = 53 degrees

Im not 100% sure but here is what i have...
based on the given inequality the new one would be 15n>105+4.50n,
First subtract the 4.50n from the right side of the inequlaity sign.
Now you should have 10.5n>105
second, plug in a random number to see if she will make money or not..
I used 10, so plug 10 in for "N".
it will look like this, 10.5(10)>105
now do the math and get, 105>105,
which brings me to the cunclution she breaks even..

Thank you so much :)
Answers
Answer:
The answer is 12Step-by-step explanation:
The slope of a line given two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,3) and (0,−9)
The slope is
