Solution:
we are given that
A student has some $1 and $5 bills in his wallet.
Let there x $1 bills and y number of $5 bills.
He has a total of 14 bills that are worth $34.
So we can write
Now solve these two equations together using substitution as follows
Hence there are 9 $1 bills and 5 bills are of $5.
Answer:
294cm²
Step-by-step explanation:
You didn’t convert from meters to centimeters.
It was 2.94m².
That equals 294cm².
Equation for this line is y = -2x + (-4)
<u>Step-by-step explanation:</u>
Step 1:
Slope intercept equation for a line is of the form y= mx + b, where m is the slope and b is the y-intercept.
Step 2:
Calculate slope of the given line.
⇒ m = (y2 - y1)/(x2 - x1) = (2 - (-2))/(-3 - (-1)
⇒ m = 4/-2 = -2
Step 3:
Find y-intercept
⇒ b = - 4
Step 4:
Substitute values to get equation
⇒ y = -x -4 or y = - (x + 4)
Answer:
x=5
Step-by-step explanation:
x+7=12
x=12-7
x=5
In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:
5/4 = y - 1/4
5/4 + 1/4 = y - 1/4 + 1/4
6/4 = y
y = 6/4
Don't forget to simplify y:
y = 3/2
