Hi there!
A year is 365 days, correct?
If we save our pennies up from January 1st to December 31st, you'd have 3 dollars (since 100 pennies is 1 dollar) and 65 pennies left over. If it was a leap year, however, you'd have 3 dollars and 66 cents. :)
Hope this helps! :D
Answer:
k = -13/3
Step-by-step explanation:
Step 1: Flip the equation.
k + 7/3 = -2
Step 2: Subtract 7/3 from both sides.
k+ 7/3-7/3 = -2 - 7/3
k= -13/3

10x^2 - (2 - 3x) + (5x - 3x^2)
=7x^ + 2x - 2
Answer:
<em>Mechanic A worked for 5 hours</em> and <em>Mechanic B worked for 15 hours</em>
I hope my answer and explanation helped!
<u>okay to get started you need to make a system of equations:</u>
x= number of hours worked by mechanic A
y= number of hours worked by mechanic B
x + y= 20
95x + 60y= 1375
<u>substitute in an equation:</u>
x + y= 20
y= 20- x
95x + 60(20-x)=1375
<u>Solve for x</u>
95x + 1200 - 60x=1375
35x =175
x= 5
<u>plug in x to solve for y</u>
x + y= 20
5 + y= 20
y=15
<u>Check work</u>
then you're done :D
Answer:
-4y -12
Step-by-step explanation:
We cannot solve, but we can simplify
3(y-4)-7y
Distribute the 3
3y -12 -7y
Combine like terms
3y-7y -12
-4y -12
