Answer:
Final answer in simplified form is
Step-by-step explanation:
Given expression is
Now we need to find an equivalent expression for
First we can distribute the positive sign and remove the parenthesis the combine like terms
Hence final answer in simplified form is
Answer:
Wouldn't it be 6 x 4 because there are 4 groups but 6 tens in each of these groups, right? so it would basically be 6 x 4= 24 all in total
Step-by-step explanation:
( also this is a 3rd grade standard I believe or 2nd grade :< )
It's quite simple if you think about it
Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
<u>x + y = 195</u>
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120
True, they are on the same line so B has to be the midpoint since AB is not the biggest segment.
If the discriminant, b^2 — 4ac is positive (or > 0), then the solution will be two (2) distinct real solutions.
If the discriminant is positive ( > 0), there are 2 real solutions.
If the discriminant is = 0, there is 1 real repeated solution.
If the discriminant is negative (< 0), there are 2 complex solutions (but no real solutions).
