Hi Grace!
4p + 12 - 3q - 4p - 18 + 6q
Combine like terms
4p - 4p + 12 - 18 - 3q + 6q
= -6 + 3q
The correct answer is option D
Answer:
Answer will be
Step-by-step explanation:
We have to perform the calculation without changing into decimal
can be written as
So
Now taking common
<h3>
Answer: false</h3>
Work Shown:
s = false
p = true
r = false
-p = false, which is the opposite of statement p
s or -p = false or false = false
The result of an 'or' operation is false only when both parts are false; otherwise, it is true
(s or -p) or r = false or false = false
(s or -p) or r = false
Answer:
I haven't done this in a while but I'm pretty sure it's C.
Step-by-step explanation:
A triangle has to have 180 degrees. angle a and c are congruent. angle b is slightly smaller. therofore, istead of all the angles biegh 60, a and c are 65 thus leaving angle b 50 degrees
Using a system of equations, it is found that Debbie worked 45 hours during the week.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount of hours worked by Juan.
- Variable y: Amount of hours worked by Debbie.
Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:
9x + 9y = 765
Simplifying the expression by 9:
x + y = 85 -> x = 85 - y.
Debbie worked five hours more than juan during the week, hence:
y = x + 5.
Since x = 85 - y, we replace in the expression:
y = 85 - y + 5.
2y = 90.
y = 45.
Debbie worked 45 hours during the week.
