Answer:
Step-by-step explanation:
20. First find the values of the numbers being added.
These numbers have a common denominator, so you can add the numerators
27 + 25 = 52
so the number comes out to
to simplify, divide the numerator and denominator by 4.
So the final fraction becomes
However the question doesn't have this answer and now I am confused. I assumed that the expression was but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
21.
4x + 8x + 7 + 4
Combine the like terms to get the expression
12x + 11 the answer is c.
The rate of change is the same as the slope...u can use the slope formula : (y2 - y1) / (x2 - x1), with 2 sets of points...or....according to ur graph, they want to know how many miles u can go for 1 hr. y/x.....60/1....so they can go 60 miles in 1 hr...60/1 is ur unit rate.
Answer:
6
Step-by-step explanation:
2 goes into 6 evenly so two times three equals six so you multiply 1 by three and it gives you 3/6
If they are vertical, there magnitude would be equal.
3x = x + 40
3x - x = 40
x = 40/2
x = 20
So, m<4 = 3(20) = 60
Hope this helps!
Step-by-step explanation:
x ÷ 3 - 7 = -2
x - 7 = -2 × 3
x - 7 = -6
x = -6 + 7
x = 1
