3/2 and 9/10. Look at the denominators. 2 times what number equals 10. That number would be 5. So if you multiply the first fractions denominator by 5 you get 10. Do the same to the top. you get a new fracrion which is 15/10. Add normally. 15/10 + 9/10 = 24/10. In lowest terms it is 2 2/5 (2 wholes and 2 out of 5)
Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
In this problem we have

This is the equation of a line in slope intercept form
where
---> is the slope
---> is the y-intercept
therefore
Any equation with a slope 7 and y-intercept different of 5 could be the equation of the line k
Note If the slope is 7 and the y-intercept is 5 we have identical lines not parallel lines
Answer:
D
Step-by-step explanation:
d = rt so to isolate r you divide both sides by t, leaving you with r=d/t
its basically speed=distance/time, or s=d/t if that's more farmiliar to you
Answer:
1
= -----------
6(x + 7)
Step-by-step explanation:
3x - 21 x^2 - 49
----------- ÷ -------------
18x - 18 x - 1
3x - 21 x - 1
----------- × -------------
18x - 18 x^2 - 49
Factor the top left:
3x - 21 = 3(x - 7)
Factor the bottom left:
18x - 18 = 18(x - 1)
Factor the new bottom right:
x^2 - 49 = (x + 7)(x - 7)
Multiply and simplify the faction:
3(x - 7) x - 1
----------- × -----------------
18(x - 1) (x + 7)(x - 7)
1
= -------------
6(x + 7)
Answer:
B - Top Right
Step-by-step explanation:
3x + 6y = -57
-3x - 6y = 57
I hope this helps
