Answer:
Jim carried 4 grocery bags.
Step-by-step explanation:
16 is the total, and if you divide that up by 4, you get 4 (you divide by 4 because it is in fourths). Because Byron carried 3/4's, you multiply four by three to get twelve. There is only one more fourth to complete the whole to get to 16, so Jim is carrying four bags.
To check this, we can take Byron's 12 bags (3/4), and subtract that from 16 (4/4):
16-12=4 (1/4), so our answer is correct
1 and 1/3 is 3/3 and 1/3 so is 4/3 then
4/3 -5/6 they have to have the same denominators so multiply the first fraction with 2/2
(4•2/3•2)-5/6=(8/6)-(5/6)= (8-5)/6=3/6 that you can simplify as 1/2
Answer:
The generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
Step-by-step explanation:
We are given the following from what she knows
m∠3=2⋅m∠1... 1
m∠2=2⋅m∠4 ... 2
m∠2+m∠3=360 ... 3
From what is given, we can substitute equation 1 and 2 into equation 3 as shown:
From 3:
m∠2+m∠3=360
Substituting 1 and 2 we will have:
2⋅m∠4 + 2⋅m∠1 = 360
Factor out 2 from the left hand side of the equation
2(m∠4+m∠1) = 360
Divide both sides by 2
2(m∠4+m∠1)/2 = 360/2
m∠4+m∠1 = 180°
Since the sum of two supplementary angles is 180°, hence the generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
