Answer:
2/5 > 1/4
Step-by-step explanation:
2/5 = 4/10 = 0.4
1/4 = 0.25
0.4 > 0.25
2/5 > 1/4
Let r = # of red marblesLet 2r = # of blue marbles ... (1/2 as many red as blue, means blue is twice the red)Let r+8 = # of yellow marbles ... (8 more than the red) Total is 56 ... our equation is r + 2r + r + 8 = 56 4r + 8 = 56 4r = 56 - 8 4r = 48 r = 12 There are 12 red marbles.There are 24 blue marbles.There are 20 yellow marbles.
Answer:
In the given two column proof two sides and included angles are equal.
Triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles .In the figure sides BD≅BD , AB≅ BC and <ABD ≅,BDD Therefore triangle ABD and triangle CBD are congruent by SAS property of congruence.
Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
