Answer:
Yes. They're equivalent.
Step-by-step explanation:
1/8-10(3/4-3/8x)+5/8x
1/8-30/4+30/8x+5/8x
1/8-60/8+35/8x
-59/8+35/8x
factor out -1/8
-1/8(59-35x)
I think it is 14LB (pounds)
Answer:
A. How much flour did she use for both cakes?
1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
3 17/20 lb
Step-by-step explanation:
Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake
A. How much flour did she use for both cakes?
We solve the above question by adding up the pound of flour used for both cakes.
2/5lb Of flour + 3/4lb Of flour
Lowest common denominator = 20
= 8 + 15/20
= 23/20
= 1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
This is calculated as:
5 lb - 1 3/20 lb
= 3 17/20 lb
Answer:
A. 
Step-by-step explanation:
The question seems to be incomplete. However, we'll make the following assumption.
Pythagoras theorem states that:
Substitute values for Hypothenuse, Opposite and Adjacent.
This gives

From the list of given options.
A answers the question
Answer:
57.1
Step-by-step explanation:
Perimeter Formula: P = 2l + 2w
Simply plug in what we know and solve:
269.4 = 2l + 2(77.6)
269.4 = 2l + 155.2
114.2 = 2l
l = 57.1
