To get the answer first we have to find full numbers.
We can use proportion
2/3 ----------------------- 375
1 -------------------------- x
Crossmultiply now
2/3*x=375 /:2/3
x=
x=

- its the answer A)
Now we have to find how much were originally on the card.
To get the answer we can just multiply 562 times 1/4.
562*1/4=140 - its the asnwer B)
Answer:
x = 12/13
BC = 140/13
Step-by-step explanation:
If A is the mipoint of BC, then AB is half of BC.
AB = BC / 2
8x − 2 = (3x + 8) / 2
16x − 4 = 3x + 8
13x = 12
x = 12/13
BC = 3x + 8
BC = 3 (12/13) + 8
BC = 36/13 + 104/13
BC = 140/13
Answer:
Step-by-step explanation:
<u>Substitute:</u>
<u>Then the expression becomes:</u>
The result is 1 regardless the value of x other than 1.
Answer:
Step-by-step explanation:
if there are two numbers a and b.then
1. a+b=b+a ,commutative under addition.
2. ab=ba,commutative under multiplication.
If there are three numbers a,b,c then
1. a+(b+c)=(a+b)+c,associative under addition.
2.
a×(b×c)=(a×b)×c ,associative under multiplication.
