Answer:</h3>
- A) p = 5, one solution
- B) no solutions
- C) infinite solutions
<h3>
Step-by-step explanation:</h3>
A) Add 19-5p to each side of the equation:
... 10 = 2p
... 5 = p . . . . . divide by the coefficient of p
B) Subtract 5p from both sides of the equation:
... -9 = -19 . . . . . there is <em>no value of p</em> that will make this true. (No solution.)
C) Subtract 5p from both sides of the equation:
... -9 = -9 . . . . . this is true for <em>every value of p</em>. (Infinite solutions.)
Answer:
30p
Step-by-step explanation:
10-6.1=3.9 POUNDS was the total cost of everything
6*0.25=1.5 pounds (was what he paid for the 6 apples)
3.9-1.5=2.4 pounds (was what he paid for the 8 pears)
2.4/8=0.3 pounds (the price per pear)
8.715
2.49 x 3 1/2 = 8.715
Answer: 46.7
Step-by-step explanation:
Place value are very useful to compare given numbers. Place value gives ideas on how big the number is and helps you compare easily what is greater and lesser.
Let’s use the given number:
50 => 50 has 2 digit whole number, which means it has a place value of tens
=> 5 tens and 0 ones.
5000 => is a 4 digit whole number, which means it as a place value of 5000
=> 5 thousands 0 hundreds, 0 tens and 0 ones.
5000 is 100 times greater than 50.
=> 50 x 100 = 5000
