First, let's call the two numbers we are looking for:

Now, we can write:

(Equation 1) n+m=59

(Equation 2) n=m+23

first substitute n since it is (m+23)

(m+23)+m=59

m+23+m=59

2m+23=59

now subtract 23 from both sides since we want it to be zero in the left side

2m+23-23=59-23

2m=36

m=36/2=18

the smaller number is 18

now we can substitute 18 in the second equation

n=18+23=41

the bigger number is 41 and the smaller number is 18

Answer:

18, 41

Step-by-step explanation:

simultaneous equation

x + y = 59

x - y = 23

subtract both equations

2y = 36

y = 18

x = 41

The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacter
Drupady [299]

Answer:

  • f(x) = 50000*2^x
  • 3 days

Step-by-step explanation:

<u>Given:</u>

  • Initial amount of bacteria = 50000
  • Growth rate = 2 times a day

<u>Required equation:</u>

  • f(x) = 50000*2^x

<u>Solve for x:</u>

  • 400000 = 50000*2^x
  • 2^x = 400000/50000
  • 2^x = 8
  • 2^x = 2^3
  • x = 3

After 3 days bacteria numbers will reach 400000

The local grocery store has sorted apples by size. The distribution is approximately normal. The large apples have a mean diamet
NikAS [45]

Answer:

0

Step-by-step explanation:

Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)

Which equation illustrates the identity property of multiplication? (a + bi) × c = (ac + bci) (a + bi) × 0 = 0 (a + bi) × (c + d
labwork [276]

Answer:

(a + bi) \times 1 = (a + bi)

Step-by-step explanation:

The identity property means that whatever you put in is whatever comes out. Notice that if we multiply 1 with any number, we get that number back. So multiplying by 1 is the identity property of multiplication.
