if a puppy weighs 59 oz in 9 weeks how much did I gain if it was 5 oz at birth

Answers

Answer:

54 oz (Which would mean 6 oz/week)

Step-by-step explanation:

To get the answer of 54 oz, subtract 5 oz from 59 oz

D = F - S

D = 59 - 5

D = 54

(For the rate, divided 54 oz gained in 9 weeks)

UR = D/T

UR = 54/9

UR = 6 oz/week

Answer:

54 oz

Step-by-step explanation:

You just do 59-5. The 9 weeks is useless but if its asking for each week, its 6, otherwise its 54.

solve for n: 14.23n - 15 = 41.92

Answers

Hopefully this helps
Answer: n = 4

Steps for Solving Linear Equation

14.23n−15=41.92

Add 15 to both sides.

14.23n=41.92+15

Add 41.92 and 15 to get 56.92.

14.23n=56.92

Divide both sides by 14.23.

n= [tex]\frac{56.92}{14.23}[/tex]

​Expand  [tex]\frac{56.92}{14.23}[/tex]  by multiplying both the numerator and the denominator by 100.

n= [tex]\frac{5692}{1423}[/tex]

Divide 5692 by 1423 to get 4.

n=4

What is the smallest whole number that is equal to seven times the sum of its digits?

Good Luck!!! First Right Asnwer gets brainliest!!!

Answers

Answer:

21

Step-by-step explanation:

21.

Explanation:

The two-digit number ab stands for 10a + b since the first digit represents 10s and the second represents units. If 10a + b = 7(a + b), then 10a + b = 7a + 7b, and so 3a = 6b, or, more simply, a = 2b. That is, the second digit must be twice the first. The smallest such number is 21.
