Cam was bom weighing 8.6 pounds. Every day, he gained the same amount of weight. After 30 days, he weighed 14.9

guajiro [1.7K]

Answer:

So I'm not entirely sure about this one, but I believe he gained 0.21 pounds each day for 30 days

Step-by-step explanation:

Since Cam was born weighing 8.6 pounds and after 30 days weighed 14.9, subtract 14.9-8.6 to find how much he gained.

14.9 - 8.6 = 6.3

Now that we know how much he gained, we have to find out how much he gained per day for 30 days. To do this, divide 6.3 by 30

6.3 / 30 = 0.21

To make sure this answer is correct, multiply 0.21 by 30 and add that to 8.6. It should equal 14.9.

I hope this helps!

1/7 x X =1 X x 1/11=1 1 divided by 1/5=

guajiro [1.7K]

Answer:

x = 7
x = 11
5

Step-by-step explanation:

$\frac{1}{7} \times x = 1$

$7 \times \frac{1}{7} x = 7 \times 1$

$7 \times \frac{1}{7} x = 7$

$\boxed{\green{x = 7}}$

◇◇•◇◇

$x \times \frac{1}{11} = 1$

$\frac{1}{11} x = 1$

$11 \times \frac{1}{11} x = 11 \times 1$

$11 \times \frac{1}{11} x = 11$

$\boxed{\green{x = 11}}$

♤♤•♤♤

$1 \div \frac{1}{5} = 1 \times \frac{5}{1}$

$1 \times 5$

$\boxed{\green{= 5}}$
