1/7 x X =1 <br> X x 1/11=1<br> 1 divided by 1/5=

guajiro [1.7K]

Answer:

x = 7
x = 11
5

Step-by-step explanation:

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

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

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

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

◇◇•◇◇

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

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

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

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

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

♤♤•♤♤

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

$1 \times 5$

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

write the point slope form of the equation for a line that passes through the point 3, 1 and is parallel to the line y=3x+3

Galina-37 [17]

Answer:

y=3x-8

Step-by-step explanation:

If the line is parallel to y=3x+3, that would mean that they would have the same slope of 3. Then, once you plug it back into the equation along with the point given, you would get 1=3(3)+b. Solve from there, and you get b= -8. In conclusion, your point slope formula comes out to be y=3x-8.

Hope this helps! :)

A small box of cereal contains 10 cups of cereal. A medium box of the same cereal contains 30% more cereal than the small box. H

mario62 [17]

Answer:

13 cups

Step-by-step explanation:

If the small box has 10 cups, then:

<u> (small) </u> <u> 10 cups </u> = <u> 100% </u>

(medium) x cups = 130%

Now, cross multiply:

10 (130) = x (100)

1300 = 100x

x = 13

Another way to solve this is by turning 30% into a decimal:

30/100 = 0.3

10 (0.3) = 3

Now you have 30% of the 10 cups, but you need <u>30% more</u><em> </em>than the small box, so:

10 + 3 = 13 cups
