Distributive Property: 2(5c-7)=1

Mathematics
1 answer:
mezya [45]3 years ago
6 0
The formula for distributive property is:

a(b + c) = ab + ac

Steps:

so, 2(5c - 7) = 1

1.) 2(5c) - 2(7) = 1

10c - 14 = 1

2.) Add 14 to both sides:

10c - 14 + 14 = 1 + 14

3.) Simplify:

10c = 15

4.) Then, divide both sides by 10:

10c/10 = 15/10

5.) Simplify:

c = 3/2  
is the answer.



Hope this helped you solve this question!!!

Find the volume of the cylinder if the height is 3 mm and the diameter is 40 mm. Leave the answer in terms of it.
KiRa [710]

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.

Step-by-step explanation:

Height of cylinder = 3mm

Diameter of cylinder = 40mm

Volume of cylinder = ?

The formula used to find Volume of cylinder is:

Volume = \pi r^2h

Putting values in the formula:

Since we need radius,

radius = diameter/2

radius = 40/2

radius = 20 mm

So,

Volume = \pi r^2h\\Volume = 3.14*(20)^2*3\\Volume = 3.14*400*3\\Volume= 3769.91 or \,\,\,Volume\approx 3770\,\,cubic\,\,millimeters

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.

Write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Levart [38]

Answer:

y = 3x - 14

Step-by-step explanation:

Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.

Plug in the slope and given point into y = mx + b, then solve for b:

y = mx + b

4 = 3(6) + b

4 = 18 + b

-14 = b

Plug in the slope and y intercept into y = mx + b

y = 3x - 14

So, the equation of the line is y = 3x - 14

13 weeks is what percent of 52 weeks
Aleonysh [2.5K]
To get a number as a percent of another, you divide and multiply by 100, so here you would have (13/52)*100=.25*100=25, making your answer 25%.
