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

1 answer:

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!!!

Frank can build a fence in twice the time it would take Sandy. Working together, they can build it in 7 hours. How long will it take each of them to do it alone?

Answer

If Frank and Sandy can build the fence in 7 hours, they must be building

of the fence every hour.

Now, let the amount of time it takes Sandy be

hours so that Frank takes

hours. Sandy can build

of the fence every hour and Frank can build

of the fence every hour.

We now have the following equation to solve.

10.50

Thus, Sandy takes

10.50

hours and Frank takes

hours.

A symbol used to name one or more parts of a whole or a set, or a location on a number line is a?

Answer:

Fraction

Step-by-step explanation:

Fraction is a symbol that represents a part of a whole. It consists of a numerator and a denominator. The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.

Examples of Fraction: $\frac{1}{2}$ , $\frac{2}{7}$ and $\frac{5}{8}$ .

In the first example, $\frac{1}{2}$ , 1 is the numerator, while 2, is the denominator.

Additional Information

When the numerator is smaller than the denominator, the fraction is called "proper fraction." On the contrary, when the numerator is bigger than the denominator, the fraction is called "improper fraction."

A race car Travel 100 feet in five seconds at this rate of speed how many feet will the race car travel in a minute?

Dafna11 [192]

Convert minute to seconds (1 minute = 60 seconds), set up a proportion, cross multiply, and solve.

Proportion: $\frac{100 ft}{5 sec}$ = $\frac{x}{60 sec}$

Cross multiply: 60 · 100 = 5 · x

Solve (divide both sides by 5): 1200 = x

Answer: 1200 ft

What is 9 plus 10???

Anon25 [30]

Answer:

Here’s legitimate proof that 9+10=21

(9 + 10) (base x) = 21 (base y)

9(1) + [1(x) + 0(1)] = 2(y) + 1

Simplify and solve for y:

2y = 8 + x

y = 4 + x/2

Since we have number bases, we want x and y to be positive integers. The term x/2 requires that x be a positive even number.

Also since 9 is in base x, we have x ≥ 10, as the digit 9 would not be used for a base 9 or smaller.

Thus we have the pairs of solutions:

x = 10, so y = 9

x = 12, so y = 10

x = 14, so y = 12

…

x, y = 4 + x/2 … Therefore 9+10=21!
