Answer:

x=16

Step-by-step explanation:

7(x + 2) = 6(x + 5)

Expand:

7x+14=6x+30

Subtract 14 from both sides:

7x+14-14=6x+30-14

7x=6x+16

Subtract 6x from both sides:

7x-6x=6x+16-6x

x=16

A yurt, or circular tent, has a radius of 3 m. What is the area of the floor of the yurt? Use 3.14 for π . Enter your answer as
Andrei [34K]

The answer would be 28.26.

The reason this would be the answer is because radius is half of a circle and diameter goes through the entire circle the formula for this problem would be

Circumference= \pir^{2}

and the tent has radius of 3m which means we have to multiple 3 × 3 to get 9m and then we would multiply 9 × 3.14 = 28.26

A store sold 50 copies of a magazine for $150. Each copy of the magazine costs the same. Which equation and set of ordered pairs
Goryan [66]

Answer:

Option a. Y=3x

Step-by-step explanation:

Let us use cross multiplication method.

Let the cost of 1 magazine be x.

No. of copies                               Cost

1)50                                                $150

2)1                                                      x

50x=150 x 1               equation(1)

x=150/50

x=$3

Now see equation (1),

150=50x

150=50 x 3

Here let us represent the cost as y and no. of copies as x.

Y=3x

Therefore, a. Y=3x is the right answer.

Thank you!

Person A can paint the neighbors house 2 times as fast as Person B. The year A and B worked together, it took them 2 days. How l
seraphim [82]

Answer:

A can paint in 3days and B in 6 days

Step-by-step explanation:

From the question we were told

Person A can paint the neighbors house 2 times as fast as Person B

Let A only paint the neighbors house in X days

Let B only paint the neighbors house in 2X days

If we express the given information from the question in terms of fraction we have,

1/X + 1/2X = 1/2

3/2X = 1/2

if we cross multiply we have

6= 2X

X= 6/2

X= 3

Then A can paint the house in 3 days and B in 2(3)= 6days.

What are the solutions to the equation (x – 2)(x + 5) = 0?
nataly862011 [7]

A product of two (or more) factor can be zero if and only if at least one of the factors is zero.

In other words, you cannot multiply two non-zero real numbers, and have zero as a result.

So, if we want the product of these two factors to be zero, at least one of them has to be zero.

The first factor is zero if

x-2 = 0 \iff x=2

The second factor is zero if

x+5 = 0 \iff x=-5
