Multiplying an odd number of negative factors equals a negative

-4/7 x 3/5 x 7/3

Reduce the numbers with greatest common divisor

-4/7 x 1/5 x 7

calculate the product

-4 x 1/5 = - 4/5

-4/7 x (-3/5) x (-7/3) x (-4/5) x (-7/3)

Multiplying an odd number of negative factors equals a negative

-4/7 x 3/5 x 7/3 x 4/5 x 7/3

Reduce the numbers with greatest common divisor 3

-4/7 x -1/5 x 7 x 4/5 x 7/3

Reduce the numbers with greatest common divisor

-4 x 1/5 x 4/5 x 7/3

calculate product

-112/75

-1 37/75

What is the area of this figure? 28 yd² 40 yd² 52 yd² 64 yd²

Lubov Fominskaja [6]

Answer: A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

"B" is the answer.

I hope this helps!

The Martinez family went to the movies and paid $60 for two adult tickets and three children’s tickets. The Wright family consis

Pepsi [2]

Answer:

a = $13.5

Step-by-step explanation:

Let a = adult tickets

Let c = children tickets

Translating the word problem into an algebraic equation;

For the Martinez family;

2a + 3c = $60

For the Wright family;

3a + 5c = $95.5

Thus, the simultaneous equations are;

$2a + 3c = $60$ ..........equation 1

$3a + 5c = $95.5$ .........equation 2

We would use substitution method to solve;

From equation 2, we make a the subject of formula;

3a = 95.5 - 5c

a = (95.5 - 5c)/3

Substituting the value of "a" into equation 1, we have;

2[(95.5-5c)/3] + 3c = 60

Multiplying all through by 3;

2(95.5 - 5c) + 9c = 180

191 - 10c + 9c = 180

191 - c = 180

c = 191-180

c = $11

To find the value of a;

2a +3c = 60

Substituting the value of "c" into the equation, we have;

$2a + 3(11) = 60$

$2a + 33 = 60$

$2a = 60 - 33$

$2a = 27$

$a = \frac{27}{2}$

a = $13.5

Therefore, the cost of an adult movie ticket is $13.5.
