Answer:

p = 36/5, or p = 7  1/5

Step-by-step explanation:

Next time, please include the instructions.

I think the goal is to solve this equation for p.

Let me write this equation as

(5/8)(p - 4) = 2

We can get rid of the fractional coefficient (5/8) by multiplying both sides of this equation by (8/5).  This gives us:

p - 4 = (8/5)(2).

Let's eliminate fractions again.  To do this, multiply all 3 terms by 5.  We'll then have:

5p - 20 = 16

Solve for p.  To do this, add 20 to both sides:

5p = 36

so that     p = 36/5, or p = 7  1/5

Please help me answer question 12

Answer:

x = 81, y = 68, z = 99

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left, then

x = 180 - (36 + 63) = 180 - 99 = 81

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle on the right, thus

13 + y = x , that is

13 + y = 81 ( subtract 13 from both sides )

y = 68

Consider the triangle on the right

z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99

Select the correct answer.
Volgvan

Answer:

B

Step-by-step explanation:

If C is the correct answer and if the final result is multiplied out, where does the minus sign in a^4 - b^4 come from? All pluses don't make a minus. A is incorrect.

If D is correct, then a^2 - b^2 should be further factored producing a different kind of answer, like (a + b)^2(c-d)^2 which is not the same as a^4 - b^4. So D is not correct.

The first step in factoring a^4 - b^4 is (a^2 + b^2)(a^2 - b^2) A doesn't lead you anywhere. A is incorrect. The answer must be B.

a^4 - b^4 = (a^2 -  b^2)(a^2 + b^2)  The first term factors.

a4 - b^4 = (a + b)(a - b) (a^2 +b^2)

2. Currently, Yamir is twice as old as Pato. In three years, the sum of their ages will be 30. If Pato's current age
lianna [129]

Given:

Yamir is twice as old as Pato.

In three years, the sum of their ages will be 30.

Pato's current age is represented by a.

To find:

The equation that could be used to correctly solve for a.

Solution:

We know that, Pato's current age is represented by a, then

Yamir's age = 2a

After three years,

Pato's age = a+3

Yamir's age = 2a+3

In three years, the sum of their ages will be 30.

(a+3)+(2a+3)=30

(a+2a)+(3+3)=30

a+2a+6=30

Therefore, the correct option is 2.
