Answer:

x = 13/5, 11/15

Step-by-step explanation:

11x = 15

x = 11/15

5x = 13

x = 13/5

Answer:

x = 15/11 or x = 13/5

Step-by-step explanation:

I'm going to assume that the expression is equal to 0:

(11x - 15)(5x - 13) = 0

By the zero identity, if either 11x - 15 or 5x - 13 is equal to 0, that will make the equation true. So, let's set each one equal to 0:

11x - 15 = 0 ⇒ 11x = 15 ⇒ x = 15/11

AND

5x - 13 = 0 ⇒ 5x = 13 ⇒ x = 13/5

Thus, x = 15/11 or x = 13/5.

Hope this helps!

What is angle J and angle R?

m_a_m_a [10]

The letters in one triangle are in the same location as the second triangle:

Triangle 1 is written as HIJ and triangle 2 is written as RTS

This means H = R, I = T and J = S

Angle J = ANgle S which is given as 89 degrees

Angle J = 89

Angle R = ANgle H which is given as 30 degrees

Angle R = 30

Which of the following is the missing reason? Statements Reasons two thirds times x plus 7 equals negative 5 Given 2x 21 = â’15

pentagon [3]

The correct option is B. Distributive property

Given,

$\frac{2}{3} x+7=-5\\$

On solving the above equation,

multiplying both sides by 3 we, get

$2x+21=-15$

now subtracting 21 from both the sides,

$2x=-36\\$

dividing both the sides by 2 we get,

$x=-18$

Since in the above steps we follow all the giving property except the distributive property.

Hence the correct option is B. Distributive property.

you deposit $1,200 in a bank account. Find the balance after 4 years in the account pays 3.5% annual interest compounded monthly

photoshop1234 [79]

Answer:

The balance after 4 years would be $1,380.05.

Step-by-step explanation:

Given that you deposit $ 1,200 in a bank account, to find the balance after 4 years in the account pays 3.5% annual interest compounded monthly, the following calculation must be performed:

1,200 x (1 + 0.035 / 12) ^ 4x12 = X

1,200 x 1.00291666 ^ 48 = X

1,380.05 = X

Therefore, the balance after 4 years would be $1,380.05.

Find two positive real numbers whose product is a maximum. the sum is 80

Eduardwww [97]

Let's say the numbers are "a" and "b"

thus $\bf y=ab\qquad 
\begin{cases}
a+b=80\\
b=80-a
\end{cases}\implies y=a(80-a)\implies y=80a-a^2\\\\
-----------------------------\\\\
\cfrac{dy}{da}=80-2a$

set the derivative to 0, and check the critical points, there's only one anyway

and do a first-derivative test, to see if it's a maximum
