Answer: x = 9

Step-by-step explanation:

The sum of three interior angles of a triangle is 180°.

(9x - 3) + (6x) + 48° = 180°

9x - 3 + 6x + 48 = 180

15x + 45 = 180

15x = 135

x = 9

For every quarter he spends, Reggie receives 50 food pebbles to feed the fish. Reggie has thrown 350 food pebbles into the fish

deff fn [24]

Answer:

7 quarters are spent for throwing 350 food pebbles in pond.

Step-by-step explanation:

Given:

Reggie receives 50 food pebbles for every quarter he spends.

Number of food pebbles he has = 350

Let the number of quarters spent for 350 pebbles be 'x'.

Now, using proportion and cross multiplication method, we can find 'x'.

1 quarter is equivalent to 50 pebbles thrown in pond.

So, 'x' quarters is equivalent to 350 pebbles thrown in pond.

$\frac{1}{50}=\frac{x}{350}\\\\Cross\ multiplying\\\\50x=350\\\\x=\frac{350}{50}\\\\x=7$

So, 7 quarters are spent for throwing 350 food pebbles in pond.

Select the correct answer. Evaluate the following expression when x = -4 and y = 4. A. B. C. D.

andriy [413]

The value of given expression when x=-4 and y=4 is 1250.

The expression is missing in the question which is $\dfrac{x^6-x}{4y}$ .

We have to solve it for x= -4 and y = 4.

Now putting the value of x and y we get,

$\dfrac{x^6-x}{4y}=\dfrac{(-4)^6-(-4)}{4}$

$\dfrac{x^6-x}{4y}=\dfrac{4096+4}{4}$

$\dfrac{x^6-x}{4y}=1250$

Hence the value of given expression when x=-4 and y=4 is 1250.
