1 answer:

3 0

If 1 of ur factors is 9...and the sum of ur factors is 13....then ur other factor is (13 - 9) = 4

so u have 2 factors, 9 and 4, and u r the product, then u r (9 * 4) = 36 <==

solve the system of equations below by graphing both equations with a pencil and paper. what is the solution y = x - 1 y = 1/2x

Elan Coil [88]

Answer:

(4,3)

Step-by-step explanation:

$(x-1) = \frac{1}{2}x +1$

$(x-\frac{1}{2}x)-(-1+1)=(\frac{1}{2}x-\frac{1}{2}x)+(1+1)$

$(\frac{1}{2}x/\frac{1}{2})=(2/\frac{1}{2})$

$x=4$

$y=(4)-1$

$y=3$

$y=\frac{1}{2}(4)+1$

$y=2+1$

$y=3$

A particular convex pentagon has two congruent, acute angles. The measure of each of the other interior angles is equal to the s

NNADVOKAT [17]

1. First, you must apply the formula for calculate the sum of the interior angles of a regular polygon, which is shown below:

(n-2) × 180°

"n" is the number of sides of the polygon (n=5).

2. Then, the sum of the interior angles of the pentagon, is:

(5-2)x180°=540°

3. The problem says that the measure of each of the other interior angles is equal to the sum of the measures of the two acute angles and now you know that the sum of all the angles is 540°, then, you have:

α+α+2α+2α+2α=540°

8α=540°

α=540°/8

α=67.5°

4. Finally, the larger angle is:

2α=2(67.5°)=135°

5. Therefore, the answer is: 135°

Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizz

Karolina [17]

We have been given that Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizza. We are asked to find the number of full pizzas that Morgan can make with the amount of cheese she has.

To solve our given problem, we will divide total amount of cheese by amount of cheese used to make each pizza.

$\text{Number of pizzas}=1\frac{7}{8}\div \frac{1}{5}$

$\text{Number of pizzas}=\frac{15}{8}\div \frac{1}{5}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction.

$\text{Number of pizzas}=\frac{15}{8}\times \frac{5}{1}$

$\text{Number of pizzas}=\frac{75}{8}$

$\text{Number of pizzas}=9\frac{3}{8}$

We are asked to find the number of full pizzas and we can see that Morgan can make 9 full and $\frac{3}{8}$ pizzas.

Since there are 9 full pizzas, therefore, Morgan can make 9 full pizzas with the amount of cheese she has.
