When solving for x, we know that the sum of a polygon's interior angles will always comply with the formula. The formula to solve for the sum of the interior angles is: (n - 2)(180).

For this specific problem, all we need to do is plug in 6 for n. The new equation will be (4)(180).

4*180 = 720. Therefore, the sum of the interior angles would be 720 degrees, however, we can't stop there since we're solving for x.

The next step is to add up all of the other angles.

160 + 75 + 132 + 113 + 108 + x = 720.

x + 588 = 720

*Subtract 588 from both sides*

x = 132

Kim is 5 years older than her brother Jack. If the sum of their ages is 21, find each of their ages.

yarga [219]

9514 1404 393

Answer:

Kim is 13
Jack is 8

Step-by-step explanation:

Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...

k + (k -5) = 21

2k = 26 . . . . . . . add 5, collect terms

k = 13 . . . . . . . . . divide by 2; Kim's age

k -5 = 8 . . . . . . . Jack's age

Kim is 13; Jack is 8.

By what number must 566 be divided so as to give a quotient 15 and a remainder 11? (with steps)

olchik [2.2K]

Answer:

37

Step-by-step explanation:

we would had to call the number needed a random value or call it x but

let's do the calculation backward to ease things up

(566 - 11) ÷15 ➡ 555 ÷ 15 = 37

The average weight of 3 containers A,B and C is 3.2kg. Container A is twice as heavy as container B. Containers B is 400 g heavi

dlinn [17]

Answer:

The weight of container C is 2.1kg.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the weight of container A.

y is the weight of container B.

z is the weight of container C.

The average weight of 3 containers A,B and C is 3.2kg.

This means that the total weight is 3*3.2 = 9.6kg. So

$x + y + z = 9.6$

Container A is twice as heavy as container B.

This means that $x = 2y$ .

Containers B is 400 g heavier than container C.

400g is 0.4kg. So

This means that $y = z + 0.4$ , or $z = y - 0.4$

Replacing y and z as functions of x in the first equation:

$x + y + z = 9.6$

$2y + y + y - 0.4 = 9.6$

$4y = 10$

$y = \frac{10}{4} = 2.5$

Container C

$z = y - 0.4 = 2.5 - 0.4 = 2.1$

The weight of container C is 2.1kg.
