Find the value of x. 984 (149-x) 128 2x+4)
You have a pentagon. In order to determine the value of x for the given expression, of the measure of the angles, take into account that the sum of the interior angles of a pentagon is 540°.
Then, by using the given expressions you have:
(98) + (149 - x) + (2x + 4) + (114) + (128) = 540
To solve for x, proceed as follow:
(98) + (149 - x) + (2x + 4) + (114) + (128) = 540 eliminate parenthesis
98 + 149 - x + 2x + 4 + 114 + 128 = 540 simplify like terms left side
493 + x = 540 subtract 493 both sides
x = 540 - 493
x = 47
Hence, the value of x is x = 47
MAKE CONNECTIONSKatie is twice as old as her sister Mara. The sum of their ages is 24. Write a one-variable equation tosituation
Answer
3x = 24
Explanation
Let sister Maria's age be represented by x.
Katie is twice as old as her sister Mara
So Katie's age will be 2x.
If the sum of their ages is 24, it implies x + 2x =24
Therefore, a one-variable equation to the situation will be: 3x = 24

Can you provide an example of a number that is a perfect square
ANSWER
9
EXPLANATION
A perfect square is a number that can be expressed as the product of two equal integers.
For example, 9 is a perfect square because it can be expressed as the product 3 x 3 = 3² - which are two equal integers.

At the North Carolina Zoo there is a bucket that contains food for the gorillas and the grizzly bears. The gorilla food weighs 5.384 kg. The gorilla food weighs 0.796 kg more than the grizzly bear food. How much food for both gorillas and grizzly bears are in the bucket?
The food for both gorilla and grizzly bear in the bucket is 9.972 kg.
Given, at the North Carolina Zoo there is a bucket that contains food for the gorillas and the grizzly bears.
The gorilla food weighs 5.384 kg. The gorilla food weighs 0.796 kg more than the grizzly bear food.
Let the weight of the grizzly bear food be x,
According to the question,
weight of gorilla food = weight of grizzly bear food + 0.796 kg
5.384 = x + 0.796
x = 5.384 - 0.796
x = 4.588
So, the food for both gorilla and grizzly bear in the bucket is 9.972 kg.
Hence, the food for both gorilla and grizzly bear in the bucket is 9.972 kg.

We are told that the maximum amount to spend is $80 and that there is a 7.5% sales tax. If N is the amount we are going to spend then we need to have into account that we need to add the 7.5% of N and that should be at least equal to $80.

The value of 'w' for the two parallel lines are cut by the transversal is 52.
What is meant by the supplementary angles?The term "supplementary angles" refers to a pair of angles which always add up to 180°. These two perspectives are known as supplements. When supplementary angles are combined, they form a straight angle (180 degrees). In other words, so unless Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary.For the given question
Two parallel lines are cut by the transversal.
Then,
w + (3w -28) = 180 (same side exterior angle of the traversal are supplementary)
Solve the equation;
4w - 28 = 180
4w = 208
w = 208/4
w = 52
