Answer:
x = 25
y = 21
Step-by-step explanation:
4x + 10 + 3x - 5 = 180° because these two angles makes a straight line
7x + 5 = 180° subtract 5 from both sides
7x = 175° divide by 7
x = 25
2y + 28 + 4y + 26 = 180° because the sum of these angles is equal to a straight line's measure
6y + 54 = 180° subtract 54 from both sides
6y = 126 divide both sides by 6
y = 21

Inequalities in the explanation
Step-by-step explanation:
Inequalities
Is a relation that makes a non-equal comparison between two mathematical expressions using comparators as >, <, ≤, and ≥, among others.
Some usual operations performed in equations cannot be done in the same way in inequalities, especially multiplying or dividing by negative numbers. When we need to multiply or divide by a negative number, the inequality sign must be flipped.
Let's start off with the inequality
4>-3
a) Add 3 to each side:
4+3>-3+3
7>0
b) Subtract 2 from each side:
4-2>-3-2
2>-5
c) Multiply each side by 2:
2*(4)>2*(-3)
8>-6
d) Multiply each side by -3. We must flip the sign:
-3(4)<(-3)(-3)
-12<9

What does m represent in the equation of a line?
Answers
Answer:
m is the slope of the line
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
y = mx+b
Where m is the slope of the line and b is the y-intercept. Both parameters define the behavior of the line in terms of it's increasing/decreasing trend, and where it crosses the y-axis.
As an example, let's consider the line
y =3x-8
Here, the slope is 3 and the y-intercept. It means the line is increasing from left to right and the point where it crossed the y-axis is (0,-8).
m is the slope of the line

Answers
This question is solved using binomial distribution concepts:
Doing this, we get that C.) The probability of drawing a card and getting a red or face card is not an example of a binomial distribution.
Binomial distribution:
Each trial, only two possible outcomes.Independent trials, that is, in each trial, same probability of a success.Fixed number of trials.Option a:
Each trial, either a 5 is rolled or not, so yes, two outcomes.Each trial, same probability of not rolling a 5 in each trial, so independent.3 trials, so fixed.Option b:
Each trial, either the player makes the free throw or misses, so yes, two outcomes.Each trial, same probability of a making a free throw, so independent.8 trials, so fixed.Option c:
Each trial, either draws a red or face or not, so yes, two outcomes.Cards are chosen without replacement, which means that for each trial there are different probabilities, so trials are not independent, and this is not a binomial experiment, being the correct option.Option d:
Each trial, either hits the bullseye or not, so yes, two outcomes.Each trial, same probability of hitting the bullseye, so yes, independent.8 trials, so fixed.Thus, option c is the answer.

We have to find out which property justifies Gabrielle's first step.
State the Associative property of Addition.According to associative property of addition changing the grouping of addends does not change the sum.
For example - ( 2 + 3 ) + 4 = 2 + ( 3 + 4 )
According to the question, on the left hand side, we have -
[tex]x^{2} +(6x^{2} +5)[/tex]
Using the associative property of Addition, we can write the above expression as -

5. Kwami had two large sheets of paper. He cut each piece of paper in half, then he cut the smaller pieces of paper in half two more times.
a). Write this as a power.
b). How many pieces of paper does Kwami have now?
Answers
Answer:
a. 2³ b. 8
Step-by-step explanation:
(2*2)=2 papers cut in half
2*2*2=2 papers cut in half twice
2*2*2=2³
2³=8
The situation is 1 x 2 + (1 x 2) ³ = X. Kwami has 10 pieces of paper now.
Since Kwami had two large sheets of paper, and he cut each piece of paper in half, and then he cut the smaller pieces of paper in half two more times, to write this as a power and determine how many pieces of paper does Kwami have now the following calculation must be performed:
First, you must consider the division of the paper, and then consider the number of times that process was repeated.
1 x 2 + (1 x 2) ³ = X 2 + 2³ = X 2 + 8 = X 10 = X
So now Kwami has 10 pieces of paper.

Use Gauss’s approach to find the following sums (do not use formulas).
A. 1+2+3+4+...+998
B. 1+3+5+7+...+101
A. The sum of the sequence is?
B. The sum of the sequence is?
Answers
[A] is the sum of the first 998 consecutive positive integers, so it has 998 terms in it.
Gauss's method involved doubling the sum while grouping terms in a clever way: let S be the sum, so that
S = 1 + 2 + 3 + ... + 996 + 997 + 998
It's also true that
S = 998 + 997 + 996 + ... + 3 + 2 + 1
so that adding these equations together gives
2S = (1 + 998) + (2 + 997) + ... + (997 + 2) + (998 + 1)
2S = 999 + 999 + ... + 999 + 999
We know there are 998 terms on the right side, so
2S = 998 * 999 = 997,002
S = 997,002/2 = 498,501
[B] You can do this one the same way. The hardest part is counting how many terms there are in the sum.
Starting with 1, the n-th positive odd integer is given by 2n - 1. The last term in this sum is 101, so
2n - 1 = 101
2n = 102
n = 102/2 = 51
and the sum contains 51 terms.
Let S denote the sum. Then
S = 1 + 3 + 5 + ... + 97 + 99 + 101
S = 101 + 99 + 97 + ... + 5 + 3 + 1
2S = (1 + 101) + (3 + 99) + ... + (99 + 3) + (101 + 1)
2S = 102 + 102 + ... + 102 + 102
2S = 51 * 102 = 5202
S = 5202/2 = 2601
