Answer:
[tex]-5c[/tex]
Step-by-step explanation:
To find: The sum of [tex]6c-5c[/tex] and opposite of [tex]6c[/tex]
Opposite of [tex]6c[/tex] means taking the opposite sign.
[tex]6c[/tex] is positive. So, opposite sign is [tex]-6c[/tex].
Therefore, the addition is given as:
[tex]=6c-5c+(-6c)[/tex]
Opening the parenthesis, we get:
[tex]6c-5c-6c[/tex]
Now, as per PEDMAS rule, we subtract [tex]6c\ and\ 5c[/tex], we get
[tex]6c-5c=(6-5)c=1c[/tex]
Now, we are left with [tex]1c-6c[/tex]
Subtracting a bigger number from a smaller number will give a negative answer.
So, [tex]1c-6c=(1-6)c=-5c[/tex]
Therefore, the final answer is [tex]-5c[/tex]

Whether you write 'a' as a fraction or 'b' as a decimal in the expression ax+bx depends on the context of the problem you're solving. 'a' can be converted to a fraction by expressing the decimal in fractional terms, whereas 'b' can be turned into a decimal by dividing the numerator by the denominator.
Explanation:In the expression ax+bx, where 'a' is a decimal and 'b' is a fraction, deciding whether to write 'a' as a fraction or 'b' as a decimal depends largely on the problem you're solving and what format is most convenient or understandable. To convert 'a' from a decimal to a fraction, you can write the decimal in fractional form. If the denominator is not 100, convert it to a fraction with a denominator of 100, which then allows you to present it as a percentage. On the other hand, to convert 'b' from a fraction to a decimal, you can simply divide the numerator of the fraction by the denominator.
A practical example could be if a=0.5 and b=3/4 in the expression. Here, you can write 'a' as 1/2 (a fraction) and 'b' as 0.75 (a decimal). Therefore, the expression becomes 1/2x + 0.75x.

The correct answer is provided by the third system.
To determine which system of linear inequalities includes the point (2, 1), we need to substitute this point into each inequality and check if the inequalities hold true. Let's evaluate each system step-by-step:
System 1
y < -x + 3y [tex]\leq[/tex] 0.5x + 3Evaluating at (2, 1):
1 < -2 + 3 → 1 < 1 (False)1 ≤ 0.5(2) + 3 → 1 ≤ 4 (True)The point (2, 1) does not satisfy the first inequality, so it is not in the solution set for the first system.
System 2
y < -0.5x + 3y < 0.5xEvaluating at (2, 1):
[tex]1 < -0.5(2) + 3 \rightarrow 1 < 2[/tex] (True)[tex]1 < 0.5(2) →\rightarrow 1 < 1[/tex] (False)The point (2, 1) does not satisfy the second inequality, so it is not in the solution set for this system either.
System 3
y [tex]\leq[/tex] -x + 3y [tex]\leq[/tex] 0.5x + 2Evaluating at (2, 1):
[tex]1 \leq -2 + 3 \rightarrow 1 \leq 1[/tex] (True)[tex]1 \leq 0.5(2) + 2 \rightarrow 1 \leq 3[/tex] (True)The point (2, 1) satisfies both inequalities, so it is in the solution set for the third system.
System 4
y < 0.5xy [tex]\leq[/tex] -0.5x + 2Evaluating at (2, 1):
[tex]1 < 0.5(2) \rightarrow 1 < 1[/tex](False)[tex]1 \leq -0.5(2) + 2 \rightarrow 1 \leq 1[/tex] (True)The point (2, 1) does not satisfy the first inequality, so it is not in the solution set for the fourth system.
The system of linear inequalities that includes the point (2, 1) is the third one: y [tex]\leq[/tex] -x + 3, and y [tex]\leq[/tex] 0.5x + 2.

Jaime drove from all groceries food store to get rich savings bank and then to AAA hardware. How far did Jaime drive?
Answer:
Jaime drove for 6.127 miles.
Step-by-step explanation:
See the attached diagram.
The length from All Groceries Food store to Get Rich Savings bank along Flower street is x miles (say) and the length from Get Rich Savings bank to AAA hardware along the Broad street is 4 miles.
Since, the Flower street and Broad street are perpendicular to each other, hence,
[tex]\tan 28 = \frac{x}{4}[/tex]
⇒ x = 4 tan 28 = 2.127 miles.
Therefore, Jaime drove for (4 + 2.127) = 6.127 miles ≈ 6.1 miles. (Answer)

Answer:
Part 1: 100
Part 2: 29.19 (Rounded)
Part 3: 20.96 (Rounded)
Step-by-step explanation:
Part 1: Triangle Sum Theorem (All angles of a triangle add up to 180 degrees)
45 + 35 + A = 180
80 + A = 180
Move the constant to the other side
80 + A = 180
-80 -80
A = 80°
Part 2: Law of sines
[tex]\frac{a}{sin(100)} = \frac{17}{sin(35)}[/tex]
Cross multiplication
sin(35)a = 16.7417318
Divide both sides by sin(35)
a = 29.18831866
Part 3: Law of cosines
[tex]b=29.19^{2}+17^{2}-2*29.19*17*cos(45)[/tex] = 439.2809039
Square root the answer
[tex]\sqrt{439.2809039}[/tex] =20.95902917
The value of angle A is 100 degrees and the measure of side a is 29.2 and b is 20.96.
What is a Triangle?A triangle is a polygon with three sides, angles, and vertices.
The triangle ABC, has AB = 17, angle ABC = 45 degree, angle ACB = 35 degree.
The measure of angle A can be determined by using the angle sum property.
45 + 35 + A = 180
80 + A = 180
A = 180-80
A = 100 degree.
Using the law of sines to find the length of side a,
a/ sin A = b/ sin B = c/sin C
a/ sin100 = 17/ sin 35
a = 17 * sin 100 / sin35
a = 29.2
Use the law of cosines to find the length of side b.
b² = c² +a² -2ac cos B
b² = (17)² + (29.2)² - 2* 17* 29.2 cos 45
b² = 439.23
b = 20.96
