The sum of two integers is -27. If one of them is 260. find the other.

I NEED THIS ASAP!!!
PLSSSSSSSSS

Answers

Answer:

-287

Step-by-step explanation:

If x + y = z, then z - y = x and z - x = y. Since 260 + x = -27, then -27 - 260 = x.

You can change the signs for a moment but you need to change them back at the end. 27 + 260 = 287, flip the signs, -27 - 260 = -287.

Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?

Answers

Answer: The cost of each baseball cap = $15.

Step-by-step explanation:

Let x = cost of each baseball cap

Given; cost of each baseball jersey= $45

Total coast of 3 baseball caps and 1 baseball jersey = $90

i.e. [tex]3x+45=90[/tex]

[tex]\Rightarrow\ 3x=45\\\\\Rightarrow\ x=\dfrac{45}{3}\\\\\Rightarrow\ x= 15[/tex]

Hence, the cost of each baseball cap = $15.

you plug the number for the variable into the equation (3(2)²+6order of operations say exponents first so you do 2²=4 so you have 3(4)+6then you multiple 3•4=12 so 12+6finally you add 12+6=18

plug in the number for the variable so 5–(-5)so a negative and a minus will make it addition (negative + negative = positive)do it is 5+5 which equals 10

If CE bisects ZBCD and if m ZBCE = 3x - 6
and mZECD = 2x + 11, find mZBCD. Is
ZBCD acute, right, or obtuse?

Answers

Answer:

m∠BCD = 90°

∠BCD is a right angle

Step-by-step explanation:

If a ray bisects an angle, that means it divides the angle into two equal parts in measure

Ray CE bisects ∠BCD

→ Means divide it into two angles BCE and ECD which equal in measures

m∠BCE = m∠ECD = [tex]\frac{1}{2}[/tex] m∠BCD

∵ m∠BCE = 3x - 6

∵ m∠ECD = 2x + 11

→ Equate them to find x

3x - 6 = 2x + 11

→ Add 6 to both sides

∵ 3x - 6 + 6 = 2x + 11 + 6

∴ 3x = 2x + 17

→ Subtract 2x from both sides

∵ 3x - 2x = 2x - 2x + 17

x = 17

∵ m∠BCE =  [tex]\frac{1}{2}[/tex] m∠BCD

→ Substitute x in the measure of ∠BCE to find it, then use it to

   find m∠BCD

∵ m∠BCE = 3(17) - 6 = 51 - 6

∴  m∠BCE = 45°

45 = [tex]\frac{1}{2}[/tex] m∠BCD

→ Multiply both sides by 2

∴ 90 = m∠BCD

m∠BCD = 90°

→ The measure of the acute angle is less than 90°, the measure of

   the obtuse angle is greater than 90°, and the measure of the

   right angle is 90°

∠BCD is a right angle

Maya is taking her friends to a concert. Each ticket costs
$25, and souvenir T-shirts are $12 each. There is a $4
service fee for the entire purchase. She has $130. If she
buys 3 tickets, what is the maximum number of T-shirts
she can buy?
If x = number of tickets and y= number of T-shirts, which of the following
inequalities could you use to answer the problem?

Answers

Answer:

C. 25x+12y+4≤ 130

Step-by-step explanation:

Each ticket cost $25, so x would be the number of tickets she has to buy.

25x

Each T-shirt cost $12, so y would be the number of T-shirts she can buy.

12y

And since there is an service fee for the entree purchase, that's another $4.

+4

The cost of everything has to be less than $130, so the equation would be:

25x+12y+4≤ 130

The number of years that Zach has been on the soccer team is 2 less than 5
times the number of years that Anderson has. In total, the boys have been on
the soccer team for 10 years. How long has each boy been on the soccer team?

Answers

Answer:

Brad has been on the team for 8 years. Apply that and that means that Anderson has been on the soccer team for 2 years.

Step-by-step explanation:

I dont know how to explain lol i made an equation and figured it out

Step-by-step explanation:

let x be the number of years that Zach has been on the soccer team and y the number of years Anderson has been on the soccer team.

So, reading our problem it seems that

x=5y-2

x+y=10

replacing x on the second formula we take that 5y-2+y=10

6y-2=10

6y=12

y=2

so x=5y-2=5*2-2=10-2=8

Suppose a friend tells you she paid a total of $19,875 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in : Lilburn with a percentage of 7%

Answers

Answer:

10.31%

Explanation:

This is the answer

friend bought the car in  Lilburn with a percentage of 7% ie the price list of the car is  $18483.75.

How do I calculate percentage?If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.The proportion therefore refers to a component per hundred.Per 100 is what the word percent means.The letter "%" stands for it.Percentage, which meaning "per 100," designates a portion of a total sum.The use of percentages is widespread and diverse.For instance, many statistics in the media, bank interest rates, retail discounts, and inflation rates are all expressed as percentages.For comprehending the financial aspects of daily life, percentages are crucial.

The friend paid total of $19,875 for a car.

7% of  19,875 = 1391.25.

The list price of the car = 19,875 -  1391.25 = 18483.75

Which of the following rules describes the function graphed below? On a coordinate plane, points are at (1, 5), (2, 4), (3, 3), (4, 2). a. Output = Input c. Output = 5 · Input - 4 b. Output = Input - 4 d. Output = 6 - Input Please select the best answer from the choices provided A B C D

Answers

*see attachment

Answer:

D. Output = 6 - Input

Step-by-step explanation:

The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.

Let's consider the function and see which rule best describes the function.

Considering the point (1, 5), the rule, output = 6 - input, applies.

Let's check it out:

Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:

Output = 6 - 1

Output = 5

If you try another coordinate pair of the function, the same rule will apply.

Therefore, the best answer is D. Output = 6 - Input
