[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]
Answer:
C.) x = 3
Step-by-step explanation:
The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.

Jaulas father throws Kayla a graduation party that costs $773. He pays the DJ $250, $75 for the cake, and $4 per party guest for food. How many guests were at the party?
Answers
Answer:
112 guests
Step-by-step explanation:
I. If her total cost is 773$
When Total = DJ + Cake + Guest
773 = 250 + 75 + 4(x)
773 = 325 + 4(x)
773 - 325 = 4(x)
448 = 4x
x = 448/4
x = 112
That makes guests are 112

Answer:
x = 125
Step-by-step explanation:

x = 180 - 55
x = 125
ROCKET SLED On a track at an Air Force base in New Mexico, a rocket sled
travels 3 miles in 6 seconds. What is the average speed in miles per hour?
Answers
Answer:
Answer: Rocket distance (rocket sled) =3 mil Time Taken=6seconds
Average Speed=Total Distance ÷ Time Taken. Average speed= 3÷ 6=1/2. So therefore average speed in miles per seconds= Average in miles/seconds
Average speed in miles per seconds=1/2
Average in miles/hour = Average speed in miles per seconds/hour.
Average in miles/hour=1/2÷60=30
Therefore Average speed in miles per hour =30 miles per hour

Answers
Answer:
B) [tex]x\geq0[/tex]
Step-by-step explanation:
The domain of the square root function is all real non-negative numbers. In a numerical format that is as follows:
[tex]D(\sqrt{x})={[0,\infty )}[/tex]
This is more commonly denoted as:
[tex]x\geq0[/tex]
In the case of the given function:
[tex]g(x)=\sqrt{8x}[/tex]
The domain is still ([tex]x\geq0[/tex]) as multiplying a value by (8) does not alter this. A negative number times (8) is still negative and thus cannot be a part of the square root domain. Similarly, a positive number times (8) is still positive and remains a part of the square root domain. Moreover, (0) times (8) is still (0).

Berny bought a soft drink for 2 dollars
and 6 candy bars. He spent a total of
20 dollars. How much did each candy bar cost
bar cost?
Answers
Answer:
3
Step-by-step explanation:
Given:
Berny spent 20 dollars total
He spent 2 dollars on a soft drink
He bought 6 candy bars
Solution:
Amount spent on candy bars = total amount spent - amount spent on soft drink.
Amount spent on candy bars = 20 - 2 = 18
Cost of each candy bar = total amount spent on candy bars / # of candy bars bought
Cost of each candy bar = 18/6 = 3
Answer: Each candy bar costs $3
Step-by-step explanation:
Set variables
Soft drink = $2
Candy bars = $6x
Let x be the cost for each candy bar.Total cost = $20
Set equation
2 + 6x = 20
Subtract 2 on both sides
2 + 6x - 2 = 20 - 2
6x = 18
Divide 6 on both sides
6x / 6 = 18 / 6
x = 3

1. When adding two integers, what will the sign of the sum be if: c. one integer is positive and one integer is negative?
Answers
Answer:
Step-by-step explanation:
The largest absolute value gets the sign.
To use an example
4 - 8
Think money for a moment. You have 4 dollars in your pocket. You owe your mother 8 dollars. Where are you?
You should think you are 4 dollars in debt. That being the case, the sign of the answer is minus.
4 - 8 = -4 Eight is the largest number if its absolute value is taken. Absolute value means you turn it positive and subtract.
Suppose the question is
-9 + 5 Again money. You have 5 dollars in your pocket, but this time you owe mom 9 dollars
She wants her -4 dollars right now.
