x+3 is the answer to this problem.
Step-by-step explanation:
If x > 5, then x + 3 is positive, so we can simplify the absolute value expression |x + 3| by removing the absolute value brackets and keeping the expression inside them:
|x + 3| = x + 3
Therefore, if x > 5, the simplified form of |x + 3| is just x + 3.

Step-by-step explanation:
-25x+175>225 AND 5x-83 >= -73
In order to solve for the first inequality you would need to combine like terms:
-25x > 225-175
= -25x > 50
Next you would divide by -25 however, wheneve dividing by a negative number you would switch the sign:
x < -2
Now for the next inequality you would combine like terms:
5x >= -73+83
= 5x >= 10
Now divide by 5 on each side:
x >= 2
In this scenario the inequality says AND
However, x can't be greater then two and less then -2 since 2 is greater then negative two. Therefore, the answer is NO SOLUTION

Answers
Step-by-step explanation:
The area of a rhombus is given by the formula A = (1/2)bh, where b is the length of the base and h is the height.
In this case, the base is 20 centimeters and the height is 18.9 centimeters. So, the area of the rhombus is:
A = (1/2)(20)(18.9) = 189 square centimeters
Therefore, the answer is option B: 189 cm2.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.
Answers
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300

After 1 year, $50,000 deposited in a savings account with simple interest had earned $2,500 in interest. What was the interest rate?
pls explain how as well if you don't mind
Answers
Answer:
5%
Step-by-step explanation:
The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Interest is the amount of money earned as interest
Principal is the initial amount of money deposited
Rate is the interest rate (expressed as a decimal)
Time is the duration for which the money is invested or the time period over which interest is calculated
In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.
We can rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Plugging in the given values:
Rate = $2,500 / ($50,000 × 1)
The calculation simplifies to:
Rate = $2,500 / $50,000
Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:
Rate = 0.05
To express the interest rate as a percentage, we multiply the decimal value by 100:
Rate = 0.05 × 100
Rate = 5%
Therefore, the interest rate for the savings account is 5%.
Answer:
Interest Rate = 5%
Step-by-step explanation:
Principal = $50, 000
Rate = ?
Time = 1 yr
S.I = PRT/100
2,500/1 = 50,000 × R × 1/100
50,000R = 2,500 × 100
50,000R = 250,000
50,000R/50,000 = 250,000/50,000
R = 5 %

The second choice ([tex]x + y[/tex])
Step-by-step explanation:
If x = [tex]-\frac{5}{6}[/tex] and y = [tex]\frac{4}{3}[/tex], then we can insert those in for [tex]x[/tex] × [tex]y[/tex].
[tex]-\frac{5}{6}[/tex] × [tex]\frac{4}{3}[/tex] = ?To determine if this will have a positive outcome, we don't even need to solve! We know that a negative multiplied by a positive will result in a negative product.
Therefore, this is not the correct answer.
Looking at the second choice, [tex]x + y[/tex] we can insert our numbers in for [tex]x[/tex] and [tex]y[/tex]:
[tex]-\frac{5}{6} + \frac{4}{3} = \frac{1}{2}[/tex]The outcome of the two is a positive, marking it the correct answer.
Even though we already know the answer, we can still check the other choices to be sure.
[tex]\frac{x}{y} = \frac{-\frac{5}{6} }{\frac{4}{3} } = -\frac{5}{8}[/tex]The outcome of this is a negative, meaning it is incorrect.
For the last choice, we can once again insert the fractions in for [tex]x[/tex] and [tex]y[/tex]:
[tex]-\frac{5}{6} - \frac{4}{3} =-\frac{13}{6}[/tex]
This product is once again a negative, meaning it is incorrect.
Therefore, the second choice is the correct answer.

96 - x = 64
ninety minus ? equals sixty four
Answers
Hello!
96 - x = 64
96 - x + x = 64 + x
96 = 64 + x
96 - 64 = 64 + x - 64
x = 32
ninety six minus ? equals sixty four
? = 96 - 64 = 32
Answer: x = 32
Step-by-step explanation: By using inverse operations, you may separate the variable x from the other variables in equation 96 - x = 64. Let's tackle it piece by piece:
Let's begin with the formula 96 - x = 64.
We must get rid of the 96 on the left side of the equation in order to focus on the variable x. 96 can be taken out of both sides of the equation to accomplish this: (96 - x) - 96 = 64 - 96.
To put it simply, -x = -32.
We want to remove the minus sign from the front of x so that we can solve for x. By multiplying both sides of the equation by -1, we can do this:
(-1)(-x) = (-1)(-32).
So, if we simplify, we get x = 32.
As a result, x = 32 is the answer to the equation 96 - x = 64.
