Answer:
13
Step-by-step explanation:
Evaluate the expression for v = 2.
First, plug in 2 wherever v is seen.
5v + 3
5(2) + 3
Next, multiply.
5(2) + 3
10 + 3
Add.
10 + 3
13
Your final answer is 13.
Please let me know if there are any issues with this answer.
Answer:
i think this is algebra
Step-by-step explanation:
The first thing you have to do is open the multiplication parenthesis to substitute V for 2
5v + 3
5 (2) + 3
Now that you have the parenthesis, you multiply and then the result that you add.
5(2) or 5x2= 10 but is better with parenthesis.
10 + 3
=3

The inequality that describes the possible value of x is 2< x < 22.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given that ∠A = 50°
AB ≈ DE ≈ EF
BC = 12
CD = 10
And the ∠E = (5x - 10)°
From the Graph, we can see that Angle A is the alternate angle to angle G
Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.
thus, ∠A = ∠E
50° = 5x -10
5x = 60
x = 12
Therefore, from the given options the value of x lies in the inequality 2 < x < 22.

On a bicycle, Caitlyn rides for 4 hours and is 46 miles from her house. After riding for 7 hours, she is 79 miles away. What is her rate?
Answer:
Caitlyn's average is roughly 11.4.
Step-by-step explanation:
You get this by dividing 46 by 4, which gets you 11.5.
You then divide 79 by 7, that equals 11.3, rounded.
The number in-between the two numbers is 11.4.

Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰

Answer:
Texas is 2.08333 * 10^2 times the size of Carolina.
Step-by-step explanation:
Given :
Given that:
Texas= 2.5x10^5
Carolina = 1.2x10^3
Comparing the size of Texas and Carolina
Texas / Carolina
(2.5 * 10^5) ÷ 1.2 * 10^3
(2.5/1.2) * 10^5-3
2.08333 * 10^2
Hence, Texas is 2.08333 * 10^2 times the size of Carolina.

i well try to give brainlist for first to answer correctly
Answer:
The price increased by 64.5, which makes a total of 279.5
Step-by-step explanation:
215*0.30 = 64.5
215 + 64.5 = 279.5
0.30 = 30% of 100
When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

A few friends went bowling. The scores
are given below. Use the scores to
calculate the range of the data. *
(1 Point)
104, 117, 104, 136, 189, 109, 113, 104
Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85

If he plays the game 12 times, about how many times can he expect to win?
Answer:50%
Step-by-step explanation:
Steve's expected times of winning in 12 trials is about 2 times.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
The winning chance of Steve is 20% or 0.2.
We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.
Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.
Therefore, If he plays the game 12 times the number of times he is expected to win is,
= 12×0.2.
= 2.4 Or 2 times.

Mohamed wants to buy a television that costs $800, including taxes. To pay for the television, he will use a payment plan that requires him to make a down payment of $200, and then pay $65 each month for 10 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
6.25%
Step-by-step explanation:
I'm simply returning the favor.
If the down payment is $200, then we can subtract:
$800 - $200 = $600
Then we can find the "rent" times ten, then subtract it from the $600 left to pay.
$65*10 = $650
Now here is the hard part. We know that 600 < 650. So we need to subtract 650 from 600.
$650 - $600 = $50
Now we need to find how much more Mohamed paid than the original price.
$850 is _____% more than $800.
$850 is 106.25% more than $800.
Subtract 100% to get the difference.
6.25% is your answer.
Hope this helps. Have a nice day.
