3(2x-4)=3X-3. What is the x?
Answers
Answer:
x = 3
Step-by-step explanation:
Distributive property: a(b + c) = (a*b) + (a*c)
3(2x - 4) = 3x - 3
3*2x - 3*4 = 3x - 3
6x - 12 = 3x - 3 {Add 12 to both sides}
6x -12 + 12 = 3x -3 + 12
6x = 3x + 9 {subtract 3x from both side}
6x - 3x = 3x - 3x + 9
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3
The height of a football after it's been kicked from the top of a hill is h=2(-2-4t)(2t-5) where h is height and t is time in seconds how long was football in the air?
Answers
Answer:
2.5 seconds.
Step-by-step explanation:
When the football reaches the ground h = 0, so:
2(-2 - 4t)(2t - 5) = 0
so either -2 - 4t = 0 or 2t - 5 = 0
so -4t = 2 or 2t = 5
t = -1/2 , t = 5/2 = 2.5 seconds.
WE ignore the negative t , so
Time that the ball was in the air = 2.5 seconds.

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

it's the radius of the circle
it is the circumference of the circle
it is a cord
it is 6cm long
it is diameter of the circle
it is 7cm long
it is 1.75cm long
Answers
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
what is the volume.

Kade has $45 in savings and wants to purchase a video game console for $250. He has a coupon for 10% off, and sales tax is 8.25%. In order to be financially responsible, Kade wants to wait until he has enough in savings to not have to borrow money. If Kade is able to save $45 each week, what is the minimum number of weeks Kade should save before making his purchase?
Answers
Answer:
5 weeks
Step-by-step explanation:
First, solve for the total cost of the game console after tax and a coupon
Solve for tax:
$250 × 8.25%
Convert percentage into a decimal
250 × 0.0825
20.625
Round up to nearest hundredths place (because the unit is dollars)
20.63
Add this tax onto the original cost
250 + 20.63
270.63
Subtract the coupon from the total
270.63 - 10
260.63
Total cost is $260.63
Now let's find how much Kade needs to save so set up an equation
Variable x = number of weeks
45 + 45x = 260.63
Subtract 45 from both sides to isolate the variable
45x = 215.63
Divide both sides by 45
x = 4.791777...
Round up to nearest whole number (because units are weeks)
x = 5 weeks

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answers
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45
