The solution of the given equation is 1.6. It has been represented and solved as a real-world problem below.
The given equation is = - 20 + 2x5 = 4
We can rewrite this equation as = - 4 + 2x5 = 20
Let us suppose that person A has x number of bananas that they have taken out from a stock full of bananas. They continue taking x number of bananas two more times. They then stop and see that person B has already taken 4 bananas from the stock. We can write this equation as -
= 4 + 2x
Person A saw knew that there were 20 bananas in total. So, we can write it as -
= 4 + 2x = 20
Person A then resumed and took x number of bananas again 5 more times. We can rewrite this as -
= 4 + 2x5 = 20
Solving this equation, we get -
= 4 + 10x = 20
= 10x = 20-4 = 16
= x = 16/10
= x = 1.6

The total number of clients with a BMI of 25.9 or higher is therefore equal to 1 * 2.6 + 3 * 2
The total amount of money she would need to give in discounts next month can be found by calculating the total number of clients with a BMI of 25.9 or higher. To calculate this, the frequencies of each BMI range need to be multiplied by the width of the corresponding bar. The total amount of money she would need to give in discounts is then equal to the total number of clients with a BMI of 25.9 or higher multiplied by $50.
Using the histogram, the number of clients in each BMI range are: 18.1-20.7 (1), 20.7-23.3 (3), 23.3-25.9 (5), 25.9-28.5 (2), 28.5-31.1 (1).

Solve these equations for x.
-(3x - 12) = 9x -4
Answer:
x= 4/3
Step-by-step explanation:
Think the negative sign outside the parentheses as -1. Then do distributive property to the numbers inside the parentheses.
-1 x 3x and -1 x -12
That equals to -3x + 12 so now your entire equation is -3x + 12 = 9x - 4. Now lets take away 9x from both sides like this,
9x - 9x and -3x - 9x.
That equation is now -12x + 12 = -4.
Now subtract 12 from both sides like this,
12 - 12 and -4 - 12.
And then you have -12x = -16.
Now you divide both numbers by -12 like this,
-12x/-12 which equals to just x and then do -16/-12 which would equal as 1.3333 and repeating but, it can be put as 4/3 for a clearer answer.
So your answer is
x = 4/3

The area of rectangle WXYZ is 115. 5 in. ² what is the perimeter of triangle XYZ

The perimeter of triangle XYZ is 38.95 inches
Consider the following figure.
The area of rectangle WXYZ is 115. 5 in.²
From given figure we can observe that PQ = 4 in.
So, XW = YZ = 2 × PQ
XW = YZ = 2 × 4
XW = YZ = 8 inches
This means, the width of rectangle WXYZ is 8 inches
We know that the area of the reactngle is given by the formula,
A = length × width
here, A = 115.5 in.² and width = 8 in.
115.5 = length × 8
length = 115.5 / 8
length = 14.44 in.
So, XY = WZ = 14.44 in.
For right triangle XYZ using Pythagoras theorem,
XZ² = XY² + YZ²
XZ² = 14.44² + 8²
XZ² = XY² + YZ²
XZ² = 272.51
XZ = 16.51 in.
So, the perimeter of triangle XYZ would be,
P = XY + YZ + XZ
P = 14.44 + 8 + 16.51
P = 38.95 inches

(i.e. p(x = 2) = 0.3). the reward depends on whether the rolled dice shows an even number or an odd number. if you roll an even number you will win 100$ and if you roll an odd number you will lose 200$ (i.e. you win -200$). what is the expected reward amount (the expected value may be negative)?
The expected reward amount is -10$.
Expected Reward Amount
The product of the likelihood of each occurrence and the related reward results in the anticipated reward amount, which is equal to the expected reward value.
According to the question
We must multiply the odds of rolling an even number by the payout for rolling an even number, the odds of rolling an odd number by the payout for rolling an odd number, and then sum the results to determine the expected payoff.
P(odd) = P(1) + P(3) + P(5) = 0.1 + 0.1 + 0.1 = 0.3
P(Even) = P(2) + P(4) + P(6) = 0.3 + 0.2 + 0.2
The expected reward is calculated as follows:
(p(even) * 100 + (p(odd) * 200)) = (0.7 * 100 + (0.3 * 200)) = 70 - 60 = -10
As a result, the predicted reward is -10$.

Three lots with parallel side boundaries extend from the avenue to the boulevard.

According to the proportion theorem,
Solving for x, using cross multiplication:
Similarly,
x/40 = z/35
solving for z by cross multiplication,
z = 35x/40
z = 7x/8
Now, the third proportions,
y/30 = z/35
Solving for y,
y = 30z/35
y = 6z/7
x + y + z = 140
4y/3 + 6z/7 + 7x/8 = 140
(224y + 144z + 147x)/168 = 140
224y + 144z + 147x = 23520
Substituting z = 7x/8,
224y + (144 × 7x/8) + 147x = 23520
224y + 126x + 147x = 23520
224y + 273x = 23520
Now,
Substitute y = 3x/4
(224×3x/4) + 273x = 23520
168x + 273x = 23520
441x = 23520

The hypotenuse of the right triangle, which also contains the cone height as one of its legs, is formed by the radius (18 m) and slant height. You may find out the height (h) using the Pythagorean theorem.
The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.
So,

Noah and Lin are making paper cones to hold popcorn to hand out at a parent math night. They want the cones to hold 9π cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
The two different possible values for height h and radius r for the cones are height = 3 inches when radius = 3 inches and height = 4.5 inches when radius = 2 inches.
The volume of a cone is given by the formula [tex]V = (1/3)\pi r^2 h[/tex].
We can use this formula to find the values of h and r that will give us a cone with a volume of 9π cubic inches.
We have a volume of the cone -
(1/3)π[tex]r^2[/tex]h = 9π
solving for h, we get,
h = (3/[tex]r^2[/tex]) * 9
Now we have a formula for h in terms of r. We can substitute different values for r and see what values of h we get. Let's consider two possibilities:
case 1: r = 3 inches:h = (3/[tex]3^2[/tex]) * 9 = 3 inches
case 2: r = 2 inches:h = (3/[tex]2^2[/tex]) * 9 = 4.5 inches
So, one possible cone has a height of 3 inches and a radius of 3 inches, and another possible cone has a height of 4.5 inches and a radius of 2 inches.
