Answer:
x = 30
Step-by-step explanation:
Given the expression
-2/3 x - 1 =19
We are to find the value of x
Add 1 to both sides
2/3 x -1 +1 = 19+1
2/3 x =20
Multiply
2/3x × 3 = 20×3
2x = 60
x = 60/2
x = 30.
Hence the value of x is 30

Answers:
Person A receives at least 800 dollars, but no more than 1600 dollarsPerson B receives at least 1000 dollars, but no more than 2000 dollars=============================================================
Explanation:
We don't have enough information to nail down exact figures, but we can make a range estimate.
The two people (call them A and B) share the profits in the ratio of 4 to 5
In shorthand notation, we can say the ratio is 4:5
This means person A gets 4x dollars while person B gets 5x dollars
The ratio 4x : 5x reduces to 4:5 after dividing both parts by x. The variable x is some positive real number.
The total profit is therefore 4x+5x = 9x dollars
This expression 9x is between 1800 and 3600 dollars, including both endpoints
We then can say...
[tex]1800 \le 9x \le 3600\\\\\frac{1800}{9} \le \frac{9x}{9} \le \frac{3600}{9}\\\\200 \le x \le 400[/tex]
We see that x = 200 is the smallest possible x value. This leads to person A and B receiving 4x = 4*200 = 800 dollars and 5x = 5*200 = 1000 dollars respectively. Note how the ratio 800:1000 reduces to 4:5 after we divide both parts by 200. We can see that 800+1000 = 1800 which is the lowest profit possible.
The inequality above shows that x = 400 is the largest x value possible. If this is the case, then person A receives 4x = 4*400 = 1600 dollars while person B receives 5x = 5*400 = 2000 dollars. The ratio 1600:2000 reduces to 4:5 after we divide both parts by 400. We can see that 1600+2000 = 3600 is the largest profit possible.
-------------------------
To summarize:
Person A can receive anywhere between 800 dollars and 1600 dollars (inclusive of both endpoints).Person B can receive anywhere between 1000 dollars and 2000 dollars (inclusive of both endpoints).The actual amount they receive will depend on what the actual profit is. Since we're only given the range of the profit, we can only make an estimated guess of the range for each partner.
-------------------------
Side note: For either person, the ratio of the max to min is 2:1. This tells us that the max amount they receive is double compared to the min amount they receive. It's no coincidence that 3600 is double that of 1800.
Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13 (pi)
5 (pi)
6.5 (pi)
Step-by-step explanation:
step 1. if r = 2, then its area = (pi)r^2 = (pi)(4) = 4pi
step 2. if r = 3 then its area = (pi)r^2 = (pi)(9) = 9pi
step 3. so A is the area of a circle half the sum of our circles with r = 2 and r = 3.
step 4. A = (4pi + 9pi)/2 = 13pi/2 =6.5(pi).

A hybrid SUV can travel 400 miles on a 15-gallon tank of gas. How many miles can it travel on 6 gallons of gas?
Answer:
160miles
Step-by-step explanation:
400miles uses15g what about 6g.
Using cross multiplication. Multiply 6x400/15 = 160miles
Answer:
160 miles
Step-by-step explanation:
If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons
400 miles -> 15 gallons
x miles -> 6 gallons
15 * x = 6 * 400
15x = 2400
x = 2400 / 15
x = 160 miles
The graph shows the number of cups of coffee Sherwin consumed in one day and the number of hours he slept that same night:
A scatter plot is shown. Data points are located at 1 and 9, 3 and 5, 5 and 6, 4 and 4, 2 and 7, and 6 and 4. A line of best fit crosses the y-axis at 10 and passes through the point 6 and 4.
How many hours will Sherwin most likely sleep if he consumes 9 cups of coffee?

Write an equation in slope-intercept form that represents the situation:
Bill started with 15 pairs of shoes. On average, Bill buys 7 new pairs of shoes every 2 months.
Answer:
y = 3.5x + 15Step-by-step explanation:
Number of months is x, and number of pairs of shoes after each month is y.
7 new pairs of shoes every 2 months means that after each month:
y = 7/2 x
We need to add the 15 pairs from start.
y = 3.5x + 15

helppppppppppppppppppppp c/2+5=1
Answer:
c/2=-4
c=-8
Step-by-step explanation:
Answer:
c = -8
Step-by-step explanation:
Okay, so this is a standard equation, so we have to do the thingy thing on each side:
c/2 + 5 - 5 = 1 - 5
c/2 = -4
c/2 x 2 = -4 x 2
c = -8
So, c = -8
13. L'Shonda purchased a container of juice that contains 200 calories. The label says that 40% of the calories are from carbohydrates. How many calories are from carbohydrates?
Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.

Round to the nearest thousand. 6,159
Answer:
6,000
Step-by-step explanation:
To round to the nearest thousand, you keep the digit in the thousands and round up or down, clearing all other smaller units. You round up when the next largest digit, in this case, the hundreds, is 5 or larger. Meanwhile, you round down when it is 4 or smaller. Here it is 1, so you round down to 6,000. If it was 5 or larger, you would round up to 7,000.
6,000
To round a number we look at the number that is right of the one we are rounding. If the number to the left is 4 or under, you round down. If it's 5 or above, you round up.
Hope it helps! Good luck!! :D

Explain the prices of dividing two fractions
Answer:
When dividing two fractions, the process is very easy. You simply multiply the numerator fraction by the reciprocal of the denominator fraction. In other words:

If rectangle LMNO were rotated 180° clockwise about the origin to create rectangle L'M'N'O', what would the measure of angle O' be?
9514 1404 393
Answer:
90°
Step-by-step explanation:
Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.
_____
Additional comment
No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.

Express in the form 1:n
3:12
Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4

In the figure, BC is a support for the roof
of a garage. What is the length of BC?
Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft
