divide the sum of 7/9 and 2/3 by 5/3
Answer:13/15
Step-by-step explanation:
Add 7/9 and 2/3 the answer is 13/9 then divide it by 5/3 in order for you to divide get the reciprocal of 5/3 which is 3/5 then multiply it and you well get 13/15
Answer:
13/15
Step-by-step explanation:
The answer is 13/15 because:
1) In order to figure out what 7/9 + 2/3 is, we need to find the common denominator. The common denominator is 9 because 3 contains the factor 9.
7/9 + 6/9 = 13/9
We need to multiply the denominator to get to 9: 3 x 3 = 9. We have to multiply the numerator as well: 2 x 3 = 6.
2) Next, we have to divide 13/9 and 5/3. In order to divide we have to find the reciprocal of the second number. Reciprocal means to flip the fraction. The reciprocal of 5/3 is 3/5.
3) Finally, we just have to multiply 13/9 and 3/5 which is 39/45. 39/45 in simplest form is 13/15.
Hope this helps! :D

The function f(x) is defined below. What is the end behavior of f(x)?
Please help!!
you're answer would be number 3
Please help I will give brainliest.
Answer:
yes
yes
no
no
yes
Step-by-step explanation:
f(x) = y = x² + 2x = x(x + 2)
the y-intercept (the point with the y value where x = 0) is
y = 0² + 2×0 = 0
yes, the y-intercept is (0, 0).
yes, the graph opens upward, as x² is the most powerful and therefore driving term in the expression. so, it behaves basically like x².
no, the x-intercepts are the points, where y = 0.
and while (0, 0) is correct, but (2, 0) is not.
x = 2 gives us 2² + 2×2 = 4 + 4 = 8 as y value.
the second correct x-intercept would be (-2, 0).
x = -2 gives us (-2)² + 2×-2 = 4 - 4 = 0
no (see last point)
yes, the vertex is (-1, -1).
we get the extreme value (in this case the minimum, as the curve opens upward) by finding the zero of the first derivative :
f'(x) = 2x + 2 = 0
2x = -2
x = -1
y = (-1)² + 2×-1 = 1 - 2 = -1

Calculate the area of the floor:
Area = 1.6 x 2.3 = 3.68 square meters
Using the given formula: Pressure = force/area
200 = force / 3.68
Solve for force by multiplying both sides by 3.68
Force = 200 x 3.68
Force = 736 N/m^2
Correct to the nearest 5N/m^2 = 735 N/m^2
First of all we need to calculate the area of the floor and then we will find the pressure using the formula for pressure...

Two months ago, the mean daily rainfall in a local city was 9. 4 cm. The mean absolute deviation was 3. 5 cm. Last month, the mean daily rainfall in that city was 11. 5 cm, and the mean absolute deviation was 1. 6 cm. Which statement about the rainfall is true? More rain fell two months ago than last month. About the same amount of rain fell two months ago as last month. Last month, the amount of rain that fell each day varied about the same as the month before. Last month, the amount of rain that fell each day varied less than the month before.
Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.
What is the mean absolute deviation?The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset is.

Answer: x = 5
Step-by-step explanation:
(3x + 22) and (3x + 128) are supplementary angles, which means that they add up to 180, so we can write our equation.
(3x + 22) + (3x + 128) = 180
3x + 22 + 3x + 128 = 180
6x + 150 = 180

la suma entre el triple de un numero y el doble de su consecutivo es 37 ¿cuál es el número?

Step-by-step explanation:
What value of x is in the solution set of 9(2x + 1) < 9x - 18?
04
0 -3
0 -2
0-1
Let's solve for x
9(2x+1) < 9x - 18
18x+9 < 9x-18
18x-9x < -18-9
9x < -27
x < -27/9
x < -3
Any value smaller than -3 is in the solution set
That means we have {-4, -5, -6, ...} as our solution set if x was only allowed to be an integer.
We can rule out choices B through D because of this. Only choice A remains, which I'm assuming you meant to say -4 instead of simply 4. If choice A says -4, then this is the answer.
If it doesn't say -4, then that isn't the answer and none of the answer choices work.
Note: if your original inequality is [tex]9(2x+1) \le 9x-18[/tex] then it solves to [tex]x \le -3[/tex] allowing x = -3 to be part of the solution set now. If you have an "or equal to" then that means B) -3 is the answer.
It seems like there might be a typo somewhere so I would double check.
