Answer:
2/3
Step-by-step explanation:
that does not say + it a division sign how to got 2/3
(3/4) / x = (9/8)
To solve this equation, we want x alone so we start by multiplying x on both sides like this:
((3/4) / x)x = (9/8)x
Which equals:
(3/4) = (9/8)x
Then we divide each side by 9/8 to like this:
(3/4) / (9/8) = ((9/8)x) / (9/8)
(3/4) / (9/8) is 2/3 and ((9/8)x) / (9/8) leaves x which means we end up with x = 2/3. Therefore, the answer to "3/4 divided by what equals 9/8?" is as follows:
2/3
It is always good to double-check your math to make sure you did it right. When we entered 2/3 for x in this equation (3/4) / x = (9/8), we get the following true equation which means our math is correct.
(3/4) / (2/3) = (9/8)
The value of x will be 2/3
What is an equation?
Equation: An equation is basically a statement that equates two expressions.
An equation must contain an "equality" sign.
Given,
3/4 + x = 9/8
Let us make it correct . Replace + sign with / to get the required answer.
(3/4) / x = (9/8)
To solve this equation, we want x alone so we start by multiplying x on both sides like this:
((3/4) / x)x = (9/8)x
(3/4) = (9/8)x
Then we divide each side by 9/8 to like this:
(3/4) / (9/8) = ((9/8)x) / (9/8)
(3/4) / (9/8) is 2/3 and ((9/8)x) / (9/8) leaves x which means we end up with x = 2/3.
Therefore, the answer to "3/4 divided by what equals 9/8?" is as follows:2/3

Write an equation of the line in slope-intercept form that is parallel to the line y= -4 + 2 and passes through (2,4)
Answer:
Step-by-step explanation:
If the lines are parallel, it means that the slopes are the same. To write an equation in the slope intercept form, we need the slope and the y-intercept. We are given the slope. We need to find the y-intercept. We can use the slope and the point to help us. The point is written in the form (x,y). In this case the point is (2,4) so we will use 2 for x and 4 for y.
y = mx + b Plug in what we know
4 = -4(2) + b b is what we are looking for. It is the y-intercept
4 = -8 + b Now add 8 to both sides
12 = b
Now we can write the equation:
y = -4x +12

When Jay and Elle work together, the job takes 42 minutes.
How long would each person take working individually?
It takes Jay, Elle and Kay to work individually for 70 minutes, 105 minutes and 52.5 minutes respectively
What is Rate and Ratio ?A ratio can sometimes be regarded as fraction. While rate has something to do with time.
Given that Jay and Kay can pack the shelves in one aisle of the supermarket in 30 minutes. Kay and Elle take 35 minutes to do the same job. When Jay and Elle work together, the job takes 42 minutes.
Let
J = Jay K = KayE = ElleThe interpretation of the question go thus;
1/J + 1/K = 1/30 ........ (1)
1/K + 1/E = 1/35 .........(2)
1/J + 1/E = 1/42 .........(3)
Make 1/J and 1/E the subject of formula in equation 1 and 2 respectively and substitute them in equation 3
1/J = 1/30 - 1/K ........ (4)
1/E = 1/35 - 1/K .........(5)
1/30 - 1/K + 1/35 - 1/K = 1/42
Collect the like terms
- 1/K - 1/K = 1/42 - 1/30 - 1/35
-2/K = (35 - 49 - 42)/1470
-2/K = -56/1470
1/K = 28/1470
Reciprocate both sides
K = 1470/28
K = 52.5 minutes.
Substitute K in both equation 4 and 5
1/J = 1/30 - 28/1470
1/J = (49 - 28)/1470
1/J = 21/1470
Reciprocate both sides
J = 1470/21
J = 70 minutes
1/E = 1/35 - 28/1470
1/E = (42 - 28)/1470
1/E = 14/1470
Reciprocate both sides
E = 1470/14
E = 105 minutes
Therefore, it takes Jay, Elle and Kay to work individually for 70 minutes, 105 minutes and 52.5 minutes respectively

To measure the distance across a lake, a surveyor has taken the measurements shown in the diagram below. Determine the distance across the lake.
Using the law of cosines, it is found that the distance across the lake is of 978.5 feet.
What is the law of cosines?The law of cosines states that we can find the angle C of a triangle as follows:
[tex]c^2 = a^2 + b^2 - 2ab\cos{C}[/tex]
in which:
c is the length of the side opposite to angle C.a and b are the lengths of the other sides.In this problem, the parameters are:
a = 800, b = 900, C = 70º.
Hence the distance across the lake is c, found as follows:
[tex]c^2 = a^2 + b^2 - 2ab\cos{C}[/tex]
c² = 800² + 900² - 2(800)(900)cos(70º)
c² = 957491

a. Determine the total surface area, in m², of the sunshade.
The total surface area, in m², of the sunshade is 0.4344 m²
How to calculate surface area of a squared pyramid ?A pyramid can have a squared base, rectangular base or other polygons. The formula we can to find the total surface area of a squared pyramid is
Surface Area = P x l/2
Where
P = base parameterl = slant heightGiven that a sunshade on one set of equipment has a square base of 120 cm and a height of 50 cm. That means that the length L of the base will be 120 cm and half of it will be 60 cm
To find the slant height l, we will use Pythagoras theorem.
[tex]l^{2}[/tex] = 60² + 50²
[tex]l^{2}[/tex] = 3600 + 2500
[tex]l^{2}[/tex] = 6100
l = √6100
l = 78.1 cm
convert it to meter
l = 78.1/100
l = 0.781 m
The perimeter P of the base = 4 x 120/100 = 4.80 m
The Surface Area = P x l/2
Substitute all the necessary parameters into the formula
Surface Area = 4.80 x 0.781/2
Surface Area = 1.8744 m²
If the sunshades are open-bottomed square based pyramids, this means that the base is not included. That is, the area of the base should be taken away from the answer above.
Area of the base = 120/100 x 120/100 = 1.44 m²
The total surface area, in m², of the sunshade will 1.8744 - 1.44

Step-by-step explanation:
First you need to distribute the three into the numbers in the parenthesis,
(3 * x) + (3 * -5) - (2x + 4)
That then turns into,
3x - 15 - (2x + 4)
but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)
3x - 15 + (-1 * 2x) + (-1 * 4)
that turns into,
3x - 15 - 2x -4
from here all we have to do is add like terms,
(3x - 2x) + (-15 + -4)
and that leaves us with: 1x -19 or x-19
