Answer:
x = 2
Step-by-step explanation:
First, you cross multiply then that will give you
9x - 3 = 5x + 5
collect like terms
9x - 5x = +5 + 3
= 4x = 8
Divide both sides by the coefficient of x that's 4

2. Write an algebraic expression for the total number of minutes in h hours and 20 minutes.
3. Write an algebraic expression for the total number of hours in 2 hours and x minutes.
4. Write an algebraic expression for the total number of hours in y hours and 45 minutes.
Answer:
The expressions are:
2. [tex]60h+20\ minutes[/tex]
3. [tex]2+\frac{x}{60}\ hours[/tex]
4. [tex]y+0.75\ hours[/tex]
Step-by-step explanation:
The given expressions have to be converted into algebraic expressions.
So,
2. Write an algebraic expression for the total number of minutes in h hours and 20 minutes.
Here,
h is a variable that can have any value but the 20 minutes will remain same with any number of hours.
If h is for hour, the number of minutes in h hours will be: [tex]60*h = 60h[/tex]
And there are also 20 minutes so the algebraic expression is:
[tex]60h+20\ minutes[/tex]
3. Write an algebraic expression for the total number of hours in 2 hours and x minutes.
In order to convert minutes into hour, the minutes are divided by 60
So converting x minutes into hour means
[tex]x\ minutes = \frac{x}{60}\ hours[/tex]
There are 2 hours already so the expression will be:
[tex]2+\frac{x}{60}\ hours[/tex]
4. Write an algebraic expression for the total number of hours in y hours and 45 minutes.
Converting 45 minutes to hours by dividing by 60
[tex]45\ minutes = \frac{45}{60}\ hours = 0.75\ hours[/tex]
The expression is:
[tex]y+0.75\ hours[/tex]
Hence,
The expressions are:
2. [tex]60h+20\ minutes[/tex]
3. [tex]2+\frac{x}{60}\ hours[/tex]
4. [tex]y+0.75\ hours[/tex]
10 1/2 cups of flour are needed to make 3 loaves of bread. How many cups are needed for 12?
Answer:
42 cups of flour
Step-by-step explanation:
12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.
All we need to do for this is do 10.5 × 4 = x and solve for x.
10.5 × 4 = 42 cups of flour

What is the angle of depression from the start of a 6-foot high access ramp that ends at a point 40 feet away along the ground? Nearest tenth of a degree.
Given:
Height of access ramp = 6 foot
Ramp ends at a point 40 feet away along the ground.
To find:
The angle of depression in nearest tenth of a degree.
Solution:
Using the given information, draw a figure as shown below.
In a right angle triangle,
[tex]\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]
In triangle ABC,
[tex]\tan \theta=\dfrac{AB}{BC}[/tex]
[tex]\tan \theta=\dfrac{6}{40}[/tex]
[tex]\tan \theta=0.15[/tex]
Taking tan inverse on both sides.
[tex]\theta=\tan^{-1}(0.15)[/tex]
[tex]\theta=8.5307656[/tex]
[tex]\theta \approx 8.5[/tex]
Therefore, the angle of depression is 8.5 degrees.
can someone please answer this for me ?

DE is parallel to AC. Find the measure of angle x and z. Explain how you know.
Answer:
x= 67 degrees and z= 54 degrees
Step-by-step explanation:
Using alternative interior angle, you can see that x is equal to 67 degrees
-In a triangle, there is 180 degrees. Since there are 59 degrees and 67 degrees in the triangle, you will just need to solve for z.
-In order to solve for z, you subtract 180-59-67= 54

a company sells kites it sells basic and designer kites 2 basic kites and 2 designer kites are 400g 4 basic kites and 1 designer are 440g work out the weight of a basic and a designer kit
Answer:

Step-by-step explanation:
hope this answer will help u
The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
let the weight of basic kit be x and weight of designer kit be y.
The weight of 2 basic kites and 2 designer kites are 400g.
and, the weight of 4 basic kites and 1 designer kites are 440g.
So, the system of equation is
2x + 2y = 400.............(1)
4x + y = 440
y = 440 - 4x.............(2)
Solving equation (1) and (2), we get
2x + 2(440 - 4x) = 400
2x + 880 - 8x = 400
-6x = -440
x = 73.33
and, y= 440 - 4(73.33)
y = 146.68

When combining like terms how do you know to add or subtract?
Answer:
It’s depends on the sign.
Step-by-step explanation:
For example if your question is 3x+16y-8-7x+8y then the answer would be -4x+24y-8 if they have the same variable look at them as a separate equation.
Answer:
"Like Terms" means that you can add or subtract two terms. For instance, you know that you can add and get 5. You were able to add these two 'terms' ( the '2' and the '3') because they are both numbers! However, you might also know that you cannot 'combine' 2 and x. Since 2 is a number and 'x' is not, they are not like terms.
Basically if its two numbers that are the same, For example (-2x and -4x) and have with the same variables you would add them. If they are like this (5x and -2x) you would subtract them because its a negative and positive number and get ( 3x).

A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can travel 6 miles in the same amount of time it takes to travel 4 miles upstream....Use the ratio T= D/R to construct a rational equation that can be solved for x to find the speed of the current..... Whats the answer? Please answer as soon as possible...
Answer: The speed of the current is 2 miles per hour.
Step-by-step explanation:
We know that the speed of the boat is:
S = 10 mph.
When the boat travels with the current, the speed will be:
S = 10mph + x
where x = speed of the current.
When the boat travels against the current, the speed will be:
S = 10mph - x
Now, for a given amount of time T, when the boat travels with the current, it moves a distance of 6 miles.
Then we have the equation:
(10mph + x)*T = 6mi
And against the current, in the same time the boat moves 4 mi, then:
(10 mph - x)*T = 4mi
Then we have the system of equations:
(10mph + x)*T = 6mi
(10 mph - x)*T = 4mi
Now, we can take the quotient of these two equations and get:
((10mph + x)*T)/((10 mph - x)*T) = (6mi/4mi)
(10mph + x)/(10 mph - x) = 3/2
Now we can solve this for x.
(10mph + x) = (3/2)*(10 mph - x)
10mph + x = (3/2)*10mph - (3/2)*x
x + (3/2)*x = (3/2)*10mph - 10mph
(5/2)*x = (1/2)*10mph = 5mph
x = (2/5)*5mph = 2mph.
The speed of the current is 2 miles per hour.

Answer:
14 miles
Step-by-step explanation:
He can row 3.5 miles in .25 hours.
If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.
Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.
