Answer: 5x-15=10
5x=25
x=5
Step-by-step explanation: i showed the steps above. i hope you can understand it and this helps :) *the very first step is to distribute the 5 to everything in the parentheses
Answer:
x=5
Step-by-step explanation:
5.(x-3)=10
5x-15=10
+15 +15
5x=25
Divide both sides by 5
x=5
what is the equation for 15% of 24
Answer:
5 / 5 = 100% Nov 18 11:54 UTC (GMT)
15 / 24 = 62.5% Nov 18 11:54 UTC (GMT)
255 / 280 = 91.071428571429% Nov 18 11:54 UTC (GMT)
0.067 = 6.7% Nov 18 11:54 UTC (GMT)
51 / 50 = 102% Nov 18 11:54 UTC (GMT)
Answer:
24 times .15
Step-by-step explanation:
15% is equal to .15, and in this case, if you are trying to find the answer, it is 3.6
n − 2/3 = 25 3/4 help now
Answer:
26 5/12
Step-by-step explanation:
n − 2/3 = 25 3/4 Add 2/3 to both sides
n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine
n = 25 3/4 + 2/3
Work with the fractions
3/4 + 2/3 The lowest common denominator is 12
(3*3)/(3*4) = 9 / 12
(2*4)/(3*4) = 8/ 12
9/12 + 8/12 = 17/12 = 1 5/12
Now you need to add 1 to 25
1 + 25 = 26
And add the fraction 5/12
The answer is 26 5/12
Rectangle ABCD is dilated with center at (0, 0) and scale factor 2. Select the three statements that are true about the dilation.
Answer:
Options (3), (4) and (6)
Step-by-step explanation:
Coordinates of the vertices of the given rectangle are,
A(1, 5), B(3, 2), C(-3, -2) and D(-5, 1)
When rectangle ABCD is dilated by a scale factor of 2 about the origin,
Rule to be followed for the dilation,
(x, y) → (2x, 2y)
Therefore, image of the rectangle ABCD will be,
A(1, 5) → A'(2, 10)
B(3, 2) → B'(6, 4)
C(-3, -2) → C'(-6, -4)
D(-5, 1) → D'(-10, 2)
- Hence point B' is located at (6, 4).
- Rectangle ABCD and A'B'C'D' are similar as all the angles of image will be same as the pre-image after rigid transformation (dilation).
- Let the equation of the line B'C' is,
y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{4-2}{6-3}[/tex]
= [tex]\frac{2}{3}[/tex]
Since B'C' will pass through origin, y-intercept will be zero.
Therefore, equation of B'C' will be,
y = [tex]\frac{2}{3}x[/tex]
Options (3), (4) and (6) are the correct options.
Answer:
well im confused but dont you have to find the prime too
Step-by-step explanation:
Here is a system of linear equations:
equation 1: 2x + 7y = 8
equation 2: 2x + y=14
Solve this system with either the substitution method
OR the elimination method. Type your answer as an
ordered pair, then explain how you found the solution to
the system.
Answer:
X=7.5 y=-1
Step-by-step explanation:
[tex]2x + 7y = 8 \\ 2x + y = 14[/tex]
I multiplied the equation with - 1 to than I sum it with the second one to get rid of x
[tex] - 6y = 6 \\ y = - 1[/tex]
Now you put Y in on of the equation and you get x.
[tex]2x - 1 = 14 \\ 2x = 15 \\ x = 7.5[/tex]
The length of a rectangle is three times its width the length is 3 3/4 feet. What is the area if the rectangle?
Answer:
A = 4 11/16 or 4.6875
Step-by-step explanation:
3 3/4 = 3W
divide both sides by 3
15/4 divided by 3 = W
15/4 x 1/3 = W
5/4 = W
A = L x W
3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type. ___NaI + ___Pb(SO4)2 ⟶ ___PbI4 + ___Na2SO4
Answer:
4112
Step-by-step explanation:
Answer:
By applying law of conservation of mass.
Explanation:
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.
This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balanced chemical equation follows:
4Na1+Pb(SO4)__Pb14+2Na2SO4
On reactant side:
Number of sodium atoms = 4
Number of iodine atoms = 4
Number of lead atoms = 1
Number of sulfur atoms = 2
Number of oxygen atoms = 8
On product side:
Number of sodium atoms = 4
Number of iodine atoms = 4
Number of lead atoms = 1
Number of sulfur atoms = 2
Number of oxygen atoms = 8
Hence, the balanced chemical equation is written above.
Step-by-step explanation:
A customer requires a car service for 80 miles,
How much money will the customer save by taking Sal's Car Rides instead of Ray's Limo? Enter the answer in the box.
Answer:
$25
Step-by-step explanation:
Derive an equation to represent the cost of using each ride.
Sal's Car Rides:
Using 2 pairs of values from the table, (0, 40) and (20, 80), find the slope, m (fee per mile).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{80 - 40}{20 - 0} = \frac{40}{20} = 2 [/tex]
The y-intercept, b, is the one-time fee for fuel. This is the value of the cost ($) when number of miles traveled is 0.
Thus, b = 40.
Substitute m = 2, and b = 40 into [tex] y = mx + b [/tex].
Equation for the total cost for Sal's Car Rides would be:
[tex] y = 2x + 40 [/tex].
Find the total cost to be charged if a customer requires the a car service for 80 miles if he chooses Sal's Car Rides.
Simply substitute x = 80 in [tex] y = 2x + 40 [/tex].
[tex] y = 2(80) + 40 = 200 [/tex]
The customer would pay $200.
Ray's Limo:
The equation that represents the total cost (y) to be charged for number of miles (x), given that $2.50 is charged per mile plus a one-time fee of $25 for fuel, would be:
[tex] y = 2.5x + 25 [/tex].
If a customer uses Ray's Limo services for 80 miles, the cost charged would be:
Substitute x = 80 in [tex] y = 2.5x + 25 [/tex].
Thus:
[tex] y = 2.5(80) + 25 = 225 [/tex].
The fee the customer would pay = $225 for using Ray's Limo services.
Therefore, if the customer takes Sal's Car Rides instead of Ray's Limo, he would save, $225 - $200 = $25.
The customer would save $25.
