[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given expression:
3(-4x + 5) = 12
To solve for x;
Use the distributive property to open the parentheses;
3(-4x) + 3(5) = 12
-12x + 15 = 12
then, add -15 to both sides;
-12x + 15 + (-15) = 12 + (-15)
-12x = -3
divide both sides by -12;
[tex]\frac{-12x}{-12}[/tex] = [tex]\frac{-3}{-12}[/tex]
x = [tex]\frac{1}{4}[/tex]
solve for n -8 = 6+n
Answers
Answer:
no solution
Step-by-step explanation:
n -8 = 6+n
Subtract n from each side
n-n -8 = 6+n-n
-8 = 6
This is never true so there is no solution
Answer:
n = -14
Explanation:
-8 = 6 + n
move n over to the left side of the equation
-8 - n = 6
-8 - (-14) = 6

Regina’s teacher recently gave her a homework assignment on solving equations. Since she has been thinking about saving for a new cell phone, she decided to use the assignment as an opportunity to model a savings plan.
She created this equation to model the situation. In it, y represents the total amount saved for the new cell phone, 74 is the amount of money she has now, 40 is the amount of money she saves each month for the phone, and x represents the number of months since she started saving a regular amount:
74 + 40x = y.
She then solved the equation to determine how many months she’d need to save to have enough to purchase the new cell phone. Review her work, and select the error.
Answers
Answer:
The answer is 4.
Step-by-step explanation:
In her solution, there is an error in step 4. She used the multiplication property of equality but its a division property.
Given that,
A solution is given, we have to review the solution and mark the steps that contain an error.
In mathematics, it deals with numbers of operations according to the statements.
Here,
In the solution, every step is accurate and correct, except for step 4. she divided the equality by 40 and she wrote the step as multiplication property of equality which is wrong the correct statement for step 4 is the division property of equality.
Thus, in her solution, there is an error in step 4. She used the multiplication property of equality but its a division property.

Find the measure of 1 in the figure, shown to the right.
Answers
Answer:
∠1 = 81°
Step-by-step explanation:
∠1 and 81° are corresponding angles and corresponding angles are equal to each other.
The measure of ∠1 in the figure is 81°.
What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Angles are usually measured in degrees or radians.
Given is a figure of two parallel lines which is cut by a transversal line.
There are many properties for the angles formed by the transversal lines.
One of the property is that corresponding angles are equal.
Corresponding angles are the pair of angles which are on the same side of each parallel lines and at the same side of the transversal but at different intersections.
In the given figure,
∠1 and 81°, ∠3 and ∠7, ∠2 and ∠6, ∠4 and ∠8 are corresponding angles.
Since ∠1 and 81° are corresponding angles ∠1 = 81°.
Hence, measure of angle 1 is 81 degrees.

e is 5 more than d.
f is 7 less than d.
Work out
e-f
Simplify your answer.
Answers
Answer:
12+2d
Step-by-step explanation:
e=5+d
f=d-7
e-f = 5+d-(d-7)
e-f = 12+2d
The solution of expression e - f is,
⇒ e - f = 12 + 2d
We have to given that,
e is 5 more than d.
And, f is 7 less than d.
Hence, It can be written as,
e is 5 more than d.
⇒ e = 5 + d
And, f is 7 less than d.
⇒ f = d - 7
So, We get;
e - f = (5 + d) - (d - 7)
Combine like terms,
e - f = 12 + 2d
Therefore, The solution of expression e - f is,
⇒ e - f = 12 + 2d

Communities A,B and C are faced with acute water problem. The distance between communities A and B is 5km and that of A and C 7km. The angle between path AB and AC is 45degrees. If a well is dug for the three communities such that it would have equal distance to the path linking each communities. (a) Indicate by a way of sketching the exact place to dig the well? (b) Measure the distance between communities B and C?
Answers
Answer:
a) by finding the incentre
b) 5 km
Step-by-step explanation:
Let the communities A, B and C be shown by the three points of the triangle as shown in the figure below. As the angle between the path Ab and Ac is 45 degrees this is an isosceles triangle having two angles equal. As this is an isosceles triangle it must also have two sides equal .
a) the in center point can be used to have equal distance to the path linking each communities.
We take a compass and draw arcs on the two sides of the vertex and placing the compass on the arcs bisect each angle made by the triangles arms.
Joining the bisectors the lines meet at a point which is highlighted by a circle in the diagram.
This is the incentre which is equidistant from each vertex.
b) Using Pythagorus theorem
c² = a² + b²
7²= 5² + b²
b²= 24
b= 4.89= 5 km
The path between B and C is also 5 km.

You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts, and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts, and one shirt for $52. How much does each item cost?
Answers
Answer: Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
Step-by-step explanation:
Let x= cost per pair of jeans
y = Cost per pair of shorts
z= cost per shirt.
For you, total cost = x+4y+2z= 84
For your friend, total cost = 2x+y+3z=76
For cousin, total cost = x+2y+z= 52
Required system:
[tex]x+4y+2z=84\ (i)\\ 2x+y+3z=76\ (ii)\\ x+2y+z=52\ (iii)[/tex]
from (i), [tex]x=84-4y-2z[/tex] (*)
put this in (ii) and (iii) we get
[tex]2\left(84-4y-2z\right)+y+3z=76\\\Rightarrow\ -7y-z+168=76\ (iv)\\\\ 84-4y-2z+2y+z=52\\\Rightarrow\ -2y-z+84=52 \ (v)[/tex]
from (iv), [tex]y=-\frac{z-92}{7}\ (vi)[/tex]
[tex]\mathrm{Subsititute\:}y=-\frac{z-92}{7}\ \text{in}\ (v)[/tex]
[tex]-2\left(-\frac{z-92}{7}\right)-z+84=52\\\\\Rightarrow\ -2\left(-\frac{z-92}{7}\right)-z=-32\\\\\Rightarrow\ -\frac{5z}{7}-\frac{184}{7}=-32\\\\\Rightarrow\ -5z-184=-224\\\\\Rightarrow\ -5z=-40\\\\\Rightarrow\ z=8[/tex]
[tex]\mathrm{Subsititute\:}z=8\text{ in (vi)}[/tex]
[tex]y=-\frac{8-92}{7}\\\\\Rightarrow \ y=12[/tex]
[tex]\mathrm{Subsititute\:}z=8,\:y=12\text{ in (*)}[/tex]
[tex]x=84-4\cdot \:12-2\cdot \:8\\\\\Rightarrow\ x= 20[/tex]
Hence, x= 20, y= 12 , z=8
So, Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
