The solution to the equation is B)x=-4.
What is equation ?
Equations are mathematical expressions that have two algebraic expressions on either side of an equals (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left hand side = right hand side) is a fundamental mathematical formula. For an unknown quantity represented by an unknown variable, equations can be solved to determine its value. It is clear that a statement is not an equation if there is no "equal to" sign in it. The phrase will be regarded as an expression.
Here the given equation is,
[tex]= > \frac{1}{4}x - \frac{1}{8}= \frac{7}{8}+\frac{1}{2}x\\ = > \frac{1}{4}x-\frac{1}{2}x = \frac{7}{8}+\frac{1}{8} \\ = > \frac{1-2}{4}x = \frac{7+1}{8} \\= > \frac{-1}{4}x=\frac{8}{8}\\= > \frac{-1}{4}x=1\\ = > x= -4[/tex]
Hence the solution of the equation is B)x=-4.

An army base had provisions for 300 soldiers for
90 days. After 20 days, 50 soldiers left the army base.
How much longer after this will the food last if the
remaining soldiers consume food at the same rate?
Answer:
Step-by-step explanation:
An army base had provisions for 300 soldiers for 90 days. After 20 days, there should be provisions enough for 300 soldiers for another 70 days
= 21000 soldier-day
50 soldiers left so there are 300-50 = 250 soldiers left
if they consume food at the same rate, the remaining provisions will last
= 21000/250
= 84 days

Answer:
138°42°Step-by-step explanation:
Angle WXY and YXZ form a supplementary angle. This is when two angls add up to be 180°.
We can write an equation and solve for x.
8x - 14 + 2x + 4 = 180
~Combine like terms
10x - 10 = 180
~Add 10 to both sides
10x = 190
~Divide 10 to both sides
x = 19
Find both angles.

The Bakers want to sell their house for $145,500. After 2 months, the Bakers decided to mark down the price of their house 8% to sell more
quickly. How much are the Bakers selling their house for now?
Answer:
The Bakers are now selling their house for $133,860
Step-by-step explanation:
Percentage
The original price for The Bakers' house was $145,500.
Later they decided to mark down the price of the house by 8%.
Since the new price will be 8% less than the original price, we can calculate the markdown as follows:
8 * $145,000 / 100 = $11,640
The new price is calculated as the original price minus the markdown:
New price = $145,500 - $11,640 = $133,860
The Bakers are now selling their house for $133,860

A).1+ 4x+2/2x=5x
b).2x-2+3x/4=2x
A.
Divide the numbers
1 + 4x 2/2 • x =5x
1 + 4x + 1x =5x
Multiply by 1
1 + 4x + 1x=5x
Combine like terms
1 + 4x + x =5x
1 + 5x =5x
Subtract 1 from both sides of the equation
5x + 1 = 5x
5x + 1 - 1 =5x -1
Simplify
Subtract the numbers
5x = 5x -1
Subtract 5x from both sides of the equation
5x = 5x -1
5x - 5x = 5x -1 -5x
Simplify
0= -1
Result
0= -1
