Answer:
x=42
Your welcome!
Answer:
x=42
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4/7*x+5/14*x-(39)=0
Simplify 5/14
((4/7• x) + (5/14 • x)) - 39 = 0
Simplify 4/7
4 5x
((— • x) + ——) - 39 = 0

Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 4x • 2
—————————————————— = ——————
L.C.M 14
R. Mult. • R. Num. 5x
—————————————————— = ——
L.C.M 14
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4x • 2 + 5x 13x
——————————— = ———
14 14
13x
——— - 39 = 0
14
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 14 as the denominator :
39 39 • 14
39 = —— = ———————
1 14
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
13x - (39 • 14) 13x - 546
——————————————— = —————————
14 14
Pull out like factors :
13x - 546 = 13 • (x - 42)
13 • (x - 42)
————————————— = 0
14
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
13•(x-42)
————————— • 14 = 0 • 14
14
Now, on the left hand side, the 14 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
13 • (x-42) = 0
Solve : 13 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-42 = 0
Add 42 to both sides of the equation :
x = 42

How many years will it takes an investment of 3000$ to amount to 5,000 if money is invested at 4.1% compounded monthly
Answer:
1.66
Step-by-step explanation:
The years needed to make $3000 to $5000 is 12.5.
What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly
A = P(1+r/12)^12t
5000 = 3000(1+0.041/12)^12t
5/3 = (1.0034)^12t
Taking log both sides,
log5/3 = 12tlog(1.0034)
0.221 = 12t0.00147
12t = 150.34
t = 12.5
Hence, required years are 12.5.

A rate is a ratio that compares
Rate is ratio that compares two quantities of different units.
What is rate?A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units
For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.
The unit of distance is metres and the unit of time is second. Therefore ;
velocity = distance /time. Therefore velocity is a rate.
Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is
1 day = 5/20
= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.

Find the lenght of side BC. give your answer to 3 significant figures
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )
What is the slope of a line perpendicular to the line whose equation is x-2y=12? Fully reduce your answer
Answer:
First, we need to solve the equation in the problem for y to put it in slope-intercept form so we can determine its slope:
2y−6x=4
2y−6x+6x=6x+4
2y−0=6x+4
2y=6x+4
2y2=6x+42
2y2=(6x2)+(42)
y=3x+2
The slope-intercept form of a linear equation is: y=mx+b
Where m is the slope and b is the y-intercept value.
Therefore the slope of this equation is m=3
A perpendicular line will have a slope (let's call this slope mp) that is the negative inverse of this line. Or, mp=−1m
Substituting gives:
mp=−13
