Answer:
x=13
Base=25
Leg=21
Step-by-step explanation:
Firstly, since the triangle is an isosceles triangle, both legs measure the same. So we can write:
[tex]3x-18=21\\3x=39\\x=13[/tex]
With x being solved, we can substitute it into the leg and the base:
Base:
[tex]2(13)-1\\26-1\\25[/tex]
Leg (Since the other leg is 21, we can just conclude this leg to also be 21):
[tex]3(13)-18\\39-18\\21[/tex]

quotient of 7x^2 divided by 3x-5/x+3?
The quotient can be calculated by dividing the dividend with the divisor. Quotient = Dividend ÷ Divisor.
When splitting polynomials, how do you determine the quotient?The quotient and remainder are then calculated as follows:
Divide the first term of the dividend by the divisor's highest term (the one with the largest power of x, which in this case is x)
Multiply the divisor by the result got just now (the first term of the eventual quotient).
According to the Quotient Rule, the derivative of a quotient equals the denominator times the numerator's derivative minus the numerator times the denominator's derivative, all divided by the denominator's square.

Answer:
(3 m)/4 = 5/6
Step-by-step explanation:
Solve for m:
(3 m)/4 = 5/6
Multiply both sides of (3 m)/4 = 5/6 by 4/3:
(4×3 m)/(3×4) = 4/3×5/6
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) m = 4/3×5/6
4/3×5/6 = (4×5)/(3×6):
(4×3 m)/(3×4) = (4×5)/(3×6)
(4×3 m)/(3×4) = (3×4)/(3×4)×m = m:
m = (4×5)/(3×6)
The gcd of 4 and 6 is 2, so (4×5)/(3×6) = ((2×2) 5)/(3 (2×3)) = 2/2×(2×5)/(3×3) = (2×5)/(3×3):
m = (2×5)/(3×3)
3×3 = 9:
m = (2×5)/9
2×5 = 10:
Answer: m = 10/9

A rectangle has a width of 24 inches and a height of 12 inches. A second rectangle is proportional to the first and has a width of 6 inches. What is the height of the second rectangle
The height of the second rectangle is 3 inches.
How to solve the side of a rectangle?The rectangle has a width of 24 inches and a height of 12 inches. A second rectangle is proportional to the first and has a width of 6 inches.
The height of the second rectangle can be found as follows:
Two variables have a proportional relationship if the ratios of the variables are equivalent.
Hence, using the proportion,
let
x = height of the rectangle
24 / 12 = 6 / x
24x = 12 × 6
24x = 72
divide both sides by 24
x = 72 / 24
x = 3 inches
Therefore,

Let 53 - 65 he would get 12 x $54000 = $648000
Now, with part time job,
3 years to earn minus $30,000
64800 - 30000 = $618000 {total cost}
He still have 9 years to work .

Find the numbers whose sum is 9, if

equals 22.
Therefore , the solution of the given problem of linear equation comes out to be the numbers are -2 and 14.
A linear equation definition.The equation y=mx+b is the basis of a linear regression model. The y-intercept is m, and the slope is B. Although y and x are different elements, the previous sentence is frequently alluded to as a "maths problem with two variables. In bivariate linear equations, there are only two variables. The solutions of the application domains of linear equations are always zero.
Here,
Let x and y be the first and second numbers, respectively. The information provided lets us know that:
=> 3x + 2y = 22
Additionally, we are aware that the two numbers add up to 9, therefore
=> x + y = 9
We can employ a strategy like substitution to discover the values for x and y. One equation with one variable can be solved, and the solution can then be used as an expression in the other equation.
The first equation for y can be solved as follows:
=> y = (22 - 3x)/2
After that, change y in the second equation to the following expression:
=> x + (22 - 3x)/2 = 9
When we simplify and find x, we obtain:
=> 2x + 22 = 18
=> x = -2
Knowing that x = -2, we may re-apply it to the initial equation to determine the y :
=> y =28/2 =14.

You drive from City C to City A at an average speed of 140 km per hr. The exchange rate is 0.85 Euro per $1. 1) How far is the total distance in Kilometers? 2) How much will you spend on gas in euros? 3) How long will it take you to make the round trip not including any rest? Driving time only in minutes. 4) Suppose that while you are in City B you find out that you do not need to go to city C and decide to keep your initial car and drive back to City A. How much will this trip cost for gas in euros?
Answer:
Total distance = 250 miles + 175 miles + 320 miles = 745 miles = 1207.2 km
Total cost = (250 miles / 10 km/L * 4.25 $/gal + 175 miles / 18 km/L * 4.25 $/gal + 320 miles / 24 km/L * 4.25 $/gal) * 0.85 Euro/$ = €113.55
Total driving time = (250 miles / 120 mph * 60 min/hr + 175 miles / 100 mph * 60 min/hr + 320 miles / 140 mph * 60 min/hr) = 5.0417 hours = 304 min
Cost of trip back to City A = 250 miles / 10 km/L * 4.25 $/gal * 0.85 Euro/$ = €52.88
