Answer:

6 and 14

Step-by-step explanation:

let the second number=x

the first number=3x-4

(x+3x-4)+5=25

4x-4+5=25

4x+1=25

4x=25-1

4x=24

x=6

Since x is the first number,the first number is 6

second number=3•6-4

=18-4=14

A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales.Write an equation that gives the w

lisabon 2012 [21]

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Step-by-step explanation:

Given,

Weekly salary of real estate agent = $250

Commission rate = 2%

Let,

x be the sales per week.

y be the total weekly income.

Amount of commission = 2% of sales per week

Amount of commission = $\frac{2}{100}*x$

Amount of commission = 0.02x

Total weekly income = Amount of commission + Weekly salary

$y=0.02x+250$

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

About 127.3(square root of 16,200, or 90√2) Look at this problem like a right triangle. Each leg is 90 feet, so the hypotenuse is the square root of 90^2 + 90^2
About 52.3(square root of 2735.64) Another right triangle problem! Once again, with Pythagorean theorem (a^2 + b^2 = c^2) You can deduce that 60^2 = 29.4^2 + the width of the TV^2.
About 11.6(Square root of 134.75)Another right triangle problem, you can deduce that 9.5^2 + The pool length^2 = 15^2

Hope it helps <3
