Answer:

D. 27

Step-by-step explanation:

If you plug in the variable and solve it is equal on both sides. EX.

1. 27/3 -3 = 27/9 +3

2. 9-3 = 3+3

3. 6 = 6

Answer:

X = 27

you multiply both sides and get 3x-27=x+27

then you move the terms and you get 3x-x=27+27 then calculate and get 2x=54 then divide and you get x==27

Just sub in (x+1) wherever x appears:
f(x) = 2x+4
f(x+1) = 2(x+1)+4 = 2x + 2 + 4 = 2x+6

A car salesman receives a base weekly salary of $150 plus a commission of $325 per car sold. What is the equation that models th

Temka [501]

Given :

Weekly salary , S = $150.

Commission per car , C = $325.

To Find :

The the equation that models the weekly salary of a car salesman.

Solution :

We know it is a quadratic equation :

Let , the equation is , y = mx + c

Here, x is number of car sold in a week.

For x = 0 ( He will not get commission)

So , Salary is $150 = c .

For x = 1

Salary is $( 150 + 325 ) = $475 = m(1) + c

Therefore , m = $325 and c = $150.

Required linear equation is y = 325x + 150.

Hence, this is the required solution.

The base of a right circular cylinder has a diameter of 5.00 inches. Sally measured the circumference of the base cylinder and r

LUCKY_DIMON [66]

Answer:

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

we have

$D=5\ in$

assume

$\pi=3.14$

substitute

$C=(3.14)(5)=15.7\ in$ ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

$15.7-15.5=0.2\ in$

Find the percentage by proportion

$15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%$
