3. If 6x + 4 = 20 − 2x, then x = ?
a. 2
b. 6
c. 8
d. 16
e. 24
Answer:
a
Step-by-step explanation:
[tex]6x+4=20-2x[/tex]
Add 2 to each side
[tex]8x+4=20[/tex]
Subtract 4 from each side
[tex]8x=16[/tex]
Divide 8 by each side
[tex]x=2[/tex]
Answer:
a
Step-by-step explanation:
Your goal is to isolate the variable(x). If you subtract 4 from the left side and right side, then you are left with , 6x=16-2x. Then you add 2x to both sides to get 8x=16. Lastly divide both sides by 8 to get x=2. Hope this helps :)

What is the equation of the line that passes through the point (4, -4) and has a slope of -5/2
Answer:
y = -5/2x + 6
Step-by-step explanation:
y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b

Three friends rent a movie from $6.49 and buy some microwave popcorn for $1.82. They share the cost equally. How much should each person pay?
Answer:
$2.77
Step-by-step explanation:
Three friends rent a movie from $6.49 and buy some microwave popcorn for $1.82. They share the cost equally.
The total cost is calculated as:
$6.49 + $1.82
= $8.31
Therefore, the amount each person pay equally is calculated as:
Total amount/3 friends
$8.31/3
= $2.77

Biking at 10 mph, it takes Kristen 1/4 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/4 hour for her to get to work when the train travels 20 mph. How far does Kristen travel to work?
Answer:
Kirsten travels 7.5 miles to go to work.
Step-by-step explanation:
Bike: 10 MPH
Time: 1/4 Hour
1/4 of 10 = 2.5
Distance travelled on bike: 2.5 miles
Train: 20 MPH
Time: 1/4 Hour
1/4 of 20 = 5
Distance travelled by train: 5 miles
Add the distances together.
5 + 2.5 = 7.5
7.5 miles

A computer program in Shannon’s computer carries out a single mathematical operation in 1.5 × 10-6 seconds. How much time would the program take to complete 2.5 × 103 mathematical operations?
1/1.5 * 10^-6 = 2500/x
x = 1.5 * 10^-6 * 2500
x = 0.00375 or 3.75 * 10^-3 second.
You and your friends go to the state fair. It costs $6 to get into the fair
and $2 each time you go on a ride. Consider the relationship between
number of rides and total cost.
Model the equation to show the linear relationship.
Answer:
[tex]let \: number \: of \: rides \: be \: \: n \\ let \: cost \: be \: \: c \\ n \: \alpha \: c \\ n = kc \\ k \: is \: a \: costant \: of \: proportionality \\ when \: n = 1. \: \: c = 2 \\ 1 = (k \times 2) \\ k = \frac{1}{2} \\ therefore : \\ n = 0.5c[/tex]
Answer:
[tex]\huge\boxed{\sf x = 6 + 2y}[/tex]
Step-by-step explanation:
Let the total cost be x and number of rides be y
It costs $2 on each ride. So, the rides' cost will be:
=> Number of rides * One rides' cost
=> y * 2
=> 2 y
So, The total cost will be:
Total cost = Entrance cost + Rides' cost
Total cost = $6 + $2(Number of rides)
x = 6 + 2y

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation? The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem. The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem. The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation. The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
Answer:
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.ep 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.

describe the transformation of f(x) = sin x to g(x) = sin ( x + pi/3)
The function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a primary function:
f(x) = sinx and
The transformed function is:
[tex]\rm g(x) = sin(x+\frac{{\pi} }{3} )[/tex]
If we replace x to [tex]\rm x + \frac{\pi}{3}[/tex] it will shift to the left by π/3 units.
For a period of the transformed function is given by:
[tex]\rm T = \frac{2\pi}{n}[/tex]
Where n is used to find the period of the function.
n = 1
t = 2π
Thus, the function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π

Can someone please explain this question to me?
The image is attached.
Answer:
13
Step-by-step explanation:
Given the expression;
2 1/3 : 4 1/3 = 7 : x
Wea re to look for x;
Convert to improper fractions;
7/3 : 13/3 = 7:x
7/3 * 3/13 = 7/x
7/13 = 7/x
Cross multiply
7x = 13 * 7
7x = 91
x = 91/7
x = 13
Hence the unknown value is 13

A fruit salad recipe calls for 3/4 pound of apples and 2/5 pound of dates. What is the least common denominator of the fractions?
Given:
A fruit salad recipe calls for [tex]\dfrac{3}{4}[/tex] pound of apples and [tex]\dfrac{2}{5}[/tex] pound of dates.
To find:
The least common denominator of the fractions.
Solution:
The given fractions are:
[tex]\dfrac{3}{4}[/tex] and [tex]\dfrac{2}{5}[/tex]
The denominators of these fractions are 4 and 5 respectively.
Factor form of 4 is 2×2.
5 is a prime number, so factor form of 5 is 5×1.
Now, the least common denominator of the fractions is:
[tex]LCD=2\times 2\times 5[/tex]
[tex]LCD=20[/tex]
Therefore, the least common denominator of the fractions is 20.
