If I was asked to think of a number and multiply it by 2, I could write this algebraically as 2x.
Write the following algebraically using x as your unknown.
“I think of a number, multiply it by 2, subtract 3 and multiply the result by 4”
Answer:
8x - 12
Step-by-step explanation:
Let the number be x
multiply by 2
= x * 2 = 2x
Subtract 3 ;
2x-3
Multiply result by 4
=
4(2x -3) = 8x-12
please answer my question
Answer:
well 12 x 10 = 120 so 120 x 10 = 1200 and 5 x 5 = 25 so 25 x 10 = 250 and 1200 + 250 would be 1450

Step-by-step explanation:
A triangle has sides represented by 7, x, and x−1. If the perimeter is 28, find the length of the longest side.
Answer:
x (11 unit) is the longest side
Step-by-step explanation:
Given:
Sides;
7, x, and x−1
Perimeter = 28
Find:
Longest side
Computation:
Perimeter = sum of all sides
So,
7 + x + (x -1) = 28
2x + 6 = 28
x = 11
So,
x -1 = 11 - 1 = 10 unit
x (11 unit) is the longest side
Denise makes three times as many chocolate cupcakes as vanilla cupcakes. She also makes three dozen strawberry cupcakes. If Denise makes 132 cupcakes, how many dozen chocolate cupcakes does she make?
Answer:
6 dozens
Step-by-step explanation:
Vanilla, v = x
Chocolate, c = 3x
Strawberry, s = 3 dozens = 36
Total cupcakes = 132
Hence,
x + 3x + 36 = 132
4x = 96
x = 96 / 4
x = 24
Chocolate = 3 * 24 = 72
Dozens of chocolate = 72 /12 = 6 dozens

(5x + 4y = 24
2x – 7y = 26
Answer:
B.
Step-by-step explanation:
If you calculate the sum of both you get:
5x + 2x + 4y - 7y = 24 + 26
7x - 3y = 50, which is B
y=-2/3x-5 slope and y-intercept
Answer:
Slope = 2/3
Y-intercept = -5
Step-by-step explanation:
Since the equation is written in y = mx + b format. The m is the slope and b is the y-intercept. In place of m is 2/3 and in place of b is -5. Therefore, the slope is 2/3 and the y-intercept is -5.

The equation of line is y = ( -2/3 )x - 5 , where the slope is m = -2/3 and the y intercept is b = -5
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = ( -2/3 )x - 5
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
Substituting the values in the equation , we get
Slope m = ( -2/3 )
The y-intercept b = -5
Hence , the equation of line is y = ( -2/3 )x - 5

What’s the answer???
Answer:

Step-by-step explanation:
-2/3 x - 1 =19 yeah its -2over3 with x to the right then -1 = 19
Answer:
x = 30
Step-by-step explanation:
Given the expression
-2/3 x - 1 =19
We are to find the value of x
Add 1 to both sides
2/3 x -1 +1 = 19+1
2/3 x =20
Multiply
2/3x × 3 = 20×3
2x = 60
x = 60/2
x = 30.
Hence the value of x is 30

.......................
The length of arc is 9.1506 cm.
What is Length of Arc?The length of an arc refers to the distance along the curve of a circle between two points on that curve. It is a measure of the portion of the circumference of a circle or any other curved shape.
The Formula for Length of Arc is θ/360 x 2πr.
We have,
Radius = 7.9 cm
Angle = 66.4 degree
Now, length of Arc
= θ/360 x 2πr
= 66.4 / 360 x 2 x 3.14 x 7.9
= 0.18444 x 2 x3.14 x 7.9
= 9.1506 cm
Thus, the length of arc is 9.1506 cm.

Two divers are underwater. Nick is 33 feet below the surface. Tristan is 15
feet above him. What is Tristan's depth?
A
15 feet below the surface
B
18 feet below the surface
33 feet below the surface
D
48 feet below the surface
(0) А.
OB
OC
OD
Answer: 48 feet below the surface
Step-by-step explanation:
From the question, we are informed that two divers are underwater. Nick is 33 feet below the surface while Tristan is 15 feet above him.
Tristan's depth will be represented as x.
Therefore, x - 33 = 15
x = 15 + 33
x = 48
Therefore, the answer is 48 feet below the surface.
Answer:
B 18 feet below
Step-by-step explanation:
So subtract 33-15 bechas depth means below and since tristan has less of a depth to go rather than Nick you would subtrac.

Find the missing side lengths, leave your answers as radicals in the simplest form. Show work please
Answer:
m and n are both equal to 10
Step-by-step explanation:
Because we see that the two of the angles here are 45 and 90, we know then that the third angle is also 45. This tells us that the sides m and n are of equal length.
With that in mind, we can simply use the Pythagorean theorem to find their values:
m² + n² = (10√2)²
given that m = n, then:
m² + m² = (10√2)²
2m² = (10√2)²
2m² = 100 × 2
2m² = 200
m² = 100
m = 10
So both m and n are equal to 10.

Billy Bob bench presses 200 lbs. He wants to bench more than 300 lbs. If he improves by 20 lbs a month how long will it take him to bench over 300 lbs.
Write your answer like x>3 make sure you use the right sign.
WILL GIVE BRAINLIEST
it will take him 5 months
Find how much more he wants to bench:
300-200 = 100
He needs to increase by at least 100 pounds.
So 20 pounds per month has to be greater than 100 pounds.
20x > 100
Divide both sides by 20:
X > 5 months
