Which equation is equivalent to 3(1 – x) = 2x - (6x+3)?
Answer:
3-3x=-4x-3
Please correct me if I am wrong.
Step-by-step explanation:
Option A is equivalent to 3(1 – x) = 2x - (6x+3) That is :
3 – 3x = -4x+3
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
The given equation is :
3(1 – x) = 2x - (6x+3)
multiply 3 with inside the parenthesis in the left side of equation :
3 – 3x = 2x - (6x+3)
subtract 2x with 4x and simplify :
3 – 3x = 2x - 6x+3
3 – 3x = -4x+3
this result is equivalent to option A which will give the same result.
Therefore, Option A is equivalent to 3(1 – x) = 2x - (6x+3).

Solve for t -7/4 =2/5t
Answer:
t = 35/12
Step-by-step explanation:
t - 7/4 = 2/5 t
t = 2/5 t + 7/4
t - 2/5 t = 7/4
t*(1-2/5) = 7/4
t*3/5 = 7/4
t = (7/4)/(3/5)
t = 7*5/4*3
t = 35/12

N 3 rows of 5. Colleen used tiles that measured 1 2 3 cm in length. Caroline used tiles that measured 3 1 3
Complete question :
Colleen and Caroline each built a rectangle out of square tiles placed in 3 rows of 5. Colleen used tiles that measured 1 2/3 cm in length. Caroline used tiles that measured 3 1/3 cm in length.
a. Draw the girls’ rectangles, and label the lengths and widths of each.
b. What are the areas of the rectangles in square centimeters?
c. Compare the areas of the rectangles.
Answer:
Colleen = 41.667 cm²
Carolina = 166.667 cm²
Carolina's rectangle is larger Than Collen's
Step-by-step explanation:
To start with, we determine the total number of tiles used
3 Rows of 5 ; 3 in 5 places = 15
Length of collen's square tiles : 1 2/3 = 5/3
Area of collen's square tiles = square of side length, = (5/3)² = 25/9
Area of rectangle formed = area of square * number of tiles
(25 /9) * 15 = 41.667 cm²
Length of carolina's square tiles : 3 1/3 = 10/3
Area of collen's square tiles = square of side length, = (10/3)² = 100/9
Area of rectangle formed = Area of square * number of tiles
(100/9) * 15 = 166.667 cm²
Carolina's rectangle is larger Than Collen's

If you know the measure of one of the 8 angles, you can find the measure of all of the others. Try it. The measure of <1 = 120 degrees
Answer:
[tex]\angle 2 =60[/tex]
[tex]\angle 3 = 60[/tex]
[tex]\angle 4 = 120[/tex]
[tex]\angle 5 = 120[/tex]
[tex]\angle 6 = 60[/tex]
[tex]\angle 7 = 60[/tex]
[tex]\angle 8 = 120[/tex]
Step-by-step explanation:
Given
[tex]\angle 1 = 120^\circ[/tex]
See attachment
Required
Determine the other angles
[tex]\angle 1[/tex] and [tex]\angle 2[/tex] are on a straight line.
So;
[tex]\angle 1 + \angle 2 =180[/tex]
Make [tex]\angle 2[/tex] the subject
[tex]\angle 2 =180 - \angle 1[/tex]
[tex]\angle 2 =180 - 120[/tex]
[tex]\angle 2 =60[/tex]
[tex]\angle 1[/tex] , [tex]\angle 4[/tex], [tex]\angle 5[/tex] and [tex]\angle 8[/tex] are corresponding angles.
So;
[tex]\angle 4 =\angle 1 = 120[/tex]
[tex]\angle 5 =\angle 1 = 120[/tex]
[tex]\angle 8 =\angle 1 = 120[/tex]
Similarly; [tex]\angle 2[/tex] , [tex]\angle 3[/tex], [tex]\angle 6[/tex] and [tex]\angle 7[/tex] are corresponding angles.
So;
[tex]\angle 3 =\angle 2 = 60[/tex]
[tex]\angle 6 =\angle 2 = 60[/tex]
[tex]\angle 7 =\angle 2 = 60[/tex]
