Answer:
Step-by-step explanation:
-14 + 2x + 3 = 4x - 13 - 7x
We can first add the numbers and coefficients on either side:
2x - 11 = -3x - 13
Then, we can add 3x to both sides:
5x - 11 = -13
We can add 11 to both sides
5x = -13 + 11 = -2
Lastly, we can divide both sides by 5
x = -2 / 5
[(8 - 2) x (3 +2) - 1 ]x 3
Answer:
Step-by-step explanation:
Use PEMDAS rule
First do the operations inside the parenthesis
[(8 -2 ) * (3 + 2) - 1] * 3 = [ 6 * 5 - 1]*3
Now multiplication
= [ 30 - 1] *3
= 29 *3
= 87

made. Chris received birthday money in an amount that
was of what Ashley made. How much birthday money
did Chris receive?

A carpenter has a wooden plank that is 1 m long, 12 cm wide and 4 cm thick. The LENGTH : WIDTH : THICKNESS ratio of the plank is
A 1:12:4
B 1:3:1
C 25:3:1
D 25:12:1
The solution is Option A
The ratio of length : width : thickness of the plank is 1 : 12 : 4
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the length of the plank = 1 cm
The width of the plank = 12 cm
The thickness of the plank = 4 cm
Now , the proportion is given as
The ratio of length : width : thickness of the plank = 1 : 12 : 4
Therefore , the value of A is 1 : 12 : 4
Hence , the proportion is 1 : 12 : 4
