Answer:
9/8
Step-by-step explanation:
divide 3/4 by 2/3
use the KCF method
so your gonna get 3/4 divided 2/3 then change the division to multiplcation and then flip the 2/3 to 3/2
now multiply across: 3/4 × 3/2=9/8
If VZ=p–7 and WY=p–21, what is the value of p?

Find the equation of this line.
y = x + [ ]
The Equation of line is y = -x + 3.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Take the points (4, -1) and (0, 3).
so, the slope of line is
m = (3+ 1)/ (0-4)
m = 4/ (-4)
m = -1
So, the equation of line
y= mx+ b
y= -x + b
and, 3 = b
So, the required equation is y = -x + 3.

Which equation represents each dimension of the larger triangle, y, based on the corresponding dimension of the smaller triangle, x?
Y= 2/3x
Y= 3x
Y= 1/3x
Y= 3/2x
How can you use the given side lengths of the triangles to check if your equation is correct?
Answer:
(b) y = 3x; check using dimensions from the figure
Step-by-step explanation:
The dimensions in the larger triangle are more than the dimensions in the smaller triangle. That means the smaller dimensions need to be multiplied by a value greater than 1 to get the larger dimension. (This eliminates the 1st and 3rd choices.)
__
EquationThe figures are drawn approximately to scale, so it is easy to see that the larger triangle's dimensions are more than double (2 times) those of the smaller triangle. (This eliminates the 4th choice. 3/2 < 2)
The equation that represents the larger dimensions in terms of the smaller ones is ...
y = 3x
__
CheckYou can check this by choosing a smaller dimension and using that in the equation:
bottom leg = 3 in

Twice the sum of a number x and 9 is equal to 12 less than the number x. What is the value of x?
Answer:
x = -30
Step-by-step explanation:
Let x be the number.
2(x + 9) = x - 12
Use distributive property of multiplication
2x + 18 = x - 12
Simplify by combining like terms
2x - x = -12 - 18
x = -30

The inequality equation is 3L ≤ 27 or L ≤ 9 feet , where L is the length
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Let the length of the equilateral triangle be L
And , each of the lengths of the triangle is at most 9 feet long means that each of the lengths is less than or equal to 9 feet
So , L ≤ 9 feet
And , the perimeter of an equilateral triangle is the addition of the three equal lengths
So , 3L ≤ 27 feet
Therefore , the value of A is 3L ≤ 27 feet
Hence , the inequality equation is 3L ≤ 27 feet

what is the equation of the line that passes through the point (-4,2) and has a slope of -5/4
Answer:
The answer is
[tex] \huge y = - \frac{5}{4} x - 3[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-4,2) and slope of -5/4
We have
[tex]y - 2 = - \frac{5}{4} (x + 4) \\ y - 2 = - \frac{5}{4} x - 5 \\ y = - \frac{5}{4} x - 5 + 2[/tex]
We have the final answer as
[tex]y = - \frac{5}{4} x - 3 \\ [/tex]
