The quadrilaterals JKLM and PQRS are similar.
Find the length x of RS.
Will mark brainliest!
The measure of side x equivalent to RS is 42
Similar shapes are shapes that have both their sides and angles to be equal.
Since both quadrilaterals JKLM and PQRS are similar, we will take the ratio of the sides as shown;
4/24 = 7/x
1/6 = 7/x
Cross multiply
x = 42
Hence the measure of side x equivalent to RS is 42

Hello there, this is how we would solve this problem, we can see that angle KAE equals 90° and we have an angle that equals 62° now since angle GCJ or also known as x is a vertical angle with IAD we can make the following equation
[tex]x+62+90=180[/tex] subtract 62 and 90 from both sides and we get that [tex]x=28[/tex]°

use the midpoint formula to find the midpoint of the given segment on the coordinate plane
Answer:
Midpoint : (4,3)
Step-by-step explanation:
midpoint = [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
Where the x and y values are derived from the given points.
We are given points H and K which are at (2,2) and (6,4)
We have (x1,y1) = (2,2) so x1 = 2 and y2 = 2
As well as (x2,y2) = (6,4) so x2 = 6 and y2 = 4
To find the midpoint we simply plug in the values of x and y into the formula
Recall the formula [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
x1 = 2 , x2 = 6 , y1 = 2 and y2 = 4
plug in these values into the formula
[tex](\frac{2+6}{2} ,\frac{2+4}{2} )[/tex]
add top values: 2 + 6 = 8 and 2 + 4 = 6
[tex](\frac{8}{2} ,\frac{6}{2} )[/tex]
simplify fractions : 8/2 = 4 and 6/2 = 3
The midpoint is at [tex](4,3)[/tex]
What is the equation of the line that passes through (-6,-2) and had a slope of -1/6
Answer:
[tex]y = -\frac{1}{6}x - 3[/tex]
Step-by-step explanation:
Slope Intercept Form : [tex]y = mx + b[/tex]
Using our slope, -1/6, input it for m, then plug the point (-6, -2) for x and y
[tex]y = mx+b\\\\-2 = (-1/6)(-6) + b\\\\-2 = 1 + b\\\\b = -3[/tex]
Equation : [tex]y = -\frac{1}{6}x - 3[/tex]

Answer:
x = 5
Step-by-step explanation:
Δ EAB and Δ EDC are similar by the AA postulate , so the ratio of corresponding sides are in proportion , that is
[tex]\frac{AB}{DC}[/tex] = [tex]\frac{EA}{ED}[/tex] , substitute values
[tex]\frac{10}{4}[/tex] = [tex]\frac{2x+10}{x+3}[/tex] ( cross- multiply )
10(x + 3) = 4(2x + 10 ) ← distribute parenthesis on both sides
10x + 30 = 8x + 40 ( subtract 8x from both sides )
2x + 30 = 40 ( subtract 30 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Alejandro bought $3. 50 worth of pencils and erasers at the school store. Pencils cost $0. 50 apiece, and erasers cost $0. 75 apiece. Which equation written in standard form represents the number of pencils, p, and the number of erasers, e, that Alejandro bought? 0. 75e = 3. 50 â€" 0. 50p 0. 50p 0. 75e = 3. 50 3e = 14 â€" 2p 2p 3e = 14.
Answer:
2p + 3e = 14
Step-by-step explanation:
The required equation is [tex]0.50\ p+0.75\ e= 3.50\\[/tex]
Given, Alejandro bought $3.50 worth of pencils and erasers at the school store.
The cost of each pencil is $0. 50.
The cost of each eraser is $0. 75.
Since He denotes no. of pencil by p and no. of eraser by e, so the required equation will be,
[tex]0.50\ p+0.75\ e= 3.50\\[/tex].
Hence the required equation is [tex]0.50\ p+0.75\ e= 3.50\\[/tex]
