Answer:

FE = 10, DE = 24

Step-by-step explanation:

We can use ratios to solve

13 5

----- = ----------

26 FE

Using cross products

13 FE = 26*5

Divide each side by 13

13 FE/13 = 26*5/13

FE = 10

13 12

----- = ----------

26 DE

Using cross products

13DE = 12*26

Divide each side by 13

13 DE/13 = 26*12/13

DE = 24

Answer:

D. DE = 24 yd, EF = 10 yd

Step-by-step explanation:

Solve for the unknown angles by setting up common ratios and cross multiplying. You can use this method because they are similar triangles.

For example, DE can be found by setting the ratios of AC/AB equal to the ratio of DF/DE.

13/12 = 26/x

Simply solve for x!

What is the value of x in the solution to the system of linear equations? {y=3x+2 y=x-4 a –7 b –3 c 1 d 5

lyudmila [28]

Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have

$3x+2=x-4 \iff 2x+2=-4 \iff 2x=-6 \iff x=-3$

Molodets [167]

Step-by-step explanation:

It is an isosceles triangle , it has two equal angles both 55°.

All Isosceles triangles have two equal angles and two equal sides.

So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.

x + 18 = 3x

x - 3x = -18

-2x = -18

× = -18 / -2

× = 9 (ans)

Hope I was able to help. Good Luck :)))

What are the parallel sides of a trapezoid

saul85 [17]

Answer:

Parallel means that the lines will never cross. If we look at a traditional trapezoid, the top side and the bottom side are straight lines that will never cross one another. The left and right sides are slanted towards one another, to they are not parallel.

Hope this helped. : )

The pie chart shows information about voters in an election. 2800 more women vote than men. Work out the total number of voters.

Dmitry [639]

The picture in the attached figure

let
x--------> men voters
y-------> women voters

we know that
y=x+2800------> y-x=2800------> equation 1

step 1
find the percentage of women and men voters
in the graph
central angle by men voters=130°
central angle by women voters=(360°-130°)-------> 230°
by using proportion
men voters
$\frac{360}{100} = \frac{130}{M} \\ M=(100*130)/360 \\ M=36.11$ %

women voters
$\frac{360}{100} = \frac{230}{F} \\ F=(100*230)/360 \\ F=63.89$ %

remember equation 1
y-x=2800
so
F-M=63.89%-36.11%----> 27.78%

if 27.78% correspond to 2800 voters
100%---------------------->T
T=100*2800/27.78-------> T=10,079.19 voters

the answer is
about 10,079 voters
