Answer:
x = 4
Step-by-step explanation:
The midsegment ( median is equal to half the sum of the parallel bases, that is
= EF, substitute values
= 13 ( multiply both sides by 2
7x - 2 = 26 ( add 2 to both sides )
7x = 28 ( divide both sides by 7 )
x = 4
Answer:
Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the smallest angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
one angle is 130 degrees more than the smallest angle
----> equation B
the third angle is 3 times as large as the smallest angle
---> equation C
substitute equation B and equation C in equation A
solve for y
Find the value of x
Find the value of z
therefore
Answer: 94 questions
Step-by-step explanation:
is %
----- = -----
of 100
64 68 68 is the percent Alyssa got correct on the exam.
----- = ----- 64 is the questions she got wrong of an unknown total.
x 100 x is the unknown variable. (the total questions on the test)
Cross multiply to get this: 64*100 = 68x
6400 = 68x (Divide by 68 on both sides)
You should get about 94.11 after dividing. You have to round as there cannot be have a question. It should be rounded to 94 questions. There are 94 questions and 64 were missed. To check your work, do 64/94. This should give you about 68% after rounding.
If dey colinear then
AE=AC+CE
so if AE=x+50 and CE=x+32 then
x+50=AC+x+32
minus x both sides
50=AC+32
minus 32 both sides
18=AC
AC=18 units
Answer:
B
Step-by-step explanation:
Both simplify to 3/8
