The answer 45 and the other one to the question is invalid
X = 2
Using the trapezoid mid segment theorem, knowing that the mid segment is parallel to the bases and half as long as the sum of the lengths of the bases, we add the lengths of the two bases and set it equal to two times the length of the mid segment.
7x+3+ 15= 16(2)
7x+18= 32
Subtract 18 from both sides.
7x = 14
Divide both sides by 7.
X = 2.
You can check your work by solving for the length of the base 7x + 3.
7(2)+3 =17
Then, add the length of the two bases together.
15 + 17 = 32. Half of 32 equals sixteen, which is your mid segment.
(correct me if i’m wrong, i got the theorem off of the internet and did the rest of the work myself.)
The answer is 49
Hope this helps
Answer:
Below in bold.
Step-by-step explanation:
Standard form is Ax + By = C
where A, B and C are integers and A must be positive.
So the first 2 are already in standard form but the last 2 can be converted to standard form by multiplying each term by -1:
-12x+3y=27
= -1*-12x + -1*3y = -1*27
12x - 3y = -27 is the answer.
The last one is:
24x + 12y = -60.
Answer:
6/50 simplified to 3/25
Step-by-step explanation:
step 1 Address input parameters & values.
Input parameters & values: The decimal number = 0.12
step 2 Write it as a fraction
0.12/1
step 3 Multiply 100 to both numerator & denominator
(0.12 x 100)/(1 x 100) = 12/100
It can be written as 12% = 12/100 or 12/100
step 4 To simplify 12/100 to its lowest terms, find LCM (Least Common Multiple) for 12 & 100.
4 is the LCM for 12 & 100
step 5 divide numerator & denominator by 4
12/100 = (12 / 4) / (100 / 4)
= 3/25
3/25 is a simplest fraction for the decimal point number 0.12
