Answer:
x=60
Step-by-step explanation:
this is an isosceles triangle. so angle D and F are equal. D= x and F=x. so 58+x+x=180
2x+58=180
2x=122
x=60
Answer:
option A
Step-by-step explanation:
X- axis
Assuming you want to solve for x:
Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.
15x + 15 = 180
- Subtract 15 from both sides.
15x = 165
x = 11

Answer:
6 3/
5
= 6.6
Step-by-step explanation:
Conversion a mixed number 2 3/
5
to a improper fraction: 2 3/5 = 2 3/
5
= 2 · 5 + 3/
5
= 10 + 3/
5
= 13/
5
To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/
5
= 10/
5
b) Add the answer from previous step 10 to the numerator 3. New numerator is 10 + 3 = 13
c) Write a previous answer (new numerator 13) over the denominator 5.
Two and three fifths is thirteen fifths
Add: 4 + 13/
5
= 4/
1
+ 13/
5
= 4 · 5/
1 · 5
+ 13/
5
= 20/
5
+ 13/
5
= 20 + 13/
5
= 33/
5
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(1, 5) = 5. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 5 = 5. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - four plus thirteen fifths = thirty-three fifths.
