Answer:
Step-by-step explanation:
if anna is x years old and her sister is 5 five years older the eqasion would be x=5-5x but there is no further information for the answer. You need to know how old anna is to answer the question. Did you write it correctly
<3 +<4= 180
<3+25+52=180 from here <3=180-77=103
using this in first equation: 103+<4=180 <4=180-103=77
as you can see <4=77 which is the the sum of 25+52
The surface 5 cm, and the length is 10 cm
Answer:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
Honestly this problem you can use both x and y but x tends to be the easier one to use and i would use the first equation because it is easier to solve because all the numbers are even.<span />
