So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right
Answer: 5/8
Step-by-step explanation:
5*3=15
6*4=24
Get 15/24 simplify and get 5/8
How to simplify it?
Divide 15 and 3
Divide 24 and 3
Get 5/8
Surface area is area so it's in^2 or inches squared
12 in=1 foot therfor
1in<1 foot
so therfor if we converted the surface area to feet, then the number would decrease, but the actual area would stay the same because we just converted the units, we didn't change the actuall area
therfor the answers are A and E
Step-by-step explanation:
(6x+4)+(4x+26)+110°=180°{straight angle}
10x+140=180°
10x=180-140
x=40/4
x=10
(6x+4)=(6×10+4)=(60+4)=64°
(4x+26)=(4×10+26)=40+26=66°
hope it helps.
