I think the answer is 3, -8/2 / 6/-3 .... then you flip and multiply to get to -8/2 x -3/6 which = 24/8 which is equal to 3
When multiplying numbers with exponents, add the exponents.
So the answer is 2^-16
Answer:
13/4 or 3 1/4
Step-by-step explanation:
5 3/8 = 43/8
2 1/8 = 17/8
43/8 - 17/8 = 26/8
26/8 = 13/4
Answer:
a = 3, -3
Step-by-step explanation:
Multiply (a+3)/(a+3) to 2/(a-3) and multiply (a-3)/(a-3) to 2/(a+3) to get:
2(a+3)/(a-3) and 2(a-3)/(a+3) which equals (2a+6)/(a^2-9) and (2a-6)/(a^2-9)
add those two together to get (4a)/(a^2-9) which is equal to a/(a^2-9) on the other side. Cross multiply to get 4a^3 - 36a = a^3 - 9a, add/subtract like terms and you get a = 3 or -3
Answer:
1) x+2x+x+3 = 23
4x+3=23
4x=20
x=5
2) a_ radius × radius × pi = the area
4×4×3= 48
b_ diameter × pi= the circumfrence
8×3 = 24
3) a) 34_10=24
24÷3=8
b) _24_(_48)= 24
4) a) 2x=9_5
2x=4 => x=2
b)X/3 =12
x= 36
5) x. _2.
y. 3_(_2)=5
x. 0
y. 3_0=3
x. 3
y. 3_3=0
i put them here too
