Which value of x makes this sentence true?
2 answers:
Answer:
9/22
Step-by-step explanation:
1/2 + x=10/11
Subtract 1/2 from each side
1/2-1/2 + x=10/11-1/2
x = 10/11 -1/2
Getting a common denominator of 22
x = 10/11*2/2 -1/2 *11/11
x = 20/22 - 11/22
x = 9/22
Answer:
x=9/22
Step-by-step explanation:
u have to subtract 1/2 on both sides, so u can get X by itself
1/2-1/2+x=10/11-1/2
get the common denominator for 10/11 and 1/2
10/11 times 2/2=20/22
1/2 times 11/11=11/22
20/22-11/22= 9/22
x=9/22
ANSWER CHECK
substitute the variable X for 1/22
1/2+9/22=10/11
common denominator
1/2 times 11/11=11/22
11/22+9/22= 20/22 or 10/11

Answer:
b = 6i then a = -6i
b = -6i then a = 6i
Step-by-step explanation:
a+b=0
ab=36
a = -b
a(b) = 36
-b * b = 36
- b^2 = 36
b^2 = -36
Take the square root of each side
sqrt(b^2) = sqrt(-36)
b =± 6i
a = - (± 6i)
so b = 6i then a = -6i
b = -6i then a = 6i
50=t/2+8
50-8=t/2
42=t/2
2×42=t
84=t
check: 50=84/2+8
50= 42+8
50=50
