Answer:
x = - 2 or x = 4
Step-by-step explanation:
the expression inside the absolute value can be positive or negative
Removing the bars and solve x - 1 = ± 3
x - 1 = - 3 or x - 1 = 3
x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2
x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4
Answer:
I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.
S = 19
B = 9
Step-by-step explanation:
Suzy is ten years older than Belly:
(1) S = B + 10
the next year she will be twice as old as Billy
(2) S + 1 = 2 (B + 1)
solving the system of equation (1) and (2):
Making (2) - (1):
1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10 => 1 = B - 8 => B = 9
replacing in (1) S = 19
A perpendicular slope is a slope that is the negative reciprocal of the current slope. Therefore, 3.
Answer:
Step-by-step explanation:
Total Students in Class = 25+ 15=40
Probability= (Number of Girls in Class) ÷ (Total students in Class)

Answer:
The sum must be greater than 1
Step-by-step explanation:
Two fractions that are greater than 1/2 let's say
<u>Example 1</u>
3/4 and 7/8, the sum will be
3/4+7/8 with LCM of denominator as 8 sum=
which is more than 1
<u>Example 2</u>
6/9 and 5/8 with the LCM of denominator as 72, the sum=
which is greater than 1
<u>Example 3</u>
8/9 and 7/9 with the LCM of denominator as 9, the sum=
which is greater than 1
