Since the bases on either side match (5), the exponents must be equal. So
3b - 1 = b - 3
Solve for b :
3b - b = -3 + 1
2b = -2
b = -1
Let us see the answer choices please
Since S is a point on the line RT, therefore:
RS+ST = RT
5y+5+3y+7 = 12y-20
separate the variables and solve to get thevalue of y as follows:
5+7+20 = 12y-3y-5y
32=4y
y = 8
substitute in the equation of each line to get its length as follows:
RS = 5y+5 = 5(8)+5 = 45
ST = 3y+7 = 3(8)+7 = 31
RT = 12y-20 = 12(8)-20 = 76
Answer:
fifth option
Step-by-step explanation:
Given
- 2(x - 5) ≤ 6x + 18 ← distribute left side
- 2x + 10 ≤ 6x + 18 ( subtract 6x from both sides )
- 8x + 10 ≤ 18 ( subtract 10 from both sides )
- 8x ≤ 8
Divide both sides by - 8, reversing the sign as a result of dividing by a negative quantity, thus
x ≥ - 1
Answer:
72
Step-by-step explanation:
Multiply 8 and <em>n </em>to get 8n
Multiply 3 and 192 to get 576
Write them equal to each other 
To isolate the variable divide by 8 on both sides
