Area = length * width
length = (2 * width) - 1
Since length cannot be negative, w = -2 is not a solution. Thus,
is your width.
Since length = 2 * width - 1, plug in width:
Answer:
For the First Question:
x = 61
y = 61
For the Second Question:
x = 12
y = 7
Step-by-step explanation:
Second question:
96 = 11y + 19
11y = 77
y = 7
96 = 8x
x = 12
Answer:
The measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
Step-by-step explanation:
Given that,
∠AOC = 31°
∠BOC = 2x+10
∠AOB = 4x-15
As we can seen from the figure that,
∠AOC = ∠AOB + ∠BOC
Put all the values,
31 = 4x-15+2x+10
31 = 6x-15
31+15 = 6x
46 = 6x
x = 7.7
∠BOC = 2(7.7)+10 = 25.4°
∠AOB = 4(7.7)-15 = 15.8°
So, the measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
Answer:
x < 6/7
Step-by-step explanation:
Multiply both sides by 3 to get 7x < 6
Divide by 7
x < 6/7
