45. Using order of operations.
Answer:
25 ≥ 0.90b + 2m
Step-by-step explanation:
Given:
Cost of each banana = $0.90
Cost of each mango = $2
Total amount = $25
Find:
Inequality
Computation:
Assume;
Number of banana = b
Number of mango = m
Total amount ≥ Cost of total banana + Cost of total mango
25 ≥ 0.90b + 2m
Answer:
Simplifying
5w = 9
Solving
5w = 9
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Divide each side by '5'.
w = 1.8
Simplifying
w = 1.8
Answer:
O x = - 6 or x = 2
Step-by-step explanation:
x² + 4x - 4 - 8 = 0
x² + 4x - 12 = 0
x² + 6x - 2x - 12 = 0
x(x + 6)x - 2(x + 6) = 0
(x + 6) (x - 2) = 0
x + 6 = 0 or x - 2 = 0
x = - 6 or x = 2
Thus, x = - 6 or x = 2

Answer:
The greatest number of adults who could have purchased tickets is 105.
Step-by-step explanation:
<em>Let the number of amount of adult tickets sold out be x</em>
Therefore ,
the number of amount of child tickets sold out be 3 × x
Total amount earned = 7 × x + 4 × 3 × x
= 19 × x
According to the question ,
19 × x ≤ 2000
⇒ x ≤ 105
Hence,
The greatest number of adults who could have purchased tickets is 105.
