Answer: p x (3q - 5 - 2pq)
Answer:
1.85%
Step-by-step explanation:
→ Find the difference between the actual and predicted
5.5 - 5.4 = 0.1
→ Divide answer by 5.4
0.1 ÷ 5.4 = 0.01851851851
→ Multiply answer by 100
0.01851851851 × 100 = 1.85%
The first question:
'is' in mathematics means equal
'of' in mathematics means multiplication
56% of 25 is 14.
And the second question:
'is' in mathematics means equal
'of' in mathematics means multiplication
55% of 20 is 11<span>.</span>
8x - 9y = 11
Subtract 8x to both sides:
-9y = -8x + 11
Divide -9 to both sides:
y = 8/9x - 11/9
or
y = 8/9x - 1 2/9
