Answer:
5/9 of 90 = (5/9)(90) = 50
Step-by-step explanation:
Answer:
the following studies may fail to yield the desired information because
(a) i. some of the students might have died before 2015.
ii. Some people might lie based on the questionnaire sent.
So based on the two factors above the desired information might be altered or incorrect.
(b) i. individuals may be unwilling to provide accurate answers during the survey.
Step-by-step explanation:
Information may be altered when individuals are asked about their income or spending in other to show off to friends or the person asking the questions.
Answer:
The two linear equation
x + y = 19.... Equation 1
0.55x + 0.75y = 12.65... Equation 2
Nedra purchased
9 Apples and 11 Oranges
Step-by-step explanation:
Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?
Let the number of apples be represented by x
The number of oranges by represented by y.
Hence,
Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,
Hence:
x + y = 19..... Equation 1
x = 19 - y
$0.55 × x + $0.75 × y = $12.65
0.55x + 0.75y = 12.65.....Equation 2
Hence: we substitute 19 - y for x in Equation 2
0.55(19 - y) + 0.75y = 12.65
10.45 - 0.55y + 0.75y = 12.65
-0.55y+ 0.75y = 12.65 - 10.45
0.20y = 2.2
y = 2.2/0.20
y = 11 oranges
x = 19 - y
x = 19 - 11
x = 8 Apples
