Answer:
Not correct
Step-by-step explanation:
Given:
x² - 6x - 7 = 0
The following equation can be solved correctly by factoring Thus,
x² - x + 7x - 7 = 0
x(x - 1) +7(x - 1) = 0
(x - 1)(x + 7) = 0
(x - 1) = 0
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
Or
(x + 7) = 0
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
Therefore, the solution would be x = 1 or x = -7
Lateena solution is therefore NOT CORRECT because she used a wrong method.
Answer:
The number of students who received the paint=5 students
Step-by-step explanation:
Step 1: Determine amount given to each student
Quantity per student=1/7 gallon per student
Step 2: Determine the total amount of paint Mrs. Jennings had
The total quantity of paint Mrs. Jennings is:
Initial quantity of paint=5/7 gallon
Step 3: Calculate number of students who received the paint
The number of students who received the paint can be expressed as;
Initial quantity of paint=Quantity per student×number of students
where;
Initial quantity of paint=5/7 gallons
Quantity per student=1/7 gallons
number of students=n
replacing;
5/7=(1/7)×n
n=(5/7)×7
n=5
The number of students who received the paint=5 students
Answer:
15
Step-by-step explanation:
The calculator is actually correct because he entered division before addition.
Following the Bodmas rule of
B= Brackets O= Off D= Division M= Multiplication A= Addition S= Substraction
And from the question 56÷6 + 3 x 2, when bodmas is applied here it becomes ; (56÷6) +( 3 x2)
And when brackets is removed , it becomes
9+6 = 15.
