Answer:
Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5
Subtract x from both sides
Divide both sides by 3
The slope of the line is the coefficient of x
Slope =
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of
Having calculated the slope, next is to calculate the equation of the line using the following formula;
Where m is the slope; m = ;
Substitute these values in the formula above; the formula becomes
Cross Multiply
Open brackets
Add x to both sides
Add 6 to both sides
Multipby both sides by -3
Comparing the above to Ax + By = 3
The students should buy 144 packages of 12 wieners and 8 buns.
The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
We have been given that the grade 7 students expect to sell between 100 and 150 hot dogs.
We have to determine the common multiple between 100 and 150
Here are multiples of 8:
8,16,24,32,40,.... , 136, 144
Here are multiples of 12:
12,24,36,48....., 132, 144
The highest common factor is 144 which is lower than 150 hotdogs, so it is 144.
Therefore, the students should buy 144 packages of 12 wieners and 8 buns.

40% = .4 because % means hundredths. So 40% = 40/100 = .4
Let x be the total number of marbles.
Then, .4x = 24
Divide both sides by .4
x = 60 and 24 is 40% of 60 marbles

Answer:
$201
Step-by-step explanation:
Showing two methods:
Method 1:
6.25 percent of $189 is 189·6.25/100 = 11.8
$198 + $11.8 = $200.8 ≈ $201
Method 2:
You can multiply with 1 plus the percentage to get the total amount in one go. So you multply with 1 + 6.25/100 = 1.0625
$189 · 1.0625 ≈ 201
