4. Solve each equation for x. (8 points: 2 points each)
a.) 3x-12y=27
b.) 6x-7y=-2
c.) 4x-k=17
d.) kx+c=9
Answers
Answer:
a. x = 9 + 4y
b. x = (7y-2)/6
c. x = (17 + k)/4
d. x = (9-c)/k
Step-by-step explanation:
In each of the equations, we want to make x the formula subject
a) 3x-12y = 27
3x = 27 + 12y
3x = 3(9 + 4y)
x = 9 + 4y
b) 6x-7y = -2
6x = 7y-2
x = (7y-2)/6
c) 4x - k = 17
4x = 17 + k
x = (17 + k)/4
d) kx + c = 9
kx = 9-c
x = (9-c)/k
The number of students that earn straight A's decreases by half
each year. Currently there are 20 students who have all A's. Write
an equation to represent this scenario.
Answers
Step-by-step explanation:
20 ÷ 2 = S
S represents the students that have straight A's the next year. You would simply divide the current number of students by 2 and it will give you half the student number you had before. And those are the students who still are getting straight A's.

Suzanne bought 50 apples at the orchard. She bought 4 times as many red apples as green apples. How many more red apples than green apples did Suzanne buy?
Answers
Step-by-step explanation:
Let x be the number of Green apples bought.
Then 4x is the number of Red apples bought.
We have x + 4x = 50, so x = 10.
Since there are 10 green and 40 red apples, 40 - 10 = 30 more red apples than green apples.

Peter leaves work and drives 10miles due south he then heads east for 11 miles to reach his home how far is Peter home from where he works round answer to nearest tenths place
Answers
Answer:
14.9 miles
Step-by-step explanation:
In the image below, the side of the triangle a, represents; "Peter leaves work and drives 10miles due south".
The side of the triangle b represents; "he then heads east for 11 miles to reach his home"
The distance between his work and home is represented by side c of the triangle.
This is a tight angle triangle, hence pythagoras theorem would be applied in solving it.
This theorem states that the square of the hypotenuse of a right angle triangle is equal to the sum of the squares of the other two sides;
This means we have;
c² = a² + b²
c² = 10² + 11²
c = √(100+121)
c = 14.87
Rounding off to the nearest tenths = 14.9
