Answer:
Word problem: A recipe for making cookies use half cup of sugar for 1 cup of flour to make one pound of cookies. How many cups of sugar you need to make 3 pound of cookies.
As you can see to solve that problem you need to multiply the fraction 1/2, which is the number of cups needed to make 1 pound of cookies, times the number of pounds that you want to make.
So, for this problem you have to multiply 1/2 times 3.
My estimate is that the result is 1.5.
You can verify my estimate by multiplying:
1 3x1 3
3 x ----- = ------ = ------ = 1.5
2. 1x2 2
So, I have shown that my estimate was correct.
Answer:
y - 2 = 3(x - 2)
Step-by-step explanation:
Hello!
Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.
(2,2) is one point on the line, and the slope is m = -3.
Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).
5x - 9 ≤ 21
5x ≤ 21 + 9
5x ≤ 30
x ≤ 30 ÷ 5
x ≤ 6
Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100
