5 wholes = 5
2 fifths = 2/5
5 - 2/5 = 4 3/5 (4 and 3 fifths)
Answer = 4 3/5
Check work:
4 3/5 + 2/5 = 5 (wholes)
Answer:
275
Step-by-step explanation:
180-130=50
25*9=225
225+50 = 275
{ 3-y=2x
{ x+1/2y=3/2
{ -y=2x-3
{ 1/2y=3/2-x
{ y=-2x+3
{ y=3-2x
-2x+3=3-2x
(x,y) = (x,-2x+3)
Answer:
y = 3 * x
Step-by-step explanation:
We have the function y = 5 * x, they ask us what would happen if we change the 5 by the 3. thus:
y = 3 * x
the constant that accompanies x in this case is an increase or slope constant, that is, now x will not increase by a ratio of 5, but by a ratio of 3. For example:
If x were worth 10
the value before was 50 and now it will be 30.
I do not increase 5 times but 3 times.
Answer:
Let
x = number of yards mowed
The domain of the function is
5 ≤ x ≤ 20
If we multiply the inequality by 25, we get
125 ≤ 25*x ≤ 500
Which is the same as
125 ≤ f(x) ≤ 500
(Range of the function)
Domain 5 ≤ x ≤ 20
Range 125 ≤ f(x) ≤ 500
