Answer:
0.75 is it the answer
Step-by-step explanation:
1= 4/4 therefore 2=8/4
8/4 + 1/4 = 9/4
So Steve bought 9/4 of pizza total
Answer:
y = (3/2)x - 12
Step-by-step explanation:
Recall that the general equation for a linear function may be written in slope-intercept form:
y = mx + b
where m = slope and b = y-intercept
In this case, it is given that slope = m = 3/2 and y-intercept = b = -12
substituting these values into the general equation:
y = (3/2)x + (-12)
or
y = (3/2)x - 12
The correct answer from least to greatest is 0.6, 0.602, 0.62, and 0.65.
Answer:
Step-by-step explanation:
xy = 300
x + y = 50 Solve for y
y = 50 - x substitute into xy = 300
x(50 - x) = 300 Remove the brackets.
50x - x^2 = 300 Bring the left to the right.
0 = x^2 - 50x + 300
This is a quadratic. It will have 2 solutions.
a=1
b = - 50
c = 300
Put these into the quadratic equation.
It turns out that x has two values -- both plus
x1 = 42.03
x2 = 6.97
x1 + y1 = 50
42.03 + y = 50
y = 50 - 42.03
y = 7,97
(42.03 , 7.97)
====================
x2 + y2 = 50
6.97 + y2 = 50
y2 = 50 - 6.97
y2 = 43.03
(6.97 , 43.03)
