Answer:
Step-by-step explanation:
Lets call the calories in one cup 'x'
so (3/4)x=90
Solving for x:
x=(90)/(3/4)
x=120
Now for 4 cups:
(4)(120)=?
480 calories in 4 cups of cereal
Answer:
83 - x = 72
x= 11 (if you need it)
Step-by-step explanation:
You wanted an expression, correct?
Answer:
The ratio of the circumference of a circle to the diameter of that circle is the value pi (22/7)
Step-by-step explanation:
Mathematically,
the circumference of a circle is by the formula;
C = 2 * pi * r
Now, as we know, 2r is d where r is the radius of the circle and d is the diameter of the circle
that means;
C = pi * d
hence;
C/d = pi
So the ratio of the circumference of any circle to the diameter is the value called pi

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>to find:</h3>
<h3>tips and formulas:</h3>
- to find x and y intercept we have to substitute x and y to 0
<h3>let's solve:</h3>
let's substitute x to 0 to find y intercept
therefore y intercept is 0
let's substitute y to 0 to find x intercept
- 0=(-¼)x+2
- (-¼)x=-2
- x=-2×-4
- x=8
therefore
<h3>x intercept is 8</h3>
and
<h3>y intercept is 2</h3>
also see the graph
explanation of the graph
you can clearly see that the red line crosses x and y axis to (8,0) and (0,2) respectively
therefore
x intercept is 8
and
y intercept is 2
X + y = 10
y = x + 2
so sub in x + 2 for y back into the first equation
x + y = 10
x + x + 2 = 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 8/2
x = 4
y = x + 2
y = 4 + 2
y = 6
solution is : (4,6)
