Answer:
x=2 y=17
Step-by-step explanation:
53/17 17x3 = 51 53-51 3 + 1/ x + 1/y
For this case we can solve the problem by means of the following rule of three:
100 $ --------------> 100%
x -------------------> 250%
From here, we clear the value of x.
We have then:
Rewriting we have:
Answer:
The price of a four star dinner today is $ 250.
Answer:
Step-by-step explanation:
a) Area of white square = side *side = 8 * 8 = 64 sq.mm
Area of 4 white square = 4 * 64 = 256 sq.mm
compound shape
length = 3 cm = 30 mm
Width = 2 cm = 20 mm
Area of compound shape = length *width = 30 * 20 = 600 sq.mm
Area of the shaded part of the compound shape =
Area of compound shape - Area of 4 white square
= 600 - 256
= 344 sq.mm
b) Perimeter of compound shape = 2*(length + width)
= 2*(30 +20)
= 2* 50
= 100 mm
The equation of the line is y = -2/3x - 3.
To find this, we first need to turn the intercepts into ordered pairs.
x intercept: (-4.5, 0)
y intercept: (0, -3)
Now we can use these two points and the slope equation to find slope.
m = (y2 - y1)/(x2 - x1)
m = (0 - -3)/(-4.5 - 0)
m = 3/-4.5
m = -2/3
Now that we have the slope, we can use slope intercept form to find the intercept.
y = mx + b
-3 = 2/3(0) + b
-3 = 0 + b
-3 = b
Which allows us to model the equation as y = -2/3x - 3
Answer:
Bob is paying more for the actual steak
Step-by-step explanation:
we know that
Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)
Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)
so
Bob's cut is 2/3 all meat
Find the unit rate of Bob's cut for all meat
therefore
Bob is paying more for the actual steak
