Answer:
The equation is x + y = 15
Step-by-step explanation:
It is given that,
There are 15 plates and each plate is either 7 or 12 inches diameter.
Let the number of 7 inch plates be x and 12 inch plates be y
<u>To find the equation</u>
Total number of plates = 15
By using the given information, we can write
x + y = 15
Therefore the equation is x + y = 15

Draw graph y=3(x+4)+2 ,ignore the modulus sign first.
Flip the bottom part (below x axis) upwards (above x axis) or in other words, reflect the bottom to the top
Step-by-step explanation:
0.15 as a Fraction in simplest form to convert 0.15 to a fraction and simplify to the lowest form.
Working:
0.15 = 15/100
So the simplest form is :
0.15 = 3/20

Answer:
Step-by-step explanation:
Let x and y represent the weights of the large and small boxes, respectively. The problem statement gives rise to the system of equations ...
x + y = 85 . . . . . combined weight of a large and small box
70x +50y = 5350 . . . . combined weight of 70 large and 50 small boxes
We can subtract 50 times the first equation from the second to find the weight of a large box.
(70x +50y) -50(x +y) = (5350) -50(85)
20x = 1100 . . . . simplify
x = 55 . . . . . . . divide by 20
Using this in the first equation, we can find the weight of a small box.
55 +y = 85
y = 30 . . . . . . . subtract 55
A large box weighs 55 pounds; a small box weighs 30 pounds.
