Answer:

infinite solutions

Step-by-step explanation:

The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:

(15x +12y) -3(5x +4y) = (18) -3(6)

0 = 0 . . . . . simplify (true for all values of x or y)

The system of equations has an infinite number of solutions.

sweet [91]

Let length of bc be x cm
Thus, ab=4x
ab+bc=ac
4x+x=75
5x=75
x=75/5
x=15
Therefore, ab=x=15cm
bc=4x=60cm

Find 2 coordinates on the graph : (0, -20) and (10, 10)

Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3

Slope = 3

y-intercept = (0, - 20)

Equation : y = 3x - 20

Since the right hand side is shaded, the equation is y > 3x - 20.

Ksju [112]

Divide 2/3 by 1/8

= 2/3 * 8

= 16/3

= 5 1/3

So the answer is 6 containers

Answer:

D) 3768 inches

Step-by-step explanation:

Given,

No. of plates = 100

Diameter of each plate = 12inches

So, radius of each plate = 12 / 2 = 6 inches

So, circumference of each plate

$= 2\pi \: r$

= 2 × 3.14 × 6 inches

= 37.68 inches

Hence, circumference of 100 plates = 100 × 37.68 inches

= 3768 inches

Hence, <u>3768 inches</u> of gold trim is required (Ans)
