What is 30% of x is 60

Answers

Answer 1

Answer: 30% × = 60

30% = $(30)/(`00)$ = 0.3

0.3x = 60

Divide by 0.3 on either sides to isolate x

$(0.3x)/(0.3)$ = $(60)/(0.3)$
x = 200

30% of 200 is 60

Answers

The slope is 2/3
The y-intercept is 5
so y = 2/3x + 5

How to graphically solve this system of equations?

In order to graphically determine the solution for this system of linear equations on a coordinate plane, we would make use of an online graphing calculator to plot the given system of linear equations while taking note of the point of intersection;

y=x+2 ......equation 1.

y=2x-1 ......equation 2.

Part a.

Based on the graph shown, we can logically deduce that the solution for this system is represented by the ordered pair (3, 5) in quadrant I.

Part b.

By using the substitution method to substitute for y, we would set the two equations equal to one another;

x + 2 = 2x - 1

2x - x = 1 + 2

x = 3

y = x + 2

y = 3 + 2

y = 5.
