Last week end, Mr. Morgan rode his bike 3 miles. This weekend, he rode his bike 21 miles. How many times as many miles did Mr. Morgan ride his bike this weekend as last weekend?

Step-by-step explanation:

Distance rode by Mr Morgan last week = 3 miles

Distance rode by Mr Morgan this week = 21 miles

We need to find how many times as many miles did Mr. Morgan ride his bike this weekend as last weekend.

Distance rode by Mr Morgan this week=k x Distance rode by Mr Morgan last week

21=k x 3

7 times as last weekend.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
