Mr. Smith uses Verizon Wireless as his cell phone carrier. His plan costs $60 a month plus &.15 per text message. For his monthly budget Mr. Smith wants to spend no more than $97.50. Write and solve an inequality that can be used to determine the number of text messages Mr. Smith can send this month.

equation is 15x+60<97.50

answer is 2.5 but if that doesn't make sense. To not to over, the answer would be two.

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.

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.
