15 POINTS!!!! BRAINLIEST FOR THE FIRST ANSWER!!! Solve 3-x/2≤18

Bumek [7]

Answer:

$x\geq -30$

Step-by-step explanation:

Work to isolate x on one side of the inequality:

$3-\frac{x}{2} \leq 18\\3-18\leq \frac{x}{2} \\-15\leq \frac{x}{2}\\-30 \leq x$

Therefore the answer is all x values larger than or equal to -30

$x\geq -30$

20.) Which inequality represents the solution on the graph?*<br><br>

VMariaS [17]

Answer:

Option 2

Step-by-step explanation:

You can see that the graph of the inequality is x <= -3, so you want to find why inequality matches that. Solve each one:

. $3x \geq -9\\x \geq -3$

doesn't match

$-7x\geq 21\\x\leq -3$

Does match, so this is the answer.

Jonathan replaced the original factory tires (P220/65 R 18) on his pickup truck with (P255/60 R 17) tires. Calculate the circumf

svet-max [94.6K]

Answer:

92 inches

Step-by-step explanation:

When a tire's size = P220/65 R 18, it means that:

the rim is 18 inches wide (or 457 millimeters)
the width of the tire is 8.7 inches (or 220 millimeters)
the sidewall of the tire is 5.65 inches (or 144 millimeters)
the 65 shows the relationship between tire width and sidewall (65%)

the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches

the circumference = 2 x π x radius or diameter x π = 29.3 x 3.141592 = 92 inches
