Steps to solve:

2x - 7 > 3

~Add 7 to both sides

2x > 10

~Divide 2 to both sides

x > 5

Steps to solve:

4 - x <= -4

~Subtract 4 to both sides

-x <= -8

~Divide -1 to both sides

x >= 8

Best of Luck!

Answer:

2x-7>3 -----> x>5

4-x≤-4 ------> x $\geq$ 8

Step-by-step explanation:

2x-7>3

2x-7+7>3+7

2x>10

2x/2 > 10/2

x>5

4-x≤-4

4-x-4 $\leq$ -4-4

-x $\leq$ -8

(-x)(-1) $\geq$ (-8) (-1)

x $\geq$ 8

Simplify using the vertical method. (3k + 4)(3k^2 – 5k – 3)

liubo4ka [24]

Answer:

$9k^{3} -3k^{2}-29k-12$

Step-by-step explanation:

Step 1: Expand by distributing sum groups.

$3k(3k^{2} -5k-3)+4(3k^{2} -5k-3)$

Step 2: Expand by distributing terms.

$9k^{3} -15k^{2} -9k+4(3k^{2} -5k-3)$

Step 3: Expand by distributing terms.

$9k^{3}-15k^{2} -9k+12k^{2} -20k-12$

Step 4: Collect like terms.

$9k^{3}+(-15k^{2} +12k^{2} )+(-9k-20k)-12$

Step 5: Simplify.

$9k^{3} -3k^{2}-29k-12$

Joe is taking part in a run for charity. He has earned $250 in pledges just for running and $40 in pledges for every mile he run

Harlamova29_29 [7]

im in middle school taking algebra 1 rn, but im pretty sure the equation is similar to 40x(40 pledges every mile) + 250(how much he already has from running) = y(the unknown variable).

so the equation would be 40x+250=y and you solve that to get the expression of how much he makes per mile
