What is the solution set? Enter your answer in the box

Xelga [282]

Answer:

$x>3$

The solution set is $(3, infinite)$

Step-by-step explanation:

we have

$5.5x+15.5>32$

Solve for x

Subtract $15.5$ both sides

$5.5x+15.5-15.5>32-15.5$

$5.5x>16.5$

Divide by $5.5$ both sides

$5.5x/5.5>16.5/5.5$

$x>3$

The solution is the interval-------> $(3, infinite)$

All real numbers greater than $3$

Combine like terms to find the equivalent expression to6(58u+1)−6(−74u−5).

gtnhenbr [62]

Answer:

-36 • (22u + 1)

Step-by-step explanation:

Pulling out like terms :

2.1 Pull out like factors :

-74u - 5 = -1 • (74u + 5)

Equation at the end of step 2 :

(6 • (58u + 1)) - -6 • (74u + 5)

Step 3 :

Equation at the end of step 3 :

6 • (58u + 1) - -6 • (74u + 5)

Step 4 :

Pulling out like terms :

4.1 Pull out 6

Note that -6 =(-1)• 6

After pulling out, we are left with :

6 • ( (-1) * (58u+1) +( (-1) * (74u+5) ))

Step 5 :

Pulling out like terms :

5.1 Pull out like factors :

-132u - 6 = -6 • (22u + 1)

Final result :

-36 • (22u + 1)
