Answer:

(a) 9

Step-by-step explanation:

r = 4; t = 2

t³ - r + 20 ÷ r =

= 2³ - 4 + 20 ÷ 2

Order of operations says do the exponent first.

= 2 × 2 × 2 - 4 + 20 ÷ 4

Now do the multiplications and the division.

= 8 - 4 + 5

Do the subtraction.

= 4 + 5

Add.

= 9

Answer:

(a) 9

Step-by-step explanation:

\sf t^3 - r + 20 \div  r

substitute r = 4, t = 2

\sf (2)^3 - 4 + 20 \div 4

simplify

\sf (2)^3 - 4 + 5

cubic of 2 is 8

\sf 8 - 4 + 5

simplify

\sf 9

What is the solution to this inequality: -4(3x-5)<2(3x+4)​
Delicious77 [7]

Answer:

x > 2/3

Step-by-step explanation:

-4(3x - 5) < 2(3x + 4)​

Divide both sides by 2.

-2(3x - 5) < 3x + 4

Distribute on the left side.

-6x + 10 < 3x + 4

Subtract 3x from both sides.

-9x + 10 < 4

Subtract 10 from both sides.

-9x < - 6

Divide both sides by -9. Remember that when you divide both sides of an inequality by a negative number, the inequality sign changes direction.

x > (-6)/(-9)

x > 6/9

x > 2/3
