Answer:

x = 1.2375 or 99/90

Step-by-step explanation:

<u>Step 1:  Distribute</u>

21 + 40(2x - 3)

21 + 80x - 120

<u>Step 2:  Combine like terms</u>

21 + 80x - 120

80x - 99

<u>Step 3:  Solve for x</u>

80x - 99 + 99 = 0 + 99

80x / 80 = 99 / 80

x = 1.2375

Answer:  x = 1.2375 or 99/80

Naomi’s fish Is 40 mm long her guinea pig is 25 cm long how much longer is her guinea pig than her fish
tia_tia [17]
1.) Convert the measurements of Naomi's pets so that the two has the same unit of measurements. I will use cm.
                     1 mm = .01 cm;
Therefore:  40 mm = 4 cm is the length of the fish
2.) Subtract the pets' measurements:
         25 cm - 4 cm = 21 cm
3.) Therefore, Naomi's guinea pig is 21 cm longer than her fish.

Which answer choice is a solution to the inequality 1.5x + 3.75≥5.5
djyliett [7]

Answer:

x \geq \frac{7}{6}

The value of x is greater than or equal to 7/6

Step-by-step explanation:

1.5x + 3.75\geq 5.5

Solve the inequality for x

Subtract 3.75 from both sides

1.5x + 3.75\geq 5.5

1.5x \geq 1.75

Now divide both sides by 1.5

x \geq \frac{1.75}{1.5}

Simplify the fraction by dividing top and bottom by 0.25

x \geq \frac{7}{6}

The value of x is greater than or equal to 7/6
