Answer:

40.6 inches

Step-by-step explanation:

The plant's initial height is 7 inches tall.

It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:

1.3 * 27 = 35.1 inches

It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:

7 + 35.1 = 42.1 inches

The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:

0.5 * 3 = 1.5 inches

Therefore, after 30 days, the plant's new height is:

42.1 - 1.5 = 40.6 inches

The plant's height after 30 days is 40.6 inches

Find the area of the rectangle below multiplying its length and width (5x-4)(2x-5)

Serhud [2]

Use the FOIL method to multiply these terms. Multiply the first, outside, inside, and last terms:

(5x - 4)(2x - 5)

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

10x² - 25x - 8x + 20

10x² - 33x + 20

The area of the rectangle should be 10x² - 33x + 20.

I need help with number 8,please.

kodGreya [7K]

Let x be equal to the number of drinks Yasmine consumed.
Jose had 2 times that drink so his number of consumed drink would be represented by 2x.
Sally had 3 fewer drink than Jose so her number of consumed drinks would be represented by 2x-3.
Altogether, the three of them consumed 72 drinks so your equation would be:
x+2x+(2x-3)=72
add like terms together:
5x-3=72
have the term with x be alone on one side of the equation, in this case by adding three to both sides:
5x=75
now divide both sides by five for the value of x and your answer is.....
x=15

Answer:

Second choice:

$x=2t$

$y=4t^2+4t-3$

Fifth choice:

$x=t+1$

$y=t^2+4t$

Step-by-step explanation:

Let's look at choice 1.

$x=t+1$

$y=t^2+2t$

I'm going to subtract 1 on both sides for the first equation giving me $x-1=t$ . I will replace the $t$ in the second equation with this substitution from equation 1.
