Sierra says that she can simplify the side of the inequality shown by combining the terms within the parentheses but that she c

stiv31 [10]

Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

$4(y + 7) > -3 (4 + 5)$

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: $4 + 5 = 9$

So, we have:

$4(y + 7) > -3 (4 + 5)$

$4(y + 7) > -3 *9$

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>

the germination rate for zinnia seeds is 78%. this means that 78 out of every 100 seeds will sprout and grow. if james wants 60

Harlamova29_29 [7]

Answer: 77 seeds

Step-by-step explanation:

Given: The germination rate for zinnia seeds =78%

Let x be the total number of seeds he planted, then

The seeds germinated= 78% of x

⇒The seeds germinated= 0.78x

If James wants 60 zinnia plants for his yard, then it will give the equation

$0.78x=60\\\Rightarrow\ x=\frac{60}{0.78}\\\Rightarrow\frac{6000}{78}\\\Rightarrow\ x=76.92307\aprrox77$

Hence, he should plant 77 seeds .
