Answer:

B for the first one and it is correct.

x - 4 = - 7 for the second one and it is correct.

Step-by-step explanation:

Left hand panel

<em><u>2x + 5 >  9</u></em>

2x + 5 >  9            Subtract 5 from both sides.

2x + 5 - 5 > 9 - 5  Collect like terms

2x > 4                   Divide by 2

x > 4/2

x > 2

Right Hand Panel

5x ≤ 30     Divide by 5

5x/5 ≤ 30/ 5

x ≤ 6

Your answer is Correct. (B)

Right hand panel

It's not the normal procedure. Usually when you have an absolute value the next step would be

x - 4 = 7 and you add four to both sides. The question is very poorly constructed and it is meant to fool you, but it didn't. You got this one right as well. Both correct.

If you raise 4 to the 214th power, what is the units digit of the result
Len [333]
\begin{array}{lrlll}&#10;4^1&\boxed{4}\\&#10;4^2&1\boxed{6}\\&#10;4^3&6\boxed{4}\\&#10;4^4&25\boxed{6}\\&#10;4^5&102\boxed{4}\\&#10;4^6&409\boxed{6}&#10;\end{array}\impliedby \textit{see the pattern for 4?}

notice, it goes 4,6 then 4, 6 again, and so on and so on
based on whatever exponent it may have

now, you're being asked, what 214 will give? 4 or 6?

.Shanice and Micaela are selling cheesecakes for a school fundraiser. Customers can buy pecan
belka [17]

Answer:

Pecan cheesecake = $11

Strawberry cheesecake= $19

Step-by-step explanation:

To solve this, we will need to set up a system of equations:

Let's call "Pecan cheesecakes" 'x', and

"Strawberry cheesecakes" 'y'.

We can set up the equations once we have our variables:

276= 13x + 7y

295 = 13x +8y

We will need to subtract these equations from each other to get rid of the 'x' variable. This gives us:

295 = 13x+ 8y

        -

276 = 13x+ 7y

19 = y

Therefore, Strawberry cheesecakes cost $19. Plug this into an equation to get the value of 'x':

276= 13x + 7(19)

276 = 13x + 133

143 = 13x

x= $11.

Therefore, Pecan cheesecakes cost $11.
