So you solve (4*4-31) first which is -15 and this equation now is 1-5+1*-15*8, and the answer is going to be -124

Serena estimates that she can paint 60 square feet of wall space every half-hour. Write an equation for the relationship with ti

Katarina [22]

Answer:

So, the relationship with i hours as the indecent variables would be

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint =

In i hours, she can paint =

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

Now, Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

5. What is the probability that a number picked from the set {-4,-3,-2,-1,0,1,2,3,4,5) will be a

tatiyna

Answer:

70%.

Step-by-step explanation:

Rearrange the inequality to isolate $x$ . Start by subtracting $5$ from both sides of the inequality:

$2\,x + 5 - 5 > 1 - 5$ ,

$2\, x > -4$ .

Divide both sides by $2$ . (Keep in mind that if the multiplier or divisor is smaller than zero, it will flip the inequality sign.)

$x > -2$ .

There are ten numbers in this set. Only seven of them will satisfy this inequality. Note that the " $>$ " symbol means strictly greater than (while " $\ge$ " means greater than or equal to.) As a result, $x = -2$ will not count as a solution.

Assume that the number is picked randomly.

$\begin{aligned}&\text{Probability of Success} \cr = & \dfrac{\text{Number of Choices that lead to Success}}{\text{Number of all Choices}} \cr =& \dfrac{7}{10} \cr = &0.7 \cr =& 70\% \end{aligned}$ .

Please help me<br> thanks!!

Answer:

Step-by-step explanation:

Question One

Multiply through by 2

2*1/2 * (2x + y ) = 21/2 * 2

Combine

2x + y = 21

Subtract 2x from both sides

y = 21 - 2x

Now equate the two given equations

y = 21 - 2x

y = 2x

Add 2x to both sides

2x = 21 - 2x

2x + 2x = 21

4x = 21

x = 21/4

x = 5 1/4

x = 5.25

Question 2

$\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2}{(x + 2)}$

multiply numerator and denominator of the second fraction by (x + 2)

$\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2(x + 2)}{(x + 2)*(x + 2)}$

Remove the numerator brackets in the right hand fraction. Look out for the minus sign.

$\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2(x + 2)}{(x + 2)^2}\\\\\dfrac{2x + 6- 2x - 4}{(x + 2)^2}}\\\\\dfrac{2}{(x + 2)^2}$
