Answer:

1. 44 + 3x

2. 2y - 8

3. x - 6

15. 5\frac{7}{8}

16. 6\frac{1}{3}

17. 3\frac{7}{9}

Step-by-step explanation:

1. 7² + 2² - 5 - 4 + 3x

   49 + 4 - 5 - 4 + 3x

       53 - 5 - 4 + 3x

           48 - 4 + 3x

              44 + 3x

2. - y - 5 + y + 2(2y-y) - 3

     -y - 5 + y + 4y - 2y -3

      -y - 5 + 5y - 2y - 3

          4y - 2y - 5 - 3

                2y - 8

3. 5x -3 - x - 3(x + 1²)

    5x - 3 - x - 3x - 3

      4x - 3x - 3 -3

           x - 3 -3

             x - 6

15.  7\frac{1}{4} - 1\frac{3}{8}

   = 7 \frac{2}{8} - 1\frac{3}{8}

   = \frac{58}{8} - \frac{11}{8}

   = \frac{47}{8} → 5\frac{7}{8}

16.  9 - 2\frac{2}{3}

   = \frac{54}{6} - 2\frac{4}{6}

   = \frac{54}{6} - \frac{16}{6}

   = \frac{38}{6} → 6\frac{2}{6} → 6\frac{1}{3}

17.  10\frac{1}{3}  - 6\frac{5}{9}

   =  10 \frac{3}{9} - 6\frac{5}{9}

   =    \frac{93}{9} - \frac{59}{9}

   =     \frac{34}{9} → 3\frac{7}{9}

Hope this helps.

A 2-liter bottle of juice costs $2.80. A box containing six 12-liter bottles sells for $3.90. Which option has a higher cost per
barxatty [35]

Answer:The first option has a higher cost per liter and the required cost is $1.40 per liter.

Step-by-step explanation:

Step-by-step explanation:  Given that a 2 liter bottle of juice cost $2.80. A box containing six 12 liter bottle sells for $3.90.

We are to select the option that has a higher cost per liter.

We will be using the UNITARY method to solve the given problem.

Option (1) :  

The cost of 2 liter bottle of juice = $2.80.

So, the cost of 1 liter bottle of juice will be

Option (2) :  

The cost of six 12 liters bottle of juice = $3.90.

So, the cost of 1 liter bottle of juice will be

Since 0.05>1.40, so the option of 2 liter bottle costing $2.80 has a higher cost per liter.

And, the required cost is $1.40 per liter.

Sandra throws an object straight up into the air with an initial velocity of 38 ft/s from a platform that is 30 ft above the gro
Makovka662 [10]

Answer:

The answer is C.

Step-by-step explanation:

Given formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height.

In this case, the initial postion is a platform 30ft above ground so h0=+30

The initial velocity is 38 ft/s straight up into the air so v0=+38

h(t)=-16t2+38t+30

When the object hits the ground, h=0.

h=-16t2+38t+30=0

Simplifying 8t2-19t-15=0

(8t+5)(t-3)=0

t=-5/8 or 3

As time cannot be -ve, t=3s. The answer is C.
