The two ys must be the same. Equate the two right hand sides.

-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4

Now solve for y
y = x + 2
y = 4 + 2
y = 6

Use the other equation to check it.

y = - x + 10
y = -4 + 10
y = 6

Margaret [11]

Answer:

8 bracelets

Step-by-step explanation:

Given

Yellow = 40 beads

Red = 64 beads

Required

Highest number of bracelets

To answer this question, we simply need to determine the highest common factor of the given parameters.

40 = 2³ * 5

64 = 2⁶

HCF = 2³

HCF = 2 * 2 * 2

HCF = 8

Hence, the maximum number of bracelets is 8

Please help I don't understand!
Citrus2011 [14]

Answer:

48

Step-by-step explanation:

Here, the sides are in proportion.

⇒ \frac{24}{k} = \frac{32}{64}

⇒ \frac{24}{k} = \frac{1}{2}

⇒ k = 24 × 2

⇒ k = 48

Austin has two Marvel posters he wants to hang on the wall in his bedroom. The wall is 16.5 feet wide and each poster is 5 3/4 f
vekshin1

The expression for the distance is w=5/3 ft

Step-by-step explanation:

The wall has a width of 16.5 feet

A single poster has a width of 5 3/4 ft which is equal to 23/4 ft or 5.75 ft

For the two posters, the width occupied is ; 23/4 * 2 = 23/2 = 11.5 ft

Remaining width that will be unoccupied by the posters will be 16.5-11.5=5

A sketch of the wall with the two posters such that the edge of the wall is the same as the distance between the posters will show three un-covered spaces, from edge of wall to the first poster, then between the two posters, and lastly from the second poster to the other edge of the wall.

The un-covered 3 portions have an equal width, lets assume that they have a width of w ft

This means 3w will represent the uncovered width which equals to the unoccupied space of 5 ft

Form equation for the uncovered width as;

3w=5ft

w=5/3 ft ---------the distance from the edge of each poster to the nearest edge of wall.

A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% sol
solmaris [256]

Answer:

  A=300ml

Step-by-step explanation:

From the question we are told that

5% solution of dextrose sugar in water

20% solution of dextrose in

100 milliliters of distilled water water

Generally in mathematically solving we call A the amount of D20W added

Since 20% of dextrose is needed

       20 \%*100=20milliter

Total quantity after addition (100+x)

for DW5% total solution is

          5\% (100+A)= \frac{5}{100}(100+A)

          5\% (100+A) =5+0.05A

Mathematically

           5+0.05A =20

           5+0.05A =20-5

           A=\frac{15}{0.05}

           A=300ml

Therefore the required quantity A=300ml
