Answer:

y = 0.3

Step-by-step explanation:

Solve for y:

[tex] \longrightarrow [/tex] (3.2y - 1.8) - (5.2 y + 3.4) = -5.8

-(5.2y + 3.4) = -5.2y - 3.4:

[tex] \longrightarrow [/tex]3.2y - 1.8 -5.2y - 3.4 = -5.8

Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):

[tex] \longrightarrow [/tex] (3.2y - 5.2y) + (-1.8 - 3.4) = -5.8

3.2y - 5.2y = -2 y:

[tex] \longrightarrow [/tex] -2y + (-1.8 - 3.4) = -5.8

-1.8 - 3.4 = -5.2:

[tex] \longrightarrow [/tex] -5.2 - 2y = -5.8

Add 5.2` to both sides:

[tex] \longrightarrow [/tex] (5.2 - 5.2) - 2y = 5.2 - 5.8

5.2 - 5.2 = 0:

[tex] \longrightarrow [/tex] -2y = 5.2 - 5.8

5.2 - 5.8 = -0.6:

[tex] \longrightarrow [/tex] -2y = -0.6

Divide both sides of -2y = -0.6 by -2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2} [/tex]

[tex] \sf \dfrac{-2}{-2} = 1: [/tex]

[tex] \longrightarrow [/tex] [tex] \sf y = \dfrac{-0.6}{-2} [/tex]

[tex] \sf \dfrac{-0.6}{-2} = 0.3: [/tex]

[tex] \longrightarrow [/tex] y = 0.3

Answer:

1. D (5 fruit baskets)

2. C (4)

3. B (-10)

Step-by-step explanation:

1.  Subtract 30 from 105 to get 75, as this is how much she paid for the annual membership fee. Then divide 75 by 15, this being the cost of the fruit baskets. Your answer would be 5, because 75/5=15.

2. Subtract 5 from 21. This would give you 16. Now you need to find out which number you would need to equal that 16. So 4x?=16. The answer would be 4.

3. Figure out what 5x? would need to be to get to -50. This would be -10, as -10x5=-50. Then just add in the 2, and since you're adding the positive 2 to a negative number, the negative number would be closer to 0, so -48.

i just multiply the 0.31 by the number of days in September to get the average  

Answer:

Average rate of change from day 2 to day 5 is $43.33/day.

Step-by-step explanation:

Sales on day 2 = 200

Sales on day 5 = 330

Rate of change = [tex]\frac{330-200}{5-2} =\frac{130}{3}=43.33[/tex]

Answer:

Approximately 15 tea hees

Step-by-step explanation:

Given that:

Number of teachers needed to Mark 500 exam papers in 30 hours =

Hence, marking rate of each teachers ;

500 / (30 * 10) = 500 / 300 = 1.667 papers per hour

If teachers mark at this rate, the number of teachers which will be required to mark 600 exam papers in 25 hours ;

Let number of teachers = t

(Rate * number of hours * number of teachers) = number of exam papers to be marked

(1.6667 * 25 * t) = 600

41.666665t = 600

t = 600 / 41.666665

t = 14.40000

Number of teachers needed = about 15 teachers

Answers:

Larger bottle = 44 gallons

Smaller bottle = 33 gallons

=====================================================

Explanation:

L = capacity of larger bottle

S = capacity of smaller bottle

Capacities are in gallons

We're told the ratio of these capacities is 4 to 3, meaning L/S = 4/3. Note how L goes first on top since 4 is the first number and it's larger than 3.

Cross multiply to get 3L = 4S. We can solve for S to get S = 3L/4.

----------------------------

We're also told that the larger bottle has 11 more gallons than the smaller one, so,

Larger = Smaller + 11

L = S+11

L = (3L/4) + 11 .... plug in S = 3L/4

4L = 4*(3L/4) + 4*11 ... multiply every term by 4

4L = 3L + 44 .... the fraction goes away afterward

4L-3L = 44 .... subtract 3L from both sides

L = 44

The larger bottle can hold 44 gallons

S = 3L/4

S = 3*44/4

S = 3*11

S = 33

The smaller bottle can hold 33 gallons

Note that L-S = 44-33 = 11 to show there's an 11 gallon difference between the larger and smaller bottles. We can also see that L/S = 4/3 is also true because 44/33 = 4/3. This confirms our answers.

Answer:

7.5+7.5=15

4.5+4.5=9

Answer:

11 a.m

Step-by-step explanation:

Answer: 1 : 3

Step-by-step explanation:

¹/₄ of the tiles are white. To find the ratio, assume the tiles are 4 in number.

If there are 4 tiles;

White = ¹/₄ * 4 = 1 white tile

Grey tiles = 4 - 1 = 3 grey tiles

The ratio is therefore;

1 white tile : 3 grey tiles

1 : 3
