  5x+1y=13.75

Answer:

1 pound of apple costs $2.50

1 pound of strawberries costs $1.25

Step-by-step explanation:

System of Equations

Let's define the following variables:

x = cost of 1 pound of apples

y = cost of 1 pound of strawberries

.........................................

Marcus purchased 3 pounds of apples and 4 pounds of strawberries for a total of $12.50. Thus:

3x + 4y = 12.50       [1]

Shannon purchased 5 pounds of apples and 1 pound of strawberries for a total of $13.75, thus:

5x + y = 13.75       [2]

We need to solve the system of the equations [1] and [2].

Solving for y in [2]:

y = 13.75 - 5x       [3]

Substituting in [1]

3x + 4(13.75 - 5x) = 12.50

Operating:

3x + 55 - 20x = 12.50

-17x = -55 + 12.50 = -42.50

Dividing by -17:

x = -42.50/(-17)

x = 2.5

Substituting in [3]:

y = 13.75 - 5*2.5

y = 1.25

Solution:

1 pound of apple costs $2.50

1 pound of strawberries costs $1.25

Answer:

100

Step-by-step explanation:

here we are solving for x

first plug in 100 for the ys in the equation

0.10x + 0.10(100) = 0.18(x + 100)

simplify

0.10x + 10 = 0.18x + 18

get x by itself

-8 = 0.08x

-100 = x

so the reasonable answer here would be 100

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed=[tex]\frac{Distance}{time}[/tex]

Using proportion

[tex]\frac{a}{b}=\frac{c}{d}[/tex]

[tex]\frac{135}{3}=\frac{36}{x}[/tex]

[tex]x=\frac{360\times 3}{135}[/tex]

[tex]x=8[/tex]

Hence, the time taken by Casi to drive 360 miles=8 hours

Answer:

x=3.11

Step-by-step explanation:

Sin 15 degrees = x/12

multiply 12 on both sides to get rid of the denominator

now you have 12 times the sin of 15 degrees = x

which can also be written as 12 sin 15 = x

put 12 sin 15 into your calculator and you get 3.105828541 or just 3.11 when rounded to the nearest hundreth

Answer:  [tex]\frac{n}{3}[/tex] which is the same as writing n/3

The slash is used as a division sign and also as a fraction sign, since the two ideas are very closely connected. The quotient is the result of dividing two numbers.

Answer:

Step-by-step explanation:

4c + 18 = 74​         {subtract 18 from both sides}

4c = 56               {divide both sides by number by x (4)}

 c = 14

[tex]\boxed{\boxed{\pink{\bf\leadsto The \ domain \ of \ x \ will \ be \ (-\infty , +\infty) \ that \ is\ all \ real .}}}[/tex]

Firstly set the argument in which (x² + 3) is Greater than 0 , to see where the expression is defined .

[tex]\bf \implies (x^2+3) > 0 [/tex]

Now ,let's simplify this

[tex]\bf \implies (x^2+3)>0 \\\\\bf\implies x^2 > 0 - 3 \\\\\bf\implies\boxed{\red{\bf x^2 > (-3) }}[/tex]

Since the left side has even Power , it is always positive for all real numbers.

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Answer:

7680 rabbits

Step-by-step explanation:

Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:

[tex]y=ab^x[/tex]

Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:

[tex]y=26(2^{(\frac{x}{30} )})\\\\for\ 240\ days, i.e\ x=240:\\\\y=26(2^\frac{240}{30} )\\\\y=7680\ rabbits[/tex]

Answer:

1 5/24

Step-by-step explanation:

5/6 + 3/8

LCM of 6&8=24

(5/6)*4 =20/24

(3/8)*3=9/24

20+9/24= 29/24

QRD(Quotuient,Reminder,Divisor)

= 1 5/24

B.

Answer:

The second option, 1 5/24

Step-by-step explanation:

First off, find da flipping LCD UnU

6: 6, 12, 18, 24, 30

8: 8, 16, 24, 32, 40

We find that it is 24 UwU

5 x 4 = 20

6 x 4 = 24

5/6 - > 20/24

3 x 3 = 9

8 x 3 = 24

3/8 - > 9/24

20/24 + 9/24 = 29/24

29 - 24 = 5

29 ÷ 29 = 1

1 5/24

Answer:
