Mathematics
1 answer:
ella [17]2 years ago
4 0

Answer:

a) $420 b) $399

Step-by-step explanation:

a) $600 = 100%

$60 = 10%

$60 times 3 gives 30% = $180

$600 - $180 = $420

b) $420 = 100%

$42 = 10%

$21 = 5%

this means, they profitted by $21.

so $420 - $21 = $399

therefore, $399 is the cost price

Math is a joke, help plz
gtnhenbr [62]

Answer:

Each piece would be 1.8 yards, or in fraction form, 1 \frac{4}{5}.

Step-by-step explanation:

Just turn 14 2/5 into a decimal, which is 14.4. Then, divide it by 8 using a calculator, and 14.4/8 equals 1.8. In fraction form, this is 1 \frac{4}{5}.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck with your assignment. :)

Write three different equations that have x=5 as a solution
svlad2 [7]

Answer: The three different equations will be

x+3=8\\\\2x-8=2\\\\4x-4=16

Step-by-step explanation:

We have to write three equation that have x = 5 as a solution:

1) First equation will be

x+3=8\\\\x=8-3\\\\x=5

2) Second equation will be

2x-8=2\\\\2x=8+2\\\\2x=10\\\\x=\frac{10}{2}\\\\x=5

3) Third equation will be

4x-4=16\\\\4x=16+4\\\\4x=20\\\\x=\frac{20}{4}\\\\x=5

Hence, the three different equations will be

x+3=8\\\\2x-8=2\\\\4x-4=16

Use the substitution method to determine the solution of the system of equations. y = -5x and 21x - 7y = 28
8_murik_8 [283]

Answer:

x = 1/2   y = -5/2

Step-by-step explanation:

Since we already know an equation for y, we just need to plug it into the other equation.

21x - 7(-5x) = 28

21x + 35x = 28

56x = 28

x = 1/2

Now that we know x, we substitute it into the other equation, to find y.

y = -5x

y = -5(1/2)

= -5/2
