1) make q the subject of the formula 4(q+p)=5+7q

2) Make x the subject of the formula y=2a-bx^2

Answers

Answer:

1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]

2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]

Step-by-step explanation:

1) 4(q + p) = 5 + 7q

Multiply 4(q + p):

4q + 4p = 5 + 7q

4p - 5 = 7q - 4q

4p - 5 = 3q

[tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]

[tex]\frac{4p}{3} - \frac{5}{3} = q[/tex] or [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]

Leila puts an integer into the "In" box of each machine.
She finds that the answer that appears in the "Out" box of Machine A is the same as the
answer that appears in the "Out" box of Machine B.
What was the answer produced by both machines?
Show how you figured it out

Answers

The machines represent equivalent expressions.

The output produced by both machines is 372

The equation represented on machine A is:

[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]

The equation represented on machine B is:

[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]

Where: x and y represent the inputs and the outputs, respectively

When the outputs are the same, it means:

[tex]\mathbf{y = y}[/tex]

So, we have:

[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]

Open brackets

[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]

[tex]\mathbf{10x - 18 = 8x + 60}[/tex]

Collect like terms

[tex]\mathbf{10x - 8x = 18 + 60}[/tex]

[tex]\mathbf{2x = 78 }[/tex]

Divide both sides by 2

[tex]\mathbf{x = 39 }[/tex]

Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]

[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]

[tex]\mathbf{y = 372}[/tex]

Hence, the output produced by both machines is 372

Hi I’m suppose to write an equation and solve for it. I can’t figure out what I’m doing, it’s a straight angle. Thank you if you figure this out!

Answers

Answer:

Equation: 4x+28= 180

x= 38

Step-by-step explanation:

To solve, you should start by trying to find "x". To do this you can use the expression "4x+28= 180"

TO solve 4x+28= 180, first subtract 28 from both sides:

4x= 152

Then divide by 4;

x= 38

Check your work:

M<1= 38+10 -------> 48

M<2= 114+18 -------> 132

132+48= 180

Answers

Answer:

increase

Step-by-step explanation:

the change from 32 miles to 24 is decrease is 8 difference. % change to 196 is an increase.

The percentage change is 25% and it is a percent of increase.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To find the percentage change from 32 miles to 24 miles, we first need to calculate the absolute change:

Absolute change = Old value - New value

Absolute change = 32 miles - 24miles

Absolute change = 8 miles

Percentage change = (Absolute change / Old value) x 100%

Percentage change = (8 miles / 32 miles) x 100%

Percentage change = 25%

Which means there is a 25% increase from 32 miles to 24 miles.

Therefore, the percentage change is 25% and it is a percent of increase.

A train leaves Zurich at 2240 and arrives in Vienna at 07 32 the next day. Work out the time taken.
The answer is 8 hours 32 minutes
But can someone properly explain how

Answers

Step-by-step explanation:

Okay so, 22:40 is 10:40pm

07:32 is am

Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)

Then there would be 8 hours alone (11 to 7 is 8 hours)

So it takes 8 hours and 52 minutes from 10:40pm to 7:32am

$500 just divide by 4 because 25/100 = 1/4

Answer:

$500

Step-by-step explanation:

Simply change the 25% into a decimal which is 0.25 and multiply $2000.

Or you can change 25% into a a fraction which is 25/100 and simplify giving 1/4. Then simply multiply $2000 by the fraction: 2000/1×1/4. Cross multiply which is 2000×1/1×4=2000/4. Now simply divide 2000 by 4 and you get 500 as your answer.
