Please help me solve this: y=8x 4x+y=48

Answers

Answer: x=4, y=32

Step-by-step explanation:

y=8x

4x+y=48

Plug in 8x for y in the equation

4x+8x = 48

Add like terms

12x= 48

Divide both side by 12

12x/12=48/12

x= 4

Then plug 4 back into the original equation in place of x

4(4)+y=48

16+y=48

Minus 16 from both sides

y= 48-16

y= 32

Answer: (4,32)

Answer: x = 4

Step-by-step explanation: 48 divided by 12 = 4

4 x 4 = 16

Y = 8x

8 x 4 = 32

32 + 16 = 48

y=-1/2x+5 slope=-1/2 because it goes down one unit and to the right 2 units, and the y intercept is 5 because that's where the line intercepts the y-axis!
y= -1/2+5x because since the line is facing that certain way it will be negative and the line goes through the y axis at 5

A family gathered 20 small seashells from the beach bringing the total number of small seashells in their collection to 41.

Which equation can be used to find, x, the number of small seashells in the collection before the 20 were added?

A store is making 720 limited edition watches available for sale throughout the month. Each day, 6.25% of these watches will be made available for sale.

How many watches will have been made available for sale after 5 days?

Answers

225 watches, multiply 720 by 0.0625 to get per day, then multiply by 5 for 5 days
First fine 5% of 720 which is 36
Then find 1% of 720 which is 7
Then 0.25% of 720 which is 0.75
Now add them together to find 6.25% which is equivalent to 43.75
Now times this by 5 for the 5 days
43.75 x 5 = 218.75
Now rounded up too 219 watches for sale after 5 days

A recipe calls for 12 lb of flour for 1 batch. How many batches can be made with each of the following amounts?

1 lb
[ Select ]
34 lb
[ Select ]
14 lb
[ Select ]

Answers

It could be wrong but I'm pretty sure I'm right.

For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

To find these answers take your amount of flour and divide it by the 12 pounds of flour.

Example; 34 divided by 12 = 2.833

Example 2; 14 divided by 12 = 1.66

Answer:For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

In a particularly sunny month, Solaire's solar panels generated 110%, percent as much power as expected.
What fraction of the expected amount of power did Solaire's solar panels generate?

Answers

Answer:

I think the answer would be 11/10

Step-by-step explanation:

when simplifying a percent into a fraction you always make the denominator 100, since the percent is 110, the numerator is 110, so 110/100. From there you can take off the 0s from the ends of both and boom, 11/10, hope this makes sense!

Answer:

11/10 or 1 1/10

Step-by-step explanation:

110%/100% is equal to 11/10, or 1 1/10

the percent equivalent to Fraction 1 Over 40 Fraction.

Answer:

2.5%

Step-by-step explanation:

The fraction in question is 1/40, or 0.025.  The percent equivalent is found by multiplying this result by 100%:

2) Then Solve the equation for find the value of X. (Make sure to explain or show all the steps to get full Credit)

Answers

I don’t know how I should find the missing angles. But I can solve for X. So first we need to combine like terms so we add 2x, x and x which gives us 4x. And we set up our problem like this: 4x + 24=180. So we then subtract 24 from 180 and get 156 then divide 4x and 156, which leaves us with x=39
