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

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.

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

Answer:
(A) 12:50 pm
Step-by-step explanation:
In the above question, we are asked about that COMMON TIME in which both the bells rings together.
So, in order to find that common time, we will figure out the L.C.M. of 20 and 35.
LCM (20, 35) = 140 minutes, i.e. 2hours and 20 minutes
Now, time after a duration of 2hr and 20 min from 10:30 am =
10:30 + 2:20 = 12:50 pm

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

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

Answer:

x = 20

Step-by-step explanation:

2x + 2x + 10 = 90

4x + 10 = 90

4x = 80

x = 20

Answer:

Angle AOB is made up of angle AOC and COB.

AOC + COB = AOB

Since AOB is a right angle, it is 90°.

Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].

Therefore,

[tex]2x+2x+10=90[/tex]

Subtract 10 from both sides:

[tex]2x+2x+10-10=90-10[/tex]

[tex]2x+2x=80[/tex]

[tex]4x=80[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4} =\frac{80}{4}[/tex]

[tex]x=20[/tex]
