Explain how you can find 3x584 using expanded form

Answers

I believe what you need to do is multiply 3 by each number. 
To start, 3*584 is 1752. Expanded form written out would be (3*500)+(3*80)+(3*4). Simply multiply all the numbers and then add them together. 3*500=1,500; 3*80=240; 3*4=12. 1,500+240=1740+12=1752. Hope this helps! :)

6(3a+1)-30=3(2a-4) okay i suck at algebra . please help me lol

Answers

So expand your brackets so 6(3a+1)=18a+6 now -30 so 18a-24
3(2a-4) becomes 6a-12
18a-24=6a-12
18a-6a=-12+24
12a=12
a=1

The perimeter of a patio is 64. The width of the patio is 12 feet and the length of the patio is (×+6) feet. What is the length of the patio?

Answers

12(2)+(x+6)(2) = 64
 12(2) = 24 
Distribute the (x+6)(2)= 2x + 12
New equation: 
 24 + 2x + 12 = 64
Solve for x, and you will get x = 14 
Then put that back in to (x+6). 14 plus 6 equals 20. Which L = (x+6)

L = 20 
20 is your final answer.

The product of a number m and 1.7 is 6.63. Determine what an equation would be and solve for m. What is the value of m?

Answers

The equation would be m*1.7=6.63, because 6.63 is the *product* (showing that you need to multiply). and to find m you would need to divide 6.63 by 1.7 to do inverse operations. M equal 3.9.

how are rates and ratios related?

Answers

Fundamentally, a ratio is a ratio, a rate is a ratio with time as the denominator and a period is the inverse of a rate.

Of course, there are differential forms of these concepts, where it is not a ratio truly, but it is a “ratio” of differential elements.

26-38+(-3) what is the answer.

Answers

So basically, first just do this step by step, or subtract 38 from 26 first.

26 - 38 is basically -(38 - 26), or -12.

So then, it becomes -12 + (-3)

A - and a + becomes - because you're adding negative 3.

-12 - 3

Which then becomes -15.
The answer to your question is -15

Mrs. Synder must choose two of her homeroom students to be class representatives. The class consists of 13 girls and 9 boys. Approximately what percent chance is there that the first student chosen is a boy and the second student chosen is a girl? (Round to the nearest percent)

A. 10%

B. 25%

C. 22%

D. 15%

Answers

9/22 x 13/21 = 0.25 = 25% B

Answer:   B. 25%

Step-by-step explanation:

Given : Number of boys in the class = 13

Number of girls in the class = 9

Total students  = 13+9=22

Now, the number of ways to choose first boy then a girl =[tex]13\times9=117[/tex]     (1)

Number of ways to choose nay two students :-

[tex]{22}P_{2}=\dfrac{22!}{(22-2)!}\\\\=\dfrac{22\times21\times20!}{20!}=462[/tex]     (2)

Now, the probability that the first student chosen is a boy and the second student chosen is a girl :-

[tex]\dfrac{117}{462}=0.253246753247\approx0.25[/tex]   [Divide (1) by (2)]

In percent , [tex]0.25\times100=25\%[/tex]

Hence, approximately 25% chance that the first student chosen is a boy and the second student chosen is a girl.

There are 300 apples and peaches for sale at a farmer's market. The ratio of the number of apples to the number of peaches is 7 : 8. If 50 apples and 40 peaches are sold, what is the ratio of the remaining apples to peaches?

Answers

7:8.....added = 15

7/15(300) = 2100/15 = 140 apples
8/15(300) = 2400/15 = 160 peaches

if 50 apples and 40 peaches are sold....
apples : 140 - 50 = 90
peaches : 160 - 40 = 120

ratio of remaining is : 90/120 which reduces to 3/4 or 3:4 or 3 to 4 <==

Since he gets 10$ per shirt, his revenue is 10y if y represents the shirts sold as he adds 10$ with every purchase. His expenses start with the base cost of 1500, then he also has to pay 3 dollars for each shirt, so his expenses add up to 1500+3y. Since he wants to make as much as he spent, his revenue has to equal his expenses and 10y=1500+3y. Subtracting 3y from both sides, we get 7y=1500. Dividing both sides by 7, we get y=214.something=215 by rounding up
the break even point is when ur expenses = ur revenue...there is no profit

1.  expenses (what it costs steve ) are 1500 plus x shirts for $ 3
     revenue(what steve makes from selling shirts) are x shirts for $ 10
     so ur 2 equations would be : y = 3x + 1500 and y = 10x

2. 3x + 1500 = 10x
    1500 = 10x - 3x
    1500 = 7x
     1500/7 = 214.28....so he would have to sell 215 shirts.

4.3t-2.1t-2.3=7.6
Solve equation

Answers

If your solving for t then t = 4.5 
Final answer:

The equation can be solved by combining like terms, isolating the variable t, then dividing by the coefficient of the variable. The solution to the equation is t = 4.5.

Explanation:

The given equation in this problem is 4.3t - 2.1t - 2.3 = 7.6. To solve the equation, first we need to combine like terms, meaning we would subtract 2.1t from 4.3t.

This leaves us with 2.2t - 2.3 = 7.6. After that, we must isolate t by adding 2.3 to both sides of the equation. This results in 2.2t = 9.9. Finally, we divide both sides by 2.2 to solve for t, which gives us t = 4.5.

Please help iv added a pic of the work sheet. I have to get this done by tomorrow

Answers

You do this by moving all terms without y to the right hand side, and then divide the whole lot to keep a clean y= on the left hand side.

Moving to the other side is done by subtracting (or adding) a term from both sides. Effectively this looks like you're moving the term and flipping the sign.

So 2y + 18 = 4x changes into 2y +18 -18 = 4x -18 so 2y = 4x - 18. If you forget about the middle step, it looks like the +18 jumped to the other side and changed sign. That's all.

Second step is to change the 2y into y. You do that by dividing everything by 2. So 2y=4x-18 becomes y=2x-9

1. y=2x-9
2. y=3/2x - 6
3. y=4x+18
4. y=2x-12

5. y=-4x+18
6. y=2/3x+4
7. y=-1/4x-18/4
8. y=1/4x-18/4

9. y=1/4x+18/4
10. y=-1/4x+18/4
11. y=-3/2x+6
12. y=3/2x+6

13. y=-3/2x-6
14. y=-2/3x-4
15. y=2/3x+2/3
16. y=18-4x

Forman 1911 THE MATCH There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match. Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble. In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar. What issue made a match, or other device for starting a fire, necessary? Burning material was hard to find. Fire was hard to transport. Nature was unreliable. Wind storms were frequent.
