Step-by-step explanation:

PLEASE GIVE BRAINLIEST

Answer 2

Answer:

10 : 2 : 3

Step-by-step explanation:

Water used = 1 litre = 1000ml

Sucrose used = 200ml

Saline used = 300ml

Ratio:

1000 : 200 : 300

10 : 2 : 3

The amount of water, sucrose and saline solution as a ratio = 10 : 2 : 3

If Peter pays $84 to buy a watch after a discount of 30%, find the original price of the watch

Answers

(Original price) - 0.30p = 84

Let p = Original Price of the watch

p - 0.30p = 84

0.70p = 84

p = 84 ÷ 0.70

p = 120

The original price of the watch is $120.

Answer:

The original price was $120.

Step-by-step explanation:

Let the original price of the watch be w.  

Then the discount is 0.30w and the discounted price is (1-0.30)w, or 0.70w.

Writing an equation in w, we get 0.70w = $84.

Solving this for w, we divide both sides by 0.70:

w = (84)/0.70 = $120

The original price was $120.

A baker at a bakery had made 20 pastries after 1 hour of work. After 8 hours, he had made 83 pastries. M= ?

Answers

9514 1404 393

Answer:

  9 pastries per hour

Step-by-step explanation:

In the 7 hours after the first, the baker made 83 -20 = 63 more pastries. That rate is ...

  (63 pastries)/(7 hours) = 9 pastries per hour

_____

Additional comment

We have chosen to interpret the question as asking for the slope of a line on a graph of pastries vs. hours. Such a graph would show you the baker started with 11 pastries already made, so didn't actually make 20 in the first hour.

Answer:

j-9

Step-by-step explanation:

combine like factors

subtract nine from both sides, j-7=-2

subtract 2 from both sides, -2-7=-9, j-9

Answer:

j-5

Step-by-step explanation:

(10j - 7) -(9j - 2) = x

(10j - 7) = x + (9j - 2)

10j - 7 = x + 9j - 2

10j - 9j -7 + 2 = x

x = ( j - 5)

in in the previous activity you solved a system of equations representing the carnival admissions using the elimination method in this activity you will solve the same system using substitution then you'll compare your solution with the solution you obtained in the previous activity by using the elimination method

the two equations from the previous activity are given below

k + a = 500 (1)
3K + 10A equals 3,600 (2)

which equation has at least one of its variables with a 1 as it's coefficient?
​

Answers

Answer:

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.

Step-by-step explanation:

We need to solve the system of equations using substitution method

The equation are:

[tex]k + a = 500--eq(1)\\3k + 10a = 3,600 --eq(2)[/tex]

For substitution method, we find value of k from equation 1 and put in equation 2

[tex]From \ eq(1) \ we \ get\\k=500-a[/tex]

Putting it in eq(2)

[tex]3k+10a=3600\\Put \ k=500-a\\3(500-a)+10a=3600\\1500-3a+10a=3600\\7a=3600-1500\\7a=2100\\a=\frac{2100}{7}\\a=300[/tex]

So, we get value of a = 300

Now finding value of k by putting value of a in equation [tex]k=500-a[/tex]

[tex]k=500-a\\Putting \ a \ =500\\k=500-300\\k=200[/tex]

So, we get value of k =200

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.
