What is the cost of one sandwich?


What is the cost of 1 sandwich 1 salad and 1 juice?

Answers

Answer 1

Answer:

Below in bold.

Step-by-step explanation:

Let cost of sandwich = s,  juice = j and salad = d.

2s + j = 500     (A)

s + d = 510       (B)

d + j =  530      (C)

Equation  (C) - (B)   ( to eliminate d):

j - s = 20          (D)

(A)  - (D) =   (to eliminate j):

2s - (-s) = 480

3s = 480

s = 160

A sandwich costs E 1.60.

Find the value of x. The diagram is not to scale.

Answers

Consider Z the third angle in the image;

105 + z = 180

z = 75

72 + x + z = 180

72 + 75 + x = 180

x = 33

Alternative D)

X=33. 105 shares a line and a line is equal to 180. 180-105= 75. Then add 75 +72= 147. Then 180-147=33. A triangle is 180 degrees

Two digits of the 5-digit number A = 74*9* are missing. Fill in the missing digits so that the number obtained is the smallest possible number that is divisible by 45. Find A.

Answers

Answer:

A = 74295.

Step-by-step explanation:

74*9*

- the last number must be a 0 or a 5.

So we try 74090/45 -  not an integer

74095/45 = No

74190/45 No

74195/45  No

74295 / 45 = 1651 So that's it,

The required model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B. Option B is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

What is an array?

The array is a collection of things and shapes in a specific pattern.

Here,

Given that, to determine the model that represents 9 (3+6) = (9 x 3) + (9 x 6)

So 9 (3+6) = (9 x 3) + (9 x 6) represents the arrangement of squares in array form,

If in a pattern there are 9 rows there must be 3 and 6 columns or vice versa.,

So from the above definition, a model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B.
