Answer:

Step-by-step explanation:

Given

w + 1 = d...........equation 1

d = 3w ...............equation 2

Now putting d = 3w in equation 1

w + 1 = 3w

3w - w = 1

2w = 1

w = 1 / 2

putting w = 1 / 2 in equation 2

d = 1 / 2 * 3

 = 3/2

Hope it helps :)

Step-by-step explanation:

d = 3w

so... if we substitute value of d in eqn 1 then

w + 1 = 3w

or, 3w - w =1

w = 1/2

now..

d = 3* (1/2)

d= 3/2 ans..

I’m begging you help me!!! 1. The table below shows 3 recipes for a fruit punch
wariber [46]

Answer:

The answer to this question is given below in the explanation section.

Step-by-step explanation:

The table shows three different recipes. In this question, it is asked that will all the recipes taste same. To obtain the answer to this question, first, we measure the taste of each recipe in terms of calculating the ratio.  

Water ............................. Cups

     1   ............................. 3

    4   ............................. 12

    6   ............................. 18

1. The fraction of the first recipe is 1/3 so the ratio is 1:3(water to cup)

2. The fraction of the second recipe is 4/12

which can be simplified as 4/12=1/3 so the ratio is 1:3(water to cup)

3. The fraction of the third recipe is 6/18

which can be simplified as 6/18 = 3/9 = 1/3 so the ratio is 1:3(water to cup).

So based on the above answer, all recipes taste the same.

Answer 2:

No recipe taste different, all the recipe taste the same. Because all the recipe ratios are equivalent.

the sum of two numbers is 57. if the larger of the two numbers is 9 less than twice the smaller, find the two numbers
svp [43]

Answer:

The answer is 35 and 22

Because:

U let the numbers(#) be x and y (x will be the larger number and y the smaller number

So:

x + y =57

x = 2*y - 9

Therefore,

{2*y - 9} + y = 57

Leaving the two numbers 35 and 22

Ishaan and his friends have 40$ to spend at a restaurant.
Paul [167]

The number of salads Ishaan and his friends can afford is 6 salads.

<h3>What are Word Problems?</h3>

Word Problems in mathematics involve crucial understanding and the use of variables and arithmetic operations to solve real-life cases.

From the given information;

  • The total amount with Ishaan and his friends = $40
  • If they decided to spend the money on salad(x) and one salad(x) cost = $6

Thus, the number of salads they can purchase is:

\mathbf{x = \dfrac{\$40}{\$6}}

x = 6 salads remaining $4

Therefore, we can conclude that the number of salads they can purchase with $40 is 6 salads with a remaining amount of $4.
