Lira has flowers. 2/9 of them are roses, and 3/7 of the remainder are sunflowers and the rest are tulips. If she has 36 tulips, how many sunflowers and roses does she have all together?

Answers

The total sunflowers and roses Lira has is 18 and 27 respectively

Let

Total flowers = x

Roses = 2/9 of x

= 2/9x

Remaining = x - 2/9x

= (9x-2x) / 9

= 7/9x

Sunflowers = 3/7 of 7/9x

= (3 × 7)/(7 ×9)x

= 21/63x

Tulips = 36

Total = roses + sunflowers + tulips

x = 2/9x + 21/63x + 36

x - 2/9x - 21/63x = 36

(63x -14x-21x) / 63 = 36

28/63x = 36

cross product

28x = 36 × 63

28x = 2268

x = 2268/28

x = 81

Therefore,

Total flowers = x

= 81 flowers

Roses = 2/9x

= 2/9 × 81

= 18 flowers

Sunflowers = 21/63x

= 21 / 63 × 81

= 27 flowers

Step-by-step explanation:

The range of the given numbers is 5 to 48. In order for x to make the range be 67, the value of x must be 67 less than 48, or must be 67 greater than 5.

  x is 48 -67 = -19

Step-by-step explanation:

We can add 6 times the first equation to the second equation in order to eliminate y.

  6(x -y) +(4x +6y) = 6(-1) +(-74)

  10x = -80

  x = -8

Watson and Alva each have the same total number of toy cars and trucks Watson has 4 boxes. Each of his boxes has 7 cars and 2 trucks. Alva
has 2 boxes. Each of his boxes has 11 cars and the same number of trucks
How many trucks are in each of Alva's boxes?

Answers

Answer:

Alva has 7 trucks in each box.

Explanation:

You need to determine the total number of toys Watson has. Watson has 4 (7+2) = 4(9) = 36 toys.

Set 36 equal to an expression for the number of toys Alva has. Using t for the number of trucks, 36 = 2 (11+t).

Then, solve the equation.

36 = 2(11+t) 36 = 22 + 2t 14 = 2t7 = t

So how many trucks are in each of Alva's boxes?

7 Trucks!

The number of trucks that Alva has is 7.

How many trucks does Alva have?

A linear function is a function that is made up of a single variable that is raised to the power of one.

The general form of a linear equation is:

y = mx + b

Where:

y = dependent variable b = constant m = independent variable

The first step is to determine the total number of toy cars and trucks that Watson has.

Total number of toy cars and trucks that Watson has = (4 x 7) + (4 x 2)

= 28 + 8 = 36

Since Watson and Alva have the same number of toy cars and trucks, it means that Alva would also have 36 toy cars and trucks.

The equation that represents the total number of toy cars and trucks that Alva has is:

(2 x 11) + (2 x t) = 36

22 + 2t = 36

36 - 22 = 2t

14 = 2t

t = 14 / 2

t= 7
