Answer:

8. Flour = 150 grams

9. Original sum of money = 110 pounds

Step-by-step explanation:

8. Let the quantities of butter, flour and sugar be 2x, 3x and 4x grams respectively.

So,

2x + 3x + 4x = 450

9x = 450

x = 450/9

x = 50

Flour = 3x = 3*50 = 150 gram

Let Abby, Neil and Dylan have 2x, 4x and 5x pounds respectively.

Since Neil has 40 pounds.

So, 4x = 40

x = 40/4

x = 10

Total amount = 2x + 4x + 5x = 11x = 11*10 = 110 pounds.

Original sum of money = 110 pounds

Here is a formula for the amount of water needed to cook rice.

w = 1.5r + 0.5

w is the number of cups of water needed.

r is the number of cups of rice to be cooked.

(a) How many cups of water are needed to cook 7 cups of rice?

(b) How many cups of rice can be cooked with 20 cups of water?

Answers

Step-by-step explanation:

So w =water.

1 cup of water is equal to 1.5 times the volume of rice +0.5

so it'd be (11x1.5) + 0.5 for part A and for part B so you'd need to rearrange the equation which i'm not confident on .

W= (1.5 x11)+0.5

W=17

29=(1.5 x r) + 0.5

28.5=1.5r

19= r

Jesse has to save 60% of the total cost to go to a sports camp during the summer. The total cost was $500. What was the total amount Jesse saved? Make sure to explain how you got it.

Answers

Answer:

$300

Step-by-step explanation:

The total cost is $500 so you must find 60% of that. To find percentage divide 60% by 100 which turns it into .60, and then you multiply .60 by 500. This equals to 300. So, Jesse 60% of 500 is 300, and so Jesse had to save $300

What is 3х – 18y = 4

Answers

The answer is no solution

Simplifying
3x + -18y = 4

Solving
3x + -18y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18y' to each side of the equation.
3x + -18y + 18y = 4 + 18y

Combine like terms: -18y + 18y = 0
3x + 0 = 4 + 18y
3x = 4 + 18y

Divide each side by '3'.
x = 1.333333333 + 6y

Simplifying
x = 1.333333333 + 6y

The total number of combinations will be equal to the product of the numbers of options for each selection.

Here we know that:

"Buy a sandwich and get either a snack or a drink for free."

Then we have two selections:

Sandwich, where we have 11 different types.

Snack or a drink (we can choose only one) there are 9 options for snacks, and 5 options for drinks, then there is a total of 9 + 5 = 14 options.

The total number of different combinations is:

Combinations = 11*14 = 154

There are 154 different meals that you can get on the offer.

Find the measure of the exterior angle. 86° 46° xº.

Answers

The measure of the exterior angle x° is equal to 132° considering the exterior angle x° has 86° and 46° as its interior opposite angles of a triangle.

Exterior angle of triangles

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

To calculate for the exterior angle x°, we shall ad the two interior opposite angles of the triangle to derive their value, and thus equate to the unknown exterior angle x°.

interior opposite angles are 86° and 46°

sum of interior opposite angles = 86° + 46°

sum of interior opposite angles = 132°

so;

x° = 132°

In conclusion, the exterior angle x = 132° for the triangle whose two interior opposite angles to x are 86° and 46°.
