Answer:
$27
Step-by-step explanation:
0.3 x 90 = $27
30% of your money is $27, so the football must've cost $27.
To get 10% of your calories from polyunsaturated fats you would need to eat 200 calories worth. So 1 serving of walnuts would give you 180 calories. So one serving of walnuts would be 9% of your daily calories.
As sum of all angles of triangle equal to 180 degrees.
First we have to add the angles.
50+75+55
=50+130
=180 degrees
Answer: Zipora can construct exactly one triangle.
Answer: 2 1/4 more flour for 9 servings
Step-by-step explanation: (a) how many total cups of flour are there per serving? show your work
1 1/2÷6= 3/2 x 1/6 = 3/12= 1/4 cups of flour per serving
(b) how many total cups of sugar (white and brown) are there per serving?show your work
3/4 + 1/3 = 9/12 + 4/12= 13/12= 1 1/12 total cups of sugar
13/12 ÷ 6/1 = 13/12 x1/6 = 13/72 per serving
(c) supposed you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe?Show your work/
1/4 x 9 = 9/4 = 2 1/4 more flour for 9 servings.
Answer:
x = 5 , y = 15
Step-by-step explanation:
You can solve this using substitution.
Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y
2x + 1y = 25
x + y = 20
These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).
For part B I used substitution because it was more applicable to the question then addition or elimination.
ACTUAL WORK
Set 2x + 1y = 25 equal to x
x = 25 - y / 2
Replace x with y in the second equation
(25 - y / 2) + y = 20
And solve for y
y = 15
Since we know what y is we can replace y in the second equation and find what x is
x + 15 = 20
Solve for x
x = 5
