Luigi and Mario are growing plants for a science fair. Luigi's plant grew 11 inches in five days. Mario measured his at one foot three inches in one week. Which student has the fastest growing plants? Show work to justify your answer.
Answer:
Luigi has the fastest growing plant
Step-by-step explanation:
Luigi and Mario are growing plants for a science fair.
Mario measured his at one foot three inches in one week.
1 foot = 12 inches
Hence, the height of Mario's plant in one week
= 12 inches + 3 inches = 15 inches
Luigi's plant grew 11 inches in five days.
7 days = 1 week
5 days = 11 Inches
7 days = x
5x = 7 × 11
x = 77/5
x = 15.4 inches
Which student has the fastest growing plants?
Luigi has the fastest growing plants

Solve the problem involving systems of lineas equations
1. Your mother bought 20 kilos of mangoes and apple combined. Mango P60.00 per kilo and apple is P40.00 per kilo. If she paid P 1000.00 for 20 kilos how many kilos of each kind mother bought?
(a) If x is number of kilos of mango and number of kilos of apple, then the equation is:______
(b) Equation for the cost of fruits_______
(c) The system equations are ______ and _________
(d) Solve by any method.
(e) Check if your result will satisfy the problem.
Answer:
x = 10
y = 10
Step-by-step explanation:
60x + 40y = 1000
x + y = 20
a. If x is number of kilos of mango and number of kilos of apple, then the equation is: x + y = 20
b. Equation for the cost of fruits
60x + 40y = 1000
c. The system equations are x + y = 20 and 60x + 40y = 1000
d. Solve by any method.
60x + 40y = 1000 (2)
x + y = 20 (1)
x = 20 - y
Substitute into (2)
60x + 40y = 1000 (2)
60(20 - y) + 40y = 1000
1200 - 60y + 40y = 1000
- 20y = 1000 - 1200
-20y = - 200
y = -200/-20
= 10
y = 10
Substitute y = 10 into (1)
x + y = 20
x + 10 = 20
x = 20 - 10
x = 10
(e) Check if your result will satisfy the problem.
60x + 40y = 1000
60(10) + 40(10) = 1000
600 + 400 = 1000
1000 = 1000
Creating a system of linear equations and solving using elimination method, the number of mangoes and apples purchased is 10.
Let :
Number of apples = a Number of mangoes = bThe system of equations which could be formed :
a + b = 20 - - - - - - (1)40a + 60b = 1000 - - - - - - (2)From (1)
a = 20 - b - - - - - (3)Substitute a = 20 - b into (2)
40(20 - b) + 60b = 1000
800 - 40b + 60b = 1000
Collect like terms
-40b + 60b = 1000 - 800
-20b = - 200
b = 200/20
b = 10
Substitute b = 10 in (3) :
a = 20 - b
a = 20 - 10
a = 10
Therefore, the Number of apples and mangoes purchased is 10

When a polynomial 2x^3+3x^2+ax+b is divided by (x-2) leaves remainder 2, and (x+2) leaves remainder -2.Find a and b.
p(x) = 2x³ + 3x² + ax + b when divided by x - 2 and x + 2 leaves the remainders 2 , - 2.
Find:Value of a and b
Solution:✯ g(x) = x - 2
⟹ 0 = x - 2 [ g(x) = 0 ]
⟹ x = 2
★ p(2) = 2(2)³ + 3(2)² + a(2) + b
⟹ - 2 = 2 * 8 + 3 * 4 + 2a + b
⟹ - 2 - 16 - 12 - 2a = b
⟹ - 30 - 2a = b -- equation (1)
Similarly,
✯ g(x) = x + 2
⟹ 0 = x + 2
⟹ x = - 2
★ p( - 2) = 2( - 2)³ + 3( - 2)² + a ( - 2) + b
Substitute the value of b from equation (1).
⟹ 2 = 2 * ( - 8) + 3 * 4 - 2a - 30 - 2a
⟹ 2a + 2a = - 16 + 12 - 2 - 30
⟹ 4a = - 24
⟹ a = - 24/4
⟹ a = - 6
Substitute the value of a in equation (1).
⟹ - 30 - 2( - 6) = b
⟹ - 30 + 12 = b
⟹ - 18 = b
Therefore,
a = - 6
b = - 18.
I hope it will help you.

Linda has a shelf that is 56 over 5 inches wide. How many catalogs can Linda arrange on the shelf if each catalog is 4 over 5 of an inch thick? 14, because the number of catalogs is 56 over 5 divided by 4 over 5 9, because the number of catalogs is 56 over 5 divided by 5 over 4 22, because the number of catalogs is 56 over 5 multiplied by 4 over 5 31, because the number of catalogs is 56 over 5 multiplied by 5 over 4
Answer: 14, because the number of catalogs is 56 over 5 divided by 4 over 5.
Step-by-step explanation:
From the question, we are informed that Linda has a shelf that is 56/5 inches wide and that each catalog is 4/5 of an inch thick?
The number of catalogs that Linda can arrange on the shelf will be:
= 56/5 ÷ 4/5
= 56/5 × 5/4
= 56/4
= 14
Answer:
the answer is A 14
Step-by-step explanation:
because the number of catalogs is 5 divided by 4 over 5 9
Clare mixes 2 ½ cups of water with ⅓ cup of orange juice concentrate.
Han mixes 1 ⅔ cups of water with ¼ cup of orange juice concentrate.
Whose orange juice mixture tastes stronger? Explain or show your reasoning.
Answer:
Han had a stronger orange flavor
Step-by-step explanation:
Because he put less water in the mixture.
Answer:
I believe Han's orange juice has a stronger taste of the orange itself. Even though 1/4 is less than 1/3, the amount of water that has been mixed in with the amount of orange juice is less than the 2 1/2. Therefore Clare's is much more diluted with a weaker taste.
