I need help on a math assignment.
Answer:
(18 , - 10)
Step-by-step explanation:
5x + 4y = 50 .... (1)
x + 2y = - 2 ... (2)
Solve (2) for "x"
x = - 2y - 2 .... (3)
(3) ----> (1)
5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4)
(4) ----> (2)
x + 2(- 10) = - 2 ⇒ x = 18
(18, - 10)

Jonas went to the store and bought 2 boxes of cereal for $2.79 each, a box of fruit snacks for $1.89, a gallon of milk for $3.19. Sales tax was $1.05. If Jonas pays with a 20-dollar bill, how much change will he receive
Answer:
$8.29

Give your answer as an improper fraction in its simplest form.
Answer:
[tex] - \frac{27}{7} [/tex]

We want to get x alone so we need to get rid of the 7 in front of it.
7x=-27
Divide each side by 7
x= -27/7

Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
-4 -4 • 3
-4 = —— = ——————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x+2
——— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x+2 = 0
Solving a Single Variable Equation:
4.2 Solve : x+2 = 0
Subtract 2 from both sides of the equation :
x = -2
One solution was found :
x = -2

A soccer coach filled a water cooler with 34.07 liters of water before a game. The players drank 29.6 liters during their game. How many liters of water were left in the cooler?
Answer:
4.47 liters
Step-by-step explanation:
To find how many liters were left, subtract the amount they drank from the original amount:
34.07 - 29.6
= 4.47
So, there were 4.47 liters of water left in the cooler.
After players drank 29.6 liters of water from 34.07 liters there is 4.47 liters of water left in the cooler.
What are some alternative names for arithmetic operations?Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.
Given, A soccer coach filled a water cooler with 34.07 liters of water before a game.
The players drank 29.6 liters during their game.
∴ Liters of water that is left in the cooler is the difference between water-filled before the game to the water drank by players during their game which is,
= (34.07 - 29.6).
= 4.47 liters are left in the cooler.
