5x2−3y
Answer:
Step-by-step explanation:
Put x = 4, y = -5 and z = 2 to the expression 3x² - 4y + xz and use PEMDAS:
3(4)² - 4(-5) + (4)(2)
= 3(16) + 20 + 8
= 48 + 20 + 8
= 76
Answer:
44
Step-by-step explanation:
Alright let’s do this!
Expression: 5x^2 - 3y and x = 4, y = 12
First let’s plug in the missing values of x and y!
5(4)^2 - 3(12)
Then, get rid of exponent! From this point forward follow PEMDAS
5(16) - 3(12)
80 - 36 =

What is 4a+8b in simplified form?
The simplest form of (4a + 8b) / 12 is (a + 2b) / 3.
Given is an expression (4a + 8b) / 12, we need to simplify it in simpler form,
To simplify the expression (4a + 8b) / 12, you can divide both the numerator and the denominator by their greatest common divisor (GCD) to reduce the fraction to its simplest form.
First, let's find the GCD of 4 and 12. The factors of 4 are 1, 2, and 4, and the factors of 12 are 1, 2, 3, 4, 6, and 12.
The largest number that appears in both sets of factors is 4, so the GCD of 4 and 12 is 4.
Dividing both the numerator and the denominator by 4, we get:
(4a + 8b) / 12 = (4(a + 2b)) / (4 x 3)
Canceling out the common factor of 4:
(4(a + 2b)) / (4 x 3) = (a + 2b) / 3
Therefore, the simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

Answer:
357
Step-by-step explanation:
Create an equation:
Let x represent your age.
1114 - 2x = 400
Solve for x:
1114 - 1114 - 2x = 400 - 1114
-2x = -714
-2x / -2 = -714/-2
x = 357

Amy takes a job as a car salesman. She makes $700 per car she sells, and she earned a $100 bonus when she agreed to work for the car dealership. Write an equation that shows how much Amy will have earned (E) after selling 'c' cars. Use that equation to determine how many cars. Amy must sell in order to have earned a total of $14,800. That is the unlock number.
ILL GIVE U BRANLIEST
Answer:
E = 700c + 100 and 21 cars
Step-by-step explanation:
Let c be the number of cars that Amy sells. The initial salary that Amy gets is 100, no matter how many cars that Amy sells. However, she also makes 700 dollars for every car she sells, or c. Therefore, we have the equation:
E = 700c + 100
with E representing how much money Amy gets. We use this equation for part B. She must make 14800 dollars, which we substitute for E, because that is how much she makes. Therefore, we have:
14800 = 700c + 100.
We solve this equation and get c = 21, so Amy has to sell 21 cars.
Answer:
To earn a total of $14,800 Amy would need to sell 21 cars (Read explanation for equation)
Step-by-step explanation:
$700 per sale of 1 car
$100 Bonus (1 time)
c=Cars
E=Earned
Equation: E=(700•c) +100
To find how many cars amy would need to sell to reach 14,800, Replace "E" With 14800
14800 = (700•c) +100
