Answer:
x = -7
Step-by-step explanation:
7x-3 - 2x = -38
7x -2x = -38+3
5x = -35
x = -35/5
x = -7
First question: x= 1 2/3 + y
y= -1 2/3 - x
second question: y= 6 - 7x
x= y + 6/7
Answer:
Variable
x which stands for no. of toppings on pizza
equation
7 + 1.5x = 11.50
solution
the no. of toppings = 3
Step-by-step explanation:
Let the number of topping be x.
Cost of 1 topping = $1.50
Cost of x topping = x*Cost of 1 topping = $1.5*x = $1.5x
Cost of cheese pizza = $7.00
Total cost for cheese pizza for x topping = Cost of cheese pizza + Cost of x topping
Total cost for cheese pizza for x topping = 7 + 1.5x
Given that The total charge for Megan's pizza was $11.50
thus,
7 + 1.5x = 11.50
1.5x = 11.50 - 7
1.5x = 4.5
x = 4.5/1.5 = 3
Thus, there were three toppings

Answer:
x=7/5
Step-by-step explanation:
First you need to get X by itself. You simplify the right side, getting -5, and then subtract 9 from both sides, getting -10x on one side and -14 on the other. Divide both sides by -1, getting 10x=14, divide both sides by 10 which leaves x=14/10. This can be simplified to be 7/5
Answer:
the right answer is a) 23
Step-by-step explanation:
because when we analyze the sequence it is observed that all the numbers are added the value of 3, therefore when arriving at position 10 the sum is 23
