Answer:
15years
Step-by-step explanation:
6000×10×t÷100=9000
600t=9000
t=9000÷600
t=15years
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
.
<span>Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2

I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
Answer:
Step-by-step explanation:
<u>The difference of −2d and −3d is equal to the difference of 1/6 and 1/3</u>
- -2d - (-3d) = 1/6 - 1/3
- -2d + 3d = 1/6 - 2/6
- d = -1/6
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
