D. (x + y, 3x-2y) = (7,11)​

Mathematics
1 answer:
siniylev [52]2 years ago
7 0

Answer:

x = 5, y =2

Step-by-step explanation:

I guess the question is saying x+y = 7 and 3x-2y = 11?

then there are multiple ways but

I will multiply the first one by 2 so 2x+2y = 14

you add the equations to get 5x = 25 so x = 5 plug x into the first equation you get y = 2

if that isn't what the question means just comment and I'll change it

A car is purchased for S15,500. After each year, the resale value decreases by 20%. What will the resale value be after 3 years?
butalik [34]

Answer:

3 years -> value decreases by 20% 3 times

20% -> value is 80% of the original price

1st year value (after 20% decrease) = S15,500×\frac{80}{100}

                                                           = S12,400

2nd year value (after 20% decrease) = S12,400×\frac{80}{100}

                                                             = S9,920

3rd year value (after 20% decrease) = S9,920×\frac{80}{100}

                                                            = S7,936

What’s the area of a circle with the diameter of 8 feet circle
Bogdan [553]
Area equals pi r squared, and if the diameter is 8 feet, then the radius would be 4 feet. 4 squared is 16, so if you’re answering in terms of pi, it’s 16 pi but if you’re answering in terms of feet it’s about 50.27 Feet
