The sum of two numbers is 23. The difference of the numbers is 7.4. What are the two numbers?​
Brums [2.3K]
X+y=23
X-y=7.4

X+y=23
y=23-X

X-y=7.4
(23-y)-y=7.4
23-2y=7.4
-2y=-15.6
Y=7.8

X+y=23
X+7.8=23
X=15.2

Therefore the two numbers are 7.8 & 15.2

BRAINLIESTTT ASAP!! PLEASE HELP ME :)
Andrej [43]

Answer:

2017.

Step-by-step explanation:

The equation for the future sale of motorcycles

= 5.75(1.16)^t  where t is in years

For cars it is

3.5(1.25)^t

3.5(1.25)^t > 5.75(1.16)^t

(1.25)^t > (5.75/3.5) 1.16^t

t ln 1.25 > ln 1.64286 + t ln 1.16

t ln 1.25 -  t ln 1.16 > ln 1.64286

t (ln 1.25 - ln 1.16) > ln 1.64286

t > ln 1.64286 / (ln1.25 - ln 1.16)

t > 6.64 .

So the answer is in the year 2017.
