The average of their maximum speeds was 260 km/h. if doubled malcolm’s maximum speed would be 80 km/h more than ravi’s maximum speed. what were malcolm’s and ravi’s maximum speeds?

Malcolm’s maximum speed is 200 km/h and and Ravi’s maximum speeds is 320 km/h.

Step-by-step explanation:

Let x and y are the maximum speeds ( in  km / h ) of Malcolm and Ravi respectively,

Then according to the question,

Again according to the question,

Equation (1) + equation (2),

3x = 600

⇒ x = = 200,

From equation (1),

200 + y = 520

⇒ y = 520 - 200 = 320

Hence,  Malcolm’s and Ravi’s maximum speeds are 200 km/h and 320 km/h respectively.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
