The sum of person x and person y is 2640. if person x's income is 20% more than person y, find person x's income.
Masja [62]

Answer:

I do not understand she question do you mean the sum of their income is 2640

if so, then the answer is 440 to be x income

Step-by-step explanation:

x income = 20% or 1/5 of y income

y income = 5 of x income

we know that the sum of their income = 2640

which means that

x + y = 2640 =

1/5y + y = 2640

6y/5 = 2640

cross multiply to give us

6y = 5(2640)

6y = 13200

divide through by 6 to give us,

6y/6 = 13200/6

y = 2200

since we know that x income is 20% y income,

therefore, x income =

20/100 * 2200

= 440

therefore,

x income = 440

y income = 2200

How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimete
Lady bird [3.3K]

Answer:

L = 62.5cm; B = 30cm

Step-by-step explanation:

P = 2 (L+W): L=25cm; W=12cm

=2 (25+12)

=50+24

P = 74cm

For a congruent rectangle with P = 185cm

A: 74 = 2 (25 + 12)

B: 185 = 2( ? + ?)

Since A/B are congruent;

185/75 = 2.5

B = 2 (2.5* (25 + 12)

= 2 ( 62.5 + 30)

= 125 + 60

= 185

Hence, B: L = 62.5cm; B = 30cm

185cm = 2 (62.5 + 30)
