The ratio of an object's weight on Earth to its weight on Mars is 5 to 2. How much would a man, who weighs 145 pounds on Earth,
butalik [34]
To answer this youd have to set up a proportion. 5/2 is the ratio of weight on earth and mars respectively. The other side has to have the same ratio where 125lbs is the weight on earth and x is the weight on mars. The equation would look like 5/2=125/x. Youd have to cross multiply, and would get (125)(2)=5x. Solve for x to find the weight on mars

the diffrence of two numbers,a and b,is 21,the diffrence of five times a and two times b is 18 what are the values of a and b
Triss [41]

Answer:

a=-8

b=-29

Step-by-step explanation:

Let's assume

first number is a

second number is b

the difference of two numbers,a and b,is 21

so, we get

a-b=21

we can solve for 'a'

a=b+21

the difference of five times a and two times b is 18

so, we get

5a-2b=18

now, we can plug 'a'

5(b+21)-2b=18

now, we can solve for b

5b+105-2b=18

3b+105=18

3b=-87

b=-29

now, we can find 'a'

a=-29+21

a=-8
