the sum of Kris and Victor's ages is 27 years. in 3 years, victor will be twice as old as Kris will be. what are their present ages?

Answers

Answer 1

Answer: let k=kris and victor =v
k+v=27
in 3 years, victor will be twice as old as kris will be.so
v+3=2(k+3)
v=2k+6-3
v=2k+3
so (2k+3)+k=27
3k=24
k=8 27-8=19
kris is 8 years now. victor is 19 years old.

Answer 2

Answer: LET KRIS'S AGE BE X YEARS AND VICTOR'S AGE BE Y YEARS
GIVEN, X + Y = 27 ------------EQ 1
IN THREE YEARS,
KRIS WILL BE X+3 YEARS AND VICTOR WILL BE Y+3 YEARS
GIVEN , Y+3 = 2(X +3 )
Y+3 = 2X+ 6
Y - 2X =6-3
Y - 2X =3 ------------EQ 2
FROM EQ 1 WE GET,
X =27 -Y
SUBSTITUTING THE VALUE OF X IN EQ 2 ,WE GET
Y - 2(27 -Y) =3
Y - 54 +2Y =3
3Y-54 =3
3Y =57
Y=57/3 =19
PUTTING THE VALUE OF Y IN EQ 1
X +19 =27
X =27-19=8
THEREFORE, KRIS IS 8 YEARS OLD AND VICTOR IS19 YEARS OLD

What is yr answer ???

Answers

$(30+2x)/(10)=3.60\ \ \ \ /\cdot10\n\n30+2x=36\ \ \ \ /-30\n\n2x=6\ \ \ /:2\n\nx=3\ (\$)$

$Answer:\$3\ (4)$

ok soo if the 10 items avg $3.60 each then your total for the ten items was $36. if we know that the cost of 8 items is $30 then there is 6 dollars left. nd if we no that the remaining 2 are the same price then each should be $3

Rita and Tina each make $11 an hour working as cashiers at a supermarket. Last week, Rita worked r hours while Tina worked t hours. Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage. Which expressions represent the total weekly wages of both Rita and Tina?

Answers

For Rita
=> 11 dollars (r) + 32 dollars - r is for the number of hours she worked and the additional 32 dollars is for her over time.
For TIna
=> 11(t) - T is for the number of hours tina worked in the supermarket.

Answer: Equation for Tina be $11t$

Equation for Rita be $11r+32$

Step-by-step explanation:

Since we have given that

Number of hours Rita worked for = r

Number of hours Tina worked for = t

Cost per hour = $ 11

Amount for overtime Rita earned = $32

So, the equation expressing total weekly wage for Tina be $11t$

The equation expressing total weekly wage for Rita be $11r+32.$

NEED HELP NOW!!!!!!!a 5 inch bamboo shoot doubles in height every 3 days. if the equation y=ab^x , where x is the number of doubling periods , represents the height of the bamboo shoot, what are the values of a and b?

Answers

Answer a = 5 and b = 2.

Procedure

Initially means x = 0, then

5 = a*b^0 = a*1 = a, then a = 5

When x = 1, the height is the double of 5, i.e 10 and

10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2

The a = 5 and b = 2, so the equation is y =5(2)^x
