Manny plans to save 1/12 of his salary each week. If his Weekly salary is $372, find the amount he will save each week.

xxMikexx [17]

Answer:

$31

Step-by-step explanation:

We know that Manny makes $372 in a week. If he needs to save 1/12th of his salary a week, we would need to multiply 372 by $\frac{1}{12}$ .

$x=372(\frac{1}{12})$

$x=31$

This means that Manny would end up saving $31 each week.

there are 13 animals in a barn. some are ducks and some are pigs. there are 40 legs in all. how many of each animal are there?

konstantin123 [22]

Let X be chickens
Let Y be pigs,
then x+y=13
the animals have 2x+4y legs,
so 2x+4y=40
The system of the equations
[X+y=13
[2x+4y=40
Divide the second equation by 2
[x+y=13
[x+2y=20
subtract the first equation from the second one
y=20-13
y-7 pigs
substitute y=7 into the first equation
x+7=13
x=13-7
x=6 chickens

Point P is on line segment OQ. Given OQ = 4x + 2, PQ = 4x – 10, and

Verizon [17]

Answer:

Step-by-step explanation:

Since, Point P is on line segment OQ.

$\therefore O - P - Q\\\\\therefore OP + PQ = OQ\\\\\therefore 3x - 3 + 4x - 10 = 4x + 2\\\\\therefore 7x - 13 = 4x + 2\\\\\therefore 7x - 4x = 2 + 13\\\\\therefore 3x = 15\\\\\therefore x = \frac{15}{3}\\\\\huge \purple {\therefore x = 5} \\\\OQ = 4x + 2 = 4\times 5 + 2 = 20 + 2\\\\\huge \orange {\boxed {OQ = 22}}$
