Answer:

40 2/5Ibs or $40\frac{2}{5}$ lbs

Step-by-step explanation:

Let weight of object on the moon be represented = Wm

weight of object on the Earth = We

In the above question, we are told:

The weight of an object on the moon is

5 of its weight on Earth.

Hence, mathematically, this is represented as:

5Wm = We

If a moon rock weighs 202 lbs on Earth

5Wm = 202lbs

Wm = 202lbs/5

Wm = $40\frac{2}{5}$ Ibs

Therefore, the moon rock weighs $40\frac{2}{5}$ Ibs on the moon.

Q + 5/9= 1/6 from big ideas mathbook

Alika [10]

9We have such eqation
Q $+ \frac{5}{9} = \frac{1}{6}$ /*9 (multiply both sides by 9)
9Q+5= $\frac{9}{6}$ /-5 both sides
9Q= $\frac{9}{6}- 5$
9Q= $\frac{9}{6}- \frac{5*6}{6}$
9Q= $\frac{9-30}{6}$
9Q=- $\frac{21}{6}$ /:9 divide both sides by 9
Q=- $\frac{21}{6}:9$
Q $\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}$ - its the answer

A department store sold 51 51 shirts one day. All short-sleeved shirts cost $14.00 $ 14.00 each and all long-sleeved shirts cost

Dmitrij [34]

Answer:

28 short-sleeved shirts were sold and 23 long-sleeved shirts were sold.

Step-by-step explanation:

We can solve this question by a system of equations.

I am going to say that:

x is the number of short-sleeved shirts sold.

y is the number of long-sleeved shirts sold.

A department store sold 51 shirts one day.

This means that $x + y = 51$

All short-sleeved shirts cost $14.00 each and all long-sleeved shirts cost $23.00 each. Total receipts for the day were $921.00.

This means that

$14x + 23y = 921$

How many of each kind of shirt were sold?

We have to solve the system of equations.

$x + y = 51$

$x = 51 - y$

--------------

$14x + 23y = 921$

$14(51 - y) + 23y = 921$

$714 - 14y + 23y = 921$

$9y = 207$

$y = \frac{207}{9}$

$y = 23$

--------

$x = 51 - y = 51 - 23 = 28$

28 short-sleeved shirts were sold and 23 long-sleeved shirts were sold.

Will someone please help me with this because I don't understand and I don't want to fail my class.

Marrrta [24]

Answer:

4y + 1 = 4 - 5y

First option

Step-by-step explanation:

x - 4y - 1 =0; add both sides by + 4y + 1

x - 4y - 1 + 4y + 1 = 0 + 4y + 1

Simplifying

x = 4y + 1

x + 5y - 4 = 0; Add (-5y + 4) to both sides

x + 5y - 4 -5y + 4 = 0 -5y + 4

Simplying

x = -5y +4

x = 4 - 5y

Now you have both equations

x = 4y + 1

x= 4 - 5y

Now you can use the comparison method

4y + 1 = 4 - 5y

Help! Will give branliest!!

sergey [27]

Hello from MrBillDoesMath!

Answer:

sin(A) = k/c

sin(C) = k/a

Discussion:

By definition of sine ,

sin(A) = side opposite angle / hypotenuse = k/c

sin(C) = side opposite angle/ hypotenuse = k/a

Added remark:

From the first equation, k = c sin(A). From the second equation k = asin(C). Hence.

asin(C) = csin(A) => divide both sides by "ac"

sin(C)/ c = sin(A)/a

Which is the law of sines for a triangle.

Thank you,

MrB
