The rules for multiplying and dividing decimals are;
Multiplying decimals:
- Multiply as usual, ignoring the decimals.
- Determine the total number of digits behind the original numbers' decimal points.
- Place the same number of digits behind the decimal point in the product.
Dividing Decimals:
-If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.
- Divide as usual. ...
- Put decimal point directly above decimal point in the dividend.

Answer:
Work done = 3750 Joules
Step-by-step explanation:
The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem
Horizontal component= 150 * cos 60
Horizontal component= 150*0.5
Horizontal component= 75N
Work done= Force * distance
Work done= 75*50
Work done= 3750 Nm
Work done = 3750 Joules
Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
m = amount of money you receive
You need at least $40, so that means you need m = 40 or more
So
which is the same as saying
. You flip both sides and also flip the inequality sign as well.
At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means ![m \le 50](https://tex.z-dn.net/?f=m%20%5Cle%2050)
-----------------
Combine
and
to get the compound inequality ![40 \le m \le 50](https://tex.z-dn.net/?f=40%20%5Cle%20m%20%5Cle%2050)
This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.

Answer: ![40 \le m \le 50](https://tex.z-dn.net/?f=40%20%5Cle%20m%20%5Cle%2050)
