The integer -1 is part of the solution set of x > -2. True False

How do you Evaluate 3x(20-5)?

Sliva [168]

Answer: x = 5

Step-by-step explanation: First subtract 20 - 5 to get 15

then divide 15 by 3 to get 5 which is the answer

Can someone please help me??? And please be sure of ur answer :)

Answer:

1. is the last one.

2. is the 3rd one.

3. is the first one.

4. is the 2nd one.

Step-by-step explanation:

What you do is you have to get the letter by itself and it all depends on the less than or greater than signs.

For #1. -m+8>6. What you do is you minus 8 from both sides to get -m>-2. You still have a -m so you need to divide both sides by a -1. (one thing to remember is when you divide by a negative you have to switch the sign.) So your answer will be m<2. That will make the last graph the answer.

For #2. -2p< or equal to -10. What you do is divide by -2. and you need to remember to switch the sign. So your answer is p> or equal to 5.

You will do the same for the other two equations but your answers are.

#1. is the last one graph.

#2. is the 3rd one graph.

#3. is the first one graph.

#4. is the 2nd one graph.

Please Help! Simple Geometry!

Answer:

A 32.1

Step-by-step explanation:

Given two points $(x_{1} ,y_{1} ) and (x_{2} ,y_{2})$ )

distance between to points = d = $\sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} )^{2} }$

Now B is (-4,5) and A is (2,0)

So AB = $\sqrt{(-4-2)^{2} +(5-0)^{2} } = \sqrt{36 + 25} = \sqrt{61\\} = 7.810...$

C is (4,10)

So BC = $\sqrt{(-4-4)^{2} +(5-10)^{2} } =\sqrt{64 + 25) } =\sqrt{89} =9.433...$

D is (8,7)

So CD = $\sqrt{(4-8)^{2} +(10-7)^{2} } =\sqrt{16 + 9} = \sqrt{25} = 5$

E is (4,5)

So DE = $\sqrt{(8-4)^{2} + (7-5)^{2} } = \sqrt{16 + 4} = \sqrt{20} = 4.472...$

and AE = $\sqrt{(4-2)^2 + (5-0)^2} =\sqrt{4+25} = \sqrt{29} = 5.385...$

Perimeter = 7.810 + 9.433 + 5 + 4.472 + 5.385 = 32.1

Monica paid sales tax of $1.50 when she bought a new bike helmets if the sales tax rate what is 5% how much did this door charge

KatRina [158]

To find the total from the percent part you have, you divide the part by the percentage.
1.50÷0.05=30
The total is $30
The total the store charged, including sales tax, is $31.50.
