Answer:\

x ≥ 6

Step-by-step explanation:\

4x -30≥ - 3x + 12

add 30 to bot size

4x - 30 + 30 ≥ -3x + 12 + 30

simplify

4x ≥ -3x + 42

add 3x to bot sides

4x +3x ≥ -3x+42+3x

simplify

7x ≥ 42

divide bot sides by 7

7x/7 ≥ 42/7

simplify

x ≥ 6

What is the surface area of a triangular pyramid if each face has an area of 30 mm2?A.
90 mm2

B.
160 mm2

C.
60 mm2

D.
120 mm

Answers

The answer must be $120\quad m{ m }^( 2 )$ since the triangular pyramid has 4 faces and each has an area of 30 $m{ m }^( 2 )$ we should multiply that by 4 , so :

$4\cdot 30\quad m{ m }^( 2 )=\quad 120\quad m{ m }^( 2 )$

Answer:

120 i think

What two numbers multiply to 12 and add to 8

Answers

to get the answer, lets first make the factors of 12
1 * 12 = 12
2 * 6 = 12
3 * 4 = 12

Now we can easily get our answer, we know
1 +12 =13 so this is not a correct option.
3 + 4 = 7 this is also not the correct answer.
6 + 2 = 8 this is the correct answer

Hope this helped you.. :)

Your answer would be 6 and 2.
Six times two equals 12, and when 6 is added to 2, it equals 8.

A drum set originally costs $500, but it is on sale for 20% off. If a customer buying the drum set has a $70 gift card, what will her final price be on the drum set?

Answers

20% of $500 is $100, so you take away $100 from $500.
= 500 - 100

This leaves you $400. When the customer buys the drum set, you take $70 off of $400;

400 - 70
which leaves you with $330 as the final price.

20% of 500 is 100 so 500-100=400 and then with the 70 dollar gift card you have to do 400-70 which is 330. The final price is $330
