2x + 5 - 6x + 21 = 2(3x - 5) - 4
distribute
2x+5 -6x +21 = 6x-10 -4
combine like terms
-4x +26 = 6x -14
add 4x to each side
26 = 10x -14
add 14 to each side
40 = 10x
divide by 10
4 =x
Answer:
-24 a^2 b^7
Step-by-step explanation:
Simplify the following:
-8×3 a^2 b^4 b^3
Hint: | Combine products of like terms.
3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):
-8×3 a^2 b^(4 + 3)
Hint: | Evaluate 4 + 3.
4 + 3 = 7:
-8×3 a^2 b^7
Hint: | Multiply 3 and -8 together.
3 (-8) = -24:
Answer: -24 a^2 b^7
Answer: 25
Step-by-step explanation:
You take 100/16 and get 6.25. Then you just multiply 4 by 6.25 to get 25
<u>1 is a rational number</u> because 1 can go into 1 when dividing. <u>Irrational numbers are mostly decimals. </u>
