Answer:
Step-by-step explanation:
3*3+2/3-2*6+5/6
=9+2/3-12+5/6
=11/3-17/6
take lcm of the denominator
=11*2-17*1/6
=22-17/6
=5/6
Answer:
b=9
Step-by-step explanation:
divide by 3 on both sides to get the variable (b) by itself
Answer:
$55.80
Step-by-step explanation:
First, find how much Janet saved by finding 1/5 of 15.50:
15.50/5
= 3.1
Find how much Rob saved by multiplying 3.1 by 12:
3.1(12)
= 37.2
Then, find the total saved amount by adding them all together:
15.50 + 3.1 + 37.2
= 55.8
So, they saved $55.80 in total
1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18
