Answer:

B. -1

Step-by-step explanation:

-7-[-6]

Double negatives equal a positive so instead of it being -[-6] it would be +6 and -7+6 = -1

Hope this helps!

Find the least common multiple of 8x³y6z, 6x5z², and 10yzº.

kvv77 [185]

Answer:

The Least Common Multiple (LCM) of $8x^3y6z,6x5z^2, \text{ and } 10yz^0 \text{ is } 240 x^3yz^2$

Step-by-step explanation:

Definition of LCM

The LCM of a, b , c is the smallest multiplier that is divisible by a, b and c

Here the three terms are :

$8x^3y6z$

$6x5z^2$

$10yz^0=10y$ since $z^0 = 1$

Factoring using prime factorization we get $8x^3y6z = 2.2.2.x^3.y.2.3.z$ ³

= $2^4\cdot \:3\cdot \:x^3\cdot \:y\cdot \:z$ (1)

Factoring $6x5z^2$ we get

$2\cdot \:3\cdot \:5\cdot \:x\cdot \:z^2$ (2)

Factoring $10yz^0$ we get

$2 \;\cdot\; 5y$ ( $z^0 = 1)$ (3)

The LCM is the multiple of each of the highest power in each factor

$2^4\;.\;3\;.\;5\;.x^2\;.\;y\;.z^2 = 240 x^3yz^2$

3 pounds of grapes cost $5.07. Rounding to the nearest tenth, how many pounds can you purchase for $13.00?

Natali5045456 [20]

So the tenth place is the x in this number 2.x

so rounding to the tenth 5.07
7>5 so round up to 10
5.10

so 13.00

5.10=3 pounds
try and divide by 3
1.7=1 pound

divide 13 by 1.7
13/1.7=7.6 pounds
