<span>6 (378) = 2268 = (189 + 189)6

The properties include:
Addition: you can compute 6 + 107 = 113 </span>
Commutative Property by altering: 107 + 6 = 113
Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113
Distributive Property by distributing: 2 (3) + 107 = 113

In terms of multiplication, you can calculate 6 x 107 = 642
Commutative Property by rearranging: 107 x 6 = 642
Associative Property through grouping: (3 + 3) x (100 + 7 ) = 642
<span>Distributive Property by distributing: 2(3) x 107 = 642

Describe two ways to solve the equation 2(4x-11)=10

AnnZ [12381]

2(4x-11) = 10

Method 1:
Divide both sides by 2:
$\frac{2(4x-11)}{2} = \frac{10}{2}$

$4x-11 = 5$

Then add 11 to both sides:

$4x-11+11 = 11+5$

$4x = 16$

Finally divide both sides by 4

$\frac{4x}{4} = \frac{16}{4}$

$x = 4$

Method 2:

Use the distributive property:

$2(4x-11) = 10$

$2*4x- 2*11 = 10$

$8x - 22 = 10$

Add 22 to both sides:

$8x - 22+22 = 10+22$

$8x = 32$

Then divide both sides by 8

$\frac{8x}{8} = \frac{32}{8}$

$x = 4$

in a ceremony out of 800 participants 620 drink milk 350 drank tea and 50 did not drink both. find out how many people drank the

Leona [12618]

220: goodnight, mark me brainliest Explanation: Let M symbolize the count of people who drank milk, while T denotes those who consumed tea. Let x indicate the number who had both milk and tea. Consequently, the count of individuals who drank only milk is represented by n(M ∩ T') = 620 - x, and those who drank only tea is n(M' ∩ T) = 350 - x. Since 800 individuals took part, we have: 620 - x + (350 - x) + x + 50 = 800, simplifying to 1020 - x = 800. Therefore, x = 220. Thus, 220 individuals consumed both beverages.
