Answer: 6 2/3

Step-by-step explanation:

So 1/2 could also mean 3/6. 3 3/6 + 3 1/6 = 6 4/6 or 6 2/3 as a simplified answer

Answer: 6 2/3

Step-by-step explanation:

First, you would need to find a like denominator. 2 goes into 6 3 times, so we have to multiply the numerator by 3. 1 x 3 = 3. so it becomes 3/6. 3/6 + 1/6 = 4/6 and 3+3 = 6, so the answer is 6 4/6. After simplifying it to its lowest term, the answer is 6 2/3.

What is the decimal multiplier to increase by 99%? need it now

krek1111 [17]

Answer:

To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2.

Find x(3x+72) triangle

Alinara [238K]

Answer: x = -4 ; Angle = 60°

Concept:

The given figure is a triangle with 3 arc signs on each angle. This arc sign stands for the corresponding angles are congruent, which in this question, it shows that all three angles are congruent. Sometimes, if the figure has multiple angles and there are different groupings of congruent angles, then we use different numbers of arcs or symbols.

Solve:

Given information

An angle = 3x + 72

Total measure of angles = 180 (triangle angle sum theorem)

Total number of congruent angles = 3

Given expression

Total measure = Total number of congruent angles × An angle measure

Substitute values into the expression

180 = 3 (3x + 72)

Divide 3 on both sides

180 / 3 = 3 (3x + 72) / 3

60 = 3x + 72

Subtract 72 on both sides

60 - 72 = 3x + 72 - 72

-12 = 3x

Divide 3 on both sides

-12 / 3 = 3x / 3

$\boxed{x=-4}$

Find the angle measure

3x + 72 = 3 (-4) + 72 = $\boxed{60}$

Hope this helps!! :)

Answer:

1 tenth and 9 hundreds

Step-by-step explanation:

Ok so this is not a gud explanation but believe me that answer is correct

a tenth is 10% out of a hundred so thats 10/100 and since the 9 hundreds is already there 10/100+ 9/100= 19/100

Hope you have a gud day :)
