Is the expression 3(x+1 1\2)-3 equivalent to 3x+1 1\2

Mathematics
1 answer:
Ket [755]2 years ago
3 0

Answer:

no

Step-by-step explanation:

first simplify or solve the original expression ( 3(x + 11/2)-3 )

1.  Parenthesis go first so do the 11/2 = 5.5 (x+5.5)

2. Distribute the 3 to the parenthesis (3x + 16.5)

3. subtract 3 from the expression (3x + 13.5)

Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)

They are not the same thing.

(17 Leon uses 3/4 cup water to make a serving of iced tea.
Ksivusya [100]

Answer:

A.) 12 3/4 cups

B.) 117 1/3

Step-by-step explanation:

<u>Part A</u>

If one serving of ice tea contains 3/4 cup of water, how much does 7 serving have?

To answer this, you must multiply 3/4 and 17

17 is the same as 17/1, so multiply the numerators and denominators

17 x 3 = 51

1 x 4 = 4

51/4 = 12 3/4

So, Leon used 51/4 or 12 3/4 cups of water

<u>Part B</u>

If the cooler has 88 servings of tea, how many cups of water does it have?

To solve this, divide 88 by 3/4

Dividing 88 by 3/4 is the same as multiplying 88 by 4/3.

Again, 88 is the same as 88/1 so multiply the numerators and the denominators.

88 x 4 = 352

1 x 3 = 3

352/3 = 117 1/3

So, there are 352/3 or 117 1/3 cups of water in the cooler

I hope this helps!

Supplementary angles are angles that equal 180 degrees.

Transitive property : if two angles (segment) are each congruent to a third segment (angle) then they are both congruent to each other.
