Answer:
Ranger's simplified expression was 0.1x + 18.2
The correct answer is the first option.
Step-by-step explanation:
To simplify the given expression
3(2.7x + 5) – 2(4x – 1.6)
First, we will open the brackets by distributing 3 and 2, that is
(3×2.7x) + (3×5) -(2×4x) -(2×-1.6)
Now, we will get
8.1x + 15 - 8x +3.2
Now, collect like terms,
8.1x - 8x + 15 + 3.2
Then, we will get
0.1x + 18.2.
Hence, Ranger's simplified expression was 0.1x + 18.2.
The correct answer is the first option.
Hello!
The scale factor is what the first item was multiplied by to get the second item
there are 12 inches in a foot
Because of the the answer is 1/12
the answer is 1/12
Hope this helps!
In the future, please use commas and periods. It was difficult to decipher where each equation started and ended.
J = Justin
A = Ava
E = Emma
J = A + 7.50
E = J - 12
E + J + A = 63
E = A + 7.50 - 12
A + A - 4.5 + A + 7.50 = 63
3A = 60
A = $20
J = $27.50
E = $15.50
Given :
- An angle which measures 26.8° less than the measure of its complementary angle.
⠀
To Find :
- The measure of each angle.
⠀
Solution :
- Let's assume the one of the complementary angle as "x" and the other angle as (x – 26.8)° .
⠀
Now,
⠀
According to the Question :
⠀
⠀
⠀
⠀
⠀
⠀
⠀
⠀
Therefore,
- Other angle = 58.4° – 26.8° = 31.6°
⠀
Hence,
- The measure of the each angles are 58.4° and 31.6° .
