Answer:
3*( 8-2n)=5n
The number is 24/11
Step-by-step explanation:
three times
3*
the difference of eight and twice a number
3*( 8-2n)
is five times the number
3*( 8-2n)=5n
To solve
Distribute
3*8 -3*2n = 5n
24 -6n = 5n
Add 6n to each side
24 - 6n +6n = 5n +6n
24 = 11n
Divide each side by 11
24/11 = 11n/11
24/11 =n
The number is 24/11
Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
We spread the a to the 2x and -3 first,
2ax -3a= bx+5 5ax
By adding 3a, we pass the -3a over
2ax=bx+5+3aa bx+5+3aa
We'll pass the bx over the bx, then
2ax-bx=5+3aa-bx=5
Now we will party like this on the left side,
5+3a) x(2a-b)=5+3a)
Everything we have to do to find x is to separate both sides by (2a-b)
x=(3a+5)/=(3a+5)/ (2a-b)
The expression (2⁴)⁻¹ is simplified as one over two raised to the fourth power. Then the correct option is B.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ (2⁴)⁻¹
We know that a⁻ⁿ = 1 / aⁿ, then the value of the expression is given below.
⇒ 1/ (2⁴)
The expression (2⁴)⁻¹ is simplified as one over two raised to the fourth power. Then the correct option is B.

Answer:
20 Tshirts
Step-by-step explanation:
Tshirts = $7.90 each
Shipping = $2
Total amount = $160
Amount of tshirts bought = y
7.90y + 2 = 160
7.90y = 160 -2
7.90y = 158
Divide both sides by 7.9
y = 158÷7.9
y = 20
