3n-3/5=3n-2/8 (The slashes are fraction bars, could i also have the steps?)

Drupady [299]

3n - $\frac{3}{5}$ = 3n - $\frac{2}{8}$ <em>convert fractions to decimals</em>

3n - 0.6 = 3n - 0.25 <em>subtract 3n from one side</em>

-0.6 = -0.25

-0.6 ≠ -0.25

Hope that helps!

Samaia buys two water bottles and three bags of chips for $9.45. Abdullah goes to the same store and buys four water bottles, as

kow [346]

Answer:

B) 2w + 3c = 9.45 AND 4w + 5c = 14.75

Step-by-step explanation:

Let us represent:

Number of water bottles = w

Number of bag of chips = c

Hence:

Samaia buys two water bottles and three bags of chips for $9.45.

2w + 3c = 9.45......Equation 1

Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75.

4w + 5c = 14.75......Equation 2

Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario?

Option B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 is the correct option.

5. Given that a + b = 8 and ab = 15, find the value of (a+b)² and a² + b²

Maksim231197 [3]

Answer:

64 and 34

Step-by-step explanation:

Given

a + b = 8 ( square both sides )

(a + b)² = 8² = 64

------------------------------------------------

(a + b)² = 64 ← expand left side

a² + b² + 2ab = 64 ← substitute ab = 15

a² + b² + 2(15) = 64

a² + b² + 30 = 64 ( subtract 30 from both sides )

a² + b² = 34
