Answer:

x ≤ $\frac{19}{4}$

Step-by-step explanation:

Given

$\frac{x-1}{3}$ - 2 ≤ $\frac{5-2x}{6}$

Multiply through by 6 to clear the fractions

2(x - 1) - 12 ≤ 5 - 2x ← distribute and simplify left side

2x - 2 - 12 ≤ 5 - 2x

2x - 14 ≤ 5 - 2x ( add 2x to both sides )

4x - 14 ≤ 5 ( add 14 to both sides )

4x ≤ 19 ( divide both sides by 4 )

x ≤ $\frac{19}{4}$

5x-6y=-8 solve the equation

Setler79 [48]

Answer:

<u>Solved for y:</u> $y = 4/3 + 5/6x$

<u>Solved for x:</u> $x = 6/5y - 8/5$

Step-by-step explanation:

Solving for y

<u>Step 1: Subtract 5x from both sides</u>

$5x - 6y - 5x = -8 - 5x$

$-6y = -8 - 5x$

<u>Step 2: Divide both sides by -6</u>

$-6y / -6 = (-8 - 5x) / -6$

$y = 4/3 + 5/6x$

Solving for x

<u>Step 3: Add 6y to both sides</u>

$5x - 6y + 6y = -8 + 6y$

$5x = 6y - 8$

<u>Step 4: Divide both sides by 5</u>

$5x / 5 = (6y - 8) / 5$

$x = 6/5y - 8/5$

Bob has 6 more times than quarters. He has $1.65 in all. How many coins of each type does he have?

mrs_skeptik [129]

Answer:

3 quarters 9 dimes

Step-by-step explanation:

D=dimes

D-6=quarters

0.10 D + 0.25(D-6) = 1.65

0.10D + 0.25D - 1.5 = 1.65

0.35D = 3.15

Dibide both sides by 0.35

D =9

Q= D-6 Q = 9-6 Q=3

9*0.10 =90 3*0.25= 0.75

$0.75 + $0.90 =$ 1.65
