Answer:

$infinitely \: many \: solution$

Step-by-step explanation:

1) Cancle -60 on both sides.

$5x = 2x + 3x$

2) Simplify 2x + 3x to 5x.

$5x = 5x$

3) Since both sides are equal, there are infinitely many solutions.

$infinietly \: many \: solution$

Therefor, this equation has infinitely many solutions.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y + 5x = 1

5y - x = 5

Step 2: Rewrite Systems

y + 5x = 1

Subtract 5x on both sides: y = 1 - 5x

Step 3: Redefine Systems

y = 1 - 5x

5y - x = 5

Step 4: Solve for x

Substitution

Substitution in y: 5(1 - 5x) - x = 5
Distribute 5: 5 - 25x - x = 5
Combine like terms: 5 - 26x = 5
Isolate x term: -26x = 0
Isolate x: x = 0

Step 5: Solve for y

Define equation: 5y - x = 5
Substitute in x: 5y - 0 = 5
Subtract: 5y = 5
Isolate y: y = 1

The dance committee of Pine Bluff Middle School earns \$72$72dollar sign, 72 from a bake sale and will earn \$4$4dollar sign, 4

Brut [27]

Answer:

The correct answer is 72 + 4 × x $\geq$ 400.

Step-by-step explanation:

The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.

The dance will cost $400.

Let x number of tickets the committee could sell.

Total money earned is 72 + 4 × x.

The committee should have some left over money also after spending for the dance which costs $400.

Thus the inequality to determine the number of tickets the committee could sell to have money left over after they pay for this year's dance is given by,

72 + 4 × x $\geq$ 400.
