Step-by-step explanation:

x + y = 3 ---------------- eqn 1

y = -6x + 3 ------------- eqn 2

Substitute y for -6x + 3 in equation 1

x + -6x + 3 = 3

x - 6x + 3 = 3

-5x + 3 = 3

Collect like terms

-5x = 3 - 3

-5x = 0

Divide both sides by -5

x = 0

Answer:

36

Step-by-step explanation:

Pentagon has 5 sides

The formula for finding the sum of the measure of the interior angles is (n - 2) * 180

(5-2)×180= 3×180=540

To get each interior angles

540/5 = 108

180 -108 = 72

To get x

72+72+x= 180 (sum if angles in a triangle)

144+x= 180

x = 180 -144 = 36

2. x is part of the interior angles = 108

A florist arranges 4 flower arrangements in 92 minutes.
Black_prince [1.1K]

Answer:

\boxed {\boxed {\sf 9 \ arrangements }}

Step-by-step explanation:

Let's set up a proportion using the following setup:

\frac{arrangements}{minutes} =\frac{arrangements}{minutes}

We know that the florist can arrange 4 in 92 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{arrangements}{minutes}

We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{ x \ arrangements}{ 207 \ minutes}

\frac{4}{92} =\frac{x}{207}

Solve for x by isolating it on one side of the proportion.

x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.

207*\frac{4}{92}=\frac{x}{207}*207

207*\frac{4}{92}=x

207*0.0434782609=x

9=x

The florist can arrange <u>9 arrangements</u> in 207 minutes.
