Julia’s score is <em>y</em> and Tina’s score is <em>y</em> + 6.

Step-by-step explanation:

Let us take Julia’s score be <em>y</em>.

First Tina scored 4 points more than Julia, so the expression is <em>y</em> + 4.

Then, Tina earned 2 points as extra credic, now the expression becomes

(y + 4) + 2 = y + 6.

Hence Julia’s score is <em>y </em>and Tina’s score is <em>y</em> + 6.

<span>Simplifying 2x + 18y = 36 Solving 2x + 18y = 36 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-18y' to each side of the equation. 2x + 18y + -18y = 36 + -18y Combine like terms: 18y + -18y = 0 2x + 0 = 36 + -18y 2x = 36 + -18y Divide each side by '2'. x = 18 + -9y Simplifying x = 18 + -9y</span>

Threatened monarch butterflies are monitored by measuring the area occupied by overwintering butterflies in Mexico. According to
Pani-rosa [81]

Answer:

14.2 hectares

Step-by-step explanation:

Fund Mexico, monarch butterflies occupied 1.13 hectares one recent winter, and 4.01 hectares the following winter (one year later)

The formula of Geometric growth

(Pt/ Po)^1/t

Where Pt = Size after t years = 4.01 hectares

Po = Initial size = 1.13

t = times = 1

=( 4.01/1.13 )^1/1

= 3.5486725664

Hence, Geometric growth rate = 3.5486725664.

It's size in hectares after another 1 year = Current size in hectares × Geometric growth rate

= 4.01 ×3.5486725664

= 14.230176991 hectares

≈ 14.2
