<span>Simplifying g(r) = -5r + 13 Multiply g * r gr = -5r + 13
Reorder the terms: gr = 13 + -5r Solving gr = 13 + -5r
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Divide each side by 'r'. g = 13r-1 + -5
Simplifying g = 13r-1 + -5 Reorder the terms: g = -5 + 13r<span>-1</span></span>

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8. <br><br> Simplify Q + S - T.

Butoxors [25]

$Q+S-T=7m+3n+n+5-(-m-3n+8)\\
Q+S-T=7m+4n+5+m+3n-8\\
Q+S-T=8m+7n-3$

Your meal cost $72.15 including the 11% tax. What was the original cost of your meal before tax?

Amiraneli [1.4K]

Multiplying 72.15 by .11 or 11% gives you 7.94 - this is the tax taken.
so just subtracting that from 72.15 gives you $64.21 as your answer.

In ΔJKL, the measure of ∠L=90°, JL = 80, KJ = 89, and LK = 39. What is the value of the sine of ∠J to the nearest hundredth

emmainna [20.7K]

Given:

In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.

To find:

The value of sine of ∠J.

Solution:

In a right angle triangle,

$\sin\theta =\dfrac{Perpendicular}{Hypotenuse}$

In triangle JKL,

$\sin J =\dfrac{LK}{KJ}$

$\sin J =\dfrac{39}{89}$

$\sin J =0.4382$

$\sin J \approx 0.44$

Therefore, the value of sine of ∠J is about 0.44.
