Answer:Combine like terms

−

{\color{#c92786}{3x}}+5{\color{#c92786}{-x}}=9x-7+12

3x+5−x=9x−7+12

−

{\color{#c92786}{2x}}+5=9x-7+12

2x+5=9x−7+12

Add the numbers

Subtract the same term from both sides of the equation

Simplify

Subtract the same term from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify

List the angles in triangle QRS from smallest to largest.

Answer:

angle R

Step-by-step explanation:

To solve this we will use cosine rule

Cosine rule

cos(A) = $\frac{b^{2}+c^{2}-a^{2}}{2bc}$

suppose,

q = 6.25

s = 11.04

r = 13.19

angleQ = $cos^{-1}(\frac{13.19^{2}+11.04^{2}-6.52^{2}}{2(13.19)(11.04)})$

= 30.58

angleR = $cos^{-1}(\frac{6.52^{2}+11.04^{2}-13.19^{2}}{2(6.52)(11.04)})$

= 93.82

angleS = $cos^{-1}(\frac{6.52^{2}+13.19^{2}-11.04^{2}}{2(6.52)(13.19)})$

= 56.63

The value of x is 14

<h3>How to solve for x?</h3>

From the question, the lines from the center of the circle to the chords have equal measures of 9 units

This line divides a chord into equal segments, where each segment is 7 units

So, we have:

x = 7 + 7

Evaluate

x = 14

Hence, the value of x is 14

Trisha had the following seven distances (in feet) in the triple jump.

butalik [34]

The range of a data set is the greatest value minus the smallest value.

The greatest value here is 32, and the smallest value is 27:

$\sf Range=32-27=\boxed{\sf 5}$
