Answer:

Answer is "B"

Step-by-step explanation:

Rearrange terms: 7-2x=9x+19

-2x+7=9x+19

Subtract 7 from both sides of the equation: -2x+7=9x+19

-2x+7-7=9x+19-7

Simplify: -2x=9x+12

Subtract 9x from both sides: -2x=9x+12

-2x-9x=9x+12-9x

simplifiy: -11x=12

solution: x=-12/11

Answer:

Step-by-step explanation:

A half rest is 2 beats, a quarter rest is 1 beat, so the rests on the left total 3 beats.

The half note on the right is normally 2 beats, but the dot adds half-again that amount, so 1 more beat. The dotted half note on the right is 3 beats.

Both represent 3 beats, so their beat counts are "equal."

Keith is trying to construct triangle ABC. Which measures will determine unique triangles

BlackZzzverrR [31]

Answer:

When Three sides of the triangle are known

Two sides of the triangle is known and corresponding angle is included
Two angles known and their included side given
Two angles known and the length of a non included side is given

Step-by-step explanation:

The measure that will determine a unique triangle are

when Three sides of the triangle are known

Two sides of the triangle is known and their corresponding angle is included
Two angles known and their included side given
Two angles known and the length of a non included side is given

unique triangles are termed unique because they can be drawn only using one way

Really easy math question

Eddi Din [679]

Number of sodas sold = 130

Number of hot dogs sold = 65

Step-by-step explanation:

Given,

Combined number of sodas and hot dogs sold = 195

Let,

x represent the number of sodas sold

y represent the number of hot dogs sold

According to given statement;

x+y=195 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$2y+y=195\\3y=195$

Dividing both sides by 3

$\frac{3y}{3}=\frac{195}{3}\\y=65$

Putting y=65 in Eqn 2

$x=2(65)\\x=130$

Number of sodas sold = 130

Number of hot dogs sold = 65
