What is the value of x in y=3x-5 and 6x+3y=15

1 answer:

7 0

X=2

You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x

Then you make it one equation: 3x-5=5-2x

Third step is add the -2x with the 3x which is will be 5x.

Fourth: your new equation will be 5x-5=5

Next u would add 5 plus which is 10

Lastly your new equation is 5x=10

I honestly hope this helps !!!!

Q + 5/9= 1/6 from big ideas mathbook

Alika [10]

9We have such eqation
Q $+ \frac{5}{9} = \frac{1}{6}$ /*9 (multiply both sides by 9)
9Q+5= $\frac{9}{6}$ /-5 both sides
9Q= $\frac{9}{6}- 5$
9Q= $\frac{9}{6}- \frac{5*6}{6}$
9Q= $\frac{9-30}{6}$
9Q=- $\frac{21}{6}$ /:9 divide both sides by 9
Q=- $\frac{21}{6}:9$
Q $\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}$ - its the answer

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people."

nikklg [1K]

Answer:

112%

Step-by-step explanation:

The percentage of its capacity is calculated as

Number of people / Maximum Occupancy × 100%

Number of people = 84 people

Maximum Occupancy = 75 people

Hence:

84 people /75 people × 100

= 1.12 × 100

= 112%

Therefore, the percentage of its capacity that is 84 people is 112 %
