A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

A spinner has four sections lettered A, B, C, and D. The table shows the results of several spins. Find the experimental probabi
Degger [83]
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35  Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)

Help me with #5 pleaseeeeeeeeeee

Answer:

\angle 1 = 45 degrees

Step-by-step explanation:

Sum of 3 angles in a triangle is 180..

The angles given are:

60

7x + 12

1

So we sum to 180 and write:

60+7x+12+\angle 1=180\\72+7x+\angle 1=180\\7x+\angle 1=108

Also, straight angle is 180 degrees, thus Angle 1 and (14x + 9) angle is sum to 180, thus we can write:

14x+9+\angle 1=180\\14x + \angle 1=171

Or we can write this as:

14x + \angle 1=171\\\angle 1 = 171 - 14x

We substitute this expression for Angle 1 into 1st equation we got and solve for x first,

7x+\angle 1 = 108\\7x+( 171 - 14x)=108\\-7x=-63\\x=9

Since x = 9, the angle "14x + 9" would be:

14(9) + 9 = 135

Hence Angle 1 would be:

\angle 1 + 14x + 9 = 180\\\angle 1 + 135 = 180\\\angle 1 = 45
