Multiply in parenthesis: 2*5c and 2*-7
10c -14 =1
Plus 14 to each side.
10c = 15
Divide ten from each side.
C = 1.5

I hope this helps!

6x – 3y = 8
Nat2105 [25]

Answer:

Step-by-step explanation:

<em>The linear equation where:</em>

\large \boldsymbol {}  \sf y=\underbrace{m}_{slope }x \ +\underbrace{b} _{y -intersept}

Solution :

\displaystyle \sf \#13. \\\\   6x-3y=8 \\\\\ -3y=8-6x \\\\y=-\frac{8-6x}{3}  \\\\ \boxed{\sf y=2x-2\frac{1}{3} }} \\\\ slope =2 \\\\ y-intersept  =-2\frac{1}{3} \\\\-------------      

 \sf \#14 . \\\\\\ 7x=5y+2 \\\\5y=7x-2 \\\\y =\dfrac{7x-2}{5}  \\\\ \boxed{\sf y=1,4x-0,4} \\\\slope = 1,4 \\\\y-intersept  =-0,4 \\\\---------------  

    \dispalystye \sf \#15. \\\\ -6y+4x=8  \  |\div2 \\\\-3y+2x=4 \\\\ y=-\dfrac{4-2x}{3}  \\\\ y=\boxed{\sf \frac{2x-4}{3} } \\\\slope = \dfrac{2}{3}  \\\\ y-intersept  = -\dfrac{4}{3 }\\\\ -----------------

\sf \#16   .\\\\ x+y=2x+3 \\\\y=2x-x+3 \\\\\boxed{\sf y=1\cdot x+3}  \\\\slope =1 \\\\y-intersept =3

What is the probability that a random selected student at harbor high is 17 years old or older.
Triss [41]

Answer:

See below.

Step-by-step explanation:

The table shows the total number of students as 572 (bottom right cell in the table.)

The number of students who are 17 or older are the students in the two groups: 17-18 and 19-20.

There are 151 students with ages 17-18.

There are 34 students with ages 19-20.

The total of all students 17 or older is 151 + 34 = 185.

The probability of choosing a student age 17 or older is the number of students 17 or older (which is 185) divided by the total number of students (which is 572).

p(17 or older) = 185/572 = 0.3234 = 32.34%

We round 32.34% to the nearest integer to get 32%.

Which equations show you how to find 16-9?
Setler79 [48]
I think it might be B
because from 9+1 = 10 we can change to 9=10-1
and 10+6=16 no need to change
then we solve the problem with the equation
16 - 9
10+6 - (10-1)
10+6-10+1
7
thats the answer
