For number 2 you would need to divide 30 by 6 so 30/6 which equals 5. For number three the answer is 23.
Answer:
d = 5
Step-by-step explanation:
-7d = -35
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, d. Divide - 7 from both sides:
(-7d)/-7 = (-35)/-7
d = -35/-7
d = 35/7
d = 5
d = 5 is your answer.

The equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.
<h3>What is linear function?</h3>
Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
y=mx+c
Here, m is the slope of the line represented by the function and c is the y intercept.
The equation given in the problem are,
2ry+y= 9
y=12r-5
3y+r2+t=0
4r+2(y-1)=0
The second option is similar to the standard linear function.
Hence, the equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.

Answer:
2.05
Step-by-step explanation:
Answer:
AB = 8
Step-by-step explanation:
AC = 36
AB/BC = 2/7
AB = (2/7)BC
AB + BC = 36
(2/7)BC + BC = 36
(9/7)BC = 36
BC = 36(7/9)
BC = 4*7
BC = 28
AB + BC = 36
AB = 36 - 28
AB = 8
======
Is AB/BC = 2/7?
8/28 = 2/7 YES
