Answer:

7

Step-by-step explanation:

We have the expression 3n - 5, which we know the value of n is 4. We are asked to solve.

Since we know that n = 4, we can substitute 4 with n in the expression :

3(4) - 5

12 - 5

Help me please if you know,Thanks

The answer would be B because if you divide 12 by 8 that will give you the rate. 12÷8=1.5 Then you just need to multiply the rate by 70. 1.5 * 70 = 105

The line that contains the point Q( 1, -2) and is parallel to the line whose equation is y - 4 = 2/3 (x - 3)
Musya8 [376]

Answer:

y + 2 = \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = \frac{2}{3}(x - 3) ← is in point- slope form

with slope m = \frac{2}{3}

Parallel lines have equal slopes, thus equation of parallel line

with m = \frac{2}{3} and (a, b) = Q(1, - 2) is

y - (- 2) = \frac{2}{3}(x - 1) , that is

y + 2 = \frac{2}{3}(x - 1)

In ADP + pi=ATP, what does pi stand for?
Alinara [238K]
This is not a math question. It's a biology question.

ADP stands for A<span>denosine diphosphate
ATP stands for </span><span>Adenosine triphosphate

ADP has only 2 phosphate ions while ATP has 3.

ADP + pi = ATP

pi stands for phosphate ion.

2pi + pi = 3pi
