X = 0 y = 15(0) - 4 = -4
x = 1 y = 15(1) - 4 = 11
x = 2 y = 15(2) - 4 = 26
x = 3 y = 15(3) - 4 = 41
x = 4 y = 15(4) - 4 = 56
x = 5 y = 15(5) - 4 = 71
range = largest - smallest
71 - -4 = 75
so the range is 75
Answer:
Step-by-step explanation:
The correct answer is not the first answer, but the second answer in the middle. The third answer is the correct one because, since it has the correct exponent, that is, 0.51 grams.
_________________________________________________________
The approximate total mass is the number of atoms multiplied by the weight of an atom.
The approximate overall mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom) which is equivalent to a mass of 0.51 grams. (1.67 10⁻²⁴ grams/1 atom) = 0.51102 g ≈ 0.51 g
Answer: B. 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1
Answer:
<em>start with y</em>
y
<em>add 7</em>
y+7
<em>multiply by 3</em>
3(y+7)
<em>subtract 6</em>
3(y+7)-6
<u>therefore the answer is:</u>
3y + 21 - 6
=
3y + 15 or 3(y+5)
Answer:
20 and 25.
Step-by-step explanation:
Given:
They both teach total 45 yoga classes each week.
Erica teaches 15 fewer than twice as many as Bo.
To find:
How many classes does each instructor teach per week = ?
Solution:
Let number of classes are taken by Bo = 
Then number of classes are taken by Erica =
(given)
Total number of classes are taken by both = 45 (given)
According to the question.
+
= 45

By adding both side by 15

By dividing both side by 3

number of classes are taken by Bo =
= 20
number of classes are taken by Erica = 
= 
Therefore, number of classes are taken by Bo and Erica is 20 and 25.
