Answer:
id say the property is substitution
Step-by-step explanation:
i think substitution because youre substituting 7 for q so then the problem reads: -8(7)=-56
Answer:50 x 30 = 1500
50 x 6 = 300
30 x 1 = 30
6 x 1 = 6
Step-by-step explanation:
X = -2
learn this, it helps
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number
so x = -2.......is a vertical line which has an undefined slope <=
Answer:
The sum =105
Step-by-step explanation:
It is given that, finite sequence 3, 7, 11, ..., 27.
<u>Points to remember</u>
1). For a finite sequence sum of n term is given by
Sum = n/2[first term + last term]
2). nth term of of an AP
tₙ = a + (n - 1)d
Where a - First term
d - common difference
<u>To find the number of terms in the given sequence</u>
Here a = 3 and d = 7 - 3 = 4
tₙ = a + (n - 1)d
27 = 3 + (n - 1)*4
4(n -1) = 27 - 3 = 24
n - 1 = 24/4 = 6
n = 6 +1 =7
<u>To find the sum</u>
Sum = n/2[first term + last term]
= 7/2[3 + 27]
= 7/2[30] = 7 * 15
= 105
