The 12th term = a + 11d where a is the first term and d is the common difference
a + 11d = 74
The first three terms are a, a + d, a + 2d
a + (a + d) + (a + 2d) = 42
3a + 3d = 42
a + d = 42 / 3 = 14
By subtracting this equation from the T12 equation
(a + 11d) - (a + d) = 74 - 14
10d = 60
d = 6 (the common difference = 6)
a + 6 = 14
a = 14 - 6 = 8 (the first term = 8)
S(n) = n/2 x (2a + (n-1)d)
S(10) = 10/2 x (2x8 + (10-1)x6)
S(10) = 5 x (16 + 54) = 5 x 70 = 350
Answer:
= 3oz
Step-by-step explanation:
v = 20mm ×150mm ×2mm = 6000 mm^3
so, the weight is
6000 mm^3 × 0 .0005oz/1mm^3 = 3oz
Answer:
15/5
Step-by-step explanation:
Answer:
Markia had 14 cookies.
Step-by-step explanation:
Let's represent the total amount of cookies as y.
We know that after she gave away 4 cookies and divided the remainder by 2, she had 5 cookies left.
This can represented as an equation.
= 5
To solve this equation we have to isolate the y.
= 5
Multiply both sides by 2 to isolate the y - 4: y - 4 = 10
Add 4 to both sides to isolate the y: y = 14
The total amount of cookies is 14.
