Answer:
-4.6 ft
Step-by-step explanation:
We need to learn to extract only the necessary information to answer question. The surf shop and the restaurant is extra information.
Monday 1 pm 2.2 ft
Monday 7 pm - 2.4 ft
Net change
-2.4 ft - 2.2 ft = -4.6 ft
The ocean went down 4.6 ft from 1 pm to 7 pm on Monday
Answer:
x = 9
Step-by-step explanation:
1) Subsitute! You have to replace y with 2x - 2 in 3x -y = 7, b/c they already gave you the equation for y (in the second part: y = 2x - 2)
So, your equation would look like this : 3x - (2x - 2) = 7
3) Solve suing PEMDAS!
There's a negative outside the parenthesis of 2x -2 -> - (2x-2). Multiply the negative individually inside the parenthesis so you will get (-2x + 2)
3x - 2x - 2 = 7 subtract the same variable; x
1x - 2 = 7 you don't need to put 1 to x, only if you want!
+ 2 + 2 add 2 on both sides
x = 9
I think it’s A or D I think one of them
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
