Answer: That number is 16.
Step-by-step explanation:
n + 7 = 2n- 9 n represents the number now solve the question
+ 9 +9 add 9 to both sides
n + 16 = 2n subtract n from both sides
-n -n
16= 1n Divide both sides by 1
n= 16
Check: 16 + 7 = 2(16) - 9
23 =23
Ratio and prooprtion
scale:actualdistance=5in:29mi
so
5:29=?:87
5/29=?/87
times both sides by 87
435/29=?
15=?
they would be 15in apart
(3.7 x 104)2 = 769.6
In Scientific notation:
7.696 x 10^2
Answer:
x = -7
Step-by-step explanation:
<u>Step 1: Distribute</u>
1/3(24x - 54) = 11(x - 4) + 5
8x - 18 = 11x - 44 + 5
<u>Step 2: Solve for x</u>
8x - 18 = 11x - 44 + 5
8x - 18 - 11x + 18 = 11x - 39 - 11x + 18
-3x / 3 = -21 / 3
x = -7
Answer: x = -7
