T=2n+3
considering n has no other values given
Answer:
z=-7
Step-by-step explanation:
-9+8*14z+8*2=7*17z+7*8
-9+112z+16=119z+56
112z+7=119z+56
-112z -112z
7=7z+56
-56 -56
-49=7z
:7 :7
z=-7
Answer:
6.75 × 10^3
Step-by-step explanation:
Move the decimal 3 times to the left so that the resulting number, m = 6.75, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 3
Write in the scientific notation form, m × 10^n
6.75 × 10^3
Answer: x = 4
Step-by-step explanation:
We'll call the number "x."
"Twice the difference of a number and 3" means 2(x-3)
is equal to 2: =2
Put them together:
2(x-3) =2
2x - 6 = 2
2x = 8
x = 4
Check:
2(x-3)
Twice the difference of a number and 3 is equal to 2
2(4 - 3) = 2 ?
<h2>2(1) = 2 <u>
Yes</u></h2>
7/8 = 87.5%
I'm guessing it is meant to say round to the nearest 10th of a percent
If the question actually says something different comment so i can fix it
