-4(x + 1) + 7x = 8
-4x - 4 + 7x = 8
3x - 4 = 8
3x = 8 + 4
3x = 12
x = 12/3
x = 4 <===
Answer:
sin Φ/(sin Φ + cos Φ) = 12/17
Step-by-step explanation:
sin Φ = 12/13
then sin Φ + cos Φ = 12/13 + 5/13
= 17/13
So , sin Φ/(sin Φ + cos Φ) = 12/13 ÷ 17/13
= 12/13 × 13/17
= 12/17
Answer:
<u>3/16 of the whole pie</u>
Step-by-step explanation:
Lexi had 3/4 of an apple pie. She gave 1/4 of it to Julie. That means what Julie receives is the product of the whole and the portion.
==========================================================
Solving :
Therefore, the equation is :
⇒ 3/4 × 1/4
⇒ <u>3/16 of the whole pie</u>
Answer:
n = - 12
Step-by-step explanation:
n + 6 = 2n/4
4 (n+6) = 2n
4n + 24 = 2n
4n - 2n = - 24
2n = -24
n = - 24/2
n = - 12
1 14'th as a decimal would be 1/14 or 0.0714 (rounded to the nearest ten thousandth)
