-4ỿ = 8
Simplify the left side in order to isolate the ỿ!
-4ỿ = 8
+4 +4
Ỿ = 12
⓶
× + 3y - 3z = -26
Simplify the left side in order to isolate the ×, ỿ and z!
× + 3y - 3z = -26
÷3 ÷3
× + ỿ - 3z = -8,66 periodic
÷-3 ÷-3
× + ỿ + z = 2,88 periodic
⓷
2× - 5ỿ + z = 19
Simplify the left side in order to isolate the ×, ỿ and z!
2× - 5ỿ + z = 19
÷2 ÷2
× - 5ỿ + z = 9,5
÷-5 ÷-5
× + ỿ + z = -1,9
9.80 / 20 = 0.49. Justin payed $0.49 per pound. :P
Answer:
570 miles
Step-by-step explanation:
304/4 is how many miles it travels in each hour and if its 7.5 hours then you multiply that by each mile it takes each hour.
304/4 = 76
76 x 7.5 = 570
X = 4(180 - x)
x = 720 - 4x
4x + x = 720
5x = 720
x = 720/5
x = 144
180 - x =
180 - 144 =
36
the measure of the angle is 144...the measure of its supplement is 36
Answer: n⁴+10n²x+25x²
Step-by-step explanation:
I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.
(n²+5x)² [rewrite this from the squared]
(n²+5x)(n²+5x) [use FOIL to expand]
n⁴+5n²x+5n²x+25x² [combine like terms]
n⁴+10n²x+25x²
