2.6x3 1/3= 8.666
Hope this helps :)
4x - 10 = 34
4x +10 +10
4x = 44
4x/4 = 44/4
x = 11
Answer:
x = 3/2
Step-by-step explanation:
(2x + 3)2 – 4(2x + 3) - 12 = 0
Simplify the equation then isolate for x.
Distribute over brackets:
(4x + 6) – (8x + 12) - 12 = 0
Combine like terms:
4x + 6 – 8x + 12 - 12 = 0
6 - 4x = 0
Isolate x:
6 = 4x
6/4 = x
Reduce the fraction:
6/4 = x <= divide top and bottom by "scale factor" of 2
3/2 = x
x = 3/2 <= having x on the left side is standard
Answer:
PQR=133°
Step-by-step explanation:
PQR+RQS = 180
(3x -5)+(x+1)=180
4x -4=180
4x =180+4
4x =184
x=184/4
x=46
PQR= 3x-5=3(46)-5=138-5=133
I hope I helped you^_^
Answer:
193.8
Step-by-step explanation:
a = 3.8 times 10^13 = 38,000,000,000,000
b = 5.1 times 10^-12 = 0.0000000000051
a times b = 193.8
