5(x+4)=45
5x+20=45
5x=25
x=5
Answer:
0.1,0.5,0.8,0.9
Step-by-step explanation:
−3/7×14/15×7/12×(−30/35)
=(−3/7×14/15)×(7/12×−30/35)
On further calculation, we get
=−2/5×−1/2
We get,
=1/5.
Property 1:
If a/b is a rational number and m is a non-zero integer then a/b =(a*m)/(b*m). In other words, we can say that the rational number remains unaltered if we multiply both the numerator and denominator with the same integer. Ex: 2/3 = 2*2/3*2 = 4/6, 2*3/3*3 = 6/9, 2*4/3*4 = 8/12.

2x - 5 = 7
2x = 7 + 5
2x = 12
2x/2 = 12/2
x = 6
to check:
2x - 5 = 7
2(6) - 5 = 7
12 - 5 = 7
7 = 7
