Hi there,
1)
6 + (w - 10) = 5
6 + w - 10 = 5
- 4 + w = 5
w = 5 + 4
Hence, W = 9
2)
2/3 + y - 1/9 = 7/9
5/9 + y = 7/9
y= 7/9 - 5/9
Hence, Y = 2/9
4)
4x - 3/2x - 15/4 = 3/8
32x - 12x - 30 = 3
20x - 30 = 3
20x = 3 + 30
20x = 33
Hence, the answer is 33/20
5)
0.7(3s + 4) - 1.1s = 7.9
2.1s + 2.8 - 1.1 = 7.9
s + 2.8 = 7.9
s = 7.9 - 2.8
Hence, the answer is 5.1
Hope this all helps :)
Answer:
Step-by-step explanation:
Given the fraction
Multiplying numerator and denominator by 5
Therefore,
Similarly,
Given the fraction
Multiplying numerator and denominator by 2
Therefore,
The reciprocal is just the fraction flipped over. 7/6 flipped is 6/7.
A: -5/18
B:1 and 16/35
C: 7/30
D: 7/8
B is right:
because it is -2 will make it 0 so it is two unit to the left.
