Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
<u>check</u>
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
we know there are 9 dashes between 0 and 0.5. meaning each place represents 0.05 apart.
0_0.05_0.10_0.15_0.20_0.25_0.30_0.35_0.40_0.45_0.5
k is between 0.10 and 0.15
L is between 0.15 and 0.20
M is between 0.30 and 0.35
N is between 0.40 and 0.45
1/3 as a decimal is normally .3333 repeating
meaning M is the best answer
c. M
You have to find the common denominator which is 45. 4x9=36 5x9=45 which means 36 over 45. Then 8x5=40 9x5=45 which means 40 over 45. Add the numerators: 36+40= 76. So the answer is 76/45 and the decimal form is 1.68
