2.34 x 10 to the 9th power i think
Answer:
7/8 > 3/4 > 1/2
Or
1/2 < 3/4 < 7/8
Step-by-step explanation:
Given 7/8, 3/4, and 1/2
We need to make the numbers in order from the least to the greatest or from the greatest to the least
The easy method is convert the rational numbers to decimal numbers
So,
7/8 = 0.875
3/4 = 0.75
1/2 = 0.5
So, the numbers form the least to the greatest are:
0.5 , 0.75 , 0.875
So,
1/2 , 3/4 , 7/8
The inequality correctly compares the numbers are:
1/2 < 3/4 < 7/8
Or can be written from the greatest to the least as:
7/8 > 3/4 > 1/2
Answer:
1/6.
Step-by-step explanation:
x / 4/7 = 7/24 where x is the dividend.
7x/4 = 7/24
Cross multiply:
7x * 24 = 4*7
x = 28/(7*24)
= 28/168
= 1/6.
Answer:
15 y 8
Step-by-step explanation:
y = x - 7
x² + y² = 289
sustituir: x² + (x - 7)² = 289
distribuir: x² + x² - 14x + 49 = 289
sustraer + simplificar: 2x² - 14x - 240 = 0
dividir: x² - 7x - 120 = 0
x² - 15x + 8x - 120 = 0
(x - 15)(x + 8) = 0
x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales
sustituir: y = 15 - 7
simplificar: y = 8
