Step-by-step explanation:
5^2 + b^2 = 9^2
25 + b^2 = 81
b^2 = 56
square root both sides and b = 7.48 cm
Answer:
x = -
Step-by-step explanation:
Given
x + 2 =
Multiply through by 24 ( the LCM of 6 and 8 ) to clear the fractions
20x + 48 = 21 ( subtract 48 from both sides )
20x = - 27 ( divide both sides by 20 )
x = -
Answer:
4
Step-by-step explanation:
replace x with its value to get
8-2y+3y=12 then combine like terms
8+y=12 subtract 8 from both sides
y=4
Answer:
19
Step-by-step explanation:
You subtract 183 from 300 which gets you 117 which you then divide by 9 to get 13.
Answer:
y = 5x -3
Step-by-step explanation:
y = mx + b
b is the y intercept, so you can replace b with -3
m is the slope so you can replace m with 5
and you get your answer y = 5x - 3
