3x^2 = 7x - 3
3x^2 - 7x = -3
x^2 - 7/3x = -1
x^2 - 7/3x + 49/36 = -1 + 49/36 = 13/36
(x - 7/6)^2 = 13/36
x - 7/6 = + or - sqrt(13)/6
x = 7/6 + or - sqrt(13)/6
x = (7 + or - sqrt(13))/6
Answer:
14x-56y-42
Step-by-step explanation:
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
14x-56y-42
Hence the equivalent expression is
14x-56y-42
Answer:
20 and 10
Step-by-step explanation:
Answer:
m = 7.25
Step-by-step explanation:
8m + 7 - 5 = 60
Evaluate like terms.
8m + 2 = 60
Isolate 8m.
8m = 60 - 2
Evaluate.
8m = 58
Find m.
m = 58 ÷ 8
m = 7.25
Answer:
y= 240
Step-by-step explanation:
let the angle of value 29° be called A
then Sin(A) = opposite side / hypotenuse
then Sin(A) = y / 500
by applying cross multiplication
y = 500×Sin(A)
sin(A)= sin(29) = 0.484809
then multiply by 500
it gives you 242.4048
rounding to the nearest tenth:
240
y= 240ft
