Divide 3 by for to get 0.75 but that is a fraction
Answer:
m > 4
Step-by-step explanation:
5m - 8 > 12
Add 8 to each side
5m - 8+8 > 12+8
5m > 20
Divide by 5
5m/5 > 20/5
m > 4
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1)
we know that
The perimeter of triangle is equal to the sum of its length sides
so

Part 2)
we know that
The area of triangle is given by the formula

we have

substitute

Answer:
1
Step-by-step explanation:
Factorise numerators/ denominators where possible
3x² - 4x + 1 = (x - 1)(3x - 1)
x² - 1 ← is a difference of squares and factors as
x² - 1 = (x - 1)(x + 1)
Expressing the product in factored form
× 
Cancel common factors on numerator/denominator, that is
Cancel (x - 1) , (x + 1) and (3x - 1), leaving the simplified form 1
Answer:
A. x = 7
B. x = -3
Step-by-step explanation:
A. 5/x = 30/42
5/x = 5/7
5 = 5/7 x
5= 5x/7
5 x 7 = 5x
35 = 5x
35/5 = x
7 = x
x = 7
B. x/8 = -12/32
x/8 = -3/8
x = - 3/8 x 8
x = - 24/8
x = -3
Hope this helps you have a gr8 day :3
