What the answer to 1/3 + (2/3 + 5/8)?

exact form : 13/8

decimal: 1.625

mixed number: 1 5/8

1 5/8 .  or 39/24

Step-by-step explanation:

Start with the numbers in the brackets

2/3 + 5/8

Use the LCM, which is 24

Multiply the numerators by the numbers which are used to multiply the denominators to 24

16/24 + 15/24 = 31/24

Now return to the 1/3 outside the bracket

1/3 + 31/24

Multiply the numerator and denominator by 8

8/24 + 31/24 = 39/24

Either keep it as 39/24 or the mixed fraction 1 15/24 to 1 5/8

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
