Let 'x' be the initial weight of Hamid.
He gained 0.10x kg (10% of his first weight)
His current weight:
0.10x + x = 88
1.10x = 88
x = 88/1.10
x = 80 kg

20 ÷ (5x2/5) + 3 help please​
vlabodo [156]

Answer:

13

Step-by-step explanation:

hey take a deep breath! you got this!

it's really simple if you use the format PEMDAS

P- parentheses

E-exponents

M-Muliplication

D-divison

A-addition

S-subtraction

or mostly used

P

E

M or D

A or S

(depends from which side just start Ex 2-1+8 you wouldn't do the plus first but the subtraction because we're going left to right. If it's 2x8-6+10 then we do multiplication first cause that step comes first, the minus then addition! hope that isn't to confusing!)

ok so our equation is 20÷(5x2/5)+3

whats our first step? remember PEMDAS!

Its Parenthesis! so first we do the equation (5x2/5)

since multiplication and division are in the same "category" we go left to right

so first we do 5x2=10 and then we do 10/5 which is equal to 2!

ok now we add back the rest of our equation!

20÷2+3 since we already solved the Parenthesis

now what come first? division or addition?

its division because.. once again... PEMDAS!!

So now we do 20÷2 which is equal to 10!

now whats left is to add 3!

and 10+3 is equal to .... 13!!!

I know it seems like a lot but you'll get the hang of it! just take it easy and take your time :)

Which expression is equivalent to (5^√3^2)^1/3 ?
kiruha [24]

Answer:

\frac{-177}{286}

Explanation:

Given,

\left(\frac{3}{11}\times\frac{5}{6}\right)-\left(\frac{9}{12}\times \frac{4}{3}\right)+\left(\frac{5}{13}\times \frac{6}{15}\right)

ft(\frac{5}{22}\right )-\left(\frac{36}{36}\right)+\left(\frac{2}{13}\right)

{5}{22}\right )-1+\left(\frac{2}{13}\right)

{5\times 13-286+2\times 22}{286}

{65-286+44}{286}

{109-286}{286}

{-177}{286}
