Use the order of operations to solve 4[2.5 3(20 7)]

Mathematics

PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

4(2.53(207))

Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:

4(523.7)

Then, do multiplication again:

2094.8

So that means, 4(2.53(207)) = 2094.8

I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.

Write the formula to calculate how much dough is prepared in x hours.
spin [16.1K]

Answer: D(x) = 2kg/h*x

where x is the number of hours.

Step-by-step explanation:

The information that we have is:

in 5 hours, we can prepare 10kg of dough.

With this, we can find the rate per hour, to do this we find the quotient:

R = 10kg/5h = 2kh/h

This meeans that in one hour, we can make 2kg of dough.

Then, in x hours, we can make x times 2kg of dough, then the equation will be:

D(x) = 2kg/h*x

where x is the number of hours.
