Insert one pair of brackets only to make the following statement correct 6 +5*10-8=16
jeka94

Answer:

6+5*(10-8)=16

Step-by-step explanation:

Using BODMAS multiplication takes precedence over addition and subtraction so as it stands it would be calculated as 6 + (5*10) - 8. To get the answer 16 it would be 6 + 5(10 - 8) Solving the brackets first, this gives 6 + (5*2) which gives 16.

uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

Speed=\frac{distance}{time}

in this problem

Speed=\frac{y}{x}

y=(Speed)*x

<u>Equation First Train</u>

y1=70x

<u>Equation Second Train</u>

y2=80x

y1+y2=600\ miles ---------> equation 1

Substitute the values of y1 and y2 in the equation 1

70x+80x=600

Solve for x

150x=600

x=4\ hours
