Answer: 450 km.

Step-by-step explanation: To find the answer to this question, you have to use unit multipliers. We know that 1 cm on the map is 50 km in real life so we multiply 50 km / 1 cm by 9 cm. This cancels out the cm, making km the units. 50*9 = 450, so the answer is 450 km.

X + (2x + 5) = 3(x – 4)+7

eduard

Answer:

Not true

Step-by-step explanation:

x + (2x + 5) = 3(x – 4)+7

Opening bracket on left and side and distributing 3 over (x-4) on right hand side

x+2x+5=3x-3 x 4 + 7

adding like terms

3x+5=3x-12+7

3x+5=3x-5

Hence

5 = -5

Which is not possible , Hence the equation given to us is false.

V-9/10v+6=11(hlp)this problem is confusing.

Valentin [98]

$\frac{v-9}{10v+6}=11 \\\\ 11(10v+6)=v-9 \\\\ 110v+66=v-9 \\\\ 110v-v=-9-66 \\\\ 109v= -75 \\\\ \boxed{v=-\frac{75}{109}}$
