Answer:

See below

Step-by-step explanation:

$2e)15-4x=10x+45$

Solve:

$15-4x=10x+45\\-4x-10x=45-15\\-14x=30\\ \boxed {x=-\dfrac{15}{7}}$ $3(x+1)=21$

Check:

$15-4 \left(-\dfrac{15}{7} \right)=10\left(-\dfrac{15}{7} \right)+45$

$15+\dfrac{60}{7} \right)=-\dfrac{150}{7} +45$

$\dfrac{210}{7} =30$

$30=30$

$3a) 3(x+1)=21$

Solve:

$3(x+1)=21\\3x+3=21\\3x=18\\x=6$

$3b) 2+3(x+1)=6x$

$2+3x+3=6x\\5=3x\\$

$x=\dfrac{5}{3}$

$3c) -2(2x-3)=-2$

Solve:

$-2(2x-3)=-2\\-4x+6=-2\\-4x=-8\\x=2$

Round 4.675 to the nearest cent

Viktor [21]

Money is written out to the hundredths place, so when rounding to the nearest cent, round to the hundredths place. In 4.675, the 7 is in the hundredths place. The value to its right, 5, is greater than 4, so the 7 is rounded up to 8. So 4.675 to the nearest cent is 4.68

How many km are equal to 3,400 m

1 km = 1000 m

So

x km = 3,400 m

that means 3.4 km would be equal to 3,400 m

your final answer is

$\boxed{\bf{3.4~km}}$
