For the first part:

distance= speed * time
distance=6*45
=270

for the second part:

distance=speed*time
distance=7*45
=315

total-distance already traveled = distance left
850-315-270=265
distance left=265 miles

The answer is B.
Hope this helps! :)

Find three consecutive even integers such that 3 times the first is 26 less than twice the sum of the last two
Dimas [21]
Let's say our first integer is "a".

how to get the next consecutive EVEN integer?  well, just add or subtract 2 from it, therefore, the second consecutive integer will be "a + 2".

and the next after that, will then be (a + 2) + 2, or "a + 4".

so those are are 3 integers, a           a + 2           a+4

notice that, from any even or odd integer, if you hop twice either forwards or backwards, you'll land on another even or odd integer respectively.

2 + 2 is 4, or 8 + 2 is 10  some even ones

3 + 2 is 5, or 13 + 2 is 15, some odd ones

\bf \stackrel{\textit{3 times the first}}{3a}~~=~~\stackrel{\textit{26 less than twice the sum of the others}}{2[~(a+2)+(a+4)~]~~~-26}
\\\\\\
3a=2[~2a+6~]-26\implies 3a=4a+12-26\implies 3a=4a-14
\\\\\\
0=a-14\implies 14=a

what are the other two consecutive integers?  well, a + 2 and a + 4.

What is the solution for the =.
liq [111]

Answer:

solution for n is \frac{-13}{4}

Step-by-step explanation:

Given an equation containing one variable n.

The equation is as follows:

\frac{-5}{2} =\frac{3}{4} +n

To solve for n we can subtract 3/4 from both the sides

The result is

\frac{-5}{2} -\frac{3}{4} =n\\Take LCD as 4\\\\frac{-10-3}{4} =n

Verify:

Substitute the answer in the given equation.

\frac{-5}{2} =\frac{3}{4} -(\frac{13}{4} )

Both sides equal thus proving our correctness of answer.

WILL GIVE BRAINLST <br><br> HAVE A GOOD DAY
Sedbober [7]
1st one 17/100 2nd one 0.25


Because 0.17 would be like 17% out of 100% so the fraction simplified is 17/100

2. Since the area of a square is length×length
But according to the question we are asked to find the length and the area is given so we will have to solve this
L×L= area
L^2=0.25
Square root both sides
L=√0.25
L=0.5
Therefore the length of the square is 0.5
