Answer:

x = -12

Step-by-step explanation:

-5x + 12 - 7x = -3(5x + 8)​

-5x + 12 - 7x = -15x - 24

-12x + 12 = -15x - 24

-12x + 15x = -24 - 12

3x = -36

x = -12

On Monday, Mr. Roberts drove 42 miles. On Tuesday, he drove 5 miles more than half the distance he drove on Monday. Which expres
butalik [34]

Answer: Last option

(42÷2) +5

Step-by-step explanation:

We know that Mr. Roberts drove 42 miles on Monday.

On Tuesday Mr. Roberts drove half of what he drove on Monday plus 5 miles.

If we want to know how many miles Mr. Roberts drove on Tuesday then we should divide 42÷2 to find half of 42.

\frac{42}{2} = 21

Then we know that in addition to the 21 miles he drove 5 more miles. Then we add 21 +5 = 26 miles.

So the expression that gives us the number of miles that Mr. Roberts drove on Tuesday is:

(42÷2) +5

Find the value of this fraction 6 x 1/2 + 2/3 + 3/4 ​
kodGreya [7K]

Answer:

\frac{53}{12} or 4 \frac{5}{12}

Step-by-step explanation:

\frac{6}{1}  \times  \frac{1}{2}  = 3

\frac{3}{1}  +  \frac{2}{3}  +  \frac{3}{4}  = ...

Find the common denominator, which is 12

\frac{36}{12}  +  \frac{8}{12}  +  \frac{9}{12}  =

Now add them

\frac{36}{12}   +  \frac{8}{12}  =  \frac{44}{12}  +  \frac{9}{12}  =  \frac{53}{12}

Simplified version is

4 \frac{5}{12}
