Answer:

x= -3

Step-by-step explanation:

−2(8x−1)=5(1−3x)

Step 1: Simplify both sides of the equation.

−2(8x−1)=5(1−3x)

(−2)(8x)+(−2)(−1)=(5)(1)+(5)(−3x)(Distribute)

−16x+2=5+−15x

−16x+2=−15x+5

Step 2: Add 15x to both sides.

−16x+2+15x=−15x+5+15x

−x+2=5

Step 3: Subtract 2 from both sides.

−x+2−2=5−2

−x=3

Step 4: Divide both sides by -1.

−x

−1

=

3

−1

x=−3

t = -1400

\boxed{\text{EXPLANATION :}}

Multiply the numbers.

4  ·  2 - 1 · \frac{t}{5} = 288

8 - 1 · \frac{t}{5} = 288

Combine multiplied terms into a single fraction.

8 - 1 · \frac{t}{5} = 288

8 + \frac{-t}{5} = 288

Subtract  8  from both sides of the equation.

8 + \frac{-t}{5}  = 288

\frac{-t}{5}  = 280

Multiply all terms by the same value to eliminate fraction denominators.

\frac{-t}{5}  = 2 8 0

5 · \frac{-t}{5} = 5 ·  280

Cancel multiplied terms that are in the denominator.

5   ·  \frac{-t}{5} = 5 ·  280

-t = 5 · 280

Multiply the numbers.

-t = 5 · 280

- t = 1400.

Divide both sides of the equation by the same term.

- t = 1400

\frac{-t}{-1} =\frac{1400}{-1}

Simplify.

t = - 1400

Solution.

- 1400.

Martin's running ability is measured by this proportion:
jek_recluse [69]

Answer:

A = 13 B =0 = 1/2   This way x in a graph can be his start running ability (time) each A value applied will divide by 1/2 to make 6.5 and when x = 21 then y can be 7 with the AB equation above as 13 x 1/2 = 6.5. add multiple 0 doesn't occur because we start with x value 21 to show the starting value. Alternately x= 137 and y = 0. Then the graph can go up or down when his running value changes as a negative decrease 137 - b = -? and a positive increase will show increase 137+b = +?.
