Solve: -3= 12x-5(2x-7)
leonid [27]

Answer:

x = -19

Step-by-step explanation:

-3= 12x-5(2x-7)

Distribute

-3= 12x-10x+35

Combine like terms

-3 = 2x +35

Subtract 35 from each side

-3-35 = 2x+35-35

-38 = 2x

Divide each side by 2

-38/2 = 2x/2

-19 =x

Verda used a sensor to measure the speed of a moving car at different times. At each time, the sensor measured the speed of the
USPshnik [31]

Answer:

Option A

Step-by-step explanation:

If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),

m ∝ k

m = ck

Here, c = Proportionality constant

Therefore, c = \frac{m}{k} should be constant for each value given in the table.

For m = 11 and k = 17.699,

c = \frac{11}{17.699}

c = 0.6215

For m = 26 and k = 41.834,

c = \frac{26}{41.834}

c = 0.6215

For m = 34 and k = 54.706,

c = \frac{34}{54.706}

c = 0.6215

Therefore, c is constant for each value of m and k.

Option A will be the correct option.
