4/5x = 2/5
(5/4) 4/5 x = (5/4) 2/5 (multiplying both sides by 5/4 to isolate x)
x = 2/4 (5 in the numerator and 5 in the denominator cancels out)
x = 1/2 <--------- This is the answer.
Hope this helps.

lilavasa [31]

We wil name x to the amount of correctly answered questions. Then, we get:

$(x-12)+x=40$ $2x-12=40$ $2x=40+12$ $2x=52$ $x=\frac{52}{2}$ $x=26$

Ben had 26 correct answers, so he missed 40-26= 14.

Answer:

a=2

b=10.5

c=4

d=17.5

Step-by-step explanation:

so 3.5 miles per hour and the columns are miles and then hours

so an equation can be 3.5 (mi/hr) * t (time) = distance

so for a): 3.5*t=7

t=2

b) 3.5*3=distance

distance is 10.5

c) 3.5*t=14

t=4

d) 3.5*5=d

d= 17.5
