Answer:
<h2>120 cars</h2>
Step-by-step explanation:
This problem is on ratio, and we can use part to the whole to arrive at our answer
given that total vehicles is 210 vehicles
the sum of the ratio of cars to trucks is = 4+3= 7
therefore applying part to the whole formula we have
for cars
4/7=x/210
cross multiply we have
7x= 210*4
x= (210*4)/7
x= 30*4
x= 120
So in all there are 120 cars in the lot

Answer:X = 15.2
Step-by-step explanation:
-4+5x= 72+4= 76
5x= 76
X = 15.2
% times amount of each part = % times amount of mix
x = amount of 10%
100 = amount of 100%
x + 100 = amount of 40% mix
10x + 100(100) = 40(x + 100)
10x + 10,000 = 40x + 4,000
-10x - 4000.....-10x - 4000
------------------------------------- 6000 = 30x
so x = 6000 ÷ 30 = 200 mL
