Answer:
Store a is 25 cents per ounce, while store b is 33 cents. Therefore store A is a better price per ounce. For eight dollars you can get 32 ounces of granola.
Step-by-step explanation:
<span>A mathematical sentence that contains one or more variables is sometimes called an open sentence.</span>
X represents the number that would be added to the silver cars.
x/40= 4
X=40x4
x=160
Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
3 sides of square is 3*12=36 cm
perimeter for the full circle is 2 * pi * radius
which is =2 * 22/7 * 12 =75.43 cm
so 360° =75.43 cm
for 150° = 75.43/360 *150 =31.43
all together =36 +31.43 =67.43 cm
