Answer: it’s geometry
Step-by-step explanation:
Step-by-step explanation:
x=y+7
3x+2y=6
so wherever you see X you but y+7
3(y+7)+2y=6
3y+21+2y=6
group like terms
3y+2y=6-21
5y=-15
divide by 5
y=-3
to find x sub the y value in the equation
x=y+7
x=-3+7
x=4
2/3 - 3/4
x - 3
x= (2/3 * 3) / (3/4) = 2 * (4/3) = 8/3 = 2 and 2/3 of tablespoon of salt
Answer:
P odd number, then 20) = 1 /14
Step-by-step explanation:
P( odd number) = number of odd numbers/ total
number of odd numbers = 3
total = 7
P( odd number) = 3/7
We keep the tile so that there are only 6 tiles left
P (20) = number of 20/ total
= 1/6
We multiply the probabilities together
P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
Answer:
2.5cm^2
Step-by-step explanation:
so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)
so 1.8/2=0.9
now,
pi*0.9^2
pi*0.81
2.5 cm^2
