X=3 because you have to isolate the variable by dividing each side by factors that don’t contain the variable .
Answer:
80
4
Step-by-step explanation:
You are correct in placing 80 in the box in the table. If you examine the table and the pattern, you'll see that as the number of marbles increases by 10, the weight of the bags increases by 40.
We can determine the rule by dividing 40 by 10: 40 ÷ 10 = 4.
So, the rule is actually to divide the weight of the bag by 4 to find the number of marbles.
Note that this is likely because each marble is 4 grams.
Answer:
B
Step-by-step explanation:
sine = opposite/hypotenuse
sin45 = x/4
sin45/1 = x/4
cross multiply
1 × x = 4 × sin45
x = 4sin45
x = 2.828427125
x = 2 × square root of 2 = 2.828427125
Kg means kilo grams. kilo means 1000 so 1 kilogram is 1000 grams so
7085grams
conversion from grams to kilograms=kg/1000g
so 7085g times kg/1000g=7085/1000 kg=7.085 kg
or if you want kg and g then find out how many times 1000 will go into 7085
it goes in 7 times so 7 kg
then there are 85 grams left over so
7kg and 85g
N = the number
1/2n = n - 8....multiply by common denominator of 2 to get rid of fraction
n = 2n - 16
n - 2n = -16
-n = -16
n = 16 <==
