Flip the fraction to make the -3 exponet positive then it will be 9x^5/3x^3 which the answer would then be 3x^2
Answer : The weight of cinnamon and sugar need to use is, 20 g and 80 g respectively.
Step-by-step explanation :
Total weight of mixture = 100 g
Let the weight of cinnamon be, x
And, the weight of sugar will be, (100-x)
Cinnamon costs = 9¢/g
Sugar costs = 6.5¢/g
Mixture costs = 7¢/g
Total cost of cinnamon = 9¢/g × (x)g = (9x)¢
Total cost of sugar = 6.5¢/g × (100-x)g = (650-6.5x)¢
Total cost of mixture = 7¢/g × (100)g = (700)¢
According to question,
(9x)¢ + (650-6.5x)¢ = (700)¢
(9x)¢ - (6.5x)¢ = (700)¢ - (650)¢
(2.5x)¢ = 50¢
x = 20
The weight of cinnamon = x = 20 g
The weight of sugar = 100 - x = 100 - 20 = 80 g
Answer:
The big bang is showing that there is tiny atoms. The atoms grouped up with gravity and more and more grouped making a super dense dot. The dot exploded making gases creating stars. The stars were bigger so they got new atoms to join creating planets. One planet named was suitable for life so tiny germs. The rest nobody knows.
Step-by-step explanation:
The slope is 1/3 because in order to get from point (3,1) to (6,2) you need to rise 1 and go over 3
Answer:
1.) k + 516
2.) 2n - 4 = 3
3.) 57 - 2s
4.) 9h = 153
5.) c = 5n
Step-by-step explanation:
All of the problems given require you to set up an expression or equation. Expressions have a variable and a coefficient or a constant. Equations also have a variable, coefficient or constant but also include an equal sign.
1.) last year's miles = k, this year = 516, so total: k + 516
2.) twice the difference of a number and 4 equals 3
twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3
2n - 4 = 3
3.) 57 decreased: 57 -; twice her savings: 2s: 57 - 2s
4.) 153 is: 153 =; the product of height and 9: 9h, so 9h = 153
5.) notebooks 'n', were $5 each: 5n; total cost = c, so 5n = c
