3(8x - 5) = -4(7 - 6x)
Distribute 3 and -4 inside their respective parentheses.
24x - 15 = -28 + 24x
Add 28 to both sides.
24x + 13 = 24x
Subtract 24x from both sides.
13 = 0
This is an untrue statement, so that means there are no solutions to this equation.
Your answer is no solution.
A) distribute the 5 to the x and 4 in parenthesis. this gives you (-5 + 5x + 20)
b) combine -5 and 20, the two constants. this gives you (5x + 15)
Answer:
Ratio time to the number of burritos = 4:9
Step-by-step explanation:
Given:
Number of burritos make = 18
Total time taken = 8 min
Find:
Ratio time to the number of burritos
Computation:
Ratio time to the number of burritos = Total time taken / Number of burritos make
Ratio time to the number of burritos = 8 / 18
Ratio time to the number of burritos = 4 / 9
Ratio time to the number of burritos = 4:9
A ratio can be written 3 ways.
1. a to b
2. a:b
3. a
----
b
Now when we are working with ratios we ALWAYS put the numbers the way the question asks.
It says wat is the ratio of cheese pizzas to pepperoni pizzas sold each week, So we need to put the amount of cheese pizzas 1st, then the amount of pepperoni pizzas.
45:20
45 to 20
45
------
20
Now we will SIMPLIFY.
45 ÷ 5 = 9
20 ÷ 5 = 4
So, our new ratio would be C. 9:4.
Hope I helped ya!!
Answer:
The constant of proportionality is 3/2
B is correct.
Step-by-step explanation:
We are given a table of Time (x) and Number of pages (y)
In x minutes printer prints y number of pages.
As we know the it would be direct proportion because if time increase number of printing page increase.
Thus, y=kx
x is time ( independent variable)
y is number of pages (dependent variable)
k is constant of proportionality.
From table we will take the value of x and y and to solve for k
x=2, y=3
3=2k
Hence, The constant of proportionality is 3/2
