Answer:
13405
Step-by-step explanation:
because 35 x 383 = 13405 so yes
When the number is directly beside a variable (x), you have to multiply the number and variable
Answer:(11,13)
Step-by-step explanation:
3(11)-2(13)=13= 11+2
If you plug these numbers in, you get the correct answers .
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 17.16 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 17.16 is 100%, so we can write it down as 17.16 = 100%.
4. We know, that x is 62.4% of the output value, so we can write it down as x=62.4%
5. Now we have two simple questions:
1) 17.16 = 100%
2) x=62.4%
Where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
17.16÷x=100%÷62.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 62.4% of 17.16
17.16÷x=100/62.4%
(17.16÷x)×x=(100÷62.4%)×x
17.16=1.60256410256×x
(1.60256410256) to get x
17.16÷1.60256410256=x
10.70784=x
x=10.70784
Now we have:
62.4% of 17.16=10.70784
So 10.70784 is your answer
Hope this helps :)
Answer:
y = 1/9 x z^3
Step-by-step explanation:
y is jointly proportional to x and z^3
y = k * x * z^3 where k is the constant of proportionality
y =12, x = 4 and z =3
12 = k * 4 * 3^3
12 = k * 4 * 27
12 = k * 108
12/108 = k
1/9 = k
y = 1/9 x z^3
