Step-by-step explanation:
6b + 7 = 331
6b = 324
b = 54 students in each bus
<h2><u>DISTRIBUTIVE PROPERTY</u></h2>
The distributive property indicates that multiplying a number by the sum of two addends is equal to multiplying each addend individually by the number and then adding the products together.
In general terms:
<h3>m(n + p) = mn + mp</h3>
<u>In this exercise</u>:
Let's apply the distributive property:
<h3><u>Answer</u>: 6w - 10y</h3>
Answer:
5,670
Step-by-step explanation:
how do you solve 135x42? (step by step please)
Answer :
= 135 x 42
= 5,670
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751

Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.
Then the volume of the 1% solution is 100-x milliliters.
Then your "concentration" equation is
%280.01%2A%28100-x%29+%2B+0.05%2Ax%29%2F100 = 0.02,
or, equivalently,
100-x + 5*x = 200,
which implies
4x = 100 ----> x = 100%2Fx = 25.
Answer: 25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.
