What's the distributive property when solving the equation 7(x+5)-x=42

1 answer:

7 0

When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:

7(x+5)-x=42

7x+35-x=42 -Using distributive property (Multiplication)

6x=7 -Collecting like terms.

x= 7/6 -The answer.

Therefore x would equate to 7/6.

Solve each equation for d when c = 0 <br> 10c+ 4d = 40

Yanka [14]

Hello!

The answer would be d = 10. Solve it like this. (v v v)

10 * 0 + 4 * d = 40 ---> 0 + 4 * 10 = 40

0 + 40 = 40

40 = 40

Hope this helps! ☺♥

Solve for A, need this done in under a half hour please ;-;

Answer:

x=30, and angle A equals 132°.

Step-by-step explanation:

Since the angles are alternate-interior, both angles A and B equal the same amount. To figure out the value of <em>x</em>, you'd need to set up your equation like this:

5x-18°=3x+42°

You would need to solve for <em>x</em>, which should equal to 30.

Once you get your <em>x</em>, you need to plug it in into the equation of angle A, which is 5x-18°:

5(30)-18°

150-18°

Angle A = 132°.

Suppose a scientist reported the following data regarding the presence bacteria during the first four hours of testing for a new

The recursive geometric sequence that models this situation is:

$f(n) = 0.9f(n-1)$

$f(1) = 90000$

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

It can be represented by a recursive sequence as follows:

$f(n) = qf(n-1)$

With f(1) as the first term.

In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:

$q = \frac{65610}{72900} = \cdots = \frac{81000}{90000} = 0.9$

$f(1) = 90000$

Hence:

$f(n) = 0.9f(n-1)$

$f(1) = 90000$
