Answer:

It is distributive porperty because

7x8 + 7x5

Step-by-step explanation:

you distribute 7 to 8 and 5.

Ex 7x8 + 7x5

The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

You’d use ur outside number (7) and place that in the first part of both your brackets. Then add your 5 to one bracket and you 8 to the other and boom

A car salesperson sells a used car for $ and earns % of the sale price as commission. How many dollars does the salesperson ea

Arisa [49]

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.

A line contains the points (-1, 6), (6, k) and (20, 3). What is the value of k?

AURORKA [14]

Consider, pls, this option:
1. if a required line has a form y=ax+b, then points A(-1;6); B(6;k) and C(20;3) belong to it.
2. According to the item 1 it is possible to make up the system of equations for A and C:
$\left \{ {{-a+b=6} \atop {20a+b=3}} \right \ \left \{ {{a=- \frac{1}{7} } \atop {b= \frac{41}{7} }} \right.$
Knowing, that a=-1/7 and b=41/7, it is possible to write the equation of required line:
$y=- \frac{1}{7}x+ \frac{41}{7}$
3. Using coordinates of point B:
$k=- \frac{6}{7}+ \frac{41}{7} =5 \ where \ k=y$

Evaluate the following expressions. Let a = 5, b = -4, and c = 10.

frozen [14]

Answer: -20, 6, 2, 5

Step-by-step explanation:

a = 5, b = -4, c = 10

12. ab = 5(-4) = -20

13. b + c = -4 + 10 = 6

14. c/5 = 10/5 = 2

15. c - 5 = 10 - 5 = 5

Find approximate radius of a circle that has an area of 60 square centimeters

elena-14-01-66 [18.8K]

Area of circle = πr^2
60=πr^2

we need to find radius (r)
so we solve for r
r^2=60/π
r=√(60/π)
r= 4.37
