-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735

One way you could solve the system of equations of y is using the process of elimination.

-2(5x+2y=7)
-5(-2x+6y=9)

-10x-4y=-14
10x-30y=-45
-------------------
-34y=-59
------ -----
-34 -34
y=1.735

When rounded is y=1.7

The solution for y is 1.7

Have a blessed day! ;)

7. A clothing salesman wants to earn $6,000 in May. He receives a base salary of $4,000 per month as well as 10%
olya-2409 [2.1K]

Answer:

No of clothes to be sold to gain $6000=20,000

Given:

Base salary = $4000

Rate of Commission = 10%

Amount salesman wants to earn in May = $6000

To find:

How much clothing units needed to be sold in order gain $6000 in may

<u>Step by Step Explanation: </u>

Solution;

According to the formula;

\text { Amount earned through commission }=\text { Total amount earned - Base salary }

=6000 - 4000 = 2000

Also we know,  

\text { Amount earned through commission }=\text { Rate of Commission } \times \text { clothing to be sold }

Let the commission amount be x

10 \% \times x=2000

10 / 100 \times x=2000

0.1 \times x=2000

x=20,000 \div 0.1

x=20,000

Result:

Hence, the clothing to be sold in order to earn $6000 is 20,000 units.

Rufina [12.5K]

Answer: Vertex

Step-by-step explanation:

To solve this exercise you must keep on mind the definitions shown below:

1. By definition, a regular pyramid is a right pyramid whose base is a regular polygon.

2. By definition, a regular polygon is a polygon whose sides have equal lenghts.

3. By definition the apex (which is the vertex at the tip of the pyramid) of a right pyramid lies directly above the center of the base.

Therefore, keeping the above on mind, you can conclude that:

A regular pyramid has a regular polygon base and a Vertex over the center of the base.
