-2x-5y=3 3x-8=-6 solve by substition

Answers

Maybe use photo math i guess

Answer:

x = 2/3

y = -13/15

Step-by-step explanation:

3x – 8 = -6

+8 +8

[addition property of equality]

3x = 2

÷3 ÷3

[division property of equality]

x = 2/3 → -2x – 5y = 3

[substitution property]

-2(2/3) – 5y = 3

[distributive property]

-4/3 – 5y = 3

[Create the proportional equivalent of each term so that all terms share the same denominator]

-4/3 – 15y/3 = 9/3

[multiplication property of equality]

3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )

[distributive property]

-4 – 15y = 9

+4 +4

[addition property of equality]

-15y = 13

÷-15 ÷-15

[division property of equality]

y = -13/15

You have $4000 to enclose a rectangular piece of property with a fence. The fence costs $11 per foot. A scale drawing of the property has a length of 9 inches and a width of 7 inches. The scale is 1 in. : 12 ft. How much will it cost to enclose the property with the fence? Do you have enough money?

Answers

The scale perimeter would be 32 inches, so the actual perimeter 32x12=384 ft. Since each foot costs $11, the total cost would be 11x384= $4224, which is over your budget so you do not have enough money to build the fence.

You won’t have enough money

Here is a diagram that represents (3.1) ⋅ (1.4).
What is the area of rectangle A?
What is the area of rectangle B?
What is the area of the outer rectangle which measures 3.1 units by 1.4 units?

Answers

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

area =lxb

=3.1units x 1.4units

=4.34units

Answer:

1) 3.1 2) 1.24 C) 4.34

Step-by-step explanation:

Area = l(w)

Area of rectangle A:

3.1 * 1 = 3.1

Area of rectangle B:

0.4 * 3.1 = 1.24

Both rectangles put together:

First, let's add 1 to 0.4... 1.4

1.4 * 3.1 = 4.34

Answers

Answer:

528 dollars

Step-by-step explanation:

The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:

First we got 20% off so I did 100 - 20 and got 80%

1: 80% * 600 = 80/100 * 600 = 480

Then we get an increase of 10% so I multiplied 110% with 480 which was our new price

2. 110/100 * 480 = 11 * 48(simplifying)

= 528

528: - 20 % then add 10 %
