Find the value of x and y x+y=4 x-y=2​

Answer:

Step-by-step explanation:

x+y = 6

y = (6-x)

7x +12y = 52

7x+12(6-x) = 52

7x +72 -12x = 52

-5x = -20

x= 4     4 days at $7  = $28

           2 days at $12 = $24

 28+24 = 52

subtract 64 from 20

Step-by-step explanation:

so basically for this on u have to draw this on graph every first number of the coordinate is on x axis e.g . (7,0) 7 is on x axis and 0 is on Y axis. you can use tracing paper for this which will be more helpful as u can trace the shape and move it half way.

As u rotate it around the origin so u just turn it half way. eg I drawn it on the picture.

hope this make sense :)

Answer:

Step-by-step explanation:

70+85+150+x=360 degree(sum of 4 angles is always 360 degree)

305+x=360

x=360-305

x=55 degree

Answer:

85+1 50+70+x=360{ sum of interior angels of of quadrilateral}

305+x=360

x=360-305

x=55degree

Answer:

45°

Step-by-step explanation:

Let :-

We know :-

On adding :-

→ x + 3x = 180°

→ 4x = 180°

→ x = 180°/4

→ x = 45°

Answer:

1.37 x 10^-9 F

Step-by-step explanation:

(8.85 x 10^-12) * (0.155) = 1.37 E -12

1.37 E -12 / 0.00100 = 1.37 x 10^-9

-18x

you first times the numbers, which becomes -18

Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)

Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)

-18x

Answer: Select the first one

Step-by-step explanation:

-6 multiplied 3 is -18

AND they both have power x which means  -6x⁸   multiply 3x ⁻⁷

                                                         =  -18 x⁸ ⁺⁽⁻⁷ ⁾(As the have same variable )

                                                         =  -18 x⁸⁻⁷

                                                           =-18 x

Step-by-step explanation:

Answer: 0.03

Step-by-step explanation:

1 block = 1/20 mile = 0.05 miles

4(0.05) = 0.20

3(0.05) = 0.15

A=l•w=0.20(0.15)=0.03

The area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

20 blocks = 1 mile

1 block = 1/20 miles = 0.05 miles

Length of 3 blocks = 3×0.05 = 0.15 miles

Length of 4 blocks = 4×0.05 = 0.20 miles

Area of the Orchard Hill = 0.15×0.20 = 0.03 square miles

Thus, the area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.

From the equation of a line, y = mx + c where m is the slope.

Answer:

The right solution is "$1,920,000".

Step-by-step explanation:

Given:

Project cost,

= $1200000

Dr. Leonard sells by

= 60%,

The mark up value will be:

= [tex]\frac{1200000\times 60}{100}[/tex]

= [tex]720,000[/tex] ($)

hence,

The selling price he should put with the bank will be:

= [tex]Project \ cost+Mark \ up \ value[/tex]

= [tex]1200000+720000[/tex]
