Let gift box be x and the Christmas tree be y.

<u>Then:</u>

The equation formed by plugging x in place of gift box and christmas tree will be:

(1) 2x + y + 3 = 16

➛ 2x + y = 13

(2) 3x + y + 1 = 14

➛ 3x + y = 13

Subtracting (2) from (1), And we get:

➛ 3x + y - 2x - y = 0

➛ x = 0

Then, y = 13

<u>We </u><u>need </u><u>to </u><u>find:</u>

• yx + x

= 13 × 0 + 0

= 0

<u>Hence</u><u>:</u><u>-</u>

The cost of all the items will be 0. Congrats for Christmas Bingo!!!

quadrilateral A'B'C'D' is the image of quadrilateral ABCD after being translated 6 units up and 7 units left. Quadrilateral A pr

Firlakuza [10]

Answer:

$B(x,y) = (-10,-1)$

Step-by-step explanation:

Given

$B' = (-3,5)$

Required

Determine B

When a point is translated up, the result is:

$y'->y + h$

Where h is the unit translated

y' is the new point and y is the previous;

So, we have

$5 = y + 6$

$y = 5 - 6$

$y = -1$

When a point is translated left, the result is:

$x'->x + h$

Where h is the unit translated

x' is the new point and x is the previous;

So, we have

$-3 = x + 7$

$x = -3 - 7$

$x = -10$

Hence, the coordinates of B is

$B(x,y) = (-10,-1)$

When rounded to the nearest 100 I am the smallest whole number that becomes 5,000 what number am I

Ray Of Light [21]

<h2>Answer:</h2><h2>The number is 4950</h2>

Step-by-step explanation:

Let the number to be identified be represented as x

Given, when rounded to the nearest 100 I am the smallest whole number that becomes 5,000

Therefore, the number is above 4000 and it is a whole number.

When rounded to the nearest 100, I am the smallest whole number that becomes 5,000

The smallest whole number must be 4950 when ronded to 100,it becomes 5000.

The number is 4950

Please help, if you get it right i'll mark you brainliest!!!!!

Digiron [165]

Answer:

Step-by-step explanation:

Back

Area = L * W

L = 20

W = 8

Area = 20 * 8

Area = 160

2 Triangles

Area = 1/2 one smaller leg*other smaller leg

one smaller leg = 8

The other one = 15

Area = 1/2 8 * 15 = 60

But there are 2 of them 2 * 60 = 120

Base

L = 20

W = 15

Area = L * W

Area = 20*15 = 300

Front (slanted) Face

L = 20

W = 17

Area = L * W

Area = 20*17 <u> 340</u>

Total 920

Evaluate the expression when g=3 and h= 17 <br> h−5g

Aleks04 [339]

2.
EXPLANATION:
If g= 3 we can replace g with 3.

Now we have h-5 x 3

and if h= 17, we can replace h with 17.

Now we have 17 - 5 x 3.

because of pemdas, multiplication is first

5 x 3 is 15,

17 - 15 is 2.
