Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner that costs $59?

Answer: (8,8)

Step-by-step explanation:

First you need to get a x or y by itself.

I choosed to get y by itself since it would be faster.

-2x + y = -8  (first get -2x to the other side so add 2x)

y = -8 + 2x (then you want to insert that to the other equation)

-x + 4( -8 +2x) = 24      ->    -x -32 + 8x = 24   ->   7x -32 = 24

(add 32 to the other side)

7x = 56 (divide 7 to 56 to get x) x = 8

now insert into the other equation

-2( 8 ) + y = -8     ->     -16 + y = -8 ( move -16 to the other side, so add 16)

then you get your answer, y= 8

Answer:

3 727/1000

Step-by-step explanation:

First, the ones place is 3, so we already know that

Also, there is a 0.727.

There are 3 decimal spaces, so that means thousandths

So, its 3 727/1000

Answer:3 727/1000

Step-by-step explanation: If you convert 3.727 (a decimal) you would get    3 727/1000 (a fraction) So the fourth one in the picture u sent :)

Answer:

8/25

Step-by-step explanation:

The total amount of tickets is 25 so divide 10 from 25 to figure out what you multiply by to get 25

--> 25/10 = 2.5

now multiply 2.5 x 3 to have a numerator which would be your probability of winners out of 25 tickets

--> 2.5 x 3 = 7.5 (round to the nearest whole number)

7.5 rounded to the nearest whole number --> 8

so you get 8 out of 25 = 8/25

Answer:

300 [tex]in^{2}[/tex]

Step-by-step explanation:

First, calculate the area of the rectangle. The height and width are 10 and 20, so the area is 200 [tex]in^{2}[/tex].

For the triangle, we know the base length is 10 inches. But for the height, you add the 10 inches that happens to be part of the rectangle and another 10 inches, which is shown to the left of the top of the triangle, making the height 20 inches. Following the formula for the area of a triangle, [tex]\frac{bh}{2}[/tex], you would get 100 [tex]in^{2}[/tex].

To get the total area of the whole figure, add 200 and 100, which will give you 300 [tex]in^{2}[/tex]

Answer:

marque sans cervelle

Step-by-step explanation:

Answer:

0.47 cm, 0.3 cm, 0.11 cm, or 0.55 cm

Step-by-step explanation:

Well, the question doesn't have a mathematical sign, like addition or subtraction, so I did all of the possible signs.

Addition: 2.5 + 2.2= 4.7 mm; converted to cm= 0.47 centimeters

Subtraction: 2.5-2.2= 3 mm; converted to cm= 0.3 centimeters

Division: 2.5/2.2= 1.1 mm; converted to cm= 0.11 centimeters

Multiplication: 2.5 * 2.2= 5.5 mm; converted to cm= 0.55 centimeters

Or, is the question asking to only convert 2.5 mm and 2.2 mm to centimeters?

In that case, the answers are 2.5mm= 0.25 centimeters; 2.2 mm= 0.22 centimeters.

Answer:

7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.

Answer:

1.

7x+11y-(5x+6y)

7x+11y-5x-6y

2x+5y

2.

13x+12y-(6x+2y)

13x+12y-6x-2y

7x+10y

3.

Answer:

1. 40

2. 1.5

Step-by-step explanation:

You'll have to divide 240 by 6 to see how many miles she went per hour so she went 40 miles per hour so in 6 hours they went 240 miles total. answer is 40 miles per hour

You divide 12 ÷ 6 which is 2 so that's how much the starting price is so 1.5 × 2 is 3 answer is $1.5

I tried! Hope this helped! :)
