Answer:

12 cards

Step-by-step explanation:

there are three 1/3 in a whole piece of paper. if we have 4 sheets and can make 3 cards out of 1 sheet, multiply 3 by 4 and get 12.

Please look at the worksheet below.  Hope it helps!

Step-by-step explanation:

First, find 12 percent of 1,150,

12 percent of 1,150 = 138.

Now, add 1,150 + 138,

1,150 + 138 = 1,288

Answer:

The triangle is an isosceles triangle

Answer:

it's answer is 33°

Step-by-step explanation:

116° + 31° + m<1 = 180° [being sum of angles of triangle ]

147° + m< 1 = 180°

m<1 = 180° - 147°

m<1 = 33°

Step-by-step explanation:

4x + 2y = 10 --------(1)

2x + 3y = 33 -----------(2)

Multiply 2 with eq. (1) and 4 with eq. (2)

8x + 4y = 20 ____________(3)

8x + 12y = 132 ______(4)

Subtracting (3) from (4),

8x + 4y = 20

- 8x -12y = -132

----------------------

0 -8y = -112

y = 112/8

y = 4 is the answer.

Putting the vakue of y in eq. (2),

2x + 12 = 33

2x = 33-12

2x = 21

x = 21/2 is the answer.

b) 6×3+4

Step-by-step explanation:

Answer:

(x + 8) / 6

Step-by-step explanation:

The sum of x and 8, meaning x + 8 is being divided by six, so we group x + 8 in parentheses, and divide by 6 to get the answer

Answer:

6710.46x

Step-by-step explanation:

The solution is : the value of x is x = 9.75.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:

Step 1: You must divide the numerator of the fraction by the denominator of the fraction.

Step 2: Now you must add the quotient obtained to the Whole number part.

So, you get:

3 + 1/4

=3 + 0.25

= 3.25

Then, the scale image that maps "Figure a" onto "Figure b" is:

1: 3.25

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .

Therefore, you get that the result is:

x = 3 * 3.25

or, x = 9.75

Hence, The solution is : the value of x is x = 9.75.

Answer:

$372.01

Step-by-step explanation:

50% of $236.87 is half of it, which means the console is being sold for $118.44 because:

235.87/2 = 118.435

Round this to the nearest cent:

$118.44

If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:

490.45 - 118.44 = 372.01

You will have $372.01 left.

If anything just divide or multiply 80 1/2 by any number and it will give you something equivilent

Step-by-step explanation:

2√20 is the equivalent expression of the value  [tex]80^\frac{1}{2}[/tex].

A number system is defined as a system of writing to express numbers.

The given expression is [tex]80^\frac{1}{2}[/tex]

We have to find the equivalent expression of  [tex]80^\frac{1}{2}[/tex]

[tex]80^\frac{1}{2}[/tex] can be written in radical form which is √80

80 can be written as 4 times of 20

√4×20

The square root of 4 is 2

So 2√20

Hence, 2√20 is the equivalent expression of the value  [tex]80^\frac{1}{2}[/tex].
