Okay so the first one, you compare the fractions

3
12 150

3 * 150 / 12

the second, you add the number of beads, so 20 beads, and put them into a fraction with how many beads the red and green are, so 8+6= 14

the fraction is 14
20

now put it to a bead is picked 60 times.

14
20 60

14 * 60 / 20

<h2>Required Answer :-</h2>

Given system of linear equations are ,

x + y = 2
-3x + y = 2

And we need to find the Solution of the linear equation . So let's Firstly number the equations .

$\large{\red{\frak{ Given}}}\begin{cases} \sf x + y = 2\qquad ..........(i) \\\\\sf -3x + y = 2 \qquad ..........(ii) \\\end{cases}$

→ Multiplying equⁿ (i) by 3 ,

=> 3 ( x + y ) = 2*3

=> 3x + 3y = 6

→ Adding the two equations ,

=> 3x + 3y -3y + y = 6 + 2

=> 4y = 8

=> y = 8/4

=> y = 2

→ Put y = 2 in (i) ,

=> x + y = 2

=> x + 2 = 2

=> x = 2- 2

=> x = 0

<h3>★ Hence the required solution is ( 0 , 2 ) .</h3>

For the function f(x) = -4x - 5, what are the outputs for the inputs -4, 1, 3, and 11?

Anika [276]

We have to find the output values for the given input values of the function given as,

f(x) = -4x - 5

Here, x = Input value of the function

And f(x) = Output values

By substituting the input values of x as,

For x = -4,

f(-4) = -4(-4) - 5

= 16 - 5

= 11

For x = 1,

f(1) = -4(1) - 5

= -4 - 5

= -9

For x = 3,

f(4) = -4(3) - 5

= -17

For x = 11,

f(11) = -4(11) - 5

= -44 - 5

= -49

Therefore, Option (A) will represent the output values for the given input values.

Raina must choose a number between 55 and 101 that is a multiple of 2,3 and 9. Write all the numbers that she could choose. If t

ziro4ka [17]

Answer:

72,90

Step-by-step explanation:

Since 9 is the biggest number so list multiples of 9 between 55- 101 range.

Which are 63, 72, 81, 90, 99. Any number that is a multiple of 9 is a multiple of 3 because 3x 3 = 9. 9 is a multiple of 3.

Any even number is a multiple of 2.

Only 72 and 90 are even numbers.

So 72 and 90 are numbers divisible by 2, 3, 9.

A note with a face value 4300 was discounted at 3%. if discount was 21 dollars. find the length of loan in days

Doss [256]

The annual discount is 3%, therefore the total discount for 1 year would be:

4300 × 3 ÷ 100 = 129$

Now, you can set a proportion:

discount : annual discount = loan days : days in one year
21 : 129 = x : 360

x = 21 × 360 / 129 = 58.6 days

Hence, the loan duration was 60 days.
