The ratio of red marbles to green marbles, [tex]r:g=5:7[/tex]

The first sentence about what happens to the bag of marbles;

"When one red marble is removed and one green marble added, the ratio of red to green marbles is now 2:3"

Leads to the fractional equation

[tex]\frac{r-1}{g+1}=\frac{2}{3}[/tex]

After rearranging, we get equation (1) [tex]3r-2g=5[/tex]

The next sentence about what happens to the bag of marbles;

"Subsequently, 6 red marbles and 4 green marbles are added, such that the ratio of red to green marbles is now 3:4"

Leads to the fractional equation

[tex]\frac{r-1+6}{g+1+4}=\frac{3}{4}\implies \frac{r+5}{g+5}=\frac{3}{4}[/tex]

Since the first change to the bag was done without replacement. After rearranging, we get equation (2) [tex]4r-3g=-5[/tex]

So we need to solve the simultaneous equations for [tex]r[/tex] and [tex]g[/tex]

[tex]3r-2g=5\\4r-3g=-5[/tex]

Which gives [tex]r=25[/tex] and [tex]g=35[/tex]

Therefore, the ratio, [tex]r:g=25:35=5:7[/tex]

Answer:

x = 4

Step-by-step explanation:

First we will subtract 7 from 11 to get

-x = 4 - 2x, next we will add 2x to -x to get

x = 4.

(It's just a matter of combining like terms.)

Step-by-step explanation:

Answer:

a. n=6

b. n = 4

c. n =2

d. n = 11 ÷ 5

e. n = 10

f. 20

Step-by-step explanation:

a. 5n = 30

n=30÷5

n=6

b. 3n-1 = 11

3n= 11 + 1

n = 12 ÷3

n=4

c. 4n + 7 = 15

4n = 15 - 7

n = 8 ÷ 4

n = 2

d. 5n = 11

n = 11 ÷ 5

e. 4 + n = 40

n = 40 - 4

n = 10

f. 5 + 15 = 20

10+6 = 16

since 112/16 = 7

add 7*10 white and 7*6 striped

Answer:

Alright, solve 10 + 6 = 16

Place a proportion of 10 / 16 and 6 / 16

Multiply 10 and 112, and 6 and 112, and divide both by 16

This will get you 70 / 42

70 / 42 = 10 / 6

70 * 6 = 420, 42 * 10 = 420

420 = 420

70 white golf balls, and 42 striped.

Answer:

4√2

Step-by-step explanation:

as it is an isosceles 2 sides will have the same side length so 4 and 4, therefore you can use pythagoras theorem to solve for x.

do 4²+4²=32 then square root this √32 which is equal to 4√2

The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

As per the given isosceles triangle.

The angles opposite to equal sides in the isosceles triangle will be the same.

And, The two sides of the isosceles triangle will be the same.

Both perpendicular sides' length = 4

By Pythagoras theorem,

x = √(4² + 4²)

x = √32 = 4√2

Hence "The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2".

Answer:

( AB )² + 12 = 162

Step-by-step explanation:

By Pythagoras theorem,

( AB )² + ( BC )² = ( AC )²

( AB )² + ( 2√3 )² = ( 9√2 )²

( AB )² + 12 = 162

Step-by-step explanation:

it's a right angled triangle so to find the measures of 3rd side we use hypotenuse formula which is,

h² = a² + b²

here in the given figure we have to find base or b²

(AC)² = (CB)² + (AB)²

we know,

AC = 9√2

CB = 2√3

now,

162 = 12 + AB

THEREFORE, OPTION B is correct.
