A simple problem! To find what two numbers create a given number, subtract a number (or add a number). The number you get minus the number you added/subtracted will be equal to the target number. For example:

42000-1=41999
So that would mean 41999-(-1)=42000
You could also do:
42000+1=42001
Then that would mean 42001-1=42000. Hope this helps!

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One a

Minchanka [31]

Answer:

II. One and only one solution

Step-by-step explanation:

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.

Let assume the equation is given as;

x + 3y = 11 .... 1

x - y = -1 ....2

Using elimination method

Subtract equation 1 from 2

(x-x) + 3y-y = 11-(-1)

0+2y = 11+1

2y = 12

y = 12/2

y = 6

Substitute y = 6 into equation 2:

x-y = -1

x - 6 = -1

x = -1 + 6

x = 5

Hence the solution (x, y) is (5, 6)

Hence we can say the equation has One and only one solution since we have just a value for x and y

Prove that the value of the expression: 731^2−631^2 is divisible by 100

Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

10x = "10 times a number"

+84 = "increased by eighty four"

=194 = "equals 194"

10x+84=194

Subtract 84

10x = 110

Divide by 10

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?

KengaRu [80]

Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = $\frac{2}{9}x$

Number of girls = $\frac{2}{9}x +95$

Number of boys + Number of girls = total members

$\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9$

x = 171

Number of boys = $\frac{2}{9}*171$ = 2 * 19 = 38

Number of girls = 38 + 95 = 133
