Let Terry Saved be T dollars .

The Expression will be

[tex]\\ \rm\longmapsto Sala+Terry=\$10.00[/tex]

[tex]\\ \rm\longmapsto D+T=\$10.00[/tex]

Answer:

T = 10 - S

Step-by-step explanation:

The only useful information is that  they saved $10 together. We are just going to add the money Sala and Terry saved to equal 10.

S + T = 10

They want an expression for how much Terry saved so we can solve for T.

T = 10 - S

Best of Luck!

Answer:

e) 14

Step-by-step explanation:

(18-n)/2 = 2

18-n = 4

-n = -14

n = 14

The value of n when n is subtracted from 18 and the difference is divided by n, the result is 2 is 6.

The representation of mathematical statements as solutions to problems is the focus of the branch of mathematics known as algebra. Mathematical operations like addition, subtraction, multiplication, and division are combined with variables like x, y, and z to produce a meaningful mathematical statement.

Given:

When a number n is subtracted from 18

=(18- n)

and, the difference is divided by n

=(18 - n)/n

so, result is 2

(18 - n)/n = 2

18 - n = 2n

3n = 18

n= 18/3

n= 6

Hence, the value of n is 6.

Answer:

9

Step-by-step explanation:

let a = 2

b = 5

2a + b

Substituting the values,

=> 2(2) + 5

=> 4 + 5

=> 9

Let us consider that a = 2 ; b = 5

So, 2a + b

Substitute,

2a + b

→ 2×2 + 5

→ 4 + 5

→ 9

Step-by-step explanation:

x + 30 = 180 - 2x   [vertically opposite angles]

x = 180 - 30 - 2x

x + 2x = 150

3x = 150

x = 150/3

x = 50

Answer:

Rate =interest*100/principal*time

Rate = 7.5%

Step-by-step explanation:

At 7.5 % annual rate of interest did she invest her money.

The percentage usually on an annual basis that is paid by the borrower to the lender for a loan of money is called rate of interest.

Given

Principal P = $10800

Time t = 4 years

I = 3240

Interest = [tex]\frac{P\times r \times t}{100}[/tex]

[tex]3240 = \frac{10800\times r \times 4}{100}[/tex]

[tex]r= \frac{3240\times 100}{10800\times 4}[/tex]

r = 7.5 %

At 7.5 % annual rate of interest did she invest her money.

Answer:

I'm guessing y is numerator and 5 is denominator. so y^2/25

Step-by-step explanation:

so if you have the fraction y/5 and you need to square it or raise to the second power you get (y/5)^2. now using the properties of exponents when you get a fraction and need to raise it to a power you square the denominator and numerator which gets you y^2/25. now let's check if it works we can use 5 for y so (5/5)^2 is equal to 25/25 = 1. or (10/5)^2 which is 2^2 = 4. or 100/25 which is 4. so the equation works for the expression.

Answer:

C. 640π cubic units

The area of a square with sides of length 9 is 81 square units.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

The space enclosed by the boundary of a plane figure is called its area.

The area of a figure is the number of unit squares that cover the surface of a closed figure.

Given that, a square with side length of 9 units, we need to find its area, We know that, the area of a square is given by the square of it side, so Area = side²

Area of the given square = 9²

= 9 x 9

= 81 sq. units

Hence. the area of a square with sides of length 9 is 81 square units.
