A map has a scaling that 5cm = 2km.

How many kilometers are represented by 2cm?

Answer:

23x-4

Step-by-step explanation:

x+22x-4 ( If a term doesn't have a coefficient, it is considered that the coefficient is 1

1x+22x-4 Collect like terms by adding their coefficients (1+22)x-4

Then, add the numbers.

(1+22)x-4

23x-4

Answer:

Math:The Union of A and B is the set of all those elements which belong either to A or to B or both A and B. use the notation A U B (which is read as 'A union B') to denote the union of set A and set B.

Algebra: n(A U B) = n(A) + n(B) - n(A n B) so 20 = n(A) + 10 - 5 OR n(A) = 15.

Answer:

Step-by-step explanation:

Area = 121 in²

Length = √121 in = 11i in

Answer:

x = 0

Step-by-step explanation:

add 7 to each side to get:

2x² = 0

divide each side by 2 to get:

x² = 0

take square root of each side to get:

x = [tex]\sqrt{0}[/tex]

x = 0

Answer:

x = 0

Step-by-step explanation:

[tex] {2x}^{2} - 7 = - 7[/tex]

[tex] = {2x}^{2} = 0[/tex]

[tex] = {2x}^{2} \div 2 = 0 \div 2[/tex]

[tex] = {x}^{2} = 0 \div 2[/tex]

[tex] = {x}^{2} = 0[/tex]

[tex] = x = 0[/tex]

Answer:

81 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

Area of a rectangle is given by the following equation:

Area = Length × Width

A = L × W

With the above formula, we can obtain the width of the rectangular field as follow:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

A = L × W

7371 = 91 × W

Divide both side by 91

W = 7371 / 91

W = 81 m

Thus, width of the rectangular field is 81 m

Step-by-step explanation:

Answer: equation is

c(x)=(10/3)x

54 mints per box

Step-by-step explanation: ok so 3 mints=10 calories

if you input 3 for number of mints, ou get 10 for caloires

10=k3

divide both sides by 3

10/3=k

therfor

C(x)=(10/3)x

full box =180 caloies

therefor

full=180=(10/3)x

multiplyboth sides by 3/10 to clear fraction (since 10/3 times 3/10=30/30=1)

540/10=x

54=x

Answer:

125 Dollars

Step-by-step explanation:

Total fee = 7000

Amount in hand = 4000

Amount to be saved in 2 years = 7000 - 4000 = 3000

No of months in 2 years = 12 x 2 = 24

Per month saving = 3000 / 24 = 125 $

Answer:

a)  (2 x 1000) + (5 x 100)

b)  5^4 × 2²

c)  ??

Step-by-step explanation:

b) 2500 = 25 x 100

25 = 5 x 5

100 = 25 x 4 = 5 x 5 x 2 x 2

Answer:

8x+6y

Step-by-step explanation:

add the coefficients of like terms with the same variable

Answer:

v=15t/(w+30)

Step-by-step explanation:

multiply by w

wv=15(t-2v)

expand brackets

wv=15t-30v

+30v on both sides

wv+30v=15t

factorize to remove v

v(w+30)=15t

divide by (w+30)

v=15t/(w+30)

After making {v} the subject of the formula, we get -

v = 15t/(w + 2).

An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -

2x + 3y + 5

2z + y

x + 3y

Given is to make {v} the subject of the formula -

w = 15(t - 2v)/v

The given equation is -

w = 15(t - 2v)/v

w = 15t/v - 2v/v

w = 15t/v - 2

w + 2 = 15t/v

v = 15t/(w + 2)

Therefore, after making {v} the subject of the formula, we get -

v = 15t/(w + 2).

Answer: D, 36in.

Step-by-step explanation:

Answer:

$1573.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 31470 × 0.05 × 1 = 1573.5

I = $ 1,573.50

The simple interest accumulated

on a principal of $ 31,470.00
