Answer:

15t+9 ft

Step-by-step explanation:

Given data

Width=  6t-1.5 ft

Length= 1.5t+6 ft

Required

The perimeter

The expression for perimeter is

P= 2L+2W

P= 2(1.5t+6)+ 2(6t-1.5)

open bracket

P= 3t+12+ 12t-3

collect like terms

P= 3t+12t+12-3

P= 15t+9 ft

Hence the perimeter is  15t+9 ft

Step-by-step explanation: You can use an online calculater to answer this problem. Other than that, you can use the process of long multiplication to get this answer.

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:

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]

Step-by-step explanation:

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

Answer:

Step-by-step explanation:

x²y = k, where k is a real constant.

When x = 3.5, y = 8.

=> (3.5)²(8) = k, k = 98.

When y = 8/9,

we have x²(8/9) = (98).

=> x² = 110.25

=> x = 10.5 or x = -10.5.

Since we want the negative value,

the answer is x = -10.5.

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:

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.
