Mathematics
1 answer:
inna [77]2 years ago
7 0

Answer:

x=9

Step-by-step explanation:

Since y=18

The new equation is 2x+3*6=36

Moving some terms, it stays like the following:

2x=36-18

solving for x, give us that x=9

Express the terms of the following geometric sequence recursively.
BabaBlast [244]

Answer:

The most correct option for the recursive expression of the geometric sequence is;

4. t₁ = 7 and tₙ = 2·tₙ₋₁, for n > 2

Step-by-step explanation:

The general form for the nth term of a geometric sequence, aₙ is given as follows;

aₙ = a₁·r⁽ⁿ⁻¹⁾

Where;

a₁ = The first term

r = The common ratio

n = The number of terms

The given geometric sequence is 7, 14, 28, 56, 112

The common ratio, r = 14/7 = 25/14 = 56/58 = 112/56 = 2

r = 2

Let, 't₁', represent the first term of the geometric sequence

Therefore, the nth term of the geometric sequence is presented as follows;

tₙ = t₁·r⁽ⁿ⁻¹⁾ = t₁·2⁽ⁿ⁻¹⁾

tₙ =  t₁·2⁽ⁿ⁻¹⁾ = 2·t₁2⁽ⁿ⁻²⁾ = 2·tₙ₋₁

∴ tₙ = 2·tₙ₋₁, for n ≥ 2

Therefore, we have;

t₁ = 7 and tₙ = 2·tₙ₋₁, for n ≥ 2.

Please brake down why !
lana66690 [7]

Answer:

D

Step-by-step explanation:

using the rule of radicals

• \sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

simplifying \sqrt{32}

\sqrt{32} = \sqrt{16(2)} = \sqrt{16} × \sqrt{2} = 4\sqrt{2}

\sqrt{32} + 5\sqrt{2}

= 4\sqrt{2} + 5\sqrt{2} = 9\sqrt{2} → D

Find the value of X<br><br> A.66<br><br> B.58<br><br> C.32<br><br> D.68
Alina [70]

1) Δ ABC

m∠B + m∠C + m∠BAC = 180⁰

2) m∠DAB + m∠BAC = 180⁰ because m∠DAB and m∠BAC are supplementary angles.

3) m∠B + m∠C + m∠BAC = m∠DAB + m∠BAC

m∠B + m∠C = m∠DAB

32⁰ + x = 98⁰

x=98 - 32 = 66 ⁰

Answer: A. 66⁰.

Whates 2 divided by 3 z= -6
GalinKa [24]

z = 20/3 = 6.667

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2/3-(z-6)=0

Step by step solution :

Step 1 :

2

Simplify —

3

Equation at the end of step 1 :

2

— - (z - 6) = 0

3

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

z - 6 (z - 6) • 3

z - 6 = ————— = ———————————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2 - ((z-6) • 3) 20 - 3z

——————————————— = ———————

3 3

Equation at the end of step 2 :

20 - 3z

——————— = 0

3

Step 3 :

When a fraction equals zero :

3.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

20-3z

————— • 3 = 0 • 3

3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

20-3z = 0

Determine if $3 for 6 bagels is equivalent to $9 for 24 bagels
Leokris [45]

It isn't because since 9 is the product of 3×3, you multiply the 6 by 3 as well, which makes 18.
