Answer:

Step-by-step explanation:

Let Bart's cards = t

Let Tom's cards = b

Adding up Bart's and Tom's cards will add up to 163 like this

b + t = 163

Also Bart has 11 more than Tom

b = t + 11

Plug in the new b

t + 11 + t = 163

2t + 11 = 163

Subtract 11 from both sides

2t + 11 = 163

- 11 - 11

2t = 152

Divide both sides by the coefficient, 2, to isolate the variable, t.

2t/2 = 152/2

t = 76

Answer:

Step-by-step explanation:

If Bart has 11 more than Tom, you can't have a. If the addition is 163, then you can add 76 and 87. Bart has 87 and Tom has 76.

The 6th term of the geometric sequence is of -4096.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

For this problem, we have that:

The first term is $a_1 = 4$ .

$a_n = -4a_{n - 1}$ , hence the common ratio is q = -4.

Thus the 6th term of the sequence is found as follows:

$a_6 = a_1q^5 = 4(-4)^5 = -4096$

Please answer this question

makvit [3.9K]

Step-by-step explanation:

Using the properties of logarithms, the left side of the equation becomes

$\log{3x^3} - \log{x^2} = \log{3x}$

while the right hand side becomes

$\log{27} - \log{x} = \log{\frac{27}{x}}$

so we end up with

$3x^2 =27 \Rightarrow x = 3$

Answer:

2.5•2 = 5

Step-by-step explanation:

The resulting two-dimensional cross-section is the area of a square.

Area of a square is equal to:

$A=bh$

Having

$b = 2.5\ in\\h = 2\ in$

substitute

$A=2.5*2=5\ in^{2}$

Mildred bought 2-cent stamps, 4-cent stamps, and 5-cent stamps for $4.35. The number of 2-cent stamps exceeded the number of 5 c

vfiekz [6]

5 cent = 0.05x

2 cent = 0.02(x+50)

4 cent = 0.04(2x-10)

0.05x + 0.02(x+50) + 0.04(2x-10)

0.05x + 0.02x +1 + 0.08x -0.4 = 4.35

0.15x +0.6 = 4.35

0.15x = 3.75

X = 3.75 / 0.15 = 25

25 5 cent stamps ( 25*0.05 = 1.25)

25+50 = 75 2 cent stamps ( 75*0.02 = 1.50)

2*25 =50-10 = 40 4 cent stamps ( 40*0.04 =1.60)

1.25 + 1.50 +1.60 = 4.35

5 cent = 25

2 cent = 75

4 cent = 40
