Step-by-step explanation:

800 + 500 + 1000 + 100 + 100 =total amount of houses sold

= 2500 houses

Houses sold in Stamford + houses sold in Morristown = 800+500

= 1300

1300/2500 = 13/25 = 52/100

therefore the percentage is 52%

Solve the equation-8+6m= 1/2(4m+16) for m

Lena [83]

Answer:

m = 4

Step-by-step explanation:

Given

- 8 + 6m = $\frac{1}{2}$ (4m + 16) ← distribute parenthesis

- 8 + 6m = 2m + 8 ( subtract 2m from both sides )

- 8 + 4m = 8 ( add 8 to both sides )

4m = 16 ( divide both sides by 4 )

m = 4

A flat rectangular piece of aluminum has a perimeter of 70 inches. The length is 11 inches longer than the width. Find the width

rodikova [14]

perimeter = 2L +2w

L = w+11

70 = 2(w+11) +2w

70 = 2w+22+2w

70= 4w + 22

48 = 4w

w=48/4 = 12

width = 12

length = 12+11 = 23

2x12 = 24

2x23 = 46

46+24 = 40

length = 23 inches, width = 12 inches

two families are saving up for a summer trip the smith family originaly has 1000 dollars and will save 50 dollars every week the

SCORPION-xisa [38]

1000 + 50x = 500 + 75x

First move 500 by subtracting it from 1000.
500 + 50x = 75x

Now subtract 50x from 75x.
500 = 25x

Then divide 500 by 25.
20 = x

They would've saved the same amount($2,000) on the 20th week.

What’s the answer to the top question and steps how to solve?

Leviafan [203]

Answer:

-3.69

Step-by-step explanation:

Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

$Ln(a^b)=bLn(a)$

Now lets work out this problem:

$16^{2x+3}=13^{x-1}\\Ln(16^{2x+3})=Ln(13^{x-1})\\(2x+3)Ln(16)=(x-1)Ln(13)$

Using calculator, we take the values of Ln 16 and Ln 13 as:

Ln 16 = 2.7726

Ln 13 = 2.5649

Now, we can solve for x:

$(2x+3)Ln(16)=(x-1)Ln(13)\\(2x+3)2.7726=(x-1)2.5649\\5.5452x+8.3178=2.5649x-2.5649\\2.9803x=-10.8827\\x=-3.69$

x is -3.69 (rounded to 2 decimal places)
