Answer:
x=[tex]1.22930[/tex]
Step-by-step explanation:
47(218 x+12 ) =−2(17 −528 x)
Simplify 47(218 x+12 ) : 327(21x+4) 327(21x+4) =−2(17 −528 x)
Multiply both sides by 7(21x+4)
327(21x+4) · 7(21x+4)=−2(17 −528 x)· 7(21x+4)
Simplify, 32=−14(17 −528 x)(21x+4)
Solve 32=−14(17 −528 x)(21x+4): x=32+4√589105 , x=32−4√589105 x=32+4√589105 , x=32−4√589105
Answer:
x = 0.5
Step-by-step explanation:
[tex]\frac{4}{7}(\frac{21}{8}x + \frac{1}{2}) = -2(\frac{1}{7} - \frac{5}{28}x)[/tex]
[tex]1\frac{1}{2}x + \frac{2}{7} = - \frac{2}{7} + \frac{5}{14}x[/tex]
[tex]1\frac{1}{2}x - \frac{5}{14}x + \frac{2}{7} = - \frac{2}{7} + \frac{5}{14}x - \frac{5}{14}x[/tex]
[tex]1\frac{1}{7}x + \frac{2}{7} = - \frac{2}{7}[/tex]
[tex]1\frac{1}{7}x + \frac{2}{7} - \frac{2}{7} = - \frac{2}{7} - \frac{2}{7}[/tex]
[tex]1\frac{1}{7}x = - \frac{4}{7}[/tex]
[tex]\frac{1\frac{1}{7}x}{1\frac{1}{7} } = \frac{- \frac{4}{7}}{1\frac{1}{7} }[/tex]

A cable TV/Internet/phone provider charges new customers $90 for all three services, per month, for the first year
under their 90 NOW promotion. Alice normally pays $59 for her monthly home phone service, $49 for Internet
service, and $69 for cable television
1. What are her percent savings if she switches to the 90 NOW plan? Round to the nearest percent.
Answer:
49%
Step-by-step explanation:
First find how much Alice is paying for the all three service currently.
Amount paid by Alice at present= 59 + 49 + 69 = $ 177
If she switches to 90 NOW plan, then the amount saved = 177 - 90 = $ 87
Percentage of savings = (saved amount ÷ total amount she was paying at present) * 100
[tex]= \frac{87}{177}* 100\\\\= 49.15[/tex]
= 49 %

Explain how you can write a fraction equivalent to 1/4
Answer: 2/8
Step-by-step explanation: becau
Here, we have to write a fraction equivalent to [tex]\sf{ \dfrac{1}{4}} [/tex].
To find a fraction equivalent to the given fraction, we multiply a same number with the denominator and the numerator of the given fraction.Multiply 2 with the numerator and the denominator of the fraction.
→ [tex]\sf{ \dfrac{1}{4} = \dfrac { 1 \times 2}{ 4 \times 2} } [/tex]
→ [tex]\sf{ \dfrac{1}{4} = \dfrac { 2}{ 8} } [/tex]
So, a fraction equivalent to [tex]\sf{ \dfrac{1}{4}} [/tex] is [tex]\sf \red{ \dfrac{2}{8}} [/tex].
Similarly, we can multiply with another numbers (ex : 3,4,5,6) with numerator and the denominator of the given fraction to find the fractions equivalent to the given fraction.
Jim bought some nice running shoes for $216. The sales
tax is 6.5% and he is paying cash with bills only because
he doesn't have any change. What is the least amount
he should give the cashier?
Answer:
I believe the answer is $ 231.00.
Step-by-step explanation:
I might be wrong, but please don't hate me if I am!!
First I found the sales tax of the nice running shoes by multiplying the price of the shoes by the sales tax:
216 * 6.5% = 14.04
Then I added the sales tax to the price of the nice running shoes:
$ 216 + $ 14.04 = $ 230.04
Since Jim doesn't have any change and can only pay in cash, you would round $ 230.04 to the nearest dollar:
$ 230.04 is rounded to $ 231.00 :D

Solve the following triangle using either the law of sines or the law of cosines b=6 , c=12, A=48°
9514 1404 393
Answer:
(a, B, C) ≈ (9.15, 29.2°, 102.8°)
Step-by-step explanation:
The given angle lies between the given sides, so the law of sines cannot be used. The third side is ...
a² = b² +c² -2bc·cos(A) ≈ 83.6452
a ≈ √83.6452 ≈ 9.146
__
Then angle B is found from the law of sines. We want to find the smaller angle, so we can tell if the triangle is acute or obtuse.
sin(B)/b = sin(A)/a
B = arcsin(b/a·sin(A)) ≈ arcsin(0.48753)
B ≈ 29.2°
C = 180° -48° -29.2° = 102.8°
The solution to the triangle is (a, B, C) = (9.1, 29.2°, 102.8°).

The equation 4(x − 2)=100 is a true equation for a particular value of x. Explain why 2(x − 2)=50 is also true for the same value of x.
Please type the answer not a link
Answer:
See below.
Step-by-step explanation:
4(x − 2)=100
Divide both sides by 2.
4/2 (x - 2) = 100/2
2(x - 2) = 50
Since the equation 2(x - 2) = 50 is obtained by dividing the both sides of the first equation by 2, and that is a legal operation because of the division property of equality, then the second equation is equivalent to the first equation and has the same solution.
Estimate 58.311+49.35 by first rounding each number to the nearest whole number.
Answer:
≈107
Step-by-step explanation:
58.311 will round down since 0.311 is less than half or 0.5. It will become 58. 49.35 will also round down since 0.35 is less than 0.5. This will be 49. 58+49=107. Since 107 is not the exact answer, you will use the approximately sign, or ≈.

Part 2B
Answer:
Step-by-step explanation:
I can't read the diagram well enough to tell you how exactly this should be done and I've been reprimanded a couple of times for using comments to solve problems, but this much I can tell you.
You need 2 angles
One comes from vertical angles being equal.
the other comes from the other end of the line that is bisected. Be careful to chose this angel. The two angles are equal because the lines are parallel.
Now what you have is ASA which always proves congruency. AAS should never be used if you can avoid it. If you search out AAS on the internet you will find long discussions on why AAS should never be used.
In this case it will work but even if it does, it should be avoided because you may run into questions where there are conditions that make AAS incorrect. Even if you are told it is OK in your lessons, you should not do it.

$600 invested at 5% compounded daily after a period of 3 years.
Answer:
$697.09
Step-by-step explanation:
The computation of the investment after 3 years is shown below:
As we know that
Amount = Present value × (1 + rate)^number of years
= $600 × (1 + 0.05 ÷ 365)^365× 3
= $697.09
Hence, the investment after 3 years is $697.09
We simply used the above formula to determine the investment

Answer:
Triangle 2: 7, 24 and 25.
Step-by-step explanation:
To find the triangle with its dimensions being that of a right angle triangle;
We would have to apply Pythagorean' theorem.
Let the length of sides of the triangle be;
Opposite side = a
Adjacent side = b
Hypotenuse side = c
From Pythagorean theorem;
c² = a² + b²
When a = 7, b = 24 and c = 25
25² = 7² + 24²
625 = 49 + 576
625 = 625
This ultimately implies that, the square of the hypotenuse of a right angle triangle is equal to the sum of the square of its opposite and adjacent sides according to Pythagorean' theorem.

(3)(c) + 43 ≥ 100
Step-by-step explanation:
Given:
Total number of friends = 3 friends
Number of card already have = 43
Total number of card at least want to collect = 100
Find:
Inequality
Computation:
Assume;
Same number of card each friend collect = c
Total number of card at least want to collect ≤ (Total number of friends)(Same number of card each friend collect) + Number of card already have
Total number of card at least want to collect ≤ (3)(c) + 43
100 ≤ (3)(c) + 43
(3)(c) + 43 ≥ 100

Answer:
51°
Step-by-step explanation:
The angles where the expressions are given are a linear pair, so total 180°.
(3x +15) +(10x +9) = 180
13x = 156 . . . . . . . . . . . . . . . subtract 24, collect terms
x = 156/13 = 12
Then the acute angle is ...
3x +15 = 3(12) +15 = 36 +15 = 51
The stairs make an angle of 51° with the basement floor.
_____
Additional comment
Building code requires the rise to be not more than 8 and the run not less than 9, so the maximum angle is about 41.6°. A 51° staircase would not meet code.
