Find the error in the solution, and then solve it correctly.
7x + 12 + 3x = 8
7x + 12 = 5
7x = -7
x= -7/7
We could find the error first, but if we solve the equation, we can compare our answers to find the error. So,
7x + 12 + 3x = 8
10x + 12 = 8
10x = -4
x = -4/10
x = -2/5.
When we compare the two, we see that our second line is vastly different, and we can easily isolate the mistake, finding that it occurs when they disregard the variable in the 3x term and subtract 8 by 3 rather than combining the terms 3x and 7x together.
Answer:
x=-4/10 = -2/5
Step-by-step explanation:
7x+12+3x=8
(7x+3x) =8-12
10x=-4
x=-4/10
x= -2/5

Find the measure of x
Answer:
B
Step-by-step explanation:
The angle in a semicircle is 90° , then
x = 180° - (90 + 47) = 180° - 137° = 43° → B
Answer:
B. 43
Step-by-step explanation:
ignore the other triangle with the y angle. it is just there to confuse us.
the main information is given already by the main triangle with the angles x and 47 degrees.
because it's baseline is the diameter of a circle, and its top point is also on the circumference of the same circle.
all triangles that can be inscribed into a circle that way are by definition right-angled triangles.
so, the angle at the top point is actually 90 degrees.
and as we know, the sum of all angles in a triangle is always 180 degrees, we can simply calculate :
180 = 90 + 47 + x = 137 + x
x = 43 degrees
that's it.
If you rolled a die, what is the probability that you would roll a 3 or a 9? Give your answer as a simplified fraction.
P(3 or 9) =
Answer: P (3 or 9) = 1/6
Step-by-step explanation:
Concept:
Here, we need to know the idea of probability.
Probability is a measure of the likelihood of an event to occur.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
The numbers on a dice: 1, 2, 3, 4, 5, 6
Total numbers = 6
Number of 3 = 1
Number of 9 = 0
P (3 or 9) = Favorable / Total (refer to the attachment below)
P (3 or 9) = (1 + 0) / (6)
P (3 or 9) = 1 / 6

Answer:
A
Step-by-step explanation:
The inscribed angle IJK is half the measure of its intercepted arc, so
arc IK = 2 × 75° = 150°
The 3 arcs sum to 360° , then
arc IJ = 360° - (150 + 110)° = 360° - 260° = 100° → A
divide a sum of rs 1110 between A,B and C so that for every rs 8 given to A,B may get Rs 5 and for every Rs 7 given to B ,C may get rs 4
In this question, an amount is divided between three parts. From this, relations between the variables are used to find the amount corresponding to each part.
Sum of 1110 between A, B and C:
This means that:
[tex]A + B + C = 1110[/tex]
For every rs 8 given to A,B may get Rs 5
This means that:
[tex]\frac{A}{B} = \frac{8}{5}[/tex]
And thus:
[tex]5A = 8B[/tex]
[tex]A = \frac{8B}{5}[/tex]
For every Rs 7 given to B ,C may get rs 4
This means that:
[tex]\frac{B}{C} = \frac{7}{4}[/tex]
And thus:
[tex]7C = 4B[/tex]
[tex]C = \frac{4B}{7}[/tex]
Amount of B:
Replacing into the original equation:
[tex]A + B + C = 1110[/tex]
[tex]\frac{8B}{5} + B + \frac{4B}{7} = 1110[/tex]
[tex]\frac{56B + 35B + 20B}{35} = 1110[/tex]
[tex]111B = 1110*35[/tex]
[tex]B = \frac{1110*35}{111}[/tex]
[tex]B = 350[/tex]
Amounts of A and C:
A and C are given as functions of B, so:
[tex]A = \frac{8B}{5} = \frac{8*350}{5} = 560[/tex]
[tex]C = \frac{4B}{7} = \frac{4*350}{7} = 200[/tex]
Thus:
The amount given to A is of Rs 560, to B is of Rs 350 and to C is of Rs 200.
For another problem involving divisions given ratios, you can check https://brainly.com/question/23857756.
A, B and C receive RS. 560, RS. 350 and RS. 200, respectively.
In this problem, we must translate the sentences into mathematical expression. Please notice that systems of linear equations are resoluble if the number of formulas equals the number of variables. In other words, we must have three linear equations for three variables:
1) Divide a sum of RS 1110 between A, B, C:
[tex]a + b + c = 1110[/tex] (1) Var: 3, Eqs: 1
2) So that for every RS 8 give to A, B may get RS 5:
[tex]\frac{a}{b} = \frac{8}{5}[/tex]
[tex]5\cdot a - 8\cdot b = 0[/tex] (2) Var: 3, Eqs: 2
3) And for every RS 7 given to B, C may get RS 4:
[tex]\frac{b}{c} = \frac{7}{4}[/tex]
[tex]4\cdot b -7\cdot c = 0[/tex] (3) Var: 3, Eqs: 3
Now we solve the resulting system, the solution set of the system is:
[tex]a= 560[/tex], [tex]b = 350[/tex], [tex]c = 200[/tex]
A, B and C receive RS. 560, RS. 350 and RS. 200, respectively.

A man was traveling by air is allowed a maximum of 20kg luggages .The man has four bags weighing 3.5kg ,15 kg ,2kg and 1.5kg .Find excess weight of his luggage. 2 . Express the excess weight as a percentage of his maximum weight allowed.
Answer:
See explanation
Step-by-step explanation:
Maximum weight = 20 kg
Bag 1 = 3.5kg
Bag 2 = 15 kg
Bag 3 = 2kg
Bag 4 = 1.5kg
Total weight of bags = 22 kg
Excess weight of his luggage = Total weight of bags - Maximum weight
= 22 kg - 20 kg
= 2 kg
Express the excess weight as a percentage of his maximum weight allowed = excess weight / maximum weight × 100
= 2/20 × 100
= 0.1 × 100
= 10%
Express the excess weight as a percentage of his maximum weight allowed = 10%
A taxi fare is $3 and then $0.40 for every kilometre. A taxi fare is $9 . How far has the taxi travelled?

Answer:
0.249
Step-by-step explanation:
tan(theta) = opposite / adjacent (according to the SOH CAH TOA rule), which effectively means y/x in this case.
So -0.242 / -.970 ≈ 0.249
Other explanation:
On a unit circle,
y = sin(θ)
and
x = cos(θ).
And since, tan = sin/cos, tan(θ) = y/x. You y and x are given, so calculating tan is a matter of dividing them.

I was told that 3x- was -12 but I can’t understand how they got -12:/
Answer:
6
Step-by-step explanation:
They got 3x-12 because they took
3(x - 4)
and they distrubuted the 3 to the numbers in parenthesis,
how they did this was they multiplied 3 by x and got 3x then they kept the subtraction sign that is in the parenthesis. Then they multiplied 3 by the 4 and got 12.
then the equation was 3x - 12/2 = 6
Answer:
x=8
Step-by-step explanation:
[tex] \frac{3(x - 4)}{2} = 6[/tex]
Multiply 3 by what's in the bracket
[tex] \frac{3x - 12}{2} = 6[/tex]
Multiply through by the LCM of all the denominators
[tex] \frac{2(3x - 12)}{2} = 2 \times 6[/tex]
=The numerator 2 will cancel the denominator 2
[tex]3x - 12 = 12[/tex]
Grouping like terms
[tex]3x = 12 + 12[/tex]
Dividing both sides by 3
[tex] \frac{3x}{3 } = \frac{24}{3} [/tex]
[tex]x = 8[/tex]
