Answer:
x < - 8
Step-by-step explanation:
Given
3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides
3x + 3 + 11 < - 2x - 26
3x + 14 < - 2x - 26 ( add 2x to both sides )
5x + 14 < - 26 ( subtract 14 from both sides )
5x < - 40 ( divide both sides by 5 )
x < - 8
Answer:
x<-8
Step-by-step explanation:
3x+14<-2x-26(combine and distribute)
3x+14-14<-2x-26-14(subtract 14 from both sides)
3x<-2x-40(add 2x to both sides)
5x<-40(divide both sides by 5
x<-8(this is your final answer)

i need help its the triangle sum theorem
What are the values of x and y?
Answer
the one in the bottom right
Step-by-step explanation:
Answer:
option 2
Step-by-step explanation:
Using the cosine and sine ratios in the right triangle and the exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex]
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{20\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 60 ( divide both sides by 2 )
x = 30
--------------------------------------------------
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{20\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 20[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
y = 10[tex]\sqrt{3}[/tex]
does 36,84,91 make a right triangle?
Answer:
no
Step-by-step explanation:
a right triangle must have a 90° angle
Answer:
No, it will not make a right triangle.
Step-by-step explanation:
Use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
91 is the biggest number, so it would be 'c'. 36 and 84 will be 'a' and 'b'.
[tex]36^2+84^2=91^2\\\\1296+7056=8281\\\\\boxed{8352\neq 8281}[/tex]
The sides will not form a right triangle, since the final result is a contradiction.
Hope this helps.

Si una galleta de chocolate aporta un aproximado de 150 kcal y un viaje en bicicleta se quema por media hora se que mas 340 kcal cuanto tiempo necesita una persona en viaje para quemar 5 galletas
Answer:
Una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.
Step-by-step explanation:
De acuerdo con este problema, la cantidad de calorías que se quema es directamente proporcional al tiempo de viaje en bicicleta. Si sabemos que una galleta aporta 150 kilocalorías, entonces 5 galletas equivalen a 750 kilocalorías.
Por regla de tres simple calculamos el tiempo requerido para quemar 750 kilocalorías:
[tex]x = 30\,min \times \frac{750\,kcal}{150\,kcal}[/tex]
[tex]x = 150\,min[/tex]
Es decir, una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Write y = x2 – 18x + 52 in vertex form.
a
y = (x – 9)2 + 113
b
y = (x – 9)2 – 29
c
y = (x + 9)2 – 29
d
y = (x – 9)2 + 52
Answer:
b is the correct answer
y=a(x+n)^2+k
vertex: -b/2a 18/2=9
y=1(x-9)^2
k=9^2-18(9)+52= 81-162+52=-29
y=(x-9)^2-29

It is the fourth one because n could be any number on that red line because it’s is greater than -3
Answer:
The 4th option on the picture
Step-by-step explanation:
First, we can find -3 on the number line. Next, the inequality doesn't say n is greater than or equal to -3 (When you have a line under the greater sign, it means greater than or equal to), it says that n is greater than -3, so you don't fill in the dot. We know that to be greater than something, you point the line to the right side of the point (And we plot less than a point is to go left of the point), so we have all of the data to plot the line. The point is at -3 and isn't filled in and goes right of -3. Therefore, the answer is the 4th one.

Answer:

Step-by-step explanation:
A department store buys 400 shirts at a cost of $9,600 and sell them at a selling price of $30 each.
Answer: where’s the question? You didn’t write any questions:c
Step-by-step explanation:
The percent markup on each shirt is 25%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a department store buys 400 shirts at a cost of $9,600
So, the cost of each each shirt is 9600/400
= $24
Selling price of each shirt is $30
Now, markup price is 30-24=6
So, the percent markup
= 6/24 ×100
= 25%
Therefore, the percent markup on each shirt is 25%.

What is a reasonable estimate for the solution? O (1,-3/4) O (-3/4,1) O (-1,3/4) O (3/4,-1)
Answer:
See Explanation
Step-by-step explanation:
Your question is incomplete, as the equations or graph or table(s) were not given.
However, I'll give a general way of solving this.
Take for instance, the equations are:
[tex]y = \frac{4}{3}x - 1[/tex]
[tex]y = \frac{2}{3}x - \frac{1}{2}[/tex]
To do this, we start by equating both equations.
[tex]y = y[/tex]
i.e.
[tex]\frac{4}{3}x - 1= \frac{2}{3}x - \frac{1}{2}[/tex]
Collect Like Terms
[tex]\frac{4}{3}x - \frac{2}{3}x= 1 - \frac{1}{2}[/tex]
Take LCM
[tex]\frac{4x- 2x}{3}= \frac{2 - 1}{2}[/tex]
[tex]\frac{2x}{3}= \frac{1}{2}[/tex]
Cross Multiply
[tex]2x * 2 = 3 * 1[/tex]
[tex]4x = 3[/tex]
Make x the subject
[tex]x = \frac{3}{4}[/tex]
Substitute 3/4 for x in [tex]y = \frac{4}{3}x - 1[/tex]
[tex]y = \frac{4}{3} * \frac{3}{4} - 1[/tex]
[tex]y = 1 - 1[/tex]
[tex]y = 0[/tex]
Hence:
[tex](x,y) = (\frac{3}{4},0)[/tex]

Del sells his goods for £54.60 making a 9% loss how much did he pay for the good when he bought them?
Answer:
£54.65
Step-by-step explanation:
Del sells his goods for £54.60 making a 9% loss how much did he pay for the good when he bought them?
We are to find the cost price.
Loss = Cost price - Selling price
Percentage loss =
(Cost price - Selling price/Cost price) × 100
Percentage loss = 9% = 0.09
Selling price = £54.60
Cost price = x
Hence:
0.09 = x - £54.60/x × 100
0.09 = 100(x - £54.60)/x
Cross Multiply
0.09x = 100(x - £54.60)
0.09x = 100x - 5460
100x - 0.09x = 5450
99.91x = 54.50
x = 5460 / 99.91
x = 54.649184266
Approximately, x = £54.65
Therefore, the cost price = £54.65
