Find The Value Of X.

Answers

Answer 1

The triangle is equilateral, because all three angles will measure 60 degrees. This means that all three sides are equal, so:

7x + 19 = 11x - 89

4x = 108

x = 27

Answers

Answer: m > 9/5

Step by step

2 |−7m| + 8 > 4m + 26

= 2 × 7m + 8 > 4m + 26

= 14m + 8 > 4m + 26

= 14m > 4m + 26 − 8

= 14m > 4m + 18

= 10m > 18

= m > 18/10

= m > 9/5

Lin notices that the number of cups of red paint is always 15 of the total number of cups (0.2 of the total number of cups). She writes the equation r = 15t (r = 0.2t) to describe the relationship. Which is the independent variable? Which is the dependent variable? Explain how you know.

Answers

Step-by-step explanation:

The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.

She writes the equation r = 15t (r = 0.2t) to describe the relationship.

In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.

The number of cups of red paint is a dependent variable as it depends on the number of cups.

Mrs. Pena is buying 3 kinds of sandwiches for a family reunion. She buys x egg salad sandwiches at $3.10 each. She buys
y corned beef sandwiches at $3.35 each. Finally, she buys z cheese sandwiches at $2.85 each. Mrs. Pena spent a total of
$148.55 on the sandwiches. Which equation could be used to represent the situation?
A 3.10x + 3.35y + 2.85z = 148.55
00
(3.10 + 3.35 + 2.85)xyz = 148.55
(x + y + 2)(3.10 + 3.35 + 2.85) = 148.55
D
x + y + z = 148.55

Answers

The answer is A since there are x egg sandwiches that cost $3.10, y beef that cost $3.35 and z cheese sandwiches that cost $2.85, so buying one more of any of those would mean paying that amount a the number of times you buy it. So 2 of x is $3.10 x 2 = $

7. By selling a bicycle for * 2,850, a shopkeeper gains 14%. If the profit is reduced to 8%, then the selling price
will be
(a) 2,600
(b) 2,700
(c) 2,800
(d) 3,000
with steps
​

Answers

Correct option :[tex]= \color{plum}\bold{(b) \: 2,700}[/tex]Steps to derive answer :

Selling price of a bicycle = 2850

Profit percentage = 14%

We know that :

[tex]\color{plum}\tt{Cost \: \: price = \frac{Selling \: \: price \: \times \: 100}{100 \: \: + \: \: profit \: \%} }[/tex]

Then, the cost price of this bicycle :

[tex] = \tt \frac{2850 \times 100}{100 + 14} [/tex]

[tex] = \tt \frac{285000}{114} [/tex]

[tex] =\color{plum} \tt2500[/tex]

Thus, the cost price of this bicycle = 2500

In another scenario :

Profit percentage = 8%

Cost price of the bicycle = 2500

Then, Selling price will be equal to :

Let x be the selling price of the bicycle.

[tex] = \tt2500 = \frac{\: x \: \times 100}{100 + 8} [/tex]

[tex] = \tt2500 = \frac{100x}{108} [/tex]

[tex] =\tt 100x = 2500 \times 108[/tex]

[tex] = \tt100x = 270000[/tex]

[tex] =\tt x = \frac{270000}{100} [/tex]

[tex] =\color{plum}\tt x = 2700[/tex]

Therefore, the selling price with a profit of 8% will be = 2700

PLSSSSSS HELP I WILL MARK BRAINLIESTAfter Democratic triumph in the state elections of 1870 and aggressive federal intervention in 1871 and 1872, the formal Klan organization began to fade away. Local Klan-like groups continued to engage in racial and political terrorism, often calling themselves minutemen or rifle clubs, but they lacked larger organizational ties or even commonality of purpose. A romanticized memory of the first KKK legitimated their activities and, combined with the growing power of a Lost Cause mythology, contributed greatly to Georgians' acceptance of vigilante violence and lynching well into the twentieth century. By the 1890s, many men proudly claimed to have ridden with the Klan and thereby saved Georgia and the South from "Negro domination." This romanticized vision of the Klan was celebrated in popular novels and laid the foundation for the more openly organized Knights of the Ku Klux Klan, the second Ku Klux Klan, founded in Atlanta in 1915.Ku Klux Klan in the Reconstruction Era,Jonathan M.
