Answer:

1 5/8 is equal to 13/8

Step-by-step explanation:

-2X + 2 + 5X + 8?​

-2(5) + 2 + 5(5) + 8

-10 + 2 + 25 + 8

25

Answer: 25

Answer:

The answer would be 25.

Step-by-step explanation:

If x=5, that means:

-2(5)+2+5(5)+8

-10+2+25+8

-8+25+8

-17+8

25

Therefore, the value would be 25.

Answer: 100 99/100

Step-by-step explanation: add the 1/2 and 1/5 together by finding a common denominator(10). 1/2 would become 5/10 and 1/5 would become 2/10. 2/10 + 5/10 =7/10. now we're left with (7/10)^2 +3/10 x 5

to do (7/10)^2 you square the top and bottom to give you 49/100.

next we'll do 3/10 x 5 which would equal 15/10. so now all we have left to do is add 49/100 and 15/10. to do this we'll find a common denominator of 100. so well multiply the top and bottom by 10 to give you 150/100.

finally, 49/100 + 150/100 = 199/100 or as a mixed number, 100 99/100

Answer:

1[tex]\frac{99}{100}[/tex]

Step-by-step explanation:

I would start by turning the parentheses fractions into one fraction.

You could do binomial multiplication and get [tex]a^{2} +2ab+b^{2}[/tex] but it might take longer.

So I would just turn them into one fraction by finding the common denominator.

The common denominator here is 10

[tex]\frac{1}{5} (\frac{2}{2} )=\frac{2}{10}[/tex]

[tex]\frac{1}{2} (\frac{5}{5} )=\frac{5}{10}[/tex]

Now add

[tex]\frac{2}{10} +\frac{5}{10} =\frac{7}{10}[/tex]

Now apply: [tex](\frac{a}{b} )^{2} =\frac{a^{2} }{b^{2} }[/tex]

[tex](\frac{7}{10} )^{2} =\frac{7^{2} }{10^{2} } =\frac{49}{100}[/tex]

Now, multiplying the other fraction we get [tex]\frac{3}{10} (5)=\frac{15}{10}[/tex]

Now turn this into a fraction with denominator 100 to add the two fractions

[tex]\frac{15}{10} (\frac{10}{10} )=\frac{150}{100}[/tex]

[tex]\frac{49}{100} +\frac{150}{100} =\frac{199}{100} =1\frac{99}{100}[/tex]

There is also another method to add or subtract fractions without multiplying to get a common denominator in case you are interested:

[tex]\frac{a}{b}[/tex]±[tex]\frac{c}{d}[/tex]=[tex]\frac{ad+bc}{bd}[/tex]

a) 50+b=180 (supplementary angles)

b=180-50

b=130

b) b= 43° { vertically opposite angle}

A line can be drawn by joining the plot of the two given points

Reason:

Given points on the line are (-5, 3) and (-1, -1)

The slope, m, of the line is given as follows

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, we have;

[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]

The equation of the line in point and slope form is therefore;

y - 3 = -1·(x - (-5) = -x - 5

In slope and intercept form, we have;

y = -x - 5 + 3 = -x - 2

*SSQ*

Answer: 3.3

Step-by-step explanation: pythagorean theorem.

first we'll do the bottom triangle. a^2 + b^2 = c^2

a=3 and b=4

(3)^2 + (4)^2 = 9 + 16 = 25 which = c^2

to find c from c^2, square root the c^2 value. in this case it's 25. the square root of 25 is 5.

5 is now the base of the rectangle

now we can do pythagorean theorem again. except we'll switch it so it's c^2 - b^2 =a^2

c=6 and b=5

(6)^2 - (5)^2 = 36 - 25 = 11 = a^2

to find a we'll square root 11 which is just [tex]\sqrt{11[/tex]. approx. 3.3 to the nearest tenth.

We can use the Pythagorean theorem to solve for x.

But first, we have to find the value of 'a' (as I labelled in the diagram below). We could actually do all this in one step if we set it up correctly.

so    x = √(6² - a²)

&     a² = 3² + 4²

⇒  x = √[6² - (3² + 4²)]

    x = √(11)   or ≈ 3.3167
