Answer:

n=2

Step-by-step explanation:

4(5n-7)=10+2

1) First, distribute (multiply out 4)

20n-28=10+2

2) Combine like terms (add 10 and 2)

20n-28=12

3) Isolate the variable (Add 28 to 12)

20n=40

4) Isolate the variable (Divide by 20)

n=2

5x-1/5=7/3 <br> Find The LCD That would eliminate the fractions
photoshop1234 [79]

Answer:

x=\frac{7}{15}

Step-by-step explanation:

5x-\frac{1}{5} =\frac{7}{3}

5x - \frac{3}{15}  = \frac{35}{15}

5x - \frac{3}{15}  + \frac{3}{15} = \frac{35}{15}  + \frac{3}{15}

5x=\frac{35}{15}

\frac{5x}{5} } =\frac{\frac{35}{15}}{5}

x=\frac{7}{15}

Factor the polynomial.
mrs_skeptik [129]
The coefficients here are 4, 32, and -24. The GCF of these values is 4.
As for the variables, the values are x^7, x^5, and x^4. The GCF is x^4
To factor this expression take out 4x^4 from each of the terms.
Coefficients should be divided by four and exponents should be subtracted by 4 since they have the same base (x).
The answer here is A.

Serious answers only please !! 20 points as well as brainliest for correct answer!!
Gre4nikov [31]

Answer:

Measure of angle A = 55°.

Step-by-step explanation:

From the picture attached,

\frac{AC}{LN}=\frac{BC}{LM}

\frac{10}{5}=\frac{8}{4}

2 = 2

Corresponding sides of the given triangles ΔACB and ΔNLM are proportional.

Therefore, ΔACB ~ ΔNLM.

m∠A = 180° - (90° + 35°) [By triangle sum theorem]

         = 180° - 125°

         = 55°

Measure of angle A is 55°.
