Answer:

x=-7

Step-by-step explanation:

3/4(x+21)=10 1/2

3/4x+15 3/4 = 10 1/2

(I put them in improper form)

3/4x+63/4 = 42/4

3/4x=-5.25

divide -5.25 by 3/4= x=-7

Simplify 4 n5 + 3.5 n5 + (-2.1 n5 ).

Alona [7]

Step-by-step explanation:

Step 1: Let's simplify step-by-step.

$4n^5 + 3.5n^5 - 2.1n^5$

$= 4n^5 + 3.5n^5 + -2.1n^5$

Step 2: Combine Like Terms:

$= 4n^5 + 3.5n^5 + -2.1n^5$

$= (4n^5 + 3.5n^5 + -2.1n^5)$

$= 5.4n^5$

Answer:

$=5.4n^5$

What’s the area of the shape

maxonik [38]

Answer:

19.63

Step-by-step explanation:

To find the area of a circle you can use the formula πr². The diameter (10) is twice the radius. So, the radius is 5. 5² = 25. 25x π =25π. Then you must divide by 4 because the shape is 1/4 a circle.

Hope this helps ;)

What is the equation of the following line? (-3, 1) and (0,0)

kakasveta [241]

Answer:

$y = -\frac{1}{3} x$

Step-by-step explanation:

We are given the following two points and we are to find the equation of the line which passes through them:

(-3, 1) and (0,0)

Slope = $\frac{0-1}{0-(-3)} =-\frac{1}{3}$

Substituting the given values and the slope in the standard form of the equation of a line to find the y intercept:

$y=mx+c$

$0=-\frac{1}{3} (0)+c$

$c=0$

So the equation of the line is $y = -\frac{1}{3} x$
