-2k = k - 7 - 8 whats the answer

Mathematics
1 answer:
emmasim [6.3K]3 years ago
4 0

Answer:

−2k=k−7−8

−2k=k+−7+−8

−2k=(k)+(−7+−8)(Combine Like Terms)

−2k=k+−15

−2k=k−15

Step 2: Subtract k from both sides.

−2k−k=k−15−k

−3k=−15

Step 3: Divide both sides by -3.

−3k

−3

=

−15

−3

k=5

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?
Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8             12

------   = -----------

x+4          2x+1


using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10

Find the equation of the line passing through the point (4,−1) that is parallel to the line 2x−3y=9 Find the slope of the line 2
AnnZ [28]

Answer:

Step-by-step explanation:

2x - 3y = 9

-3y = -2x + 9

y=\frac{-2}{-3}x + \frac{9}{-3}\\\\y=\frac{2}{3}x-3\\

Parallel lines have same slope.So,

Slope m = 2/3

(4 , -1)

Equation: y - y1 = m(x - x1)

y-[-1]=\frac{2}{3}(x - 4)\\\\y+1=\frac{2}{3}*x - \frac{2}{3}*4\\\\y+1=\frac{2}{3}x-\frac{8}{3}\\\\y=\frac{2}{3}x-\frac{8}{3}-1\\\\y=\frac{2}{3}x-\frac{8}{3}-\frac{3}{3}\\\\y=\frac{2}{3}x-\frac{11}{3}

b = -11/3

Prudence is creating a garden in her backyard. She wants it to be the shape of an equilateral triangle with sides of length 20 f
algol [13]

Answer:

The area of the triangular garden is 173\ ft^{2}  

Step-by-step explanation:

we know that

The equilateral triangle has three equal sides and three equal internal angles (the measure of each internal angle is 60 degrees)

The area of a triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(b)sin(C)

In this problem we have a equilateral triangle

therefore

a=b=20\ ft

C=60\°

substitute

A=\frac{1}{2}(20)(20)sin(60\°)

A=\frac{1}{2}(20)(20)\frac{\sqrt{3}}{2} \\ \\A=100\sqrt{3}\ ft^{2}\\ \\A=173\ ft^{2}
