I need help finding the x

Mathematics
1 answer:
Sati [7]2 years ago
6 0

Answer:

x = 1/2 or .5

Step-by-step explanation:

JK = 7x + 2, KL = 5x + 4 and JL = 12

JK + KL = JL

Plug in the equations for the Lines

7x + 2 + 5x + 4 = 12

Combine like-terms

12x + 2 + 4 = 12

12x + 6 = 12

Subtract 6 from either side

12x + 6 = 12

      -6      -6

12x = 6

Divide either side by 12

12x / 12 = 6/ 12

x= 1/2 or .5

Billy is hiking in Colorado. He walks eastward four miles, then turns $60$ degrees northward and walks six miles. How far is he
nikklg [1K]

He is  2√19 miles far way from starting point.

Suppose Billy starts at point A, turns at point B, and ends at point D, as shown below.

If Billy turns 60◦ northward and walks six miles, then we can draw a 30 − 60 − 90 triangle whose hypotenuse is 6 miles

It follows that Billy traveled 6/2 = 3 miles eastward during these 6 miles, and that he traveled 3√3 miles northward during these 6 miles. In total, Billy traveled 4 + 3 = 7 miles  eastward and 3√ 3 miles northward.

By the Pythagorean Theorem, the distance from his starting point is q:

(7)2 + (3√3)2

=√49 + 27

= √76

= 2√19 .

4 (4b + 3) + 2b = 3 (6 - 11)
erma4kov [3.2K]
Solve for b?
1. Distribute “4(4b+3)” and “3(6-11)”
16b+12+2b=18-33

2. combine like terms
18b+12=-15
18b=-27
b=-27/18

3. simplify
b=3/2

Find the volume of the pyramid
podryga [215]

Answer:

88 cm^{3}

Step-by-step explanation:

Given 3 measurements 6,11,4

Assuming them to be length, width and height of pyramid

⇒

Length=  6 cm

Width= 11cm

Height= 4 cm

⇒

\text{Volume of a Pyramid}= \frac{Length \times Width \times Height}{3}

Therefore Volume of Given Pyramid

=\frac{6\times 11\times 4}{3} =\frac{264}{3} =88

⇒Volume of pyramid=88cm^{3}

lim x rightarrow 0 1 - cos ( x2 ) / 1 - cosx The limit has to be evaluated without using l'Hospital'sRule.
zaharov [31]

Answer with Step-by-step explanation:

Given

f(x)=\frac{1-cos(2x)}{1-cos(x)}\\\\\lim_{x \rightarrow 0}f(x)=\lim_{x\rightarrow 0}(\frac{1-(cos^2{x}-sin^2{x})}{1-cos(x)})\\\\(\because cos(2x)=cos^2x-sin^2x)\\\\\lim_{x \rightarrow 0}f(x)=\lim_{x\rightarrow 0}(\frac{1-cos^2x}{1-cos(x)}+\frac{sin^2x}{1-cosx})\\\\=\lim_{x\rightarrow 0}(\frac{(1-cosx)(1+cosx)}{1-cosx}+\frac{sin^2x}{1-cosx})\\\\=\lim_{x\rightarrow 0}((1+cosx)+\frac{sin^2x}{1-cosx})\\\\\therefore \lim_{x \rightarrow 0}f(x)=1
