Answer:

35+3 x+2 +52=180

35 +3x+6+52=180

93+3x=180

3x=87

x=87

---

x= 29

c=3[x+2]

substituding

c=3[29+2]

c=3x31]

c=93

35+93+52=180

Help please!!! I don't understand

zaharov [31]

$\left|x-\dfrac 12\right| = 3\dfrac 23\\\\\\\implies \left|x- \dfrac 12 \right| = \dfrac{11}3\\\\\\\implies x-\dfrac 12 = \dfrac{11}3 ~~~~~~~~~ \text{or}~~~~~~~ x - \dfrac 12 = - \dfrac {11}3\\\\\\\implies 2x -1 = \dfrac{22}3 ~~~~~~~~ \text{or}~~~~~~~~2x-1 =-\dfrac{22}3\\$

$\implies x =\dfrac 12\left(\dfrac{22}3 +1 \right) ~~ \text{or}~~~~~~~~ x = \dfrac 12 \left(1-\dfrac{22}3\right)}\\\\\\\implies x = \dfrac{25}6~~~~~~~~~~~~~~~ \text{or}~~~~~~~~ x=-\dfrac{19}6\\\\\\\implies x = 4\dfrac 16 ~~~~~~~~~~~~~~~ \text{or}~~~~~~~~x = -3\dfrac16$

Lines LM and QR are graphed on this coordinate plane. Which point is the intersection of lines LM and QR?

kvv77 [185]

The first number is the X coordinate and the second number is the Y coordinate.

Looking left to right the lines intersect at X = 1

Looking up and down they intersect at Y = -3

A rhombus and a triangle are equal in areas. if the base and height of the triangle are 24.8 cm and 5.5 cm respectively and the

ipn [44]

<h2>Given :-</h2>

Area of Rhombus = Area of Triangle

Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .

Length of one diagonal of the rhombus is 22 cm .

Length of other Diagonal

<h2>Solution :-</h2>

As we know that

Area of triangle = ½ × Base × Height

Area = ½ × 24.8 × 5.5
Area = 1 × 12.4 × 5.5
Area = 12.4 × 5.5
Area = 68.2 cm²

Area of rhombus = ½ × D1 × D2

68.2 = ½ × 22 × D2
68.2 × 2 = 22 × D2
136.4 = 22 × D2
136.4/22 = D2
6.2 = D2
D2=6.2

<h2>Hence :-</h2>

<h3>Other Diagonal is 6.2 cm.</h3>

What is 45% of 36 feet

marta [7]

100% of 36 ft= 36 ft
50% of 36 ft= 18 ft
5% of 36 ft = 1.8 ft
50%-5% or 18-1.8 ft gives you 16.2 ft

Which of the following is a point-slope equation of a line that passes through

Lesechka [4]

Answer:

Step-by-step explanation:

In order to write the equation of the line in point-slope form that goes through those points, we need to know the slope of that line. Therefore,

$m=\frac{-7-5}{4-10}=\frac{-12}{-6}=2$ So the slope is 2. Now we'll pick a point and use it to write an equation in point-slope form. I'll use the first point given to see if that's the one used in any of the answers : (10, 5)

y - 5 = 2(x - 10). That's choice B. Let's see, just in case there are 2 answers to this, what the equation would be using the other point (4, -7):

y - (-7) = 2(x - 4) and simplified:

y + 7 = 2(x - 4) is the other equation. Since that's not a choice, the only answer is B
