Find x<br><br> This is a kite from geometry

kolezko [41]

Answer:

x=6

Step-by-step explanation:

Solve for x.

5x-15 = 2x+3

(Move the 2x to the other side of the equation.)

3x-15= 3

(Move the 15 to the right side of the equation.)

3x=18

(Divide both sides by 3 to isolate the variable.)

x=6

Answer the following questions

Alex787 [66]

Answer:

1. $2 \frac{2}{7}$

2. $2 \frac{1}{3}$

3. $\frac{5}{12}$

4. $8 \frac{2}{3}$

5. $\frac{2}{3}$

Step-by-step explanation:

<h2> $1. \: \: 2 \frac{2}{3} \div 1 \frac{1}{6}$ </h2>

$\frac{8}{3} \div \frac{7}{6}$

$\frac{8}{3} \times \frac{6}{7}$

$8( \frac{2}{7} )$

$\frac{8 \times 2}{7}$

$\frac{16}{7}$

$2 \frac{2}{7}$

<h2> $2. \: \: 6 \frac{2}{3} \div 2 \frac{6}{7}$ </h2>

$\frac{20}{3} \div \frac{20}{7}$

$\frac{20}{3} \times \frac{7}{20}$

$\frac{1}{3} \times 7$

$\frac{7}{3}$

$2 \frac{1}{3}$

<h2> $3. \: \: 4 \frac{1}{6} \div 10$ </h2>

$\frac{25}{6} \div \frac{10}{1}$

$\frac{25}{6} \times \frac{1}{10}$

$\frac{5}{6} \times \frac{1}{2}$

$\frac{5}{6 \times 2}$

$\frac{5}{12}$

<h2> $4. \: \: 6 \frac{1}{2} \div \frac{3}{4}$ </h2>

$\frac{13}{2} \div \frac{3}{4}$

$\frac{13}{2} \times \frac{4}{3}$

$13( \frac{2}{3} )$

$\frac{13 \times 2}{3}$

$\frac{26}{3}$

$8 \frac{2}{3}$

<h2> $5. \: \: 3 \frac{3}{4} \div 5 \frac{5}{8}$ </h2>

$\frac{15}{4} \div \frac{45}{8}$

$\frac{15}{4} \times \frac{8}{45}$

$\frac{1}{4} \times \frac{8}{3}$

$\frac{2}{3}$

Can someone help me plz and thank u

alexandr402 [8]

Answer:

<A = 44

Step-by-step explanation:

A triangle is 180 degrees

(x+59) + (x+51) + 84 = 180 >> add everything on the left side

2x + 194 = 180 >> subtract both sides by 194

2x = -14 >> divide both sides by 2 to get x alone

x = -7

since you are finding A<, substitute

<A = x + 51

<A = (-7) + 51

<A = 44

I NEED HELP in this

Alexeev081 [22]

As the image is magnified by a factor of 1: 7(1/4)
= 1: (29/4)
= 4/29.

The length of x must've been also increased by a factor of 4/ 29.

Using this,
The scaled value of x will be,

3(4/29)
= 12/29 units.
