Find the value of x 3x+1=x+9

Ann [662]

Answer:

X = 4

Step-by-step explanation:

you just gotta subtract 1 from both sides in order to find what x equals. and from there you subtract x from both sides, any letter has an invisible 1 in front, so then you divide 2 from both sides. and you get x = 4

Help!!!!!!!!!!!!!!!!!!!

Marina CMI [18]

Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

radius = 57 cm height = 40 cm

area of a cylinder = π 57² cm² × 40 cm

= π (57² × 40) cm³

= π ( 57 × 57 × 40) cm³ 57x57 = 399 + 2850 = 3249

= π (3249 × 40) cm³

= 129969π cm³ π = 3.14

= 129969 × 3.14 cm³

= 408,074.4 cm³ < ----------------- Final Answer

State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used.

never [62]

Answer:

Triangles ABC and MNO are similar by SSS

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional

In this problem

If this problem the corresponding sides are

AB and MN

BC and NO

AC and MO

Verify if the corresponding sides are proportional

$\frac{AB}{MN}=\frac{BC}{NO}=\frac{AC}{MO}$

substitute the given values

$\frac{5}{7.5}=\frac{5}{7.5}=\frac{8}{12}$

$0.67=0.67=0.67$ ----- is true

When two triangles have corresponding sides with identical ratios , the triangles are similar by SSS Similarity

therefore

Triangles ABC and MNO are similar by SSS

Solve for x 73 =(9/10x)+19

Yuliya22 [10]

$73=(\frac{9}{10}x)+19$

To solve x:

1. Substract 19 in both sides of the equation:

$\begin{gathered} 73-19=(\frac{9}{10}x)+19-19 \\ \\ 54=\frac{9}{10}x \end{gathered}$

2. Multiply both sides of the ewuation by 10/9:

$\begin{gathered} 54\cdot\frac{10}{9}=\frac{9}{10}x\cdot\frac{10}{9} \\ \\ \frac{540}{9}=x \\ \\ 60=x \end{gathered}$ <h2>Then, the value of x is 60 (x=60)</h2>
