Answer:

Step-by-step explanation:

add 12 to both sides to get x = 19

12 + 12 = 0 since your getting rid of the constants and 12 + 7 = 19 so x = 19

Use the opposite operation in which its formed in

For example 3x = 18

you would have to multiply 3 by x right? So the opposite operation of that is divide by 3 since you dont know the value of x so do the known value which is the number 3 once you divide 18 by 3 you get 6 so put 6 on the right side and keep the equal sign between them to get x = 19.

Clara has a purse in the shape of a trapezoid the top of the purse measures 22 cm while the bottom of the part measures 36 cm if

pashok25 [27]

The height of purse which is in trapezoid shape is 26 cm

Solution:

Clara has a purse in the shape of a trapezoid

The area of trapezoid is given by formula:

$Area = \frac{a+b}{2} \times h$

Where,

"h" is the height

"a" and "b" are the parallel sides length

From given,

Area = 754 cm

a = 22 cm

b = 36 cm

h = ?

Substituting the values in formula,

$754 = \frac{22+36}{2} \times h\\\\754 = \frac{58}{2} \times h\\\\Simplify\ the\ above\ expression\\\\754 = 29h\\\\Divide\ both\ sides\ of\ equation\ by\ 29\\\\h = 26$

Thus height of purse which is in trapezoid shape is 26 cm

determine The length of the circular arc of a circle with a radius of 49 cm subtended by a central angle of 135°

Katena32 [7]

Given:

Length of the circular arc with circle radius=49cm

θ=135°

Now,

Length of arc = θ/360°×2πr

49=2× 22/7×r×135°/360°

49×20×7/3×22×2

51.96cm

Answer:

It can be represented by the expression 2r, or “two times the radius.” So if you know a circle's radius, you can multiply it by 2 to find the diameter; this also means that if you know a circle's diameter, you can divide by 2 to find the radius. Find the diameter of the circle.
