Answer:

x= 72/5

Step-by-step explanation:

Cross multiply

8/x=5/9

(8) * (9) = 5 * x (* equals multiply)

72=5x

Then Flip the equation

5x=72

Last, Divide both sides by 5

5x/5=72/5

and that’s it uwu✌️

Answer: angle V = 41 degrees (choice B)

======================================================

Explanation:

We're told that RS = ST = RT. This means triangle RST has all three sides equal to one another. This triangle is equilateral. Each interior angle is 60 degrees. This is because each angle is y, and y+y+y = 180.

Since each angle of triangle RST is 60 degrees, this means angle STR is 60 degrees.

Let z be the measure of angle UTV. Note how

(angleSTR)+(angleUTV) = 180

60+z = 180

z = 180-60

z = 120

Making angle UTV to be 120 degrees

------------------------------------

Now we can focus on triangle UTV since we have expressions for each interior angle

U = 4x-9
T = 120
V = 5x+6

Add up those angles, set the sum equal to 180, solve for x

U+T+V = 180

(4x-9)+(120)+(5x+6) = 180

9x+117 = 180

9x = 180-117

9x = 63

x = 63/9

x = 7

Use that x value to find the missing angle measures

angle U = 4x-9 = 4*7-9 = 28-9 = 19 degrees

angle V = 5x+6 = 5*7+6 = 35+6 = 41 degrees

Note how

U+T+V = 19+120+41 = 180

which helps confirm our answer.

HELP ME PLS!!!! asap!!!!

Answer: Calvin has 13 quarters.

Step-by-step explanation:

Let Calvin have x quarters.

therefore amount of Calvin = 0.25 x [ 1 quarter = $0.25 ]

Number of dimes for Sara = x

[ Given that number of dimes of Sara = number of quarters of Calvin

Amount of dimes for Sasha = 0.1x [ 1 dime = $0.1 ]

Amount of Sasha without dime = $1.95 [ given]

total amount of Sasha = 1.95 =+ 0.1x

Since amount of Calvin and Sasha is same therefore

0.25x = 1.95 +0.1x

0.25x -0.1x = 1.95

0.15x = 1.95

x = $\frac{1.95}{0.15}$

x = 13
