X = 8
y = 40

the two base angles are equal to each other so you would do 5x = 40 and solve for x

a triangle has 180 total degrees. 40*2 = 80
180 - 80 = 100
2y + 20 = 100
2y = 80
y = 40

Evaluate the expression for x=8. y=-0.1. and Z=4.6.<br>XZ-Y<br>XZ-Y

Elis [28]

Answer:

Step-by-step explanation:

write down the expression:

x*z-y

lets plug in the variables to evaluate the expression:

8*4.6-(-0.1)

36.8+0.1

Twelve less than 1/5 of a number is-7

cricket20 [7]

To solve this we have to work backwards.

start with -7 and add 12 to it to undo the first move

$- 7 + 12 = 5$

now take 5 and multiply by 5 to undo the last move

$5\times 5 = 25$

check our work:

$25 \div 5 = 5 \\ 5 - 12 = - 7$
