The answer is b. a triangle is equal to 180. to find x the equation would be 180= 3x-100+x-10+x-10 which is equal to 60. then sub 60 in to each equation. 3(60)-100=80, 60-10=50, 60-10=50
Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58
Answer:
Option (a) is correct.

Step-by-step explanation:
Given :A function has real zeros at x = −10 and x = −6 .
We have to find the function that has real zeros at x = −10 and x = −6.
Consider real zeros at x = −10 and x = −6.
x = - 10 ⇒ x + 10 = 0
x = - 6 ⇒ x + 6 = 0
Multiply both zeroes, we have,

Apply Distributive rule,

we have,

Simplify, we have,

Thus, 
Option (a) is correct.
4/10 means 4 tenths (4 times 1/10)
4/10
0.4
2/5

40%
Answer:

Step-by-step explanation:
Rewrite the equation into y=mx+b form by rearranging terms using inverse operations.
17x + 11y = 17 Subtract 17x from both sides.
-17x -17x
---------------------------
11y = 17 - 17x Divide by 11 on both sides.
y = 17/11 - 17/11 x
The slope intercept form is
