Answer: -1410
Step-by-step explanation:
Let's start by subbing in -4 for x

Now we can solve

Answer:
x=2.4
Step-by-step explanation:
2(x+1)+6=20-3x
We simplify the equation to the form, which is simple to understand
2(x+1)+6=20-3x
Reorder the terms in parentheses
+(+2x+2)+6=20-3x
Remove unnecessary parentheses
+2x+2+6=+20-3x
We move all terms containing x to the left and all other terms to the right.
+2x+3x=+20-2-6
We simplify left and right side of the equation.
+5x=+12
We divide both sides of the equation by 5 to get x.
x=2.4

Answer:
Option 3: transitive property
Step-by-step explanation:
The previous statements are
2. ∠2 ≅ ∠3 ⇒ 2. ver. ∠s theorem
And
5. m∠3 = m∠7 ⇒ 5. def. of congruent
So, The previous proved statement to make use of the transitive property reason or proof
∴ 6. m∠2 = m∠7 ⇒ 6. transitive property
Note: the transitive property states that: If a = b and b = c, then a = c.
Answer:
the two numbers are 21 and 12.
Step-by-step explanation:
Supplementary angles add to 180
they are x and y
x is 88
what is y
x+y=180
88+y=180
minus 88 from both sides
y=92
angle 4 is 92 degrees
