Answer:
m∠A = 115°; m∠C = 50°
Step-by-step explanation:
∠A + ∠B + ∠C = 180
4x – 13 + 15 + x + 18 = 180 Combine like terms
5x + 20 = 180 Subtract 20 from each side
5x = 160 Divide each side by 5
x = 32
∠A = 4 × 32 – 13
= 128 – 13
= 115°
∠ C = 32 + 18
= 50°
Check:
115 + 15 + 50 = 180
180 = 180
Answer:
∠A = 115°
∠ C = 50°
Step-by-step explanation:
I took the test
The correct answer is B
420; 500
430; 500
420; 400
Answer:
430;400
Step-by-step explanation:
So tenth is the 2.. 5 makes it go to 3 430
hundred we look to change 4 so we look at tenths 2 is less than 5 so it stays the same 400
-6(-3)(-2)
First of all, a negative times a negative times a negative would end up as a negative, so we got that covered. Now all we need is the arithmetic part. 6 x 3 = 18, and 18 x 2 = 36
So you're final answer would be -36
Select one:
a. −9
b. −3
c. 3
d. 9
Answer:
3
Step-by-step explanation:
-x = 3 -4x + 6
Add 3 and 6.
-x = -4x + 9 * add 4x to itself and -x
+4x = 4x + 9 * -4x + 4x would cancel out so..
3x = 9 * divide
x = 3
Since 0 = 9 is not true, there is no value of x that satisfies the equation.
To find the value of x in the equation −x = 3 − 4x + 6, we need to isolate the variable x. We can start by combining like terms on the right side of the equation:
Next, we can add x to both sides of the equation to eliminate the -x term:
Since 0 = 9 is not true, there is no value of x that satisfies the equation. Therefore, the answer is None of the above.
