Answer:
x=9
Step-by-step explanation:
The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.
90+5x+5x=180
add the x values together
90+10x=180
subtract 90 from both sides
10x=90
divide both sides by 10
x=9
1 1 1 2
2 -3 1 -11 -2R1 + R2 → R2

0 0 1 -5/3
1 0 0 1/3
0 1 0 10/3
0 0 1 -5/3
Therefore, x = 1/3, y = 10/3, z = -5/3
Answer:
Step-by-step explanation:
i think its 1
Answer:
27
Step-by-step explanation:
Given expression :
1 + 24 + ( + 3) = 1
Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.
1 + 24 + ( + 3) - 1 = 0
Now, opening the bracket, we get
1 + 24 + 3 - 1 = 0
Negative 1 and positive 1 will get cancel
24 + 3 = 0
or 27
Therefore, the value of the numerical expression 1 + 24 + ( + 3) = 1 is 27.
Answer:
if you can split it in half its: $38.75
if you cant its: $46.50
Step-by-step explanation:
half:
1. 8+8+4=20
2. 15.50 divided by 2 = 7.75
3. 7.75 + 15.50 + 15.50 = 38.75
not half:
1. 8+8+8= 24
2. 15.50 times 3 = 46.50
