Answer: #20, x = 3
#21, x = 1/2
Step-by-step explanation:
#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1
3x + 11 = 4x + 8
<u>-3x -3x</u>
11= x + 8
<u> - 8 - 8</u>
3 = x
#21) 12x(5) = 6x + 9 + x + 10 + x + 7
60x =8x + 26
<u> -8x -8x</u>
52x = 26
divide both sides by 52
x = 1/2
Step-by-step explanation:
This is what it is equal to:
9×3x=27x
9×8=72
Therefore it will be:

Since its a right triangle, you can use a² + b² = c²
one of the legs is a and the other leg is b it doesn't matter which one because its addition and works the same way c needs to be the hypotenuse
so its a² + 48² = 50²
a² + 2304 = 2500
- 2304 -2304
a² = 196
√a² = √196
a = 14
Answer:
y=1/2+1
Step-by-step explanation:
1) Y2-Y1 over X2-X1
<u>9-5=4</u>
12-4=8
4/8 simplify the answer= 1/2
m=1/2
2) subtitute the simplification to one of the points.
y=mx+b
5=1(4)+b
5=4=b
1=b
y=1/2+1
