The equation is:
4x=64
x=64/4=16
answer: x=16º
2)Find y:
The equation is:
(2y)+(3y+5)=180
5y=180-5
5y=175
y=175/5
y=35
Answer: y =35º
Find the measure of each angle...
3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º
Answer: ∠a=46º.
4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º
Answer: ∠b=134º
5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º
Answer: ∠c=134º
6)∠d
112º+d=180º
d=180º-112º
d=68º
Answer: ∠d=68º
7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º
Answer: ∠e=48º
8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º
Answer: ∠f=132º

Let's check the distributive property first :
where ,
, and
are real numbers.
Now, to express 4x24 in the form , we just need to express 24 as a sum or subtraction.
Notice that we can express a 24 as a sum or subtraction in a number of ways:
1. 24-12=12, so 12+12=24
2. 24-10=14, so 10+14=24
3. 28-4=24, so 28-4=24
And so on...
Now let's use the distributive property:
1.
Since 24=12+12, we can express the same multiplication using the distributive property as:
2.
Since 24=10+14, we can express the same multiplication using the distributive property as:
3.
Since 24=28-4, we can express the same multiplication using the distributive property as:
As you can see, there are many ways to use the distributive property.
4 x 20 = 40
4 x 4 = 16
40 + 16 = 56
4 x 24 = 56

5x+20=3x+23
5x-3x=23-20
2x=3
x=3/2
5X + 20 = 3X + 23
5X - 3X = 23 - 20
2X = 3
X = 3/2
X = 1 1/2
