They are same side interior!! Not alternate, they’d be on opposite sides of the line
Answer: he collected 22 quarters and 8 fifty-cent pieces
Step-by-step explanation:
Given;
The total amount of money he is to collect is;
A = 20 - 10.50 = $9.50
Let x represent the number of quarter he collected.
Then the number of fifty-cent pieces he collected will be; 30-x
Therefore we can represent it with the equation below;
0.25x + 0.50(30-x) = 9.50
0.25x + 15 - 0.50x = 9.50
0.25x = 15-9.50
x = (15-9.50)/0.25
x = 5.50/0.25
x = 22
The number of fifty-cent is equal to;
30-x = 30-22 = 8
Therefore, he collected 22 quarters and 8 fifty-cent pieces
1/-3 or 4/-12, as long as you multiply or divide the numerator and the denominator with the same number the fraction will be equivalent. To get 1/-3 I divided 2 with 2 and -6 with 2.
Answer:
x = 17
<2 = 121
Step-by-step explanation:
We know that angle 1 and angle 3 form a linear pair, which means they add to 180
7x+2 + 3x+8 = 180
Combine like terms
10x+ 10 = 180
Subtract 10 from each side
10x+10-10 = 180-10
10x = 170
Divide by 10
10x/10 =170/10
x = 17
Angle 1 and angle 2 are vertical angles and vertical angles are equal
<1 = <2 = 7x+2 = 7(17) +2 =119+2=121
