Answer:
D
Step-by-step explanation:
plug in (3,2) to see if it's a solution:
A) does -3(3) + 2 equal -7? yes
B) since 'A' is a solution then 'B' cannot be the answer
C) since (3,2) is a solution then 'C' cannot be the answer
plug in (2,-1) to see if it's a solution:
plug in (2,-1) to see if it's a solution:
-3(2) - (-1) equal -7? no, it equals -5
only (3,2) is a solution so the answer is D
3.15 /7 = 0.45
3.20/8 = 0.40
4.10/10 = 0.41
4.80/16 = 0.3
Answer is 1. 7 stamps worth 3.15

Then multiply
Answer: The fraction that makes up Democrats or Republicans is 49/50.
Step-by-step explanation: There are 100 senators in total. We have 46/100 representing the Democrats, and 13/25 representing the Republicans. The number representing the Republicans can be made into an equivalent fraction of the other simply by multiplying both numerator and denominator by 4 (in order to make the denominator the same, that is 100). Hence the fraction of Republicans is 52/100, while the rest are Independents. The independents are
Ind = 100 - (46/100 + 52/100)
Ind = 100 - 98/100
Ind = 2/100
{Total = 46/100 + 52/100 + 2/100}
{Total = 100/100}
However, the fraction of all senators that are Democrats or Republicans is derived as follows;
Dems = 46/100
Reps = 52/100
Total fraction = 46/100 + 52/100
Total fraction = 98/100
Total fraction = 49/50
Answer:
96 degrees
48 degrees
36 degrees
Step-by-step explanation:
Sum of interior angles in a triangle = 180
96 + 2x + x + 12 = 180
3x + 108 = 180
3x = 72
x = 24
2x = 2(24) = 48 degrees
x + 12 = 24 + 12 = 36 degrees
Answer:
96 degrees
48 degrees
36 degrees
