Answer:Domestic Stamps: 123
Foreign Stamps: 89
Step-by-step explanation:
So we have two equations
x - y = 34
x + y =212
Let's take the first equation and put it in terms of x
x-y+y= 34+y
x= 34 + y
Now that we have a value for x, substitute it into the second equation for x and solve for y.
(34+y)+y=212
34+y+y = 212
34+2y= 212
34-34+ 2y=212-34
2y= 178
2y/2=178/2
y= 89
Now that we know the value for y, we can substitute it into the first equation and solve for x.
x-89=34
X-89+89=34+89
X=123
Y= 89
X =123

Answer:
a = - 8
Step-by-step explanation:
A polynomial divided by factor (x - h) has a remainder given by f(h)
Here the divisor is (x - 2), thus f(2) gives the remainder, that is
2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder
8 + 8 - 14 + a = 4, that is
12 + a = 4 ( subtract 12 from both sides )
a = - 8
Answer:
55°
Step-by-step explanation:
Assuming you are looking for the angles and not the length of the sides, the remaining angle is 55°. All 3 angles have to equal 180°.
A+B+C=180
A+75+50=180
Subtract 75 and 50 from 180 to get:
A=55
Answer:
C. infinitely many solutions
Step-by-step explanation:
every point of the line (or lines) is a solution.
so, infinitely many.
