Answer:
Angle 1= 147
Angle 2= 33
Step-by-step explanation:
(4a+7) + (a-2) = 180
4a+7+a-2=180
5a+5=180
5a=175
a= 35
plug in 35 for A to find measurements
4(35) +7 = 147
(35) -2= 33
Answer:
the ordered pair is (2,-1)
Step-by-step explanation:
We need to solve the system of equations using elimination method
12x - y = 25 eq(1)
9x + y = 17 eq(2)
Adding eq(1) and eq(2)
12x - y = 25
9x + y = 17
___________
21x = 42
x = 42/21
x= 2
Now, putting value of x in equation 1
12x - y = 25
12(2) -y = 25
24 -y = 25
Adding -24 on both sides
24 -y-24 = 25-24
-y = 25-24
-y = 1
Multiply both sides by -1
y = -1
the value of x = 2 and y = -1
So, the ordered pair is (2,-1)
1 pound = 16 ounces
multiply 16 times 3
your answer is 48 ounces total
