Answer: 3: $3.50 for one pound
4: The value of X is 10
5: P has the value of 2
Step-by-step explanation:
Answer: -130, - 129, - 128
Step-by-step explanation:
x + x+1 + x+2 = - 387
3x + 3 = - 387
3x = - 387 - 3
x = - 390/3
x = - 130
Answer:
B= 70, C= 50
Step-by-step explanation:
120=15x+5+22x+4
120=37x+9
111=37x
X=3
C: 15×3+5=50
B: 22×3 +4= 70
Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x,y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.
Answer:
x = 58
Step-by-step explanation:
Angle = 1/2(difference of intercepted arcs)
51 = 1/2 ( 160 -x)
Multiply each side by 2
2*51 = 160-x
102 = 160-x
Subtract 160
102 -160 = -x
-58 = -x
58 =x
