The first container contains 200 mL. The second container contains 7/8 that much so the second container contains 200*7/8. The second container holds 175 mL. Together the containers contain 200+175 mL, so 375 mL in total.
A+b=-10
ab=-75
a=-75/b
-75/b + b = -10
-75/b + b²/b = -10b/b
b²+10b-75=0
(b+15)(b-5)=0
b+15=0 or b-5=0,
b= -15, a=5
Answer:
-4
Step-by-step explanation:
3-7= -4
Answer:
Step-by-step explanation:
it should add up to 360°
360=135 + 120 + 7x-64+5x-4+3x+31+4x+15+6x-8 (seems like too much huh)
360=225+25x ( much better just add the x terms and the constants together)
135 = 25x ( just subtract 225 from each side of the equation)
5.4 = x ( divide 135 by 25 )
