6 math books would be 126
5 English books would be 150
126+150=276
X+y=45
2x=3y
2(45-y)=3y
90-2y=3y
90=5y
y=18
x+y=45
x+18=45
x=27
The two numbers are 18 and 27
Answer:
x=7 because 25-4=21 and 21 ÷3=7
5=.1*x
divide both side by .1
5/.1=x
x=50 dollars
28°
a triangle = 180°
180°-140°= 40°
180°-68°= 112°
180°-112°-40°= 28°
