Answer:
4 feet 40 inches
Step-by-step explanation:
33 inches added to 4 feet 7 inches is <em>4</em><em> </em><em>feet</em><em> </em><em>40</em><em> </em><em>inches</em>
The working is as follows :
4 feet and 7 inches + 33 inches = 4 feet 40 inches
Step-by-step explanation:
2x-y= -1
x-2y= -8
eqn2*2=2x-4y= -16
eqn3- eqn1
-3y=- -15 y=5
2x-5= -1
2x=4 x=2
X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
−3/7×14/15×7/12×(−30/35)
=(−3/7×14/15)×(7/12×−30/35)
On further calculation, we get
=−2/5×−1/2
We get,
=1/5.
Property 1:
If a/b is a rational number and m is a non-zero integer then a/b =(a*m)/(b*m). In other words, we can say that the rational number remains unaltered if we multiply both the numerator and denominator with the same integer. Ex: 2/3 = 2*2/3*2 = 4/6, 2*3/3*3 = 6/9, 2*4/3*4 = 8/12.
