Answer:
C
Step-by-step explanation:
Take the coefficient of the linear term and divide it by 2
9/2
Then square it 81/4
That should either be added to the 11 or subtracted from the 15.
The answer is C
A
a) y+6x=5 if x= -1 then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5 subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13
B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4
So men to women=3 to 4
210 men
210 represents 3 units
wome=4
210=3 units
divide by 3
70=1 unit
multiply by 4 to find women
280=women
total workers=women+men
women=280
men=210
280+210=490
total =490
Answer:
42
Step-by-step explanation:
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(3)
A = 3
<u>Area of rectangle:</u>
A = bh
A = 11(3)
A = 33
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(3)(4)
A = 6
<u>Combined:</u>
3 + 33 + 6
42
