Answer:
100
Step-by-step explanation:
100 is the correct answer
Answer:
The number is -100, Jill can think of something else, now.
Step-by-step explanation:
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
Answer:
x=-3y+8
Step-by-step explanation:
2x+6y=16
2x=16-6y
2x=-6y+16
x=-6/2y+16/2
x=-3y+8
You will use a2+b2=c2 (squared).The leg will represent the a2 or either b2 and the hypotenuse will be the c2.After filling in the variables you will then subtract the a2 which is the leg from the c2 which is the hypotenuse.And then you will factor it or square root it.If you square root it and it’s not a feasible answer then use the Christmas tree or birthday cake method to factor the answer and then you’ll have the value of b2 which is the unknown leg.
If they have opposite signs the point can be in either the second or fourth quadrants.
-x and +y is in the second quadrant
+x and -y is in the fourth quadrant.
