Answer:
x = 17/2 = 8.500
Step-by-step explanation:
Equation at the end of step 1 :
2 • (x - 5) - 7 = 0
Step 2 :
Equation at the end of step 2 :
2x - 17 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 2x-17 = 0
Add 17 to both sides of the equation :
2x = 17
Divide both sides of the equation by 2:
x = 17/2 = 8.500
So start:44 3/8 end: 45 1/4
so 44 3/8+x=45 1/4
subtract 44 3/8 from both sides
x=grow=45 1/4-44 3/8
so convert to fractions
45=180/4
45 1/4=181/4
44=352/8
44 3/8=355/8
181/4=362/8
x=362/8-355/8=7/8 inch he grew
Answer: y=4x-2 and y=4x+3
F(x) = x^3 - 2x^2 - 6x + 12 = 0
lets try substituting some of the factors of 12:-
f(2) = 8 - 8 -12+12 = 0 So one zero is x = 2 Answer
Dividing f(x) by (x - 2) we get:-
x^2 - 6 so the other 2 zeros are sqrt6 and - sqrt6 or 2.45 and -2.45 to the nearest hundredth Answer
Answer:
85%
Step-by-step explanation:
If she got 3 wrong then it means she got 20-3 right, so she got 17 questions right.
From there we get the fraction: 17/20
To make the a percentage we times both the top and bottom by 5 (because 20 x 5 = 100)
By doing that we get 17x5/20x5
= 85/100
That is equal to 85%
