Answer:
The one you have selected is correct. Its the first one. y= -1/3x + 3
Answer:
<h2><u><em>
y = 3</em></u></h2>
Step-by-step explanation:
2 over 6 = Y over 9 Fraction equation is required
2/6 = y/9
y = 2/6 * 9
y = 3
check
2/6 = 3/9
1/3 = 1/3
the answer is good
Answer:
3 1/2 (three and one-half)
Step-by-step explanation:
Change 1 3/4 to 7/4.
Do keep, change, flip.
Keep the first fraction.
Change division to multiplication.
Flip 1/2 to 2/1.
Do 7/4 x 2/1 and get 14/4
Divide 14 by 4
You get 3.5 and you convert that to 3 1/2
Answer:
2(x + 1) = 10
x = 4
Step-by-step explanation:
Given:
2(x + 1) = 10
Solution:
Apply Distributive property
A*(B+C) = (A*B) + (A*C)
This means multiply 2 with x and 1
2*(x+1) = (2*x) + (2*1)
2x + 2 = 10
Use Subtraction property of equality
A = B, then A - C = B - C
Subtracting 2 from both sides:
2x + 2 - 2 = 10 - 2
2x = 8 Step 3
Use Division property of equality
It state that if you divide both sides of an equation by same nonzero number then the sides remain equal
Dividing both sides by 2
2x/2 = 8/2
x = 4
This means value of x is 4
Another method to solve this equation is:
2(x+1)=10
Use Distributive property
A*(B+C) = (A*B) + (A*C)
2*(x+1) = (2*x) + (2*1)
2*(x+1) = 2x + 2
Use commutative property
A + (-B) = (-B) + A
2x + 2 + (-2) = 2x + (-2) + 2
2x + 2 + (-2) = 10 + (-2)
2x + 2 - 2 = 10-2
2x = 8
Using division property
AX = B
AX / A = B / A
So
X = B/A
This becomes:
2x = 8
2x = 8.
Divide both sides by 2
2x / 2 = 8 / 2
x = 4
