Answer:
D. 1/3^3
Step-by-step explanation:
Divide 3/3 as usual and get 1.
When dividing exponents, you are actually subtracting them. 5-8 = -3.
D is the answer because positive exponents in the denominator of the fraction is the same as a negative exponent in the numerator.
The given system of equations is :
y=2x+14 ...(1)
−4x−y=4 ... (2)
We can solve the above system of equation by method of substitution. Frm equation (1) we have y=2x+14. So, first step is to substitute 2x+14 for y in equation (2). Hence,
-4x - (2x + 14) = 4
-4x - 2x - 14 = 4
- 6x -14 = 4 By combining the like terms.
-6x - 14 + 14 = 4 + 14 Add 14 to each sides of the equation.
- 6x = 18
Divide each sides -6.
x = -3.
Next step is to plug in x=-3 in equation (1) to get the value of y. Therefore,
y = 2(-3) + 14
= -6 +14
= 8
So, y=8.
Answer:
no
Step-by-step explanation:
you basically divide or multiply something.
say you divide 2 for 8:6, divide 2 by both #s. 8:6 would then have the equivalent ratio of 4:3
hope it helps!
22 1/2= 6 3/8+ 3 1/4+ x
22 1/2= 6+3(3/8+1/4)+x
22 1/2= 9 (3/8+2/8) +x
22 1/2= 9 5/8 +x
22 1/2 -9 5/8 =x
22-9(1/2-5/8)=x
13(4/8-5/8)=x
13 (-1/8)=x
12 7/8
