Answer:
its about 2
Step-by-step explanation:
Simplifying
7(3x + 5y) = 0
(3x * 7 + 5y * 7) = 0
(21x + 35y) = 0
Solving
21x + 35y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-35y' to each side of the equation.
21x + 35y + -35y = 0 + -35y
Combine like terms: 35y + -35y = 0
21x + 0 = 0 + -35y
21x = 0 + -35y
Remove the zero:
21x = -35y
Divide each side by '21'.
x = -1.666666667y
Simplifying
x = -1.666666667y
Answer:
See below.
Step-by-step explanation:
14.
12.5/2.5 = 5
15.
(i) [(-75)/15]/5 = -5/5 = -1
(ii) 13 / [(-2) + 1] = 13 / (-1) = -13
16.
(i) 39 + (-24) - 15 = 0
36 + (-52) - (-36) = 20
Answer: <
(ii) (-10) - 4 = -14
(-10) - (-4) = -10 + 4 = -6
Answer: <
17.
He reads 1/4 book in 1 hour.
He reads 1 book in 4 hours.
In 2 1/6 hours he reads:
(2 1/6)/4 part of the book = (13/6) / 4 = 13/24 part of the book
(i) 2/5 / 1 1/2 = 2/5 / 3/2 = 2/5 * 2/3 = 4/15
(ii) 7/3 / 2 = 7/3 * 1/2 = 7/6
Answer:
The y intercept is 100. that means she needs to pay a $100 base fee for the rental.
<span>(4 · 2^5) ÷ (2^3 · 1/16 )
</span>= (2^2 · 2^5) ÷ (2^3 · 2^-4 )
= (2^7) ÷ (2^-1)
= 2^8
