-x/2 + 4 > = 6
-x/2 > = 6 - 4
-x/2 > = 2...multiply both sides by -2
x < = -4
_________________________________________
x + 3/2 < 7/4
x < 7/4 - 3/2
x < 7/4 - 6/4
x < 1/4
Answer: options A, B and C are correct
Step-by-step explanation:
Ray's daily pay,P in dollars is given by the function, p(h) = 10h with h representing the number of hours that he worked on that day. If he worked c hours on Thursday and this is 3 hours more than he worked on Friday, then the following statement is true. We substitute c and c-3 for Thursday and Friday into the given function, p(h) = 10h
A) 10c -3 represents Ray's pay in dollars on Friday.
B) 10c represents Ray's pay in dollars on Thursday.
C) p(c ) - p(c-3) represents how much more Ray's pay was on Thursday than on Friday
Answer:
(3, 3 )
Step-by-step explanation:
Given the 2 equations
3x - y = 6 → (1)
6x + y = 21 → (2)
Adding the 2 equations term by term will eliminate y, that is
(6x + 3x) + (y - y) = (21 + 6), that is
9x = 27 (divide both sides by 9 )
x = 3
Substitute x = 3 into either (1) or (2) and solve for y
Using (2), then
(6 × 3) + y = 21
18 + y = 21 ( subtract 18 from both sides )
y = 3
Solution is (3, 3 )
Complete Question
We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation
E= 17/20 D
a) How many euros have the same value as 1 U.S. Dollar? euros
b) How many U.S. Dollars have the same value as 1 euro? dollars
Answer:
a) 0.85 euros
b) 1.18 dollars
Step-by-step explanation:
The equation is given as:
E= 17/20 D
a) How many euros have the same value as 1 U.S. Dollar? euros
E = 17/20D
D = 1 dollar
Hence:
E = 17/20 × 1
E = 0.85 euros
b) How many U.S. Dollars have the same value as 1 euro? dollars
E = 17/20D
E = 1 euro
1 = 17/20D
D = 1 ÷ 17/20
D = 1 × 20/17
D = 1.1764705882 dollars
D = 1.18 dollars
