Answer:Well, divide 50 from 70 to get your answer and if you want you can double check your work but whatever your answer is after you divide is your answer (mine was 1.4). Sorry my typing might sound weird or I got the wrong answer I am just tired.
Step-by-step explanation:
(x + 7) - (3x + 4) = x + 7 - 3x - 4 = (x - 3x) + (7 - 4) = -2x + 3
To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.
Ordered pairs :
A. (4,2)
B. (5,-2)
C.(0,-1)
D.(-3,1)
E. (2,7)
F. (8,4)
Answer:
A, B, F are solution to the inequality
Step-by-step explanation:
5x - y > 4
To obtain the pairs which are solution to the linear inequality ; we plug in each orders pair of values into the inequality :
A.)
(4,2)
5x - y > 4
5(4) - 2 > 4
20 - 2 > 4
18 > 4 - - - - - - - True
B.
(5, -2)
5x - y > 4
5(5) - (-2) > 4
25 + 2 > 4
27 > 4 - - - True
C.
(0, -1)
5x - y > 4
5(0) - (-1) > 4
1 > 4 - - - - - - - Untrue
D.
(-3,1)
5x - y > 4
5(-3) - 1 > 4
-15 - 1 > 4
-16 > 4 - - - - - > Untrue
E.
(2,7)
5x - y > 4
5(2) - 7 > 4
10 - 7 > 4
3 > 4 - - - - Untrue
F.
(8,4)
5x - y > 4
5(8) - 4 > 4
40 - 4 > 4
36 > 4 - - - - - - - True
