It would be 3,600 - 30 = 3570
Answer:
7/4 + 9/-5 =
Since the denominator of the second fraction is negative the sign will change from negative to positive
We will get
7/4 - 9/5
First find the LCM
LCM of 4 and 5 is 20
7/4 - 9/5 = 5(7) - 4(9)/ 20
Simplify
We get
35 - 36/20
= -1/20
Hope this helps
Answer:
x = 3, y = -2
Step-by-step explanation:
Solving the bottom equation for y, we have y = 4 - 2x. Substitute that into the top equation, and solve for x.
4x - 3(4 -2x) = 18
4x - 12 + 6x = 18
10x - 12 = 18
10x = 30
x = 3
From this, we have y = 4 - 2(3) = 4 - 6 = -2
Possible Answers:
1. b = 1.5
2. b = 20
3. b = 4
STEP-BY-STEP:
1. -12 ÷ -8
2. b + 20 = 8
3. b + -12 = -8

Please mark me as brainliest.
This took about 10 minutes to figure out, and write the equations, because I had to re-figure out how I got the original answers.
