Answer:
y divided by 6 1/4 = 11 3/4
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
y divided by 25/4 = 47/4
Next, multiply both sides by 25/4:
y divided by 25/4 x 25/4 = 47/4 x 25/4
The 25/4's on the left side of the equation cancel each other out, leaving you with:
y = 47/4 x 25/4
Multiply 47 x 25 and keep the same denominator:
y = 1,175/4
Divide and:
y = 293 3/4
Answer:
x>7
-6x+14< -28
-14. -14
-6x<-42
÷-6 ÷-6
x<7
switch signs because we divided by a negative number
x>7
Answer: x<-1
3x+28<25
-28 -28
3x<-3
÷3 ÷3
x<-1
Answer:
stuff
Step-by-step explanation:
i do not know
Answer:
I will go for a part the rest You can do by yourself
Step-by-step explanation:
Multiply the second equation to get same amount of x in both equations
2x=2-3y/2
multiply both equations by 2 to get rid of the fraction in second equation
4x+14y=34
4x=4-3y
subtract equation(2) from equation(1)
14y=30+3y
11y=30
y=30/11, x=-23/22
