If you have to compare two shapes you basically count the number of shapes there are of each type then you say for example 6:4. If they ask you to give the number of shapes to the number of shapes there are you count all the shapes and then you count the shape they asked you to find and then you will get something like 4:15
Multiply by 3 in the first equation and then you can cancel out the +3y and -3y to get the x answer. After that, you can do the same with the y by multiplying -2 in the first equation to cancel out the +2x and the -2x. Do you understand?
Answer:
7· 5n + 55 ≥ 100 is required inequality
Step-by-step explanation:
Let he visit be theater x time
→ for new movie ticket
→55+7·5xn≥100
→7·5n+55≥100
Hence, 7· 5n + 55 ≥ 100 is required inequality
Answer:
x>7 or x ≤ -3
Step-by-step explanation:
Solving the 1st inequality
-6x +14 < -28 --------------- (Collect like terms)
-6x < -28 - 14
-6x < - 42 -------------------- (Divide both sides by -6)
Note: If you decide an inequality expression by a negative value, the inequality sign changes)
-6x/-6 > -42/-6
x > 7
Solving the 2nd inequality
9x + 15 ≤ −12 ----------- (Collect like terms)
9x ≤ −12 - 15
9x ≤ −27 ------------------(Divide both sides by 9)
9
9x/9 ≤ −27/9
x ≤ -3
Bring both results together, we get
x>7 or x ≤ -3
The final result is complex (i.e. can't be combined together).
