Answer: (sec x – tan x)(csc x + 1).
Step-by-step explanation:
Find the number of pieces that aren't red, by subtracting the red from the total:
11 - 5 = 6 are not red.
The probability is the number of none red, over the total number of pieces: 6/11
Answer: $8 chicken $5 duck
Step-by-step explanation:
50x+30y=550
x=8
y=5
400+150=550
A = 2+3a +6
a-3a = 8
-2a = 8
a = -8/2 = -4
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
- 55+5x>100
- 5x>100-55 (Subtract 55 from each side)
- 5x>45
- x>9 (Divide each side by 5)
This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.
lmk if i made an error, hope this helps!!
