We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
Answer:
Sister Are Like That Sometimes, Give her Time!
Step-by-step explanation:
Bigger siblings- especially girls- love their private time. If your sister seems annoyed, I suggest you just walk away. If she gets upset, agree with her argument. As a bigger sister myself, sometimes we just want nothing more than to be alone. Have you told your parents about this? Siblings need a reminder that they aren't always in charge. Tell your sister that you appreciate her, and that if she ever needs help going through anything, you're there for her. I understand this isn't the easiest, but that's how you can better connect with her.
5 + 5 + 5 + 5 equals 550 lgjf8654
3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7
Answer:
A. b+2(b+2b)
b + 2b + 4b = 7b
B. 3b + b = 4b
C. 2(2b) = 4b
None of them are equal to 9b
