Answer:
uhmm I need points, sorry.
Step-by-step explanation: ...
Rachel: 3 bracelets in an hour.
Oliver: 2 bracelets in an hour but has completed 5 bracelets
Rachel : y = 3x
Oliver : y = 2x + 5
Let x be the number of hours. y is the total number of bracelets made in x hours.
3x = 2x + 5
3x - 2x = 5
x = 5
It would take 5 hours for Rachel to have the same number of bracelet as Oliver.
Rachel: 3x = 3(5) = 15
Oliver: 2x + 5 = 2(5) + 5 = 10 + 5 = 15
Answer:
a = 16
Step-by-step explanation:
The altitude YB is at right angles to the base XZ , then
∠ YBZ = 90° , so
6a - 6 = 90 ( add 6 to both sides )
6a = 96 ( divide both sides by 6 )
a = 16
$505 . 11 times 23 =253 . 14 times 18=252. When you add them you get $505
