To the nearest ten, 829 would become <em><u>830</u></em> because the ones digit (9) is closer to 30 than it is to 20. So we would round up.
To round to the nearest hundred, we look at the tens and ones digit. 29 is less than 50 so we would have to round down to <em><u>800</u></em> instead of rounding up to 900.
Hope that helps :)
You factor the expression first leaving you with

Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with
z - 1
Answer:
Let x be the price of an adult ticket and y be the price of a youth ticket.
One family spends $134 on 2 adult tickets and 3 youth tickets so we can write: 2x+3y=134
Another family spends $146 on 3 adult tickets and 2 youth tickets so we can write: 3x+2y=146
We need to find y so we eliminate x. Multiply (1) by 3 and (2) by 2 to obtain (3) and (4): 6x+9y=402
6x+4y=292
Subtract (3) and (4) and solve for y: 5y=110
y=22→$22
Step-by-step explanation:
Answer:
B. 3x+5y≤20y≥1
Step-by-step explanation:
3 hours for a cap
x = cap
5 hours mittens
y = mittens
this is the amount of time
3x+5y <=20
she must do a pair of mittens
y>=1
