Answer 2

Answer: 5. -10y+18=-3(5y-7)+5y
do the parenthasees first
-10y+18=-15y+21+5y
group like terms (y with y and numbers with numbers)

-10y+18=-10y+21
add 10y to both sides and you get
18=21 which is false
so no solution

6. 8(t+2)-3(t-4)=6(t-7)+8
do the parenthasees
8t+16-3t+12=6t-42+8
group like terms
5t+28=6t-36
subtract 5t from both sides
28=t-36
add 36 to both sides
64=t

7. do the parenthasees first
20+8x-5=9x+21
add like terms
15+8x=9x+21
subtract 8x from both sids
15=x+21
subtract 21 from both sides
x=-6

8. distribute the parenthasees
12x-48+3=15
add like terms
12x-45=15
add 45 to both sides
12x=60
divide both sides by 12
x=5

There are 156 players on 13 teams. How many players are on each team.

Answers

There are 156 players on 13 teams. The no. of players on each team are :-
Therefore no. of player on each team = $(156)/(13) = 12$

you take the ammount of players, or the whole number which is 156 and then you devide it by the number of teams which is 13 and you get 12. so there are 12 players on each of the 13 teams for a total of 156 players

Can someone help me with this problem?In 2004, there were 3344 amusement parks and arcades. This decreased by 148 by 2009. Write and evaluate an expression to find the number of amusement parks and arcades in 2009

Answers

Number of amusement parks and arcades in 2004 = 3344

Decrease in the number of amusement parks from 2004 to 2009 = 148

So, the expression to calculate the total number of amusement parks and arcades in 2009 is 3344 - 148

Evaluating the expression we get the total number of amusement parks and arcades in 2009 as 3196

A box is filled with pennies, nickels, and dimes in a ratio of 2:3:4. If the total number of coins in the box is 1620, how many pennies are in the box

Answers

We could say that the number of pennies is 2x, nickels are 3x, and dimes are 4x. Adding all of them together, we get 2x+3x+4x=9x. We also know that 9x=1620 because the total amount of coins is 1620. Dividing by 9 on both sides we get x=180.
Pennies equal 2x= 2*180=360

A team of runners is needed to run 1/4 mile relay race. If each runner must run 1/16 mile. How many runners will be needed?

Answers

The correct answer is that there will be four runners needed. We canwork this out in the following way - if every runner runs a sixteenth ofa mile, then you need to work out how many sixteenths are in a fourth.You can establish this by converting the fraction so it becomesequivalent. 1/4 can be multipled by 4 to equal 4/16th, so therefore ifthere are four 16ths in one 1/16th, you will need four runners.

Answer:

you will need 4 runners
