Let f be the height of the fir trees
Let p be the height of the pine trees

We know from the problem that
f + p = 21  and 4f = 24 + p
rearrange the 2nd equation to get p = 4f - 24 and substitute into the other equation

so...
f + 4f - 24 = 21
5f - 24 = 21
5f = 45
f = 9 - height of the fir tree

substitute back into the 1st equation
9 + p = 21
p = 12 - height of the pine tree

The question is an illustration of a division model.

The boxes will be completed with: 1650, 231, 50 and 7

The expression is represented as:

\mathbf{1881 \div 33}

Express 1881 as 1650 + 231.

\mathbf{1881 \div 33 = (1650 + 231) \div 33}

Split

\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}

Evaluate each division

\mathbf{1881 \div 33 = 50 + 7}

\mathbf{1881 \div 33 = 57}

The above illustration means that, the boxes will be completed with the following numbers

  • 1650
  • 231
  • 50
  • 7

See attachment for proper illustration

I've already saved $68 for the $200 video game system. How many hours does raj need to work to earn the remainder of the money h
gladu [14]

Total amount needed for the video game = $200

Total amount of money saved = $68

Amount of money that is needed to be saved = 200-68  =132

So raj needs to work additional hours in order to earn the remaineder$132 for the video game

Hourly wage = $5.5

So, number of hours that Raj needs to work to earn $132 = $132/5.5 = 24 hours

Number of hours that Raj needs to work to earn the remainder of the money  = 24 hours
