Plzz answer questions 1-8 plzz. only answer if you know it.

1)  $2
2)  29
3)  8
4)  $20
5)  $12
6)  4
7)  $8 8)  5

 1) The answer would be $2. You can solve this problem by setting an equation: 20= 7x+6. Subtract 6 from both sides and you get 14= 7x. After that, divide both sides by 7. 14 divided by 7 is two. The answer is 2.

2) The answer would be 29. You can answer this question by setting up the following equation:  x+x+2+x+4=93. For instance, you know that x is an odd number (example lets say its the number 1). The next consecutive ODD number would have to be 3 (following the example given), which can be represented by x+2 (1+2=3). Now, knowing this, the third number can be represented by the expression x+4 (1+4=5, which makes sense as the order of the numbers would now be 1,3,5- consecutive odd numbers). Apply this to the question:   x+x+2+x+4= 93 then becomes 3x+6 after combining like terms. This leaves you with 3x+6=93. Subtract 6 from both sides: 3x=87. Divide both sides by 3: x=29 (the smallest number as the other numbers would be 31 and 33 which you get by plugging in to x+2 and x+4). Finally, you can check your answer by adding all the numbers :-)

3) 8 notepads. The question states that Danielle had $35 and bought 1 magazine (worth $3) and some notepads (each worth $4). You can solve this question by setting up the following equation: 35= 3+4x. Subtract both sides by 3 and you get 32=4x. Divide both sides by 4: 8=x.

4) $20
5) $12
6) 4 candy bars
7) $8
8) 5 hours

 

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

Idon’t understand what you’re asking..
