Ms. Peterson wrote the expression below on the chalkboard for her class. She asked the students to write an equivalent expression using no more than oneset of parentheses. 4(3x+5y+2z)+ 3(x-z)• Tom wrote 12x+20y+8z • Jenna wrote 5 (3x+4y+z)• Chris wrote 15x+20y-5zWhich, if any, of the three students wrote an expression that is equivalent to Ms. Peterson’s expression?

Answers

Answer 1

Answer: so first we solve
4(3x+5y+2z)+2(x-z)
fist we distribute
4 times 3x=12x
4 times 5y=20y
4 times 2z=8z
12x+20y+8z

then the second part

3(x-z)
3 times x=3x
3 times -z=-3z

3x-3z

combine

12x+20y+8z+3x-3z
group like terms
15x+20y+5z

so
tom:12x+20y+8z
this is only the first part so he is wrong

Jenna:5(3x+4y+z)
this is correct beccause if we multiply it we get
15x+20y+5z which is correct

chris: 15x+20y+5z is correct

Jenna and Chris are correct

The sum of two consecutive odd numbers is 156. Write an equation to determine the value of each number. Equation ________________________________. Solve the equation to determine the value of the larger of two numbers. Show your work. Answer ___________________.

Answers

The key is: two consecutive odd numbers.
Let's set the lower consecutive odd number as x.
That means the next odd number is x+2.
These two numbers must add up to 156.
x+x+2=156
2x+2=156
2x=154
x=77
Hope this helps :)

so consecutive odd number are 2 apart exg
odd number+2=odd number
1+2=3
so
x+x+2=156
subtract 2 from both sides
2x=154
divide by 2
x=77
x+2=79

the numbers are
77 and 79

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?

Answers

I don't know your options, but here are some facts:
-all their options are sandwiches, and they all cost 5 dollars.

-This means that they can buy 150/5=30 sandwiches. This will make them use the entire budget!

-I would suggest cutting the sandwiches in half, then everyone gets three halves!

and if you say r for roast beef and t for tuna, you can write:

r+t=30.

and you can distribute is freely as long as both are 0 or bigger and their sum is 30!

Answer:

D.The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
