Ms.Lee bought some Reese and a bag of chips. They cost $4.36 altogether. The chips cost $1.60 more than the Reese. How much did the Reese cost?
Answer: $1.38
Step-by-step explanation:
Let the value of the Reese be represented by x
Since the chip cost $1.60 more than the Reese, then the chip will be:
= x + 1.60
Since they cost $4.36 altogether, the value of the Reese will be:
x + (x + 1.60) = 4.36
2x + 1.60 = 4.36
2x = 4.36 - 1.60
2x = 2.76
x = 2.76/2
x = 1.38
The Reese cost $1.38
Answer:
1.36

If n + 7 = 10, evaluate 2n - 2
O 3
0 17
4
6
Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
[tex]n + 7 = 10[/tex]
Subtract 7 from both sides of the equation
[tex]n+7-7=10-7[/tex]
Simplify
[tex]n=3[/tex]
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.

Answer:
25.2
Step-by-step explanation:
isabels class has collected 90 cans in a food drive they plan to sort the cans into n bags, with an equal number of cans in each bag. write an expression to show how many cans there will be in each bag.
Answer:
cn=90, so long as c and n are whole numbers
Step-by-step explanation:
There are two variables in this equation you have here. One, n the number of bags, has already been given to you, because there can be any number of bags. The other, weĺl call it c, is the number of cans in each bag. Because there could be any number of bags, and the number of cans needed in each one is also a variable, you are left with more than one option. Any solution will work so long as the number of cans, c, per bag, n, is equal to the total, 90. There could be 9 cans in 10 bags, or 10 cans in 9 bags, or 15 cans in 6 bags or vice versa. The only way to define it for one answer is to have a set number of bags or cans per bag. Hope this helps!

Lauren invests money in an account paying simple interest. She invests $50 and no money is added or removed from the investment. After one year, she has $50.50. What is the simple percent interest per year?
Based on the amount invested and the amount it grew to, the simple interest rate is 1%.
Lauren invested $50 and got $50.50 after a year.
What is the Simple Interest rate?This rate can be found by the formula:
= (Difference in investment in year 1) / Amount invested x 100%
Solving gives:
= (50.50 - 50) / 50 x 100%
= 1%
In conclusion, the rate is 1%.

If the triangles are similar, what is the value of x?
A-x=16
B-x=38
C-x=42
D-x=55
Answer:
C- 42
Step-by-step explanation:
Answer:
C. x=42
Step-by-step explanation:
16 + 3x + y = 180
126 + 16 + y = 180
y = 38
16 + 3x + 38 = 180
54 + 3x = 180
3x = 126
x=42

Kelly met Jesse and Liza at the max for breakfast. The graph shows Kelly’s speed during her 12 minute drive
Answer:
D. [tex]-360\,\frac{km}{h}[/tex]
Step-by-step explanation:
Physically speaking, average acceleration ([tex]\bar a[/tex]), measured in kilometers per square hour, is defined by following formula:
[tex]\bar a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}[/tex] (1)
Where:
[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final speed, measured in kilometers per hour.
[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in hours.
The initial and final instants are, respectively:
[tex]t_{o} = 5\,min\times \frac{1\,h}{60\,min}[/tex]
[tex]t_{o} = 0.083\,h[/tex]
[tex]t_{f} = 9\,min \times \frac{1\,h}{60\,min}[/tex]
[tex]t_{f} = 0.15\,h[/tex]
If we know that [tex]t_{o} = 0.083\,h[/tex], [tex]v_{o} = 60\,\frac{km}{h}[/tex], [tex]t_{f} = 0.15\,h[/tex] and [tex]v_{f} = 36\,\frac{km}{h}[/tex], then the average acceleration of Kelly is:
[tex]\bar a = \frac{36\,\frac{km}{h}-60\,\frac{km}{h}}{0.15\,h-0.083\,h}[/tex]
[tex]\bar a = -358.209\,\frac{km}{h^{2}}[/tex]
