Warren paid $23.85 and received no change. He is a member and rented 2 lanes. how many pairs of shoes did he rent?
MEMBERS COST: $2.95
i'm not sure how much the lanes are, so i'm gonna list the prices of pairs of shoes so you can just add the price of the lanes and find the answer:
1 pair - 2.95
2 pairs - 5.90
3 pairs - 8.85
4 pairs - 11.80
5 pairs - 14.75
6 pairs - 17.70
7 pairs - 20.65
8 pairs - 23.60
(thats the highest amount of shoes he could get)

System of Equations Word Problems 3x3
1. Roy, Sally, and Jeff drive a total of 50 mi to work each day. Sally drives twice as far as Roy, and
Jeff drives 10 mi farther than Sally. Use a system of three equations in three unknowns to find
how far each person drives each day.
Answer:
Roy drives 10 miles Sally drives 20 miles and jeff drives 30 miles
Step-by-step explanation:
0 + 10 = Roy
Roy * 2 = Sally

(Choice E)
E
12+z=1712+z=17
Answer:
A, D and E
Step-by-step explanation:
A.
[tex]8 = z + 3[/tex]
Subtract 3 from both sides
[tex]8 -3 = z + 3-3[/tex]
[tex]5 = z[/tex]
[tex]z = 5[/tex]
B.
[tex]z - 1 = 6[/tex]
Add 1 to both sides
[tex]z - 1+1 = 6 + 1[/tex]
[tex]z = 7[/tex]
C.
[tex]20 = \frac{40}{z}[/tex]
Multiply through by z
[tex]z * 20 = \frac{40}{z} * z[/tex]
[tex]20z = 40[/tex]
Divide through by 20
[tex]\frac{20z}{20} = \frac{40}{20}[/tex]
[tex]z = 2[/tex]
D.
[tex]12z = 60[/tex]
Divide through by 12
[tex]z = 60/12[/tex]
[tex]z = 5[/tex]
E
[tex]12 + z = 17[/tex]
Subtract 12 from both sides
[tex]-12 + 12 + z = 17 - 12[/tex]
[tex]z = 5[/tex]
Hence:

Explain how you know the following system of equations has at most 2 solutions.
Solve the system algebraically. Show your work.
Solve the system by graphing.
y= 2x-1
y= x^2-9
Answer:
Step-by-step explanation:
Answer:
The said explanation is the answer.
Step-by-step explanation:
1) Graphing the first function (y = 2x-1). When the exponents of the variables are all 1, that is there are no square, cubes, etc. the equation is a line. Then it is enough to find two points to draw it. We can calculate two points assigning a number to x and calculating the corresponding number for y. For example, when x= 0 y= 2 times 0 -1 = -1. Then the line will pass from the point (0,-1). We need a second point, we can take x=1, then y = 2 times 1 -1 = 1. The line will pass from (1,1). We can mark the two points on the plane and draw the line from these two points.
2) Graphing the second function (y = x^2-9). A quadratic equation is of the form: ax^2+bx+c= 0. We have: y= f(x) -9. Set y=0. We have the quadratic equation: x^2-9=0. Using the algebraic identity: a^2-b^2=(a+b)(a-b). We can rewrite x^2-9=0 as x^2-3^2=0: [(x+3)(x-3)=0] - [(x+3)=0,(x-3)=0] - [x= -3, x= 3]. Hence, there are two solutions for x. So we have two x-intercepts: (-3,0) and (3,0). To find the y-intercept, set x=0: [(y = (0)^2-9=0)] - [(y=-9)]. Hence the y-intercept: (0,-9)
In conclusion, this system of equations at most has two real solutions, since two points of both functions intersect each other.
Here's the graph:

The cube root of 60 is 20
False, the actual cube root of 60 is 3.9.
The result can be shown in multiple forms. Exact Form: 3√60 60 3. Decimal Form: 3.91486764
Answer:
False
Step-by-step explanation:
The cube root of 60 cannot be simplified, as there are no factors to factor out of the equation. This makes the statement false.

Solve the following equation for g.
Rg = m + h²g
Answer:
g=m/R-h²
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
g=m/R-h²
Step-by-step explanation:
Rg = m+h²g
Rg-h²g=m
by transposing h²g to the other side of the equation it has acquired a negative sign.
after this you factorise the left side.
g(R-h²)=m
now you divide both sides of the equation by R-h². The reason for doing so is because you're trying to single out g.
g=m/R-h²
Bruce takes out a personal loan of $1,000 to go on a trip to Florida. His loan has an annual compound interest rate of 10%. The loan compounds once each year. When you calculate Bruce's debt, be sure to use the formula for annual compound interest. A = P (1+StartFraction r Over n EndFraction)nt Bruce borrowed $1,000 for his trip. If Bruce waits for five years to begin paying back his loan, how much will he owe? $1,251.10 $1,310.21 $1,610.51 $1,810.71
Answer: He will owe $1610.51 .
Step-by-step explanation:
Given: Loan amount (P)= $1,000
Rate of interest (r) = 10% = 0.10
Number of years (t)= 5 years
n= 1 (will pay once in a year)
Formula: [tex]A= P(1+\dfrac{r}{n})^{nt}[/tex]
[tex]A=1000(1+0.10)^5[/tex]
[tex]=1000(1.10)^5\\\\=1000(1.61051)\\\\ =1610.51[/tex]
Hence, He will owe $1610.51 .
Answer:
1610.51 $
