The cost of one pair of earing will be £8.59.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that four friends, each bought matching necklaces and two pairs of earrings the necklace was priced at 15.00 if the total bill for all 4 friends was 128.00.
The cost of one pair of earing will be,
£128-£15-£15-£15-£15= £68
Number of pairs of earing,
2x4=8 pairs of earrings
The cost of one pair of earrings is,
£68 / 8 = £8.50
Therefore, the cost of one pair of earing will be £8.59.

Solve the system of equations using elimination:
-3х — бу =-6 and
-4х — бу = -4.
Answer:
let's see....
lil info about elimination method:
it has to do with elimination of an entire value and coefficients meaning to get rid of them entirely! so to do that you must have two identical values.
look at -6 in the first equation and the other -6 below it in the second equation.
if you have something like that, then just look for a symbol like - or + that will eliminate them
so we use the - (minus) sign and just subtract the first equation from the second, you would get -x =2.
so x cannot be negative...
so x = -2.
( Incase the numbers aren't the same, you have to do something to make the numbers same but if you have it like that up⬆️ then just use the symbol that would eliminate those same numbers to give you x immediately)

Answer:
Option A, y = -1/3x + 2
Step-by-step explanation:
Step 1: Determine the equation
Looking at the graph we can see that the line will intersect the y-axis at around 2 units which eliminates options B and D. Now, looking at the slope of the graph we see that it's going in a downward trend which means that the slope is negative. That eliminates option C which leaves us with the only option of A.
Answer: Option A, y = -1/3x + 2

• There is a rug you want to purchase for your apartment at Wal-Mart. The
length of the rug is (2x-9) and the width of the rug is (x+5). What is the
total area of the rug? Solve the problem using distributive property. Write
the answer as a trinomial.
Answer
12x-9x-45 (put a 2 above the x on the 12)
Step-by-step explanation:
(2x-9)(x+5)
2x(x) = 2x
2x(5) = 10x
-9(x) = -9x
-9(5) = -45
2x^2+10x^2-9x-45
2x^2+10x^2 = 12x^2
12x^2-9x-45
What is the cube root?
Answer:
its 4/5
Step-by-step explanation:
cube of four is 64 and cube of 5 is 125
Answer:
4 / 5
Step-by-step explanation:
∛( 64 / 125 )
= ∛64 / ∛125
64 can be simplified as 4 x 4 x 4.
∛64
= ∛ ( 4 x 4 x 4 )
= 4
125 can be written as 5 x 5 x 5.
∛125
= ∛ ( 5 x 5 x 5 )
= 5
∛ ( 64 / 125 ) = 4 / 5

The Total Interest Combine will be interest from the compounded invesestment and that of the simple interest investement $13,974.54 plus $13,848.00 which is 27 822.54 US$
Compound InterestGiven Data
Principal = $12,000Rate = 2.2%Time = 7 yearsCalculation For Compound Interest:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.2/100
r = 0.022 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 12,000.00(1 + 0.022/1)(1)(7)
A = 12,000.00(1 + 0.022)(7)
A = $13,974.54
Calculation For Simple Interest:
First, converting R percent to r a decimal
r = R/100 = 2.2%/100 = 0.022 per year.
Solving our equation:
A = 12000(1 + (0.022 × 7)) = 13848
A = $13,848.00

ummi and julio each have a bag that contains 2 blue marbles, 2 green marbles and 2 purple marbles. Ummi selects a marble from her bad, replaces it, and then selects another. julio selects a marble from her bag, replaces, it and then selects another. who has a greater probability of selecting 2 marbles of the same color from the bag? explain.
Answer:
None.
Step-by-step explanation:
Let blue, green and purple be B, G, and P respectively.
Sample Space = 2+2+2 = 6
p(B) = p(G) = p(P) = 2/6 = 1/3
Probability that the two marbles Ummi selected are of the same color (note that the marbles were replaced after selection)
B = (1/3)•(1/3)
+
G = (1/3)•(1/3)
+
P = (1/3)•(1/3)
= 3•(1/9) = 1/3
.
The same thing goes for Julio.
They have the same chance/probability of picking two marbles of the same color.
