Step-by-step explanation:
Given
Six apples and one pear cost [tex]\$1.07[/tex]
Also, three apples and six pears costs [tex]\$1.47[/tex]
Suppose [tex]x[/tex] and [tex]y[/tex] be the price of apple and pear. So, we can write the cost as
[tex]\Rightarrow 6x+y=1.07\quad \ldots(i)\\\Rightarrow 3x+6y=1.47\quad \ldots(ii)\\\text{solve (i) and (ii) we get}[/tex]
[tex]x=0.15,\ y=0.17[/tex]
The cost of an apple is [tex]\$0.15[/tex]

prove that 5^(2n - 1) is divisible by 8
Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.
The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.
On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.
Let's consider a few concrete examples:
If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.
Answer: y = 4x-23
Step-by-step explanation: I'm assuming the question asks: "A line passes through the point (4, - 7) and has a slope of 4." I had difficulty understanding the format of the question. Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We can start with y = 4x + b, since we are given the slope. We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.
y = 4x + b
-7 = 4(4) + b
-7 = 16 + b
b = - 23
The equation is y = 4x-23

What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?
Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

Answer: I think it's 32.8
Step-by-step explanation:
solve the pattern:
15, 17, 32, 49, 81 __ __ ← those are the blank spaces.
Answer:
130 and 211
Step-by-step explanation:
15+17= 32
17+32=49
32+49=81
49+81=130
81+130=211
Answer:
130 and 211
Step-by-step explanation:
15,17,32,49,81 _ _
15+2=17+15=32+17=49+32=81
that mean 81+ 49=130
and 81+130= 211
Hence, the answer is 130 and 211.

Mr. Flores opened an account with a deposit of $5,000.
• The account earned annual simple interest.
• He did not make any additional deposits or withdrawals.
• At the end of 4 years, the balance of the account was $6,500.
What is the annual interest rate on this account?
A. 5.8%
B. 7.5%
C. 3.3%
D. 1.9%
Answer:
B. 7.5%
Step-by-step explanation:
First, we need the Simple Interest (S.I)
Total = Principal + Simple Interest
T = P + S.I
6500 = 5000 + S.I
[make S.I the subject of the formula]
S.I = 6500 - 5000
S.I = 1500
Simple Interest = (Principal × Rate × Time) / 100
S.I = (P × R × T) / 100
1500 = (5000 × R × 4) / 100
1500 = 20000R / 100
1500 = 200R
[divide both sides of the equation by 200]
1500 / 200 = 200R / 200
R = 1500 / 200
R = 7.5
The annual interest rate is 7.5%

How to find perimeter with equations
I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much
Step-by-step explanation:
In blue colour square
Perimeter= 4 × side
= 4 (3x +7)
=12x +28 unit
In green colour square
Perimeter= 4 × side
= 4 ( 5x+1)
= 20x +4 unit
Answer:
12x + 28 = p
20x + 4 = p
Step-by-step explanation:
Assuming that both shapes are square, the perimeter of a square is the equation:
4 * x = p
Where x is the length of one side. Plug the variables in for the first square:
4 * (3x + 7) = p
Expand the brackets:
4 * 3x = 12x
4 * 7 = 28
12x + 28 = p
For the second square, plug the variables in again:
4 * (5x + 1) = p
Expand the brackets:
4 * 5x = 20x
4 * 1 = 4
20x + 4 = p
Hope this helps!

In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total of $5.88.
1. Write an equation to determine the original price per pound (p)
2. Find the original price per pound.
Answer:
$1.21Step-by-step explanation:
Original price = pNew price = p + 0.75Equation:
3(p + 0.75) = 5.88p + 0.75 = 5.88/3p + 0.75 = 1.96p = 1.96 - 0.75p = 1.2130% of the swimming team are girls. If there are 18 girls. How many are in the team
altogether?
Answer:
60 people are in the team altogether
Answer:
60
Step-by-step explanation:
to find the percentage of girls on the swim team, you would multiply a number by 30 percent. to find the number in all, you would divide 18 by 30 percent
18/0.3 = 60
there are sixty people on the swimming team
