Answer:
Step-by-step explanation:
Given
cost of 2.5 pounds of cheese is $5.60.
To get the cost of one pound, we will use the equality postulate:
2.5 pounds = $5.60
1 pound = $x
cross multiply;
2.5x = 5.60
x = 5.60/2.5
x = $2.24
Hence one pound of cheese will cost $2.24
b) If Mrs. Peterson bought 4.75 pounds of cheese, to get the amount she paid, we will say:
1 pound = $2.24
4.75pounds = y
cross multiply
1*y = 2.24 * 4.75
y = $10.64
Hence the cost of 4.75pounds is $10.64
c) To find the cost of 5 pounds, we can use the fact that 2.5 pounds of cheese cost $5.60;
hence 2.5 pounds = $5.60
5 pounds z
cross multiply
2.5z = 5*5.60
z = 5*5.60/2.5
z = 2*5.60
z = $11.2
Hence the cost of 5 pounds of cheese is $11.2
Johathan purchases 10 traveler's checks in denominations of $20, $50, and $100, totaling $370.He has twice as many $20 checks as $50 checks. How many of each denomination of traveler's checks does he have?
Answer:
Six 20$ bills, Three 50$ bills, One $100 bill
Step-by-step explanation:
6x20=120
3x50=150
1x100=100
120+150+100=370
and there are twice as many 20$ checks than 50$ checks

Question in picture please solve
Answer:
n=8
Step-by-step explanation:
-6=n/2-10 -- switch sides
n/2-10= -6 -- add 10 to both sides
n/2-10+10= -6+10 -- simplify
n/2=4 -- multiply both sides by 2
2n/2=4 times 2 -- simplify
n=8 -- answer
Determine the average rate of change over left curly bracket negative 4 less or equal than x less or equal than 4 bold right curly bracket. Do NOT simplify.
Answer:
{-4≤ x≤ 4}
The average rate of change would be 1 for f(x) = x.
Step-by-step explanation:
Suppose we have a range a≤x≤b, then the average rate of change can be calculated by =f(b) - f(a)/b-a
The given range lies from -4 to 4 as {-4≤ x≤ 4}
The range of this is from -4 to 4.It includes all the numbers ranging from -4 to 4.
The average rate of change of the function is calculated by
= f(4) - f(-4)/4-(-4)
Suppose f(x)= x then f(4)= 4 and f(-4)= -4
Then
4- (-4)/ 4- (-4)
= 8/8= 1
So the average rate of change would be 1.

Multiply.
(25)(−54)
Enter your answer as a fraction, in the simplest form, in the box.
Answer:
-1350 is the answer.
Step-by-step explanation:
The value of multiplication of 25 and -54 will be -1350/1.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression as;
25 × -54
Now. Solve the expression as;
25 × -54 = - 1350
It can be written as a fraction;
- 1350 = -13500/10
After simplified we get;
- 1350 = -13500/10
= -2700/2
= -1350/1
Thus, The value of multiplication of 25 and -54 will be -1350/1.

find the value of x and y. if (x+y,1) =(2,2x-y)
Answer:
x=1/3. y=3/2
Step-by-step explanation:
x+y=2. =>equation 1
2x-y = 1. => equation 2
equation 1 + equation 2,
x+y+(2x-y) = 2-1
x+y+2x-y = 1
3x = 1
x=1/3
plug in value of x in equation 1,
1/2 + y = 2
y= 2 - 1/2
y = 3/2

A radio station gave away 192 tickets to a concert. They gave away 5 times as many tickets to listeners as they gave to employees. How many tickets did they give away to employees?
Answer:
Tickets to workers= 32
Step-by-step explanation:
Giving the following information:
Total tickets= 192
They gave away 5 times as many tickets to listeners as they gave to employees.
We will use the rule of 3:
6/6=192
5/6= ? = 192*(5/6) = 160
They gave 160 tickets to listeners.
Tickets to workers= 192 - 160= 32
Prove:
32*5= 160

the perimeter of the given equilateral triangle is 42 cm find s if it's side length is (3s+2) cm
Answer:
14cm
Step-by-step explanation:
Given parameters:
perimeter of the triangle = 42cm
length of side = (3s + 2)cm
Unknown:
Find the length of each side = ?
Solution:
The perimeter of a body is the sum of all its sides.
In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;
(3s + 2) + (3s + 2) + (3s + 2) = 42
9s + 6 = 42
9s = 42 - 6
9s = 36
s = 4;
The length of its sides = 3s + 2
= 3(4) + 2
= 12 + 2
= 14cm

If ∆TIK ≅ ∆TOK and < I = (5x + 8), < K = 92, and < O is 50. What is the measure of < I?
Answer:
<I = 50
Step-by-step explanation:
Sum of angles in ∆TOK is 180
Given
< I = (5x + 8),
< K = 92, and
< O is 50.
<T + <O+<K = 180
<T +92+50 = 180
<T + 142 = 180
<T = 180-142
<T = 38
Also <T+<I+<K = 180
38+5x+8+92 = 180
5x+138 = 180
5x = 42
x = 42/5
x = 8.4
Since <I = 5x+8
<I = 5(8.4)+8
<I = 42 + 8
<I = 50
Answer:
=50
