Given:
p: 2x -5=5
q: 4x-6=14
P 9
Write the contrapositive in if-then form.
O If 2x–5=5, then 4x - 6=14.
If 4x -6=14, then 2x-5=5.
If 2x – 5≠5, then 4x - 6≠14.
If 4x - 6≠4, then 2x–5≠5.
Answers
Answer:
we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
Step-by-step explanation:
We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".
In other words, it is symbolically represented as:
' ~q ~p is the contrapositive of p q '
For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."
Given
p: 2x -5=5
q: 4x-6=14
As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p
Thus, we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
The difference between two numbers is 10 and
their sum is four times the smaller number.
Find the two numbers.
Answers
Answer:
x = 10
y = 5
Step-by-step explanation:
Let the two numbers be x and y
Difference between the two is 10
x-y = 10
Sum;
x+ y is four times the smallest number
Let the smaller number be y
x+ y = 4y
Subtracting equation ii from i
-2y = 10 -4y
4y-2y = 10
2y = 10
y = 10/2
y = 5
Recall;
x-y = 10
x = 10 + y
x = 10 + 5 = 15

what property is 8x9x3=3x9x8
Answers
Property which represents the given method (8x9)x3= (3x9) x8 is associative property over multiplication.
As given in the question :
Given method :
(8x9)x3= (3x9) x8
On left hand side (8x9)x3
First we multiply 8×9 =72 and then multiply it to 3
72 ×3=216
On right hand side (3× 9)×8
First we multiply (3×9) =27 then multiply it to 8
27×8=216
Left hand side = right hand side
It represents associative property over multiplication.
Therefore, property which represents the given method (8x9)x3= (3x9) x8 is associative property over multiplication.

A man is carrying a pole of length 5m the pole is measured to the nearest centimetre
Answers
The pole measures 500 centimeters.
We are required to perform unit conversion to find the answer. Conversion of unit requires the relating link between two units. While relating the two units, usually greater unit holds singular or unit value, which is 1. The smaller unit holds value greater than 1, but at equivalent level with first unit. So, as per the known fact, 1 meter is equal to 100 centimeters. Using this formula to find measurement of 5 meters in centimeters.
1 meter = 100 centimeters
5 meters = 100 × 5
Performing multiplication to find the measurement of pole in centimeters
5 meters = 500 centimeters
Therefore, the measurement of pole is 500 centimeters.

Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2 pounds of bananas for a total of $5.25. This system of equations represents the situation, where x is the cost per pound of apples, and y is the cost per pound of bananas.
5x + 3y = 8.5
3x + 2y = 5.25

Answers
The mean repair cost for the stereos is (63.04, 102.86) with an 80% confidence interval.
What is the critical factor?The critical factor for a 90% confidence interval for the true mean repair cost for stereos is given by;
Critical factor = (x-μ)/(s/√n)
where, x = sample mean repair cost
s = standard deviation of a sample
n = sample of stereos
μ = critical value
We have been given that a student records the repair cost for 17 randomly selected washers. a sample mean of $82.95 and a standard deviation of $14.89 are subsequently computed.
Since we don't know the population standard deviation, we used t statistics to create the 80% confidence interval in this case.
So, the 80% confidence interval for the true mean repair cost, μ is ;
⇒ P(-1.337< t₅ < 1.337) = 0.80
{As the critical value of t at 5 degrees of freedom are -1.337& 1.337 with P = 5%}
⇒ P(-1.337< (x-μ)/(s/√n) < 1.337) = 0.80
⇒ P(-1.337×(s/√n) < (x-μ) < 1.337×(s/√n)) = 0.80
⇒ P(x - 1.337×(s/√n) < μ < x + 1.337×(s/√n)) = 0.80
80% confidence interval for
⇒ μ = (x - 1.337×(s/√n) , x + 1.337×(s/√n))
Here, x = $82.95 , s = $14.89 , and n = 17
⇒ μ = (82.95 - 1.337×(14.89 /√17) , 82.95 + 1.337×(14.89 /√17))
⇒ μ = (63.04, 102.86)
Hence, the mean repair cost for the stereos is (63.04, 102.86) with a 80% confidence interval.

the model represents x2 – 9x 14. an algebra tile configuration showing only the product spot. 24 tiles are in the product spot: 1 is labeled x squared, 9 are labeled negative x, and 14 are labeled .
Answers
The factors of the model x^2-9x+14 is (x-2) and (x-7)
The model is x^2-9x+14
Factoring the expression, we get
x^2-7x-2x+14=0
x(x-7)-2(x-7)=0
(x-2)(x-7)=0
The factors of the given model is (x-2)(x-7)
To check if it is a factor or not substitute x=2
2^2-9(2)+14=4-18+14=4-4=0
So x-2 is a factor of the model
7^2-9(7)+14=49-63+14=49-49=0
So x-7 is also a factor of the given model

Step-by-step explanation: The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.
Use proportion. The total length of side FV is 16.
6:16 = x:15 . or 6/16=x/15
cross multiply 15 × 6 = 90, then divide 90/16
90/16 = x
