Uses a distributive property to rewrite the expression as a multiple of a sum of two numbers with no common factor 27+9
Given:
The expression is
[tex]27+9[/tex]
To find:
The expression as a multiple of a sum of two numbers with no common factor.
Solution:
We have,
[tex]27+9[/tex]
It can be written as
[tex]=3\times 9+9[/tex]
Using distributive property taking out the common factors.
[tex]=(3+1)9[/tex] [tex][\because a(b+c)=ab+ac][/tex]
Therefore, the required expression is [tex](3+1)9[/tex].

The Problem
which coordinate is a solution to the equation: 7x + 4y = 9?
a (4, -2)
b. (-33)
c. (3-3)
d. (-4,2)
Answer:
C. (3,-3)
Step-by-step explanation:
7 ( 4) + 4 (-2) = 9 false
7 ( -3) + 4 (3) = 9 false
7 ( 3) + 4 ( -3) = 9 true
7 ( -4) + 4 ( 2) = 9 false

Solving inequality
Answer:
x _> 9 I dont have the symbol on my phone so I just put the greater than sign there
Step-by-step explanation:
1. Subtract 3 from both sides
5x > 48 - 3
2. simplofy 48 - 3 to 45
5x > 45
3. Divide both sides by 5
x > 45/5
4. Then simplify 45/5 to 9 which gives us the answer
And again I dont have the sign thats why I used the greater than sign
Mary draws the number line below to represent the solution set of the inequality 50 – 8t < 90. What mistake did Mary make? Use the drop-down menus to explain your answer.
Picture relating to question is attached below
Answer:
t > - 5
Line is in the wrong side
Step-by-step explanation:
Given the inequality :
50 – 8t < 90
-8t < 90 - 50
-8t < 40
-8t / - 8 < (40/ - 8)
t > - 5 (sign changes)
During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right

Someone please help me with this question I'm struggling
[tex]g(x) = - 2x + 1 \\ 5 = - 2x + 1[/tex]
Solve for the x-term.
[tex]2x = - 5 + 1 \\ 2x = - 4 \\ x = \frac{ - 4}{2} \\ x = \frac{ \cancel{ - 4} \: \: \: - 2}{ \cancel{2} \: \: \: 1} \Longrightarrow \: \frac{ - 2}{1} \\ x = - 2[/tex]
Answer Check
Substitute x = -2 in the equation.
[tex]5 = - 2( - 2) + 1 \\ 5 = 4 + 1 \\ 5 = 5[/tex]
The equation is true. Therefore x = -2 is the answer.
Answerx = -2

7.4
7.9
8.4
10.2
10.6
11.2

Find the middle number:
Since there are 12 numbers, you will have 2 middle numbers which will be the 6th and 7th number: 8.4 and 10.2
Add them together:
8.4 + 10.2 = 18.6
18.6/2 = 9.3

Answer:
H(35)=50-75/5
Step-by-step explanation:
75/5=15
50-15=35
Answer:
h(35)=43
Step-by-step explanation:
You just need to replace the t with 35. So you get the equation of 50-35/5. This is simplified to be 50-7 which is 43. So your final answer is 43.

A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?
a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.
d. No, these horses must be genetically prone to having female offspring
Answer:
A. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
Answer:
(A) No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.

Line n: y =
Line p: x =
If you helped, thank you so much, you are an amazing person <3
Line P: x = -4
Line n: y = x -1

The equation of the lines are,
Line ℓ: y = 4
Line m: y = -2x + 4
Line n: y = x - 1
Line p: x = -4
What is a line?A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
From the map,
Locate at least 1 point in every line to define the equation of line,
Consider line l,
Now, on the y-axis line l passes through (0, 4),
Standard equation of the line,
y = mx + c,
Since the slope of the line l is zero and the y-intercept is 4, so the equation is,
y = 0(x) + 4
y = 4
Similarly, the equation of the other line is givens,
Line m
y = -2 + 4 (slope is -2 and y-intercept is +4)
Line n,
y = x - 1 (slope is 1 and y-intercept is -1)
Line p
x = -4 (slope is 1/0 and y-intercept is 0)
Thus, the equation of the line is shown above.

A skin care company had 1,500 people try a new acne cream. Nine people had a mild reaction the formula is then improved and those 1,500 people try the new cream only 4
Answer:
The percent decrease in number of allergic reactions is 55%
Step-by-step explanation:
Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?
Percent of allergic people= Allergic people/ Total people * 100
= 9/1500* 100
= 0.6 %
IT means that out of 1000 people only 6 persons are allergic to the cream.
New Percent of allergic people= Allergic people/ Total people * 100
= 4/1500* 100
= 0.267 %
It means that out of 1000 people only 2.67 persons are allergic to the new improved cream.
Difference between Percentage = Old Percentage- New Percentage
= 0.6 %- 0.267%
=0.333%
Decrease= 0.333% = 0.333/100
In every thousand people 3.33 people are free of allergic reactions from those 6 allergic people.
Percentage Decrease= Decrease/ Total * 100
= 0.333/ 0.6 *100
= 0.55*100
= 55 %
The percent decrease in number of allergic reactions is 55%
