Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
x = 4
Step-by-step explanation:
Original Equation:
3(x + 2) = 2(x + 5)
Use distributive property
3 · x = 3x
3 · 2 = 6
Your equation should look like this now:
3x + 6 = 2(x + 5)
Use distributive property for the other side
2 · x = 2x
2 · 5 = 10
Your equation:
3x + 6 = 2x + 10
Subtract 6 from both sides
3x = 2x + 4
Subtract 2x from both sides
1x = 4
Divide both sides by 1
x = 4

Is the unit rate of change for the linear function shown in the table?
What is the slope of the line through (-1, 4) and (1, -2)
Answer:
Slope = -3
Step-by-step explanation:
The slope is the change in y over the change in x
The slope formula is m=y₂-y₁/x₂-x₁ (y over x)
So, plug in your coordinates (the subscript represents the order in which your points are going to be subtracted in)
So, you would get m=-2-4/1-(-1)
Simplify (first subtract the top, then subtract the bottom)
This would get you to -6/2 (remember your rules: a negative and a negative makes a positive)
-6/2 would get you to -3

The total length of a beach is 13.2 kilometers. If lifeguards are stationed every 0.6 kilometers, including one at the end of the beach, how many lifeguards will there be on the beach?
Answer:
22 including one at the end of the beach
Step-by-step explanation:
Total length of the beach = 13.2 kilometers
If lifeguards are stationed every 0.6 kilometers, INCLUDING one at the end of the beach
Number of lifeguards in the beach = Total length of the beach / distance interval of each lifeguards
= 13.2 kilometers / 0.6 kilometers
= 22
Number of lifeguards in the beach = 22 including one at the end of the beach
Which equation best represents the relationship between x and y in the graph? please guys I need help.
Answer:
its a or y = -3/4x -3
Step-by-step explanation:
slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. the line intercepts at the y at point -3 so the y-intercept is -3 the slope is -3/4 and you just plug them into the slope intercept form
What is the product of -8/9 x -6/7
Answer:
16/21
Step-by-step explanation:
In the first fraction, the negative numerator and negative denominator cancel each other.
In the second fraction, the negative numerator and negative denominator cancel each other.
The equivalent equation is
8/9×6/7=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
8×6/9×7=48/63
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 48 and 63 using
GCF(48,63) = 3
4/8÷43/63÷3=16/21
Therefore:
−8/9× −6/7=16/21

Shryia read a book cover to cover in a single session, at a constant rate. After reading for 1.5, point, 5 hours, she had 402 out of the total 480 pages left to read.
Answer:
y = -52x + 480
Step-by-step explanation:
Let us assume the number of pages left be x
And, the number of hours is x
According to the question
Data given is as follows
Number of hours 1.5 and 5
Total pages 480
Left pages 402
Based on the above information,
The computation is shown below;
Pages read by Shriya in 1.5 hours is
= Total pages in the book - left pages to read
= 480 pages - 402 pages
= 78 pages
And, there is 1.5 hours
So in one hour she read
= 78 pages ÷ 1.5 hours
= 52 pages per hour
So, the equation is
y = -52x + 480

A six-sided die is tossed and a coin is flipped. What is the fractional probability that the die lands on an even number and the coin is heads?
Answer:
the die: 1/2, coin: 1/2
Step-by-step explanation:
There are 6 sides on a die and 6 numbers, 3 are even numbers which means 3/6. simplify it to get 1/2
there are 2 sides on a coin, one is heads. Therefore, the probability is 1/2
The fractional probability that the die lands on an even number and the coin is heads is [tex]\frac{1}{4}[/tex].
What is probability?"Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."
Given, a die is tossed and a coin is flipped.
Therefore, the number of outcomes in case of die is 6 and the number of favorable outcomes is 3.
Hence, in case of the die, probability of getting an even number is P(A) = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex].
Again, the number of outcomes in case of the coin is 2 and the number of favorable outcomes is 1.
Hence, in case of the coin, probability of getting head is P(B) = [tex]\frac{1}{2}[/tex].
Now, the fractional probability that the die lands on an even number and the coin is heads is = P(A) × P(B) = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex].

Rena spent 6 days reading her book completing the same fraction of the book each day if she had a total of 8/9 of her book after 6 days what fraction of the book did she react each day
Answer:
The fraction of the book that Rena read every day is [tex]\frac{4}{27}[/tex]
Step-by-step explanation:
Rena spent 6 days reading her book completing the same fraction of the book every day and you want to know the fraction of the book she read each day. Knowing that Rena had a total of 8/9 of her book read after 6 days, then you simply divide the total amount of the book read during those days by 6, the number of days:
[tex]\frac{8}{9}[/tex]÷6
To divide a fraction by a whole number, you must convert the whole number into a fraction, finding the reciprocal of that fraction, and multiply it by the first fraction. That is, you must find the reciprocal of the number that is after the division symbol; and then you multiply the first number (the one before the division symbol) by the reciprocal of the second number (the one after the division symbol). Remember that to find the reciprocal of a number, you simply have to change the numerator and denominator of the number.
Since 6 can be considered to be a fraction equal to [tex]\frac{6}{1}[/tex], by inverting the number, then you get [tex]\frac{1}{6}[/tex]
Then:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}[/tex]
Now you multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final solution.
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}[/tex]
Finally, simplifying the fraction:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}=\frac{4}{27}[/tex]
So:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{4}{27}[/tex]
The fraction of the book that Rena read every day is [tex]\frac{4}{27}[/tex]
