How do you solve -4(x + 5) - 9 = -45
Answer:
x=4
Step-by-step explanation:
Add 99 to both sides.
-4(x+5)=-45+9−4(x+5)=−45+9
Simplify -45+9−45+9 to -36−36.
-4(x+5)=-36−4(x+5)=−36
Divide both sides by -4−4.
x+5=\frac{-36}{-4}x+5=
−4
−36
Two negatives make a positive.
x+5=\frac{36}{4}x+5=
4
36
Simplify \frac{36}{4}
4
36
to 99.
x+5=9x+5=9
Subtract 55 from both sides.
x=9-5x=9−5
Simplify 9-59−5 to 44.
x=4

- -4 (x + 5) - 9 = -45
Add 9 to both sides! This makes:
-4 (x + 5) - 9 + 9 = -45 + 9
Simplify!
-4(x + 5) = -36
Divide both sides by -4! This makes:
-4(x + 5) over -4 = -36/-4
Simplify!
x + 5 = 9
Subtract 5 from both sides! This makes:
x + 5 - 5 = 9 - 5
Simplify
x = 4
If x = 4..
-4 (4 + 5) - 9 = -45
-4(4 + 5) - 9
4(4 + 5) = 36
= -36 -9
Subtract the numbers: -36 -9 = -45!
= -45

In a collection of coins, the number of quarters is one-third the number of pennies. The number of quarters is Q. The number of pennies is P. What is the correct formula relating Q to P
Answer:
Q = P/3
Step-by-step explanation:
Let the number of quarters be Q
Let the number of pennies be P
If the number of quarters is one-third the number of pennies, this can be expressed as;
Number of quarter = 1/3 of pennies
Q = 1/3 of P
Of means multiplication
The expression becomes;
Q = 1/3 × P
Q = P/3
Hence the formula relating Q to P is
Q = P/3

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?
Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool

For an upcoming school field trip, there must be one adult supervisor for every five children.
If the bus seats 40 people, how many children can go on the trip?
Answer: 32 Childrens maximum I think
Step-by-step explanation: I believe it is 32 because there will be 8 adults for every 32 children (ratio 1 adult:5 children) then convert the ratio to ?adult: availaible seats (40) so multiply by 8 since 5×8 equals 40 and 8×1 equals 8 but the adults have their spots too so 40-8=32

Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.
Based on the diagram, which expresses all possible lengths of segment AB?
AB = 25
27 81
Based on the diagram, the expression which shows the possible length of segment AB shows that 27 < AB < 81
A triangle that does not have equal sides and angles is known as a scalene triangle.
From the figure attached below, let's have a triangle ABC by using the parameter in the instructions given.
where;
side |AC| = 27side |CB| = 54side |AB| = ???We can use the Pythagoras rule to determine the side |AB|.
Pythagoras rule states that the sum of the hypotenuse squared is equal to both the sum of the opposite squared and adjacent squared.
hyp² = opp² + adj²
AC² = AB² + CB²
54² = AB² + 27²
[tex]\mathbf{AB^2 = 54^2 - 27^2}[/tex]
[tex]\mathbf{AB^2 = 2187}[/tex]
[tex]\mathbf{AB =\sqrt{ 2187}}[/tex]
AB = 47
Therefore, we can conclude that the expression which shows the possible length of segment AB shows that 27 < AB < 81.
