Answer:
-31p
Step-by-step explanation:
The simplified form of the expression 4p - 5p - 30p is -31p.
The given expression is,
4p-5p-30p
Expressions are simplified when they are rewritten in a concise manner and without any similar phrases. When we combine similar terms in an expression and, if necessary, solve all of the specified brackets, we are only left with unlike terms in the simplified expression that cannot be further reduced.
Combine like terms,
We have three terms with the variable p.
Combining them, we get -p - 30p, which simplifies to -31p.
Mathematically we can write,
(4-5-30)p
= (-1-30)p
= -31p
Therefore, the simplified form of the expression 4p - 5p - 30p is -31p.

A town's population in 2019 was 438,000. The town's current population is 561,000. What is the percent of change?
Answer:
28.1%
Step-by-step explanation:
A town's population in 2019 was 438,000. The town's current population is 561,000. What is the percent of change?
The formula for Percent change =
Final value - Initial value/Initial value × 100
= 561000 - 438000/438000 × 100
= 123000/438000 × 100
= 28.082191781%
Approximately = 28.1%
Therefore, percent change = 28.1%

What is the value of x?
Answer:
x = 12
Step-by-step explanation:
From the similar figures given in the picture,
(Figure A ~ Figure B)
Corresponding sides of the figures will be proportional.
By this property of the similarity,
[tex]\frac{x}{10}= \frac{30}{25}[/tex]
x = [tex]\frac{300}{25}[/tex]
x = 12

Answer:
Hope this helps~
Step-by-step explanation:
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .
Answer:
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2. That's positive.
The line on the graph slopes up. To walk it, you have to climb.

Jackson invested $8,800 in an account paying an interest rate of 7% compounded
daily. Assuming no deposits or withdrawals are made, how much money, to the
nearest dollar, would be in the account after 13 years?
Answer:
$21,860
Step-by-step explanation:
The amount after 3 years will be $ 21,206.6
To understand more, check below explanation.
Compound interest:If the amount P is invested at the rate of r% for n years.
Then amount after n years is computed as;
Given that, Principal = $8,800 , r = 7% and n = 13 years.
[tex]A=P(1+\frac{r}{100} )^{n}\\ \\A=8800(1+\frac{7}{100} )^{13} \\\\A=8,800*(\frac{107}{100} )^{13}\\ \\A=\$ 21206.6[/tex]
Hence, the amount after 13 years will be $ 21,206.6

Answer:

Step-by-step explanation:
Matty's speed = 9 km/hr
We need to convert 9 km/hr to m/s
We know that,
1 km = 1000 m
1 hour = 3600 seconds
[tex]v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s[/tex]
So, Matty jogs with the speed of 2.5 m/s.

Donna rides her bike at a rate of 19/2 miles per hour how many miles can Donna travel in1/3 of an hour
Answer:
3 1/6 miles
Step-by-step explanation:
Rate(Speed )= Distance/Time
From the Question, we are to find the distance.
The formula for Distance = Rate × Time
Rate = 19/2 mile per hour
Time = 1/3 of an hour.
Distance = 19/2 miles per hour × 1/3 hour
= 19/6 miles
= 3 1/6 miles
Donna can travel 3 1/6 miles in 1/3 of an hour
Drawn the graph of y=6-2x on the grid
Answer:
Please check attachment
Step-by-step explanation:
Here, we want to plot the graph of y = 6-2x on the grid
We can rewrite this to look like the general form as;
y = -2x + 6
The y-intercept is 6
This point is (0,6)
For the x-intercept, equate y to 0
0 = -2x + 6
2x = 6
x = 6/2
x = 3
The x-intercept is (3,0)
So we have to join the point (3,0) with (0,6)
Please check the attachment for the plot of this on the grid

Brianna wants to buy a digital camera for a photography class. One store offers the camera for $49 down
and a payment plan of $20 per month. The payment plan for a second store is described by y - 15x + 79,
where y is the total cost in dollars and x is the number of months. Which camera is cheaper when the
camera is paid off in 12 months? Complete the explanation.
Answer:
Step-by-step explanation:
Cost of the camera at one store,
Down payment = $49
Per month payment = $20
Duration of the payment = 12 months
Total payment to be done = down payment + payments to be done in 12 months
= 49 + (20×12)
= 49 + 240
= $289
Cost of the camera at second store,
Equation describing the payment plan,
y = 15x + 79
Here, x = number of months
y = Total amount to be paid
If x = 12 months
y = (15×12) + 79
y = 180 + 79
y = $259
The camera at the second store is cheaper when the camera is paid off in 12 months because the cost at the first store is $289 and the cost at the second store is $259.
