Answer:
x=2.5 For both equations to be equal.
Step-by-step explanation:
45+20x=30+26x
Subtract 45 from each sides.
20x=-15+26x
Subtract 26x
-6x=-15
x=2.5
Check:
45+20(2.5)=30+26(2.5)
45+50=30+65
95=95 Correct!
Make x the subject of the formula
p+x=t
Answer:
x=t-p
Step-by-step explanation:
just move p to the other side and since it crosses the equals sign so you have to change it from positive to negative
Answer:
x=t-p
Step-by-step explanation:
To make x the subject of the formula, you’d have to take p to the other side. And when (+p) crosses over to the other side, it changes to (-p) because of the equality sign.

Find the vertex following equation: x2 + 10x = 21
A: (5, -46)
B: (-5, 54)
C: (-5, -46)
D: (5, 54)
Calculate the slope of the line on the graph using the
formula:
72-V1
m
X2 - X
The slope of the line is
_____m/s.
Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
[tex]m=\dfrac{4-0}{1-0}[/tex]
[tex]m=\dfrac{4}{1}[/tex]
[tex]m=4[/tex]
Therefore, the slope of the line is 4 m/s.

The table shows the cost of a sandwich and a drink at a local cafeteria. how much more does a sandwich cost than a drink
Answer:
$2.02
Step-by-step explanation:
1.50/2 = 0.75
0.75 - 0.49 = 0.26
Sandwich = 2(0.75)+1.5 = 3
Drink = (0.49) + 0.49 = 0.98
3 - 0.98 = 2.02
Suppose you are driving. You notice that after driving for 4 hours, you are 135 miles from Seattle. You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. What is your rate? How far do you drive every 9 hours? How far from Seattle are you after driving for 17 hours?
Answer:
1,423
Step-by-step explanation:
Your average rate is 36.7 miles per hour over nine hours
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
In the first 4 hours, you've averaged 33.75 miles per hour, but this is apparently not sustainable, since at 9 hours you've only averaged 36.7 miles/hour.
You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. you've averaged 31.8 miles per hour
So the answer is that your average rate is 36.7 miles per hour over nine hours, although you did manage a faster burst of 50 mph for four hours once.

The perimeter of a certain hexagon is 14.7 centimeters. Five of the sides have the same
length of n centimeters, while the one side has a length of 1.9 centimeters, as shown
below.
Answer:
The value of n is n = 2.56 cm
Option D is correct option.
Step-by-step explanation:
Perimeter of hexagon = 14.7 cm
Five sides have length = n cm
One side has length = 1.9 cm
We need to find value of n
The formula used to find Perimeter of hexagon is : [tex]Perimeter = Sum\;of\:all\:sides[/tex]
We can write:
[tex]Perimeter = Sum\;of\:all\:sides\\14.7=5n+1.9\\[/tex]
Because 5 sides have length = n so, 5n and one side has length = 1.9
Now, solving to find n
[tex]14.7-1.9=5n\\5n=12.8\\n=\frac{12.8}{5}\\n=2.56[/tex]
So, The value of n is n = 2.56 cm
Option D is correct option.
how do i do
x^2 - 7x - 34 = 10
^ = power to
can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4

Jeffrey typed 110 words in 2 3 /4 minutes. At this rate, how many words can he type in 4 1/4 minutes?
Answer:
First, you have to find out the words per second.
2 and 3/5 min = 165 sec
165 sec divided by 110 words = 0.6 words a second
4 and 1/4 min = 255 sec
0.6 x 255 = 153 words in 4 and 1/4 min
Step-by-step explanation:
i hope this helps! Have a nice day!

Find the sum of
(9c+8)+(5x-2)+(3y+7)
Answer:
9c + 5x + 3y + 13
Step-by-step explanation:
you can't combine any of the numbers wwith variables because the variables aren't the same but you can combine the other numbers (8, -2, 7)
8 - 2 = 6
6 + 7 = 13
put the equation back together but instead replace the 8, -2, and 7 with 13 giving you
9c + 5x + 3y +13
3. Andrea is buying snacks at the basketball game. The snacks are $2.25 apiece. She wants to buy 4
snacks. Would the ordered pair (4,9.25) be a solution to this problem? Explain why or why not.
If this is not a solution, provide the correct solution for an x-value of 4.
a) Yes
b) No, the ordered pair (9,4) is a solution to this problem.
c) No, the ordered pair (4, 1.77) is a solution to this problem
d) No, the Ordered pair (4,9) is a solution to this problem.
Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!

the table shows ordered pairs for a polynomial function, f. What is the degree of f?
Answer:
5th degree
Step-by-step explanation:
To solve this problem/table, you have to find the differences in the f(x) side of the table until the differences between the numbers are the same, and then you have your degree. Look at the image attached for more sense
if a triangle has a area of 42 cm^2 and a base of 8 cm, what is the height?
show work plsssss
Answer:
The height would be 10.5 cm
Answer:
hb=10.5cm
Step-by-step explanation:
Area of triangle = 1/2(height x base)
The problem states that base is 8 cm greater than the height; therefore, base-8 = height.
A = 1/2(b*h)
42 = 1/2(b*[b-8])
84=(b^2-8b)
rearrange to
b^2 - 8b -84
factor to
(b+8)(b-14)
Therefore, b = -8 cm which makes no sense and
b = +14 cm
and height = 14-8 = 6
Check:
1/2(b*h) = area
1/2(14*6) = 1/2(84)=42

I believe the ¨Five less than twice a number" is
[tex]2x-5[/tex]
¨Five times the sum of two numbers¨
[tex]5(x+y)[/tex]
¨The difference of 5 and a number squared¨
[tex](5-x)^{2}[/tex]
Answer:
First Box is: 5 - 2x
Second Box is: 5(x + y)
Third Box is: (5 - x)²
Step-by-step explanation:
The First one said "Five less than twice a number"
It said Five less than, meaning 5 (subtract)Twice mean 2 and a number means a VARIABLE. Answer: 5 - 2xThe second one said "Five times the sum of two numbers"
Five times means 5 (multiplication)Sum means adding and two numbers means two variables.Answer: 5(x + y)The thrird one said "The difference of 5 and a number, squared"
The difference means subtracting of 5a number means a variablesquared, means an exponent of 2Answer: (5 - x)²All of these answers seems to fit the descriptions.

Answer:
None, there are no degrees/exponents
Step-by-step explanation:
Hope this is helpful :)
Answer:
has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term
