Answer:
Xavier has 5 dollars
Step-by-step explanation:
2x represents how much money Alex had, the -3 is how much he spent, and the 7 is how much he has now
[tex]2x-3=7[/tex]
Add 3 to both sides
[tex]2x=10[/tex]
divide both sides by 2
[tex]x=5[/tex]
Checking my work:
[tex]2*5-3=7\\10-3=7\\7=7[/tex]

Solve the equation -2x + 9 - 3x= -5x + 3
Answer:
There are no solutions
Step-by-step explanation:
Answer:
no real solutions
Step-by-step explanation:
-2x + 9 - 3x = -5x + 3
First, combine like terms on each side.
-2x - 3x + 9 = -5x + 3
-5x + 9 = -5x + 3
Continue to combine the like terms from both sides.
0 = -6
The above expression is not true, therefore, there are no real solutions.
FREE BRAINLIEST! if you can answer this correctly ill give you brainliest and answer some of the questions you have posted :) thank you very much!!! (40pts)
Answer:
225 cm^3
Step-by-step explanation:
Using the slope formula, find the slope of the line through the points (0,0) and (4,8) . Use pencil and paper. Explain how you can use mental math to find the slope of the line
Answer:
Look below! I hope this helps, and mark as brainliest please!
Step-by-step explanation:
The formula for slope is (y2-y1) divided by (x2-x1). So in this case, we have (8-0) divided by (4-0) so we get 8 over 4 and that is 2. So the slope is 2.

Jaimie is practicing for the long jump. Each week she makes 10 jumps and after each jump she records the distance, in meters, she reaches with each jump. Her results for this week are represented in the table below. Jump 1 2 3 4 5 6 7 8 9 10 Distance (m) 5.1 5.3 5.4 5.2 5.5 5.4 5.2 5.3 5.5 3.5 Jaimie then reviews her results and determines the mean and standard deviation so that she can compare her results from this week to her results from the previous week. Jaimie felt the 10th jump was not reflective of her ability because she stumbled before making the jump and decided to remove the 10th jump from her data set. Determine whether each statement describes the change that will occur to the mean and standard deviation from this week's results when Jaimie removes the 10th jump from her data set. Select Yes or No for each statement. Yes No Removing the 10th jump from her data set will cause her average jump distance to increase. Removing the 10th jump from her data set will cause her average jump distance to decrease. The standard deviation will increase because the jump distances will be more spread out. The standard deviation will decrease because the jump distances will be more clustered together.
Answer:
mean=(5.1 +5.3+ 5.4 +5.2+ 5.5 +5.4+ 5.2 +5.3 +5.5+ 3.5)/10=51.4/10=5.14
Neelam's daily income is ₹ 800. Her daily savings amount is ₹100. What is the ratio of her SAVINGS to her EXPENDITURE? a. 1 : 2 b. 1 : 7 c. 1 : 6 d. 1 : 5
Given:
Neelam's daily income is ₹800.
Her daily savings amount is ₹100.
To find:
The ratio of her SAVINGS to her EXPENDITURE.
Solution:
We have,
Income = ₹800
Saving = ₹100
Expenditure = Income - Saving
= ₹800 - ₹100
= ₹700
We need to find the ratio of her SAVINGS to her EXPENDITURE.
[tex]Ratio=\dfrac{Savings}{Expenditure}[/tex]
[tex]Ratio=\dfrac{100}{700}[/tex]
[tex]Ratio=\dfrac{1}{7}[/tex]
[tex]Ratio=1:7[/tex]
Therefore, the correct option is b.
If 8x - 5y = -8 is a true equation, what would be the value of -5y + 8x?
Answer:
Answer:
The value of -5y + 8x would be 8.
Step-by-step explanation:
The new equation is just the original equation but multiplied by -1 to make the symbols different. By following this rule, -8 would turn into just 8.

what is the amount of pieces in each color
Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78

Answer:
(3, 3)
Step-by-step explanation:
I guess you're looking for a point that satisfies 2 functions (red and blue). That point is an intersection of these two functions, hence (3,3)
Answer:
[tex]\boxed{\boxed{(x,y)=(3,3)}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:system of linear equationgraphing system of linear equationtips and formulas:when we have two linear equation to find the value of x and y is called the system of linear equationwhen we have graph, the solutions of system of linear equation are the coordinates of two lines cross togetherlet's solve:since you can see at "tips and formulas" what linear equation is and what the solutions are when you have graph
if you see the graph attentively, you can see that the blue line and the red line cross together at (3,3) coordinates
therefore
the solution of the system of linear equation is
(x,y)=(3,3)
if f(x)= 3x-4, find f(-2) - f(3)
Answer:
-15
Step-by-step explanation:
f(-2) = 3(-2) - 4 = -6 - 4 = -10
f(3) = 3(3) - 4 = 9 - 4 = 5
f(-2) - f(3) = -10 - 5 = -15
2a+b=5 and 6y+4y=48 show that 20a+10b has a greater value than 3x+2y
Answer:
Step-by-step explanation:
There is an error in the question. 6x+4y = 48
Multiply first equation by 10:
20x+10y = 50
Divide second equation by 2:
3x+2y = 24
50>24, so 20x+10y > 3x+2y
