Answer:
Step-by-step explanation:
c + a = 342 ..................... (1)
5c + 12a = 2550 ........... (2)
- 5 × (1) + (2)
7a = 840
a = 120
c = 342 - 120 = 222

what is the solution for this system of equations?
y= -1/4x + 6
y= x+1
9514 1404 393
Answer:
(x, y) = (4, 5)
Step-by-step explanation:
Equating the expressions for y gives ...
-1/4x +6 = x +1
5 = 5/4x . . . . . . . add 1/4x-1
4 = x . . . . . . . . . . multiply by 4/5
y = x +1 = 4 +1
y = 5
The solution is (x, y) = (4, 5).
7-3x = -x+1
Simplify this equation
Answer:
x=11

Triangle ABC, shown in the diagram below, is an isosceles triangle
If the measure of <ABC is 42.5°, what is the measure of <ABC?
Answer:
A. 42.5
Step-by-step explanation:
The triangle shown is an isosceles triangle. An isosceles triangle haas two of its sides and base angles equal. Hence;
<ACB = <ABC (Base angles are equal)
Given
<ACB = 42.5°
Required
<ABC
According to the law above which says <ACB = <ABC , hence <ABC is also equal to 42.5°

write an equation in slope intercept form of the line with the given characteristics:
through: (-3,1), slope = 2
please help this is due in 10 minutes!!
Answer:
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
Step-by-step explanation:
The slope-intercept form of an equation is given by:
[tex]y = mx+b[/tex]
here m is the slope of the line and b is the y-intercept
Given
[tex]m = 2[/tex]
Putting m=2 in the general form
[tex]y = 2x+b[/tex]
In order to find the y-intercept, the given point (-3,1) will be substituted in the equation
So
[tex]1 = 2(-3)+b\\1 = -6+b\\b = 1+6\\b = 7[/tex]
Putting the value of b
[tex]y = 2x+7[/tex]
Hence,
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7

Use the Distributive Property to solve the equation. 4x - 2(x - 3) = -4 + 5x - 5
Answer:
x=5
Step-by-step explanation:
First, open up the parentheses to get 4x-2x+6=-4+5x-5. Now, move all numbers without variables to the right and those with variables to the left to get 4x-2x-5x=-4-5-6. Simplify both sides to have -3x=-15. Now divide both sides by -3 to get x=5
Find an equation of the line with the given y-intercept and slope m.

In the 2002 - 2003 NBA regular season, the Sacramento Kings
won 13 more than twice as many games as they lost, The Kings
played 82 games. How many wins and losses did the team
mave?
Answer: Number of games lost = 23 and Number of games won = 59.
Step-by-step explanation:
Let x = Number of games lost, y = Number of games won.
y = 13 + 2x (i)
x+ y = 82 (ii)
Substitute value of y from (i) in (ii) , we get
x+ 13 + 2x = 82
⇒ 3x= 82-13
⇒ 3x = 69
⇒ x= 23 [Divide both sides by 3]
Put value of x in (i), y= 13+2(23) = 13+46=59
Hence, Number of games lost = 23 and Number of games won = 59.
the tables represent two linear functions in a system. what is the solution to this system?
Answer: The solution is the point (-14, -54)
Step-by-step explanation:
When we have a system of linear equations like:
y = a*x + b
y = c*x + d
The solution of this system is the point (x, y) that is a solution for both equations, if we graph the lines, this point would be the point where the lines intersect.
To start with this, we need to find the equations of the lines, we will use the following:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Now, for the first table, we can use the points: (-3, -10) and (0, 2)
The slope of this line is:
a = (2 - (-10))/(0 - (-3)) = 12/3 = 4
then we have:
y = 4*x + b
To find the value of b, we can just replace one of the points in the equation, for example, we can use the point (0, 2), this means that we need to replace x by 0, and y by 2.
2 = 4*0 + b
2 = b
Then the equation for the first table is y = 4*x + 2
For the second table, we can use the points (0, -12) and (3, - 3)
Then the slope is:
a = (-3 - (-12))/(3 - 0) = 9/3 = 3
Then we have:
y = 3*x + c
And to find the value of c, we can do the same as before, now we use the point (0, -12) then:
-12 = 3*0 + c
-12 = c
Then the equation for this line is:
y = 3*x - 12
The system of linear equations is then:
y = 4*x + 2
y = 3*x - 12
To find the solution of the system, we must have that y = y, then we can write:
4*x + 2 = y = 3*x - 12
4*x + 2 = 3*x - 12
Now we can solve this for x.
4*x - 3*x = -12 - 2
x = -14
x = -14
Now we can replace this in one of the equations to find the value of y.
y = 3*(-14) - 12 = -54
Then the solution is the point (-14, -54)
Which of the following points is a solution of 3x-y= -2
x = [tex]\frac{y}{3}[/tex] - [tex]\frac{2}{3}[/tex]

Last year, Josh had $20,000 to invest. He invested some of it in an account that paid 7% simple interest per year, and he invested the rest in an account that paid 9% simple interest per year. After one year, he received a total of $1560 in interest. How much did he invest in each account?
Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.

Step-by-step explanation:
i just divided 200 by 3.17
Answer:
63
Step-by-step explanation:
$3.17/share
$200 / $3.17 = 63.09
Let's round to the nearest whole number. 0.9 is 0.9 units away from 63 and 64 is 0.91 units away from 63. Which number should we round to? Since it says nearest, we round to 63.
B or 63 is the answer to the problem.
