please solve this problem.
x=number of oranges.
y=number of bananas.
$5
we can suggest this system of equations:
x+y=12
0.5x+0.25y=5
We can solve this system of equations by substitution method.
x=12-y
0.5(12-y)+0.25y=5
6-0.5y+0.25y=5
-0.25y=5-6
-0.25y=-1
y=-1 /- 0.25=4
x=12-y
x=12-4=8

Solve system of equation algebraically
y = 2x - 3
x + y = 18
Answer:
x = 7
y = 11
Step-by-step explanation:
Given the system;
y = 2x - 3
x + y = 18
1. Approach
The easiest way to solve this system of equations is to solve the second equation for the variable (y). Then add the systems, use algebra to solve for the value of (x), then substitute that value back into one of the original equations to solve for the value of (y). Another name for the method in use is the method of elimination, this is when a [erspm manipulates one of the equations in a system of the equation such that when they add the equations, one of the variables eliminatates. Thus, they can solve for the other variable and the backsolve for the value of the unknown variable.
2. Solve one of the equations for a variable
Manipulate the system such that each equation is solved for the same variable,
x + y = 18
Inverse operations,
x + y = 18
-18 -18
x + y - 18 = 0
-y -y
x - 18 = -y
3. Use elimination
Now substitute this back into the original system,
y = 2x - 3
-y = x - 18
Add the systems,
y = 2x - 3
-y = x - 18
_________
0 = 3x - 21
Inverse operations,
0 = 3x - 21
+21 +21
21 = 3x
/3 /3
7 = x
4. Find the value of the unknown variable
Backsovle to find the value of (y),
x + y = 18
Substitute,
7 + y = 18
Inverse operations,
7 + y = 18
-7 -7
y = 11
Answer:
X=3 Y=15
Step-by-step explanation: First you need to use the problem 18/2=x to find the value of x. Now to find the value of y, you need to subtract 3 from 18. Then you solve
15=2(9)-3 15+3=18

PLEASE HELP QUICK I DON'T KNOW HOW TO DO
Answer:
1. 2
2. 30
Step-by-step explanation:
1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)
so q(x) = -3x - 4
(q °p)(x) = -3 (-2x+4) -4 sorry I can't find the actual circle thing symbol
now distribute to get the simplified equation:
= 6x -12 -4
= 6x - 16
because you're doing (q - p )(3), you would plug 3 for x into the new equation
6(3) - 16 = 2
and thats you're answer for the first one
for the second one its the other way around, so you're putting all of q(x) into p(x)
take p(x) : -2x+4
and now replace the x with the entire q(x)
so (p - q)(x) = -2 (-3x-4) +4
simplify: = 6x+8+4 = 6x+12
so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation
= 6(3)+12 = 30
lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)
A teacher orders homework books for her class of 30 students.
The total value of the order is $135.
Two more students join her class, so she orders two extra books.
What is the total value of the order now? $
Answer:
The total value of the order now is $142.
Step-by-step explanation:
assuming all books are at the same price
135 ÷30=4.5
2x4.5=7
135+7=142

I really need help ASAP!!I am just now doing my schoolwork for today, due to some distractions, can someone help me understand how to find the volume of basic shapes? I really need help, because I have been talking to someone most all day, and I need to finish a sheet about shapes' volume. If you could right the formula for that, that would be great.
answer:
so the basic formula to find volume in shapes would be length × width × height.
here is a example : ( i cant really make the shape 3D so lets just say it is )
__________________

| | 3

and because i cant make the shape 3D, the width will be 2
all you really need to do is multiply all of them together, for smaller numbers you shouldn't have to really use your calculator ( if you have a pretty good memory of your times tables then you shouldn't have to as least ) but with bigger numbers then i would recommend using your calculator if your teacher does lets you
5 * 3 * 2
= 30 units !
i hope this helps you and if you have anymore questions then please let me know! :)
