There are 20 purple(x) or yellow(y) marbles in a bag. The number of purple marbles is 4 less than 2 times the number of yellow marbles. Write a system of linear equations that represents the situation.
Answer:
There are 12 purple marbles and 8 yellow marbles.
Step-by-step explanation:
Let there are x purple and y yellow marbled in a bag.
x+y = 20 ...(1)
The number of purple marbles is 4 less than 2 times the number of yellow marbles.
x = 2y -4
x-2y = -4 ...(2)
Subtract equation (1) from (2).
x-2y-(x+y) = -4-20
-2y-y = -24
-3y = -24
y = 8
Put the value of y in equation (1).
x+8 = 20
x = 12
Hence, there are 12 purple marbles and 8 yellow marbles.
Divide. Write the quotient in lowest terms.

Answer:

Step-by-step explanation:
multiply 0 by 2 | 0 x 2 = 0
subtract 5 from 0 | 0 - 5 = -5
multiply 2 by 2 | 2 x 2 = 4
subtract 5 from 4 | 4 - 5 = -1
The table that represents the same linear relationship as the linear equation y = 2x - 5 is; Table A
What is the best table for the linear relationship?
The given equation is; y = 2x - 5
For the first table;
At x = 2, we have;
y = 2(2) - 5
y = -1
This and other values with input of x corresponds with the table.
For the second table;
At x = 2, we see that y = 1 instead of -1 and so this table is not correct.
For tables 3 and 4, we see that when we see that they both give the wrong values of y at x = 0 and so they are both wrong.

Answer:
x ≈ 32.4
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angle, adjacent side, and hypotenuse:
Cos = Adjacent/Hypotenuse
cos(72°) = 10/x
x = 10/cos(72°)
x ≈ 32.4

Given that KB = 28, what is the measure of angle KBL and segment KA
Answer:
KA = 28
∠KBL = 90°
Step-by-step explanation:
KA = KB (both are radii)
KB = 28, so KA = 28
∠KBL = 90° because tangents are perpendicular to the radius

Answer:
let a, c represent costs for adults and children, respectively12c+3a=162; 8c+3a=122Step-by-step explanation:
You are asked only for the setup, not the solution.
I find it convenient to use variable names that remind me of what they stand for. Here, we're asked for the admission prices for adults and children, so 'a' and 'c' are convenient variables to represent those values.
Let a represent the admission price for an adult.
Let c represent the admission price for a child.
__
The first sentence gives a relation between the numbers and the total cost:
162 = 12c +3a
The second sentence gives a different relation:
122 = 8c +3a
These are the "system of equations."
_____
You aren't asked for the solution, but it is (a, c) = (14, 10). It can be found easily by subtracting the second equation from the first.
