3. Rewrite the expression as simply as you can:
3x + 11y - 2x - 4y
Answer:
x+7y
Step-by-step explanation:
First off, lets split the question into both x and y.
3x - 2x for the x
11y - 4y for the y
You can solve both of them to get x + 7y
3x - 2x = x
11y - 4y = 7y
Then, add them back up and get x + 7y
Answer:
x+7y
Step-by-step explanation:
3x + 11y -2x - 4y
(3x) + (11y) + (-2x) + (-4y)
(3x) + (-2x) = x
(11y) + (-4y) = 7y
3x + 11y -2x - 4y = x + 7y

Step-by-step explanation:
12) y = 4 + 7x
x = 3,-1
y = 4 + 7(3) = 25
13) y = x - 11
x = 72,
y = 72 - 11 = 61
14) y = 6x - 5
y = 6(-4) - 5 = -29
y = -11 (x = -1)
y = -5 (x = 0)
y = 13 (x = 3)
15) y = x + 1, each relation is a function

Answer:
no solutions
Step-by-step explanation:
6(x+1)=-2(3x+9)
distribute both sides first then you get:
6x+6=6x+18
then subtract 6x from 6x and 6 from 18.
0=12
therefore there are no solutions

C. 18
D. 22
Answer:
B. 13
Step-by-step explanation:
5 + 4 × 2 = 13
The correct option is (B).
What is PEMDAS rule?PEMDAS: Order of Operations
P: Solve the calculation or equation which are present in the parentheses or brackets like small brackets( ), curly brackets{ } or big brackets[ ]. Priority is given to brackets first.
E: Exponential expressions should be calculated first before the operations of multiplication, division, addition and subtraction.
MD: Then perform multiplication or division from left to right, whichever comes first in the equation.
AS: At last, perform addition or subtraction whichever comes first while moving from left to right.
Given expression,
5 + 4 × 2
According to order of operations:
Solving multiplication operation:
5 + 8
Now solving addition operation
= 13
Hence, after applying order of operations, the value of expression is 13.

Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the system. Write the equations in the order that they appear in the problem.
Answer: Required system
x+y= 30
0.25x+0.05y=5.10
Jude has 18 quarters and 12 nickels.
Step-by-step explanation:
Let x= Number of quarters
y= Number of nickels
As per given,
x+y= 30 (i)
0.25x+0.05y=5.10 (ii) [1 quarter = $0.25 , 1 nickel = $0.05]
Multiply 0.25 on both sides of equation (i)
0.25x+0.25y= 7.5 (iii)
Eliminate (ii) from (iii) , we get
0.20y=2.4
⇒ y = 12 [divide both sides by 0.20]
Put value of y in (i\), we get
x+12=30
⇒ x= 30-12= 18
Hence, Jude has 18 quarters and 12 nickels.
