Answer:
12
Step-by-step explanation:
Simplifying
18x + -6y = 12
Solving
18x + -6y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
18x + -6y + 6y = 12 + 6y
Combine like terms: -6y + 6y = 0
18x + 0 = 12 + 6y
18x = 12 + 6y
Divide each side by '18'.
x = 0.6666666667 + 0.3333333333y
Simplifying
x = 0.6666666667 + 0.3333333333y

Substitution:
X + 2y = 13
-2x - 3y = -18
Answer:
x = -3
y = 8
Step-by-step explanation:
x + 2y = 13 ------------(I)
x = 13 - 2y -----------(II)
-2x - 3y = -18 ----------(III)
Substitute x = 13 - 2y in equation (III)
-2*(13 - 2y) - 3y = -18
-2*13 - 2y *(-2) -3y = -18
-26 + 4y - 3y = -18 {Combine like terms}
-26 + y = -18 {Add 26 to both sides}
y = -18 + 26
y = 8
Substitute y = 8 in equation (II)
x = 13 - 2*8
= 13 - 16
x = -3
x = -3
y = 8

Answer:its B
Step-by-step explanation:
A punch bowl contained 2 liters of ginger ale, 1 liter of orange juice, and 1 liter of cranberry juice. Select all of the statements that are true. (Choose 2) 2 points The ratio of ginger ale to the entire punch bowl is 1 to 4. The ratio of orange juice to ginger ale is 2 to 1. The ratio of juices to ginger ale is 2 to 2. The ratio of the entire punch bowl to the juices is 2 to 4. The ratio of orange juice to the cranberry juice is 1 to 1.
Answer:
The ratio of juices to ginger ale is 2 to 2
The ratio of orange juice to the cranberry juice is 1 to 1
Step-by-step explanation:
Ginger ale = 2 liters
Orange juice = 1 liter
Cranberry juice = 1 liter
Total ratio = 2 + 1 + 1 = 4
The ratio of ginger ale to the entire punch bowl is 1 to 4.
Ginger ale : entire punch bowl
= 2 : 4
= 1 : 2
Not true
The ratio of orange juice to ginger ale is 2 to 1.
Orange juice : ginger ale = 1 : 2
Not true
The ratio of juices to ginger ale is 2 to 2.
juices : ginger ale = orange juice + cranberry juice : ginger ale
= 1 + 1 : 2
= 2 : 2
True
The ratio of the entire punch bowl to the juices is 2 to 4.
Entire punch bowl : juices 4 : 2
Not true
The ratio of orange juice to the cranberry juice is 1 to 1.
Orange juice : cranberry juice = 1 : 1
True
Which number is an irrational number?
A.) 3.5
B.) √36
C.) √48
D.) 37/100
Answer:
the answer is c
Step-by-step explanation:
square root of 36 = 6 = 6 / 1D. 37 / 100 is already a fraction. Hence, the only number that cannot be written as a fraction is the square root of 48. The answer is C: the square root of 48 is an irrational number.

The weight of 4 toys is 600g . The weight of 6 such toys are
Answer:
900g
Step-by-step explanation:
This is a case of direct variation as the weight will increase with the number of toys.
hence, 4/600 = 6/x
4x = 3600 (cross multiplication)
x = 900
Hence the weight of 6 such toys is 900g.
the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?
Answer:
8
Step-by-step explanation:
Let x = the unknown no.
Then
[tex]\frac{50}{20} = \frac{20}{x}[/tex]
50x = 400
x = 8
If the geometric mean of two numbers is 20, one number is 50 then the other number is 8
What is geometric mean?"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."
Formula to calculate geometric mean is
[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]
Here,
GM = 20
[tex]x_{1}=50\\ x_{2} =?[/tex]
Substitute the values in the formula
[tex]20=\sqrt{50.x_{2} }[/tex]
Squaring on both sides
[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]
Hence, the other number is 8.

Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?
Answer:
Sturdy's paper plates
Step-by-step explanation:
Let's see how much 8 plates cost:
Sturdy
24/3=8
$3.12/3= $1.04
Tough
32/4=8
$4.32/4=$1.08
$1.04<$1.08
Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.

What is the total surface area of the rectangular pyramid whose net is shown?
square inches
help me
Answer:
95 in.²
Step-by-step explanation:
Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle
Area of triangle = ½*base*height
base = 5 in.
height = 7 in.
Area of triangle = ½*5*7 = 17.5 in.²
Area of rectangle = Length*width = 5*5 = 25 in.²
Plug in the values
Total surface area of the rectangular pyramid = 4(17.5) + 25
= 95 in.²
