Answer:
15x - 52
Step-by-step explanation:
Hi,
All you have to do is combine like terms. 4x + 11x is 15x. 9 + (-61) is simply -52.
Hope this helps :)
Answer:
15x-52
Step-by-step explanation:
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
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

Zander uses an on-line store that sells songs for $1 each and movies for $6. He used all of his $20 allowance to buy 10 items. How many songs and how many movies did he buy?
Answer:
2 movies and 8 songs
Step-by-step explanation:
use the formula 1x + 6x = $20 and x + x = 10. so x has to equal to 10, so 1 times 8 is 8 and 6 times 2 is 12. The x’s (8 and 2) equal 10 which is what you were looking for. i don’t know if that made sense but i hope it did

Use the distance formula to find the distance between (4, 2) and (3,5). Use:
d=/(x2 – x,)+ (y2 – y.)?
Round to the nearest tenth ,, will mark brainist and will get points
Answer:
d = sqrt(x2-x1)^2 + (y2-y1)^2
d = sqrt(4-3)^2 + (-3)^2

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.
