Answer:
x = 1
y = -7
Step-by-step explanation:
2x-3y=23
+ x+3y =-20
3x + 0 = 3
x = 1
(1) + 3y = -20
-1 -1
3y = -21
y = -7
Help please!! Asap!! i’ll give brainly!
Answer:
For 21: The first option (the uppermost) is correct for question 21. When it is no greater than, it implies that it can be equal to the number.
For 22: x+637 ≤ 2000, let x be the money he can spend for everything else.

A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk. Which expression represents the total cost, in dollars, to hire the dog walker for w walks?
Answer:
30 + 27(w)=189
Step-by-step explanation: w=7 btw (if u need it)
Brainliest?
The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30
Where 27w represents the cost of w walks.
Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

A dishwasher uses 11 liters of water for each cycle. A washing machine uses 5 times as much water as a
dishwasher uses for each load. Combined, how many milliliters of water are used for 1 cycle of
each machine?
Answer:
55,000 milliliters
Step-by-step explanation:
So if washing machine uses 5 times more than dishwasher
Dishwasher: 11 litters of each cycle
Washing machine: 11 x 5= 55 litters for each machine in litters
If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters
FORMULA for milliliter: multiply the volume value by 1000

Luca pays $165 per month for his car loan and an average of $2.30 per gallon of gas. He wants to keep his car expenses under $300 per month. Write and solve an inequality to find the greatest number of gallon "g", Luca can drive in a month while staying within his budget?
Answer:
58.69 gallons is the maximum she can get.
Step-by-step explanation:
165 + 2.3g ≤ 300
subtract 165 from both sides
2.3g ≤ 135
divide by 2.3 on both sides
g ≤ 58.6956521739

Answer:
n>-5
Step-by-step explanation:
We have to distribute the -7 first, so:
-105<-7(5-2n) becomes:
-105<-35+14n
To find n, we have to add 35, so:
-105<-35+14n
+35 +35
We get 14n>-70. Now, we have to divide each side by 14 to find n.
14n/14>-70/14.
So, the solution becomes n>-5.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (2, 720)(2,720).
Answer:
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].
Step-by-step explanation:
Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:
[tex]20 = a\cdot b^{0}[/tex] (1)
[tex]720 = a\cdot b^{2}[/tex] (2)
By dividing (2) by (1), we obtain the value for [tex]b[/tex]:
[tex]\frac{720}{20} = b^{2}[/tex]
[tex]b = \sqrt{\frac{720}{20} }[/tex]
[tex]b = 6[/tex]
And the value for [tex]a[/tex] is found by (1):
[tex]a = 20[/tex]
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

What is the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths?
Given:
One midsegment of an equilateral triangle.
To find:
The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.
Solution:
All sides of an equilateral triangle are same.
Let a be the each side of the equilateral triangle.
Length of the midsegment is equal to the half of the non included side or third side.
[tex]Midsegment=\dfrac{a}{2}[/tex]
The sum of two side is
[tex]a+a=2a[/tex]
Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is
[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]
[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]
[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]
[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]
[tex]\text{Required ratio}=1:4[/tex]
Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.

In ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°. Find the length of w, to the nearest centimeter.
Answer:
591
Step-by-step explanation:
The length of w from the given triangle UVW is 591 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² - 2bc·cosA.
Given that, in ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°.
w² = u² + v² - 2uv·cosW
w² = 480² + 180² − 2×480×180·cos120°
w² = 230400 + 32400 - 172800·(-0.5)
w² = 349200
w = √349200
w = 590.93
w = 591 cm
Therefore, the length of w is 591 cm.
