Solve the system of equations using elimination.
3x-2y=5
x+2y=3
Answer:
x = 2
y = 1/2
Step-by-step explanation:
3x - 2y = 5
x + 2y = 3
We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.
4x = 8
x = 2
Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.
2 + 2y = 3
2y = 1
y = 1/2
Now we figured out y. I hope I helped!

Variables are the same. Only the constants add.
Evaluate 5.5r8.35s when r12 and s4.
Answer:
32.6
Step-by-step explanation:
when you plug in for s and r you will get 66-33.4 since 5.5 multiped by 12 is 66 and 8.35 multiplied by 4 is 33.4 .
then you subtract them and that's how you'll get your answer

Area of triangle:
A= 1/2*b*h
= 1/2 *(29)* (19)
= 1/2 *(551)
= 275.5 in^2
Area of rectangle:
A= l * w
= (29) * (10)
= 290 in^2
Total Area:
275.5 + 290 = 565.5 in^2
Hope this helps! Have a great day :)
Answer:
565.5 in
Step-by-step explanation:
The area for a rectangle is A = lw
So A = (29)(10)
A = 290
The area for a triangle is A = 1/2bh
So A = 1/2(29)(19)
A = 1/2(551)
A = 275.5
You combine the two numbers to get a total area of 565.5 in

student in jakes class were numbered in order from 1 to 24. Jake was asked to choose classmates numbered with multiples of 5 to be in his group. which number could be the number of class mates in his group.
Answer:
number 5 , 10, 15, and 20 could be in his group which is a total of 4 classmates. If Jake's number wasn't a multiple of 5 then there would be 5 classmates.
Answer is most likely 4 classmates!
Step-by-step explanation:
Well we just need to know all the multiples of 5 in between 1 and 24 so we can start counting
5
10
15
20
25 - Bigger than the range
This means that the number 5 , 10, 15, and 20 could be in his group which is a total of 4 classmates. If Jake's number wasn't a multiple of 5 then there would be 5 classmates

Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?
Confused.
Answer: 74 degrees Fahrenheit
Step-by-step explanation: the temperature outside was 13 degrees lower than 87 degrees, so 87 - 13 = 74
Answer:
74 degrees F
Step-by-step explanation:
Subtract the 87 - 13
This is because there are +13 degrees more than outside. So if you add 74 + 13 that were added by the thermostat, you get 87 degrees. Does it make sense?
Just subtract :)

The right hexagonal pyramid
has a hexagon base with equal-length sides. The lateral
faces of the pyramid are all triangles (that are exact copies of one another) with
heights of 18 ft. Find the surface area of the pyramid.
Answer:
Lateral area of the pyramid = 72 unit²
Step-by-step explanation:
Lateral surface means side part of pyramid. So we nee need to find area of 6 triangles with base 4 and height 6.
Lateral area of the pyramid = 6 x Area of 6 triangles with base 4 and height 6

What is the domain of the function shown in this graph?
Domain is the set of x. Therefore, the domain starts from least x-value or from left side to the right side.
In the graph, it shows that the domain is from x = 1 to positive infinity.
Therefore the answer is x >= 1
or [1,+infinity) as interval.

Answer:
x = 5 22/24 OR x = 5 11/12
Step-by-step explanation:
x - 3/4 = 5 1/6
To solve this we mush use inverse operations
x - 3/4 + 3/4 = 5 1/6 + 3/4
x = 5 22/24
x = 5 11/12
To add the fractions there has to be a common denominator.
1/6 x 4/4 = 4/24
3/4 x 6/6 = 18/24
Keep denominators the same and add the numerators.
If your teacher wants the answer not simplified the answer is
x = 5 22/24
If your teacher wants it simplified the answer is
x = 5 11/12
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
