Solve the system of equations using elimination.
3x-2y=5
x+2y=3
Answers
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!

Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?
Confused.
Answers
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 :)

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

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!

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
Hope this helped...
Can someone really help me :(
Answers
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
