Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20

Step-by-step explanation:
Classify the following triangle. Check all that apply.
I A. Obtuse
B. Acute
C. Scalene
D.slught
E. Isosceles
F. Equilateral
Answer: B. Acute and F. Equilateral
Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.
In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.

He'll end up paying 5,382 more than he borrowed.
Step-by-step explanation:
12 months in one year right so multiply 10 by 12.
You get 120 months in 10 years. Multiply $179.85 times 120 months.
Then you'll get the total amount he'll end up paying in those 10 years which is 21,582.
Subtract 21,582-16,200 and you get the amount of how much more money he'll end up paying which $5,382.

7-4[3-(4y-5)]
distributive property
Answer: =16y−25
Step-by-step explanation:
Distribute:
=7+(−4)(3)+(−4)(−4y)+(−4)(5)
=7+−12+16y+−20
Combine Like Terms:
=7+−12+16y+−20
=(16y)+(7+−12+−20)
=16y+−25
-2x + 3 – 5x – 4 = -3x – 8 + 10x

x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+3−5x−4=−3x−8+10x
Step 1: Simplify both sides of the equation.
−2x+3−5x−4=−3x−8+10x
−2x+3+−5x+−4=−3x+−8+10x
(−2x+−5x)+(3+−4)=(−3x+10x)+(−8)(Combine Like Terms)
−7x+−1=7x+−8
−7x−1=7x−8
Step 2: Subtract 7x from both sides.
−7x−1−7x=7x−8−7x
−14x−1=−8
Step 3: Add 1 to both sides.
−14x−1+1=−8+1
−14x=−7
Step 4: Divide both sides by -14.
A library has 2000 books. There are 3 times as many non fiction books as fiction books. Write and solve an equation. PLEASE HELP ASAP!!!???
Answer:
x = fiction books
3x = nonfiction books
x + 3x = 2000
After you solve for x, (which is the number of fiction books), you can plug its value into the equation for nonfiction books (3x) and that will give you the number of non fiction books.

ILL GIVE BRAINIEST find the solption for each system of equations using substitution. check ur solution in both original equations and make sure equations are in slope intercept form before u set them equal
y= -2x+6 and y=3x-4
check:
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
