answer of this question
Solve the following system of equations using the substitution method
y - 3x = 12
y = - 3
Answer:
x = 5
y = -3
as an ordered pair: (5,-3)
Step-by-step explanation:
if y = -3, then replace y in the first equation with -3.
-3 - 3x = 12
move -3 over to the other side by adding 3 to both sides.
3x = 15
x = 5
y = -3
Answer:
x = -5
y = -3
Step-by-step explanation:
Two equations
Solve using substitutition
y = -3
y - 3x = 12
_____________________
Since the first equation has y alone, we can plug it into the second equation for y.
(-3) - 3x = 12
-3 - 3x = 12
Add 3 to both sides :
-3x = 15
Divide -3 from both sides to get x alone :
x = -5
Now that we have x, plug it into x in the second equation :
y - 3(-5) = 12
y + 15 = 12
Solve for y :
Subtract 15 from both sides :
y = -3

the mass of a plastic triangle is 3g and rhe mass of a plastic square is 7 g Samson has a collection of plastic triangles and squares if there are 14 triangles and squares altogether and their combined mass is 58 g calculate how many triangles and how many squares Samson has.
Answer:
4 squares
10 triangles
Step-by-step explanation:
t=3g
s=7g
t+s=14 t=14-s
3t+7s=58
substitute
3(14-s)+7s=58
42-3s+7s=58
reduce
4s+42=58
4s=16
s=4
t=14-4=10
A group of students are going on a field trip. if the group takes 3 vans and 1 car, 22 students can be transported. if the group takes 2 vans and 4 cars, 28 students can be transported. write and solve a system of equations to represent the situation. fill in the blanks to indicate the number if students that can fit in each van and car?
Answer:
6 students.
Step-by-step explanation:
3v + c = 22 ---> c = 22 - 3v
2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28
2v + 88 - 12v = 28
-10v + 88 = 28
- 88 - 88
- 10v = - 60
v = 6 students

4 less than five-thirds of a number is no less than 21
Answer:
5/3-4>=21
Step-by-step explanation:
This is because it says no less than 21, meaning it says it does not want a number to be less than 21 but 21 is included.
On a scale drawing,1 in represents 8 feet. What is the actual length of a room that measures 3.4 inches
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2
Hope this helps! :)
Are the triangles below obtuse, acute, or right?
Answer: A is right. B is acute, C is obtuse, and D is right.
Step-by-step explanation:
The right triangles have the square in the corner.
Triangle C is a little bit bigger than a right triangle.
Triangle B is acute because its smaller than a right triangle.

What is the measure of A?
What is the measure of B?
<A = 72°
<B = 108°
Explanation :<A = <C
(5y - 3)° = (3y + 27)°
5y-3y = 27 + 3
2y = 30
y = 15
<A = (5y - 3)°
<A = (5 x 15) - 3
<A = 75 - 3
<A = 72°
<B + <A = 180°
<B + 72° = 180°
<B = 180° - 72°
<B = 108°
L.H.S of 2x - 3 = 8 is
Answer:
5.5
Step-by-step explanation:
2x -3 = 8
then
2x = 8 + 3 = 11
means
2x = 11
then
x = 11 ÷ 2
x = 5.5
___________________
we change the sign (- or +)
then take the number to the other side of the equal (with the changed sign)
leaving the x alone so that we can answer the equation..

f(x) = —x^2 – 3x
Find f(10)
Step-by-step explanation:
f(x) = —x^2 – 3x
f(10)={-10}²-3×10=100-30=70
Answer:
f(10) = 70
Step-by-step explanation:
In this question, plug in "10" to "x" and solve.
Solve:
f(10) = -(10)^2 - 3(10)
f(10) = 100 - 3(10)
f(10) = 100 - 30
f(10) = 70
Your final answer would be f(10) = 70

A triangle has side lengths of 23 in, 6 in, and 28 in. classify it as acute right or obtuse
Answer:
In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.
Step-by-step explanation:
if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.
if c^(2 )< a^(2)+b^(2) then the triangle is acute.
if c^(2 )= a^(2)+b^(2) then the triangle is right

help ASAP PLEASE i need to get a 100
Answer:
Alternate Interior ∠s: 3 & 5, 4 & 6.
Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.
Alternate Exterior ∠s: 1 & 8, 2 & 7.
Consecutive ∠s: 3 & 6, 4 & 5.
Step-by-step explanation:
Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.
Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.
Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.
Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.
Good luck.
