Substitutions y=x+4 y=3x+0

Mathematics
2 answers:
nordsb [41]3 years ago

Answer:

x= 2

y = 6

Step-by-step explanation:

to solve this system of equation using substitution method,

let

y=x+4............................................................. equation 1

y=3x+0............................................................. equation 1

substitute equation1 into equation 2

we have,

x + 4 = 3x + 0

combine the like terms

4-0 = 3x -x

4 = 2x

divide both sides by the coefficient of x which is 2

4/2 = 2x/2

x = 2

put x = 2 in equation 1

y=x+4............................................................. equation 1

y = 2 + 4

y = 6

therefore the value of x and y are 2 and 6 respectively

Answer:

x = 2

Step-by-step explanation:

since both equal y, you can set them equal to each other

x + 4 = 3x + 0

subtract x on both sides

4 = 2x

divide by 2 on both sides

2 = x

There was a triangle ABC with sides 15, 20, and 10. One of the sides of a triangle, which is similiar to ABC is 60. What are the
wlad13 [49]

Answer:

The possible pairs of sides are 90 and 120, 30 and 45, and 80 and 40.

Step-by-step explanation:

We know that 60 is a multiple of 15, 20, and 30, so we multiply by each factor to find all possible pairs: 10x6=60, 20x6=120, and 15x6=90, that gives your first pair, <u>90 and 120</u>.

We have now multiplied our first factor, 6. Now we need to multiply our second factor, 3: 20x3=60, 15x3=45, and 10x3=30. That gives your second pair, <u>30 and 45</u>.

Finally, we need to multiply by our 3rd factor, 4: 15x4=60, 20x4=80, and 10x4=40. That gives you your final possible pair, <u>80 and 40</u>.

I hope this helps :-)
