PLEASE HELP ASAP PLEASE!!!!

Mathematics
1 answer:
malfutka [58]2 years ago
5 0

Answer:

(3,2)

Step-by-step explanation:

2x-4=y

2y+3x=13

We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation

2(2x-4) +3x=13 : *distribute*

4x-8+3x=13 :  *combine like terms*

7x-8=13  * add the 8 to the other side*

7x=21 *divide*

x=3

So  the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3  we plug it into the other equation preferably.

2(3)-4 =y : 6-4=y : 2=y

We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.

2x-4=y         2(3)-4=(2)    2=2

2y+3x=13    2(2)+3(3)=13    13=13

Please help me with question 8 and part 1

Answer:

m∠B  = 95°

Scalene

Step-by-step explanation:

by definition, internal angles in a triangle must add up to 180°

in this case,

∠A + ∠B + ∠C = 180°

we are given ∠C = 55° and ∠A = 30°

30° + ∠B + 55° = 180°

∠B = 180 - 55 - 30 = 95° (Answer)

We can see that all 3 angles of the triangle are different. And hence we can conclude that all 3 sides of the triangle are different length (i.e it is not equilateral or isosceles). Hence it is a scalene triangle.

Suppose 15% of x equals 20% of y. What percentage of x is y ?
WINSTONCH [101]

Answer:

x = 133\frac{1}{3} of y

Step-by-step explanation:

Given:

15% of x equals 20% of y

So,

0.15x = 0.20y

so

x = 0.20 y / 0.15

x = 1.3333y

x = 133\frac{1}{3} of y
