Solve by substitution: y=5x-10 y=3x-2

Mathematics
1 answer:
olganol [36]3 years ago
7 0

Answer:

x=4 y=10

Step-by-step explanation:

y=5x-10

y=3x-2

We'll use the 2nd equation as a basis :

y=3x-2

3x-2=5x-10

0=2x-8

8=2x

4=x

We then use y=3x-2 to find y:

y=3(4)-2

y=12-2

y=10

How do i prove angle x and angle yzv are supplementary
yuradex [85]
Triangle XWV is an equilateral triangle(every angle is 60). So both angle V's are vertical angles, which means the are the same(60). Y is 90. So once you have 60 and 90 in triangle YZV, you know the last angle(Z) is 30. But since angle Z is 30 and angle X is 60, they are complementary and not supplementary(which adds up to 180)

The length and width of a rectangle are in a 4:7 ratio. the perimeter of the rectangle is 352. what are the length and width
Savatey [412]
Length = 4x
width = 7x
perimeter is 2length+2width= 352
2(4x)+2(7x) = 352
8x+14x =352
22x = 352
x = 16
then length = 4*16=64
width =7*16=112
