X:y
2/10 = 4/x
Cross multiply
2x X= 10x4
2x = 40
Eliminate
2x/2 = 40/2
x = 20
Answer:
x=17/2 y=1/6
Step-by-step explanation:
-1(x+3y=9)
1(x-3y=8)
_________
-x-3y=-9
x-3y=8
________
-6y/6=-1/6 y=1/6
x+3(1/6)=9
x+ 1/2=9
- 1/2 - 1/2
x=17/2

Answer:
7. 5
pizza
8. B
9. 11
inches
10. -12
11. 
12. 4
Step-by-step explanation:
7. 3
+ 2 
make them mixed fractions:
+ 
get a common denominator by multiplying
by 4:
+ 
add the numerators: 
simplify the fraction by dividing 45 by 8: 5 
8. 3 x 6 = 18
5 x 6 = 30
7 x 6 = 42
9 x 6 = 54
therefore, y = 6x
9. 5:7 is similar to 8:L
divide 8 by 5: 1 
multiply 7 by 1
: 11 
L = 11
inches
10. 5 - 2x = 29
subtract 5 from each side: -2x = 24
divide each side by -2: x = -12
11. fruit = 15%
15% = 15/100
simplify by dividing by 5: 
12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
