25y.......140x
36y..........x
Cross multiply
25x= 36*140
25x= 5040
x= 5040/25
x= 1008/5
x= 201.6
When y=36 the x will = 201.6
I hope that's help !

Answer:
47/10 = 4 7/10
Step-by-step explanation:
3 2/5 + 1 3/10
1. Write mixed numbers as improper fractions:
17/5 + 13/10
2. Write equivalent fractions with a common denominator:
34/10 + 13/10
3. Add the numerators over the common denominator.
47/10
4. Simplify.
4 7/10
Answer:
-10.2n - 1
Step-by-step explanation:
We have two expressions in variable n and we have to add the two expressions.
An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.
Thus, the two given expressions add up to -10.2n - 1
Answer:
7. 5
pizza
8. B
9. 11
inches
10. -12
11. ![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
12. 4
Step-by-step explanation:
7. 3
+ 2 ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
make them mixed fractions:
+ ![\frac{17}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B8%7D)
get a common denominator by multiplying
by 4:
+ ![\frac{17}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B8%7D)
add the numerators: ![\frac{45}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B8%7D)
simplify the fraction by dividing 45 by 8: 5 ![\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D)
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 ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
multiply 7 by 1
: 11 ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
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: ![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
