FIND VALUE OF X AND Y

Mathematics
1 answer:
Ainat [17]3 years ago
8 0

Answer:

x = 54

y = 114

Step-by-step explanation:

y = 114 because of the Corresponding Angles  Theorem:

"If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent."

(x + 12) + y = 180

x + 12 + 114 = 180

x + (126 - 126) = (180 - 126)

x = 54

Quick Check:

54 + 12 + 114 = 180 ✔

2(9n - 6) + 52 = 2(7n + 8)
STatiana [176]

Step-by-step explanation:

2×9n=18n

2×-6=-12

52-12+18n= 38 +18n

2×7n=14n

8×2=16

14n+16

38+18n=14n+16

subtract 14n from 14n and 18n

38+4n=16

subtract 38 from 38 and 16

4n=-22

divide each side by 4

n= -5.5

7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1

 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} 

 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1

 Answer:
 
7 times 1/7 equals 1

20 POINTS Compost costs $10 per cubic yard and topsoil costs $2 per cubic yard. Maria needs more than 10 cubic feet of topsoil.
Morgarella [4.7K]
I can't see the graph but let's use logic
hmm, more than 10 cubic feet of topsoil so the first and 2nd options are wrong

let's ee the costs
3rd option
10*1=10
2*12=24
10+24=34 and 34<50, that is fine

4th option
3*10=30
2*12=24
30+24=54
54>50, nope, that is over cost


answer is 3rd one
the one with 1 cubic yard compost and 12 cubic yard topsoil
