Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23
Answer:
A) ≈ 6.93
B) ≈ 0.02
Step-by-step explanation:
A)
Formula : a² + b² = c²
2.4² + 6.5² = c²
5.76 + 42.25 = c²
c = √48.01
c ≈ 6.93
B)
Formula = c² - a² = b²
1/3² - 1/4² = b²
1/9 - 1/16 = b²
b = √7/144
b ≈ 0.02

Answer:
I Believe you are correct
Step-by-step explanation:
Answer:
A.) 65x + 35X + 50 = 250
65x = cost of concrete per cubic yard, x is yd³
35X = cost of pouring/finishing concrete per cubic yard, X is yd³
50 = delivery cost
250 = the money you have
B.) 400 + 15n = 505
15n = amount of money you deposite per week, n is # of week
400 = some money in account after n week passed
505 = initial money in bank
C.) 1.1X - 10 = 55
55 = total cost of clothes
1.1X = tax rate where X is the undiscounted clothe cost
10 = discount
Y equals 3x-3 is the answer
