Answer:
40
Step-by-step explanation:
let the number be 'x'
95 % of x = 38
(95 / 100)x =38
x = 38 × 100 / 95
x = 2 × 100 / 5
x = 2 × 20
x = 40
I NEED HELP WITH NUMBER 4 and I need to show work :((
Answer:
x = 1, y = 9
Step-by-step explanation:
y = 7 + 2x
4x + 3(7 + 2x) = 31
4x + 21 + 6x = 31
10x = 10
x = 1
y = 7 + 2(1)
y = 9

jordan cooked a 16 1/5 pound turkey in 5 2/5 hours. How many minutes per pound did it take to cook the turkey?
Answer:20 minutes per pound
we know that
To find the unit rate divide the total time by the total weight
Convert mixed number to an improper fraction
Convert hours to minutes
so
Find the unit rate
therefore
20 minutes per pound
-2, 7, 16 ..... Determine the general rule (Tn) for this sequence
Answer:
It is Tn = 9n - 11
Step-by-step explanation:
It is an arithmetic progression:
[tex]T_{n} = a + (n - 1)d[/tex]
a is the first term, a = -2
n is number of terms
d is common difference, d = 7-(-2) = 9
[tex]T_{n} = - 2 + \{ (n - 1) \times 9 \} \\ T_{n} = - 2 + 9n - 9 \\ T_{n} = - 11 + 9n \\ T_{n} = 9n - 11[/tex]
Answer:
[tex]T_{n}[/tex] = 9n - 11
Step-by-step explanation:
There is a common difference between consecutive terms, that is
7 - (- 2) = 16 - 7 = 9
This indicates the sequence is arithmetic with nth term
[tex]T_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 2 and d = 9 , then
[tex]T_{n}[/tex] = - 2 + 9(n - 1) = - 2 + 9n - 9 = 9n - 11
d. 3h =
h = 3.66 hours

The measure of an angle is 87°. What is the measure of its supplementary angle?
Answer:
180-87 = 93
Step-by-step explanation:
supplementary angles add up to 180°
so (the other angle + 87)=180°
other angle =180-87=93°
Answer:
93 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Therefore, the equation for finding the supplementary angle to 87 would be:
[tex]87 + x = 180\\x=180-87\\x=93[/tex]

Can someone pls explain what I’m supposed to do I don’t really understand
Answer:
There are only 3 differences perform
Step-by-step explanation:
I. If x is negative, y is negative then the answer is possitive
eg. x is -2, y is -3
-2 × -3 = 6
II. If x is negative, y is positive then the answer is negative
eg. x is -1, y is 2
-1 × 2 = -2
III. If x is possitive, y is possitive then the answer is positive
eg. x is 2, y is 5
2 × 5 = 10
Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer:
5
Step-by-step explanation:
Given:
Daily pass = $77Season ski pass = $450Skis = 2077 + 20 = 97
450 + 20 = 470
Keep multiplying 97 with random numbers until it passes 470.
97 × 4 = 388
97 × 5 = 485
So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.
Hope this helped.
