Step-by-step explanation:
Answer:
x = 13
Step-by-step explanation:
Sum or interior angles of a triangle is 180,
6x + 19 + 5x - 15 + 3x - 6 = 180
6x + 5x + 3x + 19 - 15 - 6 = 180
14x + 19 - 21 = 180
14x - 2 = 180
14x = 180 + 2
14x = 182
x = 182 / 14
x = 13
Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
Answer:
a = 100
b = 5
Step-by-step explanation:
Just plug this into the equation it shows:
R(1) = (500 + (100)(1)) (50 - (5)(1))
Answer: 4 games
Step-by-step explanation:
Whether Denise bowls or not, he incurs rent for bowling shoes and per bowling he has to pay $4.75 while he rented shoes for $3.
Then the equation is:
y = 3 + 4.75x
Where
y is the total cost
x is Number of bowling
y = 3 + 4.75x
3 + 4.75x = 22
4.75x = 22 - 3
4.75x = 19
x = 19/4.75
x = 4
Denise bowled 4 games.
