Answer:
x=9
Step-by-step explanation:
The purple expressions are equal because they are Z angles.
So solve
2x + 15 = 5x - 12
=>
15 + 12 = 5x - 2x
27 = 3x
x = 27/3 = 9
Answer:
i am not seen your questions plz show in clearly
(Y) Number of buckets given away
(X) Number of gallons donated
Y = X/5 is the equation
If X = 30000 and y= X/5, then Y=30000/5=6000 buckets donated
Answer:
y²-2y+3
Step-by-step explanation:
We write the dividend, y³-y²+y+3, under the box and the divisor, y+1, to the left of the box.
We first divide y³ by y; this is y². We write this above the box, over -y². We multiply the divisor by y²:
y²(y+1) = y³+y²
This goes under the divisor. We then subtract:
(y³-y²)-(y³+y²) = -2y². We then bring down the next term, y; this gives us -2y²+y.
We then divide -2y² by y; this is -2y. This goes above the box beside the y² in the quotient. We then multiply the divisor by -2y:
-2y(y+1) = -2y²-2y
We now subtract:
(-2y²+y)-(-2y²-2y) = 3y. We bring down the last term, 3; this gives us 3y+3. We divide 3y by y; this is 3. This goes beside the -2y in the quotient. We then multiply this by the divisor:
3(y+1) = 3y+3. We then subtract: (3y+3)-(3y+3) = 0
This makes the quotient y²-2y+3.
Answer:
10 : 17
Step-by-step explanation:
Male runners = 35
Female runners = 50
Total runners = male runners + female runners
= 35 + 50
= 85 runners
What is the ratio of the number of female runners to the total number of runners?
Ratio of the number of female runners to the total number of runners = number of female runners : total runners
= 50 : 85
= 50 / 85
= 10/17
= 10 : 17
Ratio of the number of female runners to the total number of runners = 10 : 17
