Answer:
1 tens 3 ones
Step-by-step explanation:
All you do is count the numbers in the place value chart.
Since 31-18=13, all you do is count 10+1+1+1=13.
Equation- 2n+13=75
n is 31
Hope this helped.
The answer is <span>C. 9/25.
There are in total 25 marbles:
6 green + 9 red + 7 white + 3 black = 25 marbles.
There are 9 red marbles of the total 25 marbles. You can draw 9 red Thus, the probability of drawing a red marble out of the bag is 9 out of 25, which is 9/25.</span>
First, how much did you spend on the 8 gumdrops at 2 cents a piece?
8 gumdrops at 2 cents a piece is 16 cents
8 gumdrops x 2 cents = 16 cents
So, if you have 16 cents to spend on gumdrops and they are 8 cents a piece, how many can you buy?
16 / 8 = 2
You can buy 2 gumdrops for the same amount of money.
Step-by-step explanation:
let eqn be y = mx + b.
2x + 9y = 8
9y = -2x + 8
y = -2/9 x + 8/9
since the lines are perpendicular, product of the slope of the two lines = -1.
hence,
m x -2/9 = -1
m = 9/2
sub (0, -3):
-3 = 9/2(0) + b
b = -3
therefore equation is: y = 9/2x - 3
