Answer:
a)12
b)1/12
c)4/12
Step-by-step explanation:
a) the coin is a 1/2 and the dice is 1/6 so you times the bottom number and you get 12
b) since that is a exact one way to get it has to be 1/12 chance
c) so to only get a tails it would be 6/12 and less than 5 means you can get 1,2,3, and 4 so that is 4 ways out of 12 ways so its 4/12
isosceles, 2 equal side 2 equal angles
2x - 24 = x - 2
2x - x = 24 - 2
x = 22
The integers are 24, 25, 26, 27, and 28.
Answer:
Acording to the question,
Cost per cup = $1.29
Total number of cups = 12
Total cost of cups = 12 x 1.2 = $15.48
Cost of candies = $2.49 per cup
Total number of candies = x
Cost of nuts = $0.69 per cup
Total number of nuts = y
Equations :
x + y = 12 (because total cups of nuts and candies will be equal to 12)
2.49x + 0.69y = 15.48 (Total cost of the 12 cups should be 15.48)
<u>Step 1 : Find x in terms of y</u>
x = 12 - y
<u>Step 2 : substitute x in terms of y from step 1 in the second equation</u>
2.49x + 0.69y = 15.48
2.49 ( 12 - y) + 0.69y = 15.48
29.88 - 2.49y + 0.69y = 15.48
-1.8y = -14.4
y = 14.4/1.8
y = 8
Step 3 : Find x
x + y = 12
x = 12 - y
x = 12- 8
x = 4
Thus,Yumi should use 4 cups of candies and 8 cups of nuts.
Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let present age of father = f
Let present age of son = s
Equation No. 1 -
f = 3s
Equation No. 2 -
f + 15 = 2s
To begin with, we will substitute the value of ( f ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
f + 15 = 2s
( 3s ) + 15 = 2s
3s - 2s = - 15
s = - 15
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( f ).
Equation No. 1 -
f = 3s
f = 3 ( - 15 )
f = - 45
FINAL ANSWER:
Therefore, the present age of the father is - 45 years old.
It isn't possible for someone to be negative years old but this is the answer that I obtained from the equations.
Hope this helps! :)
Have a lovely day! <3
