Answer:
Correct, it is 15
Step-by-step explanation:
Because 3 turns into 9, you also want to multiply the other by 3, so you’d do 5x3 to get 15
Answer:
If you earn 15% the answer will be 10.8
Step-by-step explanation:
I know this because if you use the rule of 72 you will have to divide the two numbers together and the you will come out with 10.8
Answer:
Option (1)
Step-by-step explanation:



System of equations can be written as,


Therefore, system of equations given in Option (1) is the correct option.
The total value of all coins together is $2.7
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line
Let the number of nickels and quarters be x.
Value of nickel = 5 cents = $0.05
Value of quarters = 25 cents = $0.25
Thus, the total value equals
0.05x +$1.80 = 0.25x
$1.80 = 0.25x - 0.05x
$1.80 = 0.2x
x = 1.80/0.2
x = 9 coins
Thus the total value of all coins together is ($0.05+$0.25)x 9 = $0.3 x 9
= $2.7

Answer:
Step-by-step explanation:
If you flip coins, you can get,
HT TH HH TT
There are 4 possible outcomes.
Out of these 4, Matt has to do chores if two heads are flipped. It is 1/4 chance.
Out of these 4, Mark has to do chores if two tails are flipped. Again, 1/4 chance.
The method of decision is far since both guys have the same chance of being picked to do chores.
To flip again, they would have to get either HT or TH out of the 4 choices. So 2/4=1/2 is the likeihood they must flip again.
