+2.15.
Explanation: subtract 6.3 by 4.15 = 2.15 so you add 2.15
Answer:
23.8.
34 = (70:100)* 34 = (70* 34):100 = 2380:100 = 23.8. Now we have: 70 percent of 34 = 23.8.
Answer:
the answer of this question is 1/2
Answer:
There are 23 quarters and 37 dimes in the collection
Step-by-step explanation:
Let's name the two unknowns we need to find :
Q = number of quarters in the collection
D = number of dimes in the collection
So our first equation on the number of coins we have in the collection can be written as:
Q + D = 60
Now let's write an equation that takes care of the total value of the collection ($ 9.45), having in mind that each quarter is worth $ 0.25, and each dime is $ 0.10:
So let's solve this system of linear equations in "Q" and "D" by substitution. We use the first equation to solve for "d" for example, and then use this to substitute for D in the second equation:
Then, there are 23 quarters in the collection. We can find the number of dimes via the substitution equation we used:
Answer:
-36-128b
Step-by-step explanation:
Simply take -36 out of the parentheses to get -36-128b.
