A nickel is worth 0.05 and a quarter is worth 0.25.
Multiply number of nickels by the worth and quarters by their worths. Add together to equal total value:
The equation is:
0.05n + 0.25q = $40
<span>Set the two equations equal to each other and solve for x
10x +50 = 8x +60
-50 -50
-----------------
10x = 8x + 10
10x = 8x + 10
-8x -8x
---------------
2x = 10
2x = 10
divide by 2 on both sides
x=5
five additional services are needed for the two companies prices to be equal

Answer:
361
Step-by-step explanation:
because the circumference is 19 must find the nearest tenth value is 361
First, you need to write out the problem. the sum (which is adding) of 4 times a number ( which we will call n) and 17 is 33. you would write it like this:
(4 x n) + 17 = 33
First, find out what 33 - 17 is. (it's 16)
4 times 4 is 16
(4 x 4) + 17 = 33
16 + 17 = 33
Answer:
1. 10√3
2. -√5
3. 21√3 -9√5
4. 12√7-√11
5. 8√5-3(√5*√4) = 8√5- (3*2)√5= 2√5
6. √5*√4 -√5= 2√5-√5= √5
7. 3√5*√9 +√5*√4 -√49*√5 = 15√5+2√5-7√5= 10√5
8. √6*√4 - √6*√9 + √16*√6= 2√6-3√6+4√6= 3√6
Hope it helps you :)
