Answer:
130 dimes
Step-by-step explanation:
A nickel is worth 5 cents = 0.05n
A dime is worth 10 cents = 0.10d
Taliyah has 174 coins in her collection of dimes and nickels.
n + d = 174
n = 174 - d
The total value of the collection is $15.20.
0.05n + 0.10d = $15.20
We substitute 174 - d for n
Hence:
0.05(174 - d) + 0.10d = 15.20
8.7 - 0.05d + 0.10d = 15.20
- 0.05d + 0.10d = 15.20 - 8.7
0.05d = 6.5
d = 65/0.05
d = 130 dimes
The number of dimes she has in her collection is 130 dimes
Answer:
x = 24
y = 19
Step-by-step explanation:
2x - 8 = x + 16
x - 8 = 16
x = 24
2y = y + 19
y = 19
I believe it would be 8 X (100+30+2) hope that helps!
Answer:
y = 2x/3 +6
Step-by-step explanation:
using the formula y=mx+b .........where m is the slope, b is the is the point, where the line intersects the y axis
y = 2/3 x + 6
Answer:
The trigonometric values for cos are C = A/H, which means that to find cos(60), you need to divide the adjacent side by the hypotenuse, which in this case gives you 1/2, so that is the value of cos(60).
