We have a system of equations in two variables, namely, a and c. Use the substitution to find a and c.
Answer:
160
Step-by-step explanation:
In math, the word of means multiply. :)
3/8 * 640 = 240, so there are 240 1p coins.
there are the same number of 5P coins, so there are 240 5p.
640 - 1p - 5p = 2p
640-240-240 = 160, so there are 160 2p coins.
Answer:
r = 5 cm
Step-by-step explanation:
A = πr²
78.53 = (3.14)r²
divide by 3.14
25 = r²
r = ±5
r = 5
B. One is the answer because the longest line that would match is through c and b.
