The total value of a collection of nickels and dimes is $3.05. If the number of nickels is 19 greater than the number of dimes. Which equation determines how many coins there are of each kind?

 10d+5(d-19)=305

Step-by-step explanation:

let d = number of dimes; then,10d = the total value of the dimes

d + 19 = number of nickels; then, 5(d + 19) = the total value of the nickels

total value of dimes + total value of nickels = 305 cents

10d + 5(d + 19) = 305

answer: 7

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
