Answer: -4,-3

Step-by-step explanation:

You start at the point (1,4) on the coordinate plane. The first number is on the x-axis, which moves horizontally and is divided down the middle by the y-axis. The left side of the x-axis is negative, while the right side of the x-axis is positive. The second number is on the y-axis, which moves vertically and is divided in half by the x-axis. The upper half of the y-axis is positive, while the lower side of the y-axis is negative.

If you start at the point (1,4) then the x coordinate would be 1 and the y coordinate would be 4. So moving left by 5 units you would be subtracting 5 from the x coordinate. Similarly, by moving down seven units you would be subtracting 7 from the y coordinate.

Solve:

1 - 5 = -4

-4 is your x coordinate

4 - 7 = -3

-3 is your y coordinate

The coordinate (-4,-3) is your answer

A collection of nickels and quarters is worth 2.85 . There are 3 more nickels than quarters how many nickels and quarters are th
Zolol [24]

A nickel is equal to 5 cents or 0.05 dollars.

A quarter is equal to 25 cents or 0.25 dollars.

Let number of nickels be = n

Let number of quarters be = q

0.05n+0.25q=2.85    ...........(1)

As it is given, there are 3 more nickels than quarters so equation becomes,

n=q+3   ................(2)

Plug in the value of 'n' from (2) in (1)

0.05(q+3)+0.25q=2.85

= 0.05q+0.15+0.25q=2.85

0.30q=2.70

q=9

As n=q+3 we get, n=9+3=12

Hence, there are 12 nickels and 9 quarters.

Answer:

a = 33 degrees, b = 147 degrees

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees, and to solve for the angle on the other side of 109 degrees is 71 degrees, so to solve for a, have 180 minus 71 and 76. Then the sum of 71 and 76 is angle b since its the result of a subtracting from 180.
