Answer:
n=-4/3
Step-by-step explanation:
So the equation is -2/3n+7=15
First you subtract 7 from both sides: -2/3n+7-7=15-7 : -2/3n=8
Next multiply by 1/-2 on both sides, canceling out the -2 on the left and dividing 8 by -2 on the right: 3n=-4
Next divide by 3 on both sides
Answer: n=-4/3
Answer:
Step-by-step explanation:
You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is
Filling in:
and
and
Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:
which is choice D.
Answer:
y = -21/8 or as a decimal y = -2.625
Step-by-step explanation:
<u>Step 1: Distribute</u>
4(2y - 1) = -25
(4 * 2y) + (4 * -1) = -25
8y - 4 = -25
<u>Step 2: Add 4 to both sides</u>
8y - 4 + 4 = -25 + 4
8y = -21
<u>Step 3: Divide both sides by 8</u>
8y / 8 = -21 / 8
y = -2.625
Answer: y = -21/8 or as a decimal y = -2.625
Answer:
30-6x=12
Step-by-step explanation:
30 (was the original)-6(the amount of coffee)x(the price of each coffee)=12(the remaining amount after those 6 cups)
hope this helps!!
