Answer: c = \frac {d + ab} {a}
Step-by-step explanation:
For this case we have the following equation:
a (c - b) = d
We want to solve the equation for the letter c.
To do this, we apply the distributive property:
ac-ab = d
Then, applying addition property of equality we have:
ac = d + ab
Then applying division property of equality we have:
c = \frac {d + ab} {a}
Answer:
CHRISTMAS TREES
Step-by-step explanation:
for each number in the matrix, start by subtracting 1, then divide the number you got by 2
F(4) = 4^2-5
f(4) = 4x4-5
f(4) = 16-5
f(4) = 11
Answer:
36.99 dollars
Step-by-step explanation:
7.50 x 4 = 30 dollars
6.99 x 1 = 6.99 dollars
30 + 6.99 dollars = 36.99 dollars
We will calculate the length of the hypotenuse using the Pythagorean theorem. Suppose that the hypotenuse = c, then:
c^2 = 6^2 + 3^2
c^2 = 36 + 9
c^2 = 45
c = square root of 45
c = square root of 9 * square root of 5
c = 3 * square root of 5 ; <em>square root of 5 = approximately 2,24</em>
c = 3 * 2,24 = 6,72 = 6,7
The correct answer is 6,7.
