Answer:

65+(-79)=-14

Step-by-step explanation:

The given expression is : 65-79

We can find the sum as follows:

65+(-79)=-14

Now, we have to write an addition expression that equivalent to this.

We can choose any expression like :

100+(-114)=-14

236+(-250)=-14

16+(-30)=-14

Step 3: Let LM = x. We know the lengths of the radii of each circle, so KL = 12 +
kow [346]

Answer:

Step-by-step explanation:

Step 3:

Let LM = x

OK = KP = 12 units [Radii of circle K]

LN = LP = 8 units [Radii of circle L]

Therefore, KL = KP + PL

KL = 12 + 8

     = 20 units

Step 4:

Since, ΔKOM and ΔLNM are the similar triangles,

By the property of two similar triangles, corresponding sides of these similar triangles will be proportional.

\frac{OK}{NL}=\frac{KM}{LM}

\frac{12}{8}=\frac{x+20}{x}

12x = 8(x + 20) [By cross multiplication]

12x = 8x + 160

12x - 8x = 160

4x = 160

x = 40

In order to solve the system of equations below, Harvey multiplies each equation by a constant to eliminate the x terms.
Karo-lina-s [1.5K]

Answer:

<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>

Step-by-step explanation:

Let's find out the constants to eliminate the x terms

7 x + 3 y = 5

2 x + 5 y = negative 11

Let's multiply the first equation by 2 and the second one by -7, this way:

2 * (7 x + 3 y = 5)

-7 * (2 x + 5 y = negative 11)

14x + 6y = 10

-14x - 35y = 77

<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
