What value of m makes the equation true? 10m=10-5 (m-7)

2 answers:

7 0

Partially simplified, the equation says 10m + 5m = 10 + 45. Simplified further, it says 15m = 45. At this point, 45 is divided by 15 to isolate the variable. The answer is 3.

Answer:

The value of m makes the equation true is 3

Step-by-step explanation:

Given : $10m=10-5(m-7)$

To Find:What value of m makes the equation true?

Solution:

Solve the given equation

$\Rightarrow 10m=10-5(m-7)\\\Rightarrow 10m=10-5m+35\\\Rightarrow 10m + 5m =10+35\\\Rightarrow 15m =45\\\Rightarrow m = \frac{45}{15}\\\Rightarrow m = 3$

Hence The value of m makes the equation true is 3

Help please I have a test tomorrow!!!!

Taya2010 [7]

For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.

which order pair is a solution of the equation? y-4=7(x-6) A. only (5,4) B. only (6,5) C. both (5,4) and (6,5) D. neither

Svet_ta [14]

Answer:

option D. Neither

Step-by-step explanation:

y-4=7(x-6)

using (5,4):

4-4=7(5-6)

0=7(-1)

0=-7

using (6,5):

5-4=7(6-6)

1=7(0)

1=0

so option D is the answer
