The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.
The explanation is:
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
4(m-3)+5(m+2)=m+9
Let's review the steps:
4m-12+5m+10=m+9 (step 1)
9m-2=m+9 (step 2)
8m =7 (step 3) (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>
Answer: b.97
97+37+46=180
Answer:
<h3>First line has y intercept -2 ( the blue line ) </h3><h3>Second line has y intercept 3 ( the red line )</h3><h3>The point where these two lines cross is "D"</h3>
Answer:
The larger number is 5.
Step-by-step explanation:
Let the numbers be represented by x and y. Then:
x + y = 8 is their sum, and
x² + y² = 34 is the sum of their squares.
Let's solve this system of equations using substitution. Since x + y = 8,
x = 8 - y. Subbing this 8 - y for x into the second equation, we get:
(8 - y)² + y² = 34, or
64 - 16 y + y² + y² = 34
Simplifying, we get first: 30 - 16y + 2y² = 0, and then:
2y² - 16y + 30 = 0, and after reducing, y² - 8y + 15 = 0.
This factors into (y - 3)(y - 5) = 0, and so y = 3 and y = 5.
The larger number is 5.
You either need to add the two times together or you need to subtract them
