Answer:
2. correct
3. addition property of equality
4. substitution property of equality
Step-by-step explanation:
You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.
The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the <em>Addition Property of Equality</em>.
Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the <em>Substitution Property of Equality</em>.
20n-n-11n =16
20n-12n=16
8n=16
n= 16/8
n=2
Answer:
No, 900 grams is 1.98416 Pounds
Answer:
610 seeds
Step-by-step explanation:
b + 5b + 10 = x
- if b = 1 pack of sunflower seeds, then b = 100
- with this in mind, substitute 100 in for b
100 + 5(100) + 10 = x
600 + 10 = x
610 = x
Answer:
Q = (9, 4 )
Step-by-step explanation:
Use the midpoint formula and equate to the coordinates of the midpoint.
M = (
) , (
)
let the coordinates of Q = (x, y ) , R = (- 7, 0 ) , then
= 1 ( multiply both sides by 2 )
x - 7 = 2 ( add 7 to both sides )
x = 9
and
= 2 ( multiply both sides by 2 )
y = 4
Thus Q = (9, 4 )
