The <em><u>correct answers</u></em> are:

Supplementary; ∠2 and ∠3; substitution; 2.

Explanation:

Supplementary angles are angles whose measures sum to 180°.  Thus this is the first answer.  

Since we are told that ∠2 and ∠3 are supplementary, their measures sum to 180° and they are the second answer.

We know that m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.  We can substitute "m∠2 + m∠3" for 180° in the first equation; this is the substitution property.

To isolate m∠1 on the right, we will subtract m∠2 from each side, and get that m∠1 = m∠3 and the angles are congruent.

Suma a doua numere este 98 iar diferenta lor este 82 aflati cele doua numere​
Virty [35]

Answer:

90 and 8

Step-by-step explanation:

The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers

Let two numbers are x and y.

Sum of two numbers is 98

x+y = 98 ....(1)

The difference of two numbers is 82.

x-y=82....(2)

Adding equation (1) and (2) we get :

x+y+x-y=98+82

2x=180

x=90

Put the value of x in equation (1)

90+y = 98

y = 8

Hence, the two numbers are 90 and 8.

german

Answer:

-3, -1, 1

Step-by-step explanation:

The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.

From inspection of the graph, the curve intercepts the x-axis at

x = -3,  x = -1  and  x = 1

21(z+50)= 1,071 distrbultive property
Harman [31]

Answer:

The value of z is 1.

Step-by-step explanation:

Given:

21(z+50) = 1071

We need to solve the problem using distributive property.

Solution:

For the given equation we will apply distributive property;

By Definition of Distributive property which states that;

"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."

example = a(b+c) = a\times b +a\times c =ab +ac

So we get;

21\times z + 21\times 50 = 1071\\\\21z + 1050 =1071

Now by using Subtraction property we will subtract both side by 1050 we get;

21z+1050-1050=1071-1050\\\\21z=21

Now Dividing both side by 21 by using Division property we get;

\frac{21z}{21}=\frac{21}{21}\\\\z=1

Hence The value of z is 1.
