Answer:

Option A) EF = 15 units.  

Step-by-step explanation:

We are given the following information in the question:

ΔABC ≅ ΔDEF

AB = 12, BC = 15, and AC = 17

If two triangles are congruent then they have the following properties:

AB = DE

BC = EF

AC = DF

\angle A = \angle D \\\angle B = \angle E \\\angle C = \angle F

Hence, by congruency:

BC = EF

EF = 15 units.

Thus, option A is the correct answer.

If two unrelated triangles, then C mainly because you're not given any information on DEF.
If ABC=DEF, then the answer would be A.

1. t+b=280
2t+3b=660
b=-t+280
2t-3t+840=660
-t=-180
t=180
b=100
He sold 180 tacos and 100 burritos
2. x=5 cent pencils
y=10 cent pens
x+y=1000
.05x+.1y=74.5
y=-x+1000
.05x-.1x+100=74.5
-1.5x=-25.5
15x=255
x=17
y=983
They sold 17 pencils and 983 pens

Ladonna is running for city council. She needs to get 5/6 of her votes from senior citizens and 54,000 votes in all to win .how
jasenka [17]
The first step to solve this question is to find out what 5/6 of 54000 is. So we multiply 5/6 by 54000. Why? Because there's the word "of" and "of" is usually associated in multiplication. So:

5/6 × 54000 = 45000.

So now we know that 5/6 of 54000 is 45000. So it means that she needs 45000 from senior citizens. But the question doesn't stop there, it also asks us to solve for the amount of votes she needs to win other than senior citizens.

Now we know that 45000 seniors need to vote for her we subtract 45000 to the total amount which is 54000.

54000 - 45000 is 9000.

So it means that she needs 9000 voters other than senior citizens to win the election for city council.

Which shows three ordered pairs that are all solutions of the equation y = x + 4?
svetoff [14.1K]
When x = 1, y = 1 + 4 = 5

When x = 3, y = 3 + 4 = 7
When x = 5, y = 5 + 4 = 9
When x = 7, y = 7 + 4 = 11

Therefore, the correct answer is option D.
