Your question: Which equation has solution x = -3?

I'd like you to know: I couldn't find any answer that exactly answered X=-3, although there is an answer similar to. But if it was accidental, this would be the most correct answer.

Answer: A) 2x - 7 = -1

|Step-by-step explanation|

2x - 7 = -1 = x=3
3x + 8 = 1 = x=-7/3
x + 8 = 10 = x=2
11 (2x-6) = -6 = x=30/11

Could someone help me complete this chart? It’s kinda confusing.

NARA [144]

Answer:

1. - completed

2. expanded = a · a · a · a

3. base = a | exponent = 5 | expanded = a · a · a · a · a

4. - completed

5. base = c | exponent = 3 | expanded = c · c · c

6. base = c | exponent = 4 | expanded = c · c · c · c

7. base = m | exponent = 2 | expanded = m · m

8. base = m | exponent = 3 | expanded = m · m · m

9. power = y⁵ | base = y | exponent = 5

10. power = y⁸ | expanded = y · y · y · y · y · y · y · y

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25

Quadrilateral ABCD is inscribed in the circle. Which sentence is true?

astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed quadrilateral in the circle , opposite angles will be supplementary

In this problem

Angle A and Angle B are supplementary angles

$m\angle A+m\angle C=180^o$

Angle B and Angle D are supplementary angles

$m\angle B+m\angle D=180^o$

therefore

The sentences that are true

A) A and B are supplementary

Find 3 consecutive odd integers whose sum is 225, explain please

aleksklad [387]

3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
