The last one bec when multiply the outside number by what’s in the parentheses u get x^2. the other equations get u x^4, x, x^3. quadratic is only x^2
1) If it is a function it equals x=6
2) If this one is also a function it would be x= -6
Please give a little more information so I can help you more!!!
Answer:
Total number of texts sent by each person is as follows;
Jose=14
Bon=56
Ann=48
Step-by-step explanation:
Step 1
Express the total amount of texts sent by each person as shown;
Let the number of texts sent be;
Jose=x
Bon=4 times as Jose=4×x=4 x
Ann=sent 8 fewer than jose=4 x-8
Total texts sent=118
Step 2
Express the total number of texts sent by all of them as show;
Total texts sent=amount sent by Jose+amount sent by Bon+amount sent by Ann
where;
Total texts sent=118
amount sent by Jose=x
amount sent by Bon=4 x
amount sent by Ann=4 x-8
replacing;
118=x+4 x+4x-8
118=9 x-8
118+8=9 x
9 x=126
x=126/9
x=14
Step 3
Substitute the value of x to get the number of texts sent by each individual;
amount sent by Jose=x=14
amount sent by Bon=4 x=(4×14)=56
amount sent by Ann=4 x-8=56-8=48
Total number of texts sent by each person is as follows;
Jose=14
Bon=56
Ann=48
Answer:
12
Step-by-step explanation:
48 times 2/3 gives you the amount of runners that dropped out in the first half of the race. take that number (32), and subtract it from the original. You should be left with 16. Then take 1/4 of the remaining runners (16 times 1/4, which is 4), and subtract it from 16. this gives you 12
