Answer:
D. (-7)
Step-by-step explanation:
3(2 + f) = (-15)
(3 . 2) + (3 . f) = (-15)
6 + 3f = (-15)
3f = (-15) - 6
3f = (-21)
f = (-21)/3
f = (-7)

Answer:
b=-3
Step-by-step explanation:
The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)
<h3>Fraction</h3>
Her calculation:
- 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)
- 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)
- 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8
- 14 and StartFraction 5 over 8 EndFraction: 14 5/8
Her error was multiplying 7 by 2 and adding with 5/8(step 3)
Correct calculation:
7(2 + 5/8)
= 14 + 35/8
= (112+35) /8
= 147/8
= 18 3/8

Answer:
Yes, the ordered pair (1, 2) is a solution to the system.
Step-by-step explanation:
The answer can be found quite quickly. Simply substitute the x coordinate of the given pair for <em>x</em>, and the y coordinate of the given pair for <em>y</em>.
The x coordinate is 1 and the y coordinate is 2, so...
3(1) - 4(2) = -5
2=4(1)-2.
Next, simplify:
3-8=-5
This equation is TRUE.
2=4-2
This equation is also TRUE.
Hopefully, this helps in some way!
