Answer:
525 ml
Step-by-step explanation:
.25(700) = 175 ml drunk
700 - 175 = 525
Let the number of hamburgers = h
Let the number of cheeseburgers = c
Now we translate the given information into equations.
"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770
<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70
The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350
Answer: 350 hamburgers were sold on Monday.
Answer:
-3
Step-by-step explanation:
Simplify the following:
(-9 (-5) - 9)/(-12)
-9 (-5) = 45:
(45 - 9)/(-12)
| 3 | 15
| 4 | 5
- | | 9
| 3 | 6:
36/(-12)
The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):
3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:
Answer: -3
$3-$2.50=$0.50 (difference in $ of each hot dog and hamburger)
take 25 total as all hamburgers
25x $2.50=$62.50
$70.50-$62.50=$8
$8 ÷ $0.50 = 16
16 hot dogs, 9 hamburgers
Check :
16 x $3 = $48
9 × $2.50 = $22.50
$48+$22.50=$70.50
