Question
15 is the same as the product of 3 and a number. Which equation models this sentence?
15=3x
15=x-3
15=3+x
15=x divided by 3
Answer:
<h2>
15=3x</h2>
Step-by-step explanation:
15 = 3x
x = 15 : 3
x = 5
.........................
check
15 = 3 * 5
15 = 15
the answer is good
(0,5.25)(10,13.75)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (13.75 - 5.25) / (10 - 0) = 8.5/10 = 0.85
y = mx + b
(0,5.25)...x = 0 and y = 5.25
slope(m) = 0.85
now we sub, we r looking for b, the y int
5.25 = 0.85(0) + b
5.25 = b
so ur equation is : y = 0.85x + 5.25 or C(t) = 0.85t + 5.25 <==
cost of a 12 min taxi ride.....sub in 12 for t
C(t) = 0.85t + 5.25
C(12) = 0.85(12) +5.25
C(12) = 10.20 + 5.25 = 15.45
so a 12 min ride would cost u : $ 15.45 <==
Answer:
I dont know what to say
Step-by-step explanation:
Amount from dimes would be: 0.1y
Amount from quarters = 0.25x
So, total amount = 0.25x + 0.1y
So, she is not correct
Hope this helps!
Answer:
y=29x+50; 30 months
Step-by-step explanation:
$920-50=870
870/29=30
