Answer:
-19
Step-by-step explanation:
If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: <em>(-4) - (5 * 3).</em>
Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.
Now the expression is <em>(-4) - (15).</em> Then, you do the subtraction. -4 - 15 is equal to -19.
Does that help?
Mason:
time = t
V = 6 ft/s
Distance = v * t = 6t
Nora:
time = t - 60 [ I passed 1 minute to seconds]
V = 8 ft/s
Dsitance = v*t = 8 (t - 60)
Both distance are equal
6t = 8(t-60)
6t = 8t - 480
8t -6t = 480
2t = 480
t = 480/2
t = 240 s
Mason had been swimming for 240 seconds when both had swan the same distance.
Answer:
y = 3/2x + 7
Step-by-step explanation:
The slops is rise over run, so in this case the slope is 3/2 because it goes up 3 units while going 2 units to the right.
The points (0,7) is on the y axis. This means that 7 is the y intercept
With this information, we can follow the format of the slope intercept equation: y = mx + b
m stands for the slope and b stands for the y intercept. Plugging the information in, our equation is:
y = 3/2x + 7
The answer is 12. sorry if i’m wrong
Answer:
90 goats
Step-by-step explanation:
Number of chickens in farm = (1/5) of 150
= 
= 1 * 30
= 30
Number of cows in farm =
= 1 * 30
= 30
Number of goats in farm = 150 - (30 + 30)
= 150 - 60
= 90
