Answer:
2
Step-by-step explanation:
Divide by 4 on each side.
4x/4 and 8/4
Now we have just x on one side and 2 on the other.
So, x = 2.
If you initially have 6 W, 4 R, and 8 B, and you take away two whites and a red, then you have 4W, 3 R and 8 B. There are 15 marbles total, and 8 black marbles, so you have an 8 in 15 or 53% chance of picking a black marble.
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:
D.
Step-by-step explanation:
the starting number is 370 and it gets multiplied by 1.11 every year so you would root the equation by t
Well 500 mm = 50 cm so if you add both segments together you will get a 50+30=80cm segment
