Answer:
Yes
Step-by-step explanation:
4 dozen cookies is 4*12 = 48.. Each cookies has 3 cookies. This requires 3*48 = 144. She has 4 jars of 40 each or 4*40 =160. So she has enough.
It’s B, because VKQ is equal to DKJ. VKQ is 153°, which makes DKJ 153°. But you’re trying to find DKM, which is 153°(the total degree) minus MKJ, the other half not including the one you’re trying to find. But we see a square there, a right angle, meaning that MKJ is equal to 90°
So we take the total of DKM (153°) and subtract it by the half that we know (which is MKJ, 90°) in order to find the half that we don’t know (DKM)
So it’s simply 153-90, which is 63°, so the answer should be B.
Hope this helped if you have other questions regarding this let me know! I know it seems a little confusing
The answer is:
Justin weighs 165 pounds.
Greg weighs 180 pounds.
If:
j - Justin's weight
g - Greg's weight
Then the system of equations is:
j + 15 = g ⇒ g = j + 15
1/2g = j - 75 ⇒ j = 1/2g + 75
We can replace j in the first equation:
g = <span>1/2g + 75 + 15
g - 1/2g = 90
1/2g = 90
</span>⇒ g = 90 ÷ 1/2 = 180
<span>
Thus, Greg weighs 180 pounds.
Now, using the first equation, we will calculate Justin's weight:
</span>j + 15 = g ⇒ j = g - 15
g = 180
Thus
<span>j = g - 15 = 180 - 15 = 165
</span>
Therefore, <span>Justin weighs 165 pounds.</span>
