Hello!

To determine what time she has to take out the cookies, we can add 45 minutes to the time she puts them into the oven, which is 5:30 p.m. Remember that 1 hour is 60 minutes.

5:30 + 0:45 = 5:75

Since one hour is equal to 60 minutes, we have to move the extra minutes to the next hour, which is 6 p.m.

Therefore, Layla should take the cupcakes out at 6:15 p.m.

emmasim [6.3K]

Answer:

4ab

Step-by-step explanation:

4(-3b)(+a)+8ab÷2a×4a

4(-3ab)+8ab÷2a×4a

-12ab+8ab÷2a×4a

-12ab+4b×4a

-12ab+16ab

16ab-12ab = <u>4ab</u>

Someone please help! I have spent lots of time on this and I’m still confused
vfiekz [6]

Answer:

its the 3rd choice.

Step-by-step explanation:

Firstly, we find angle BDC (180-90-30=60)

Now that we found it we can use the sine rule to find DB (which i put as an x), which is sin60/14=sin30/x, by cross multiplication, we find that its equal to a decimal number, i will use its root version to this easier, its equal to 14sqrt3/3 inches.

And now we use the pythagorean theorem to find DC, we find that it is equal to 28sqrt3/3

Now, we find angle BAC (180-90-(30+15)=45)

Again, we use the sine rule to find AB (whom i will refer to as x and from whom we will subtract DB to find the length of AD), so we cross multiply in sin45/14=sin(30+15)/x, it is equal to 14.

So since AB-DC=AD

14-(14sqrt3/3)= 5.917096231 (and we ound that to a 5.9)

10x +2=7 what is the value of 2x
RoseWind [281]

Answer:

1

Step-by-step explanation:

10x + 2 = 7

10x = 7 - 2

10x = 5

x = 5/10 reduces to 1/2

2x = 2(1/2) = 1 <==
