Answer:
D. 80x + 70 = 390
Step-by-step explanation:
80 times x (the degrees it heats up per minute times the number of minutes) + 70 (the degrees the oven was already at) = 390 (the number of degrees the oven needs to preheat to.)
This is the only answer that makes sense.
Hope this helps! :D
Also, where can I buy an oven that heats up this fast? XD
Okay so you can divide 7 by 2 which would equal 3.5 which is the same as $3.50. So let's focus on the apples first Joe can buy 3 apples with 50 cents left over. Next the bananas 0.75 you can divide 0.75 and 3.50 to see how many bananas he can buy but since we have 50 cents extra you can add that to 3.50 which adds to $4.00 . So 0.75 divided by 4.00 is 5.3 which can be rounded to 5 bananas. So Joe can buy 3 apples and 5 bananas.
hope that this helped you (;
Here is your answer
NO
Reason:
H.C.F. divides the L.C.M. completely.
Here 512 is not completely divided by 12
So, two numbers can't have their H.C.F and L.C.M as 12 and 512 respectively.

The answer is 16 because you have to solve for T which is 4 So you will multiply 4 times 4 because T is for 4 and you had to put parentheses around 4...4×4 is eight and you have to subtract 24-8 and it will give you 16
