I need help with part 2 please
Ainat [17]

Answer:

$65

Step-by-step explanation:

So we already determined that the total cost C to drive m miles is:

C=0.25m+40

And we want to find the total cost of driving 100 miles.

So, substitute 100 for m and solve for C:

C=0.25(100)+40

Multiply:

C=25+40

Add:

C=\$ 65

Therefore, it will cost $65 to drive 100 miles.

Which of the following is NOT possible? A = A triangle where one angle measures 20 degrees and another angle measures 45 degrees
ArbitrLikvidat [17]

Answer:

C

Step-by-step explanation:

the angle measures of triangles must add up to 180 degrees. Since we are only given two angles, we can assume that all of the answers that add up to be below 180 degrees fulfill this requirement with the third angle. However, answer choice C adds up to 190 degrees on the first two angle, which means that no matter how low the third angle is, it will never add up to 180 degrees.

Jordan is saving to buy a computer that costs $425. So far she has saved $125, and she adds $20 to her savings each week. How ma
Ber [7]

Answer:

15 more weeks

Step-by-step explanation:

425 - 125 (what shes already saved)

300 divided by 20 (amount shes saving each week)

Result is 15, so 15 more weeks.

Hope this helped :)

If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.
