Answer:

x = 10

Step-by-step explanation:

Since these angles are vertical angles, we know that 40 = 3x + 10. Subtract 10 from both sides to get 30 = 3x. Divide both sides by 3 to get x = 10.

Answer:

x would be 10

Step-by-step explanation:

angles across from each other are always equal so x would be 10 because 3 times 10 is 30 and then add the other 10 to get 40

Answer: -$1465.5

Ms. Thomas pays the 'same' amount as her car loan each month through car payments.

Total amount payed at the end of the year for car loan = -$2931

Change in Ms. Thomas' savings account each month (with respect to car loan) =

-2931/12 = -$244.25

So, to to calculate the total change to Ms. Thomas's savings account balance after paying for car loan for six months, we will simply multiply one month's amount with 6:

-$244.25 x 6 = -$1465.5

Answer:

72 Wrong, so find how many are right with 135 total

Step-by-step explanation:

It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.

so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.

so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.

You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.
