7.5× 18.5=138.75 first week
7.5×20=$150 second week
total earnings 138.75+150=$288.75
She did multiply correctly 7.5 ×18.5 but got the wrong figure resulting in in lower pay and she did not multiply the 7.5 × 20 in the seond week. She shouldve added the week one and two wages to get her pay for 2 weeks

PLS HELP 15 POINTS

Anna's balance after writing check #1620 was B) $1606.42

Step-by-step explanation:

Step 1; Whenever you make a payment, make a cash withdrawal the money in your account decreases as you're giving your money to someone else. So the money spent or taken is reduced from the balance in your account.

Whenever you get your paycheck or make a deposit the money you have in your account increases. So the amount of money put in or the money you are paid is added with the balance you have in your account.

Step 2; Anna had a balance of $2,339.27 before writing the check #1620. She withdraws an amount of $732.85 under the description of  the city bank. As she withdrew money, withdrawn money is subtracted from the balance.

Balance after writing the #1620 check = Balance before writing the #1620 check - amount of money withdrawn = $2,339.27 - $732.85 = $1,606.42,

So her balance after writing check #1620 was $1,606.42.

3. G(Congruent means that it is the same size and shape)

4. E(Translation moves the whole shape including the points so that the shape and sizes remain the same)

Find the value of X in the triangle.<br><br> Please explain. Thanks.
Anna [14]
29°

triangles can only have 180°

This is a right triangle, so one angle is 90°, leaving us with 90° left

90°-61°= 29°
