The remaining balances in the first and second account are $5805 and $1020 respectively.

<em><u>Explanation</u></em>

Suppose, the initial balance in the first account was  x dollar.

As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u>  (9000-x) dollar

He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......

0.10x+0.60(9000-x)=2175\\ \\ 0.10x+5400-0.60x=2175\\ \\ -0.50x= 2175-5400= -3225\\ \\ x=\frac{-3225}{-0.50}= 6450

So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550

Thus, the remaining balance in the first account = 90% of $6450 = (0.90*6450)= \$5805

and the remaining balance in the second account = 40% of $2550 = (0.40*2550)=\$1020

Solve this equation 90x-60y is equal to 68 and 90x-70y is equal to 91​
Tanzania [10]

Answer:

Step-by-step explanation:

90x - 60y = 68.....multiply by -1

90x - 70y = 91

---------------------------

-90x + 60y = -68 (result of multiplying by -1)

90x - 70y = 91

---------------------------add

-10y = 23

y = -23/10 <===

90x - 60y = 68

90x - 60(-23/10) = 68

90x + 138 = 68

90x = 68 - 138

90x = - 70

x = -70/90

x = -7/9 <=====

Suppose 2 eggs with bacon cost 2.70 . One egg with bacon costs 1.80 . At thesebrates what will bacon alone cost
Leno4ka [110]

If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.

2. Given: mZABD = rº and mZACB = yo
Ede4ka [16]

Step-by-step explanation:

the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.

but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say

180 = ACB + ABC + CAB

180 = y + 180 - x + CAB

0 = y - x + CAB

x = y + CAB

x - y = CAB

therefore, the second answer option is correct.
