<u>Answer:</u> The first number is 2, the second number is 3 and the third number is -2
<u>Step-by-step explanation:</u>
Let the first number be 'x', the second number be 'y' and the third number be 'z'
The equations according to the question becomes:
⇒ x + y + z = 3 ....(1)
⇒ x - y + z = -3 ....(2)
⇒ x - z = 1 + y ....(3)
Rearranging equation 3:
⇒ x - y = 1 + z .....(4)
Putting in equation 2:
⇒ 1 + z + z = -3
⇒ 1 + 2z = -3
⇒ z = -2
Putting this value in equation 4 and equation 1, we get:
⇒ x - y = -1
⇒ x + y = 5
Cancelling 'y' by eliminiation method and equation becomes:
⇒ 2x = 4
⇒ x = 2
Putting value of 'x' and 'z' in equation 1:
⇒ 2 + y - 2 = 3
⇒ y = 3
Hence, the first number is 2, the second number is 3 and the third number is -2
Answer:
99 yd
Step-by-step explanation:
When I add these, I line them up vertically
29 yd. 2ft. 11 in.
+ 55 yd. 1 ft. 10 in.
+ 13 yd. 1 ft. 3 in.
---------------------------
97 yd 4ft 24 in
We know that 12 in = 1 ft
so 24 in = 2ft
Subtract 24 in and add 2 ft
97 yd 4ft 24 in
+2ft -24 in
------------------------------
97 yd 6ft
We know 3 ft = 1yd
so 6ft = 2yd
Subtract 6ft and add 2 yd
97 yd 6ft
+2yd - 6ft
-------------------
99 yd
Answer:
False
Step-by-step explanation:
a>b
Let c> 0 then ac>bc because we are multiplying by a positive number
if c<0 then ac < bc because we are multiplying by a negative number we have to flip the inequality symbol
Since we do not know the value of c, we have to go with false
Answer:
1. $37.70 of interest
2. Jeans Junction
Step-by-step explanation:
1. For simple interest, we use the equation 
where
- P is the principle or starting value
- A is the total amount after interest and a period of time
- r is the rate at which interest gathers as a decimal
- t the time in years.
For this problem, we know P=$580, r=6.5%=0.065, t=1 year. We substitute into the formula and simplify to find the total amount A.
Using this total amount we can subtract the original principle to find the amount of interest.
617.7-580=$37.70 of interest
2. Jeans Plus sells jeans for $25 a pair At regular price, if I bought 3 I would spend 3j=s(25)=$75 and then received $10 off. SO I would spend $65 total.
Jeans Junction also sells jeans for $25 and will give me 15% off. This means I would pay 85% or 0.85 of the price (100-15=85). So if I buy 3, I would spend 3j=3(250=75. Then I can multiply 75(0.85)=63.75. This is the better deal because I spend less.
