Answer:
A has 263 calories
B has 257 calories
Step-by-step explanation:
system of equations:
a + 2b = 777
2a + b = 783
I multiplied the first equation by -2 to eliminate the 'a' terms
-2a - 4b = -1554
+ <u> 2a + b = 783</u>
-3b = -771
b = 257
solve for 'a'
a + 2(257) = 777
a + 514 = 777
a = 263
You just substitute in what x equals. ex. x=16, x-7 : 16-7=9.
x-7
1. x= -8; -8-7= -15
2. x= -11; -11-7= -18
3. x=16; 16-7= 9
Answer:
a: 16807
b: 0.0000595
Step-by-step explanation:
(a): We have 7 possibilities of numbers, and we need to choose 5 numbers that can repeat. So, for each of the 5 numbers, we have 7 possibilities. To determine how many codes are possible, we just need to multiply the number of possibilities of each of the 5 numbers, so we have 7x7x7x7x7, or 7^5, which is 16807 possibilities.
(b): to put the correct code in the first try, we need to find the exact combination (just one combination) among these 16807 possibilities, so the probability is 1/16807, which is 0.0000595, or 0.00595%.
Answer:
76°
Step-by-step explanation:
The opposite angles of a parallelogram are equal, so if one angle is 76°, then the opposite angle will be the same.

If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.
<h3>What was the equivalent discount?</h3>
Assume that the price of a good in the company was $10.
The initial discount of 30% takes the price to:
= 10 x ( 1 - 30%)
= $7
Then there is a 10% discount:
= 7 x (1 - 10%)
= $6.30
The equivalent discount is:
= (10 - 6.3) / 10
= 37%
