Answer:
On E. the first answer is = -2.5x-15 and the solution is (-6,0)
Step-by-step explanation:
I just guessed this on E. and got it right.
-24
24 = 2 * 2 * 2 * 3
24 = 2^3 * 3^1
-64
64 = 2 * 2 * 2 * 2 * 2 * 2
64 = 2^6
-192
192 = 2 * 2 * 2 * 2 * 2 * 2 * 3
192 = 2^6 * 3^1
-175
175 = 5 * 5 * 7
175 = 5^2 * 7^1
<h2>x = 2 , y = 3</h2>
Step-by-step explanation:
As the given figure is a rectangle, therefore the opposite sides should be equal. So -
3x + y = 12 – y...(eqn (i) )
and
y – x = x – 1...(eqn (ii) )
Solving eqn (ii) we get -
→ y – x = x – 1
→ y = x + x – 1
→ y = 2x – 1...eqn(iii)
Solving eqn (i) we get -
→ 3x + y = 12 – y
→ 3x = 12 – y – y
→ 3x = 12 – 2y
Substituting the value of eqn (iii)
→ 3x = 12 – 2(2x– 1)
→ 3x = 12 – 4x + 2
→ 3x + 4x = 14
→ 7x = 14
→ x = 14/7
→ x = 2

Answer:
It is correct, the cost per granola bar is $0.25
Step-by-step explanation:
You would divide 12 and $2.99
2.99/12
Equals to 0.29166666(repeating)
You would then round the number since 0.2491666 is a correct money amount, making it 0.25.
$2.99/12 = $0.25 (rounded)
The cost per granola bar would be just under $0.25.
Hope this helps!
