Carl is having a party. He has bought 24 brownies and is making 6 more batches of brownies. The inequality below can be used to determine how many brownies, b, must be in each batch so that all 138 guests get at least 1 brownie. Determine which of the given values, if any, make the inequality true: b=10, b=15, b=20 *
Answer:
b = 20
Step-by-step explanation:
The computation is shown below
Given that
24+ 6b > 138
where
b = 10
b = 15
b = 20
So if we take b = 10
= 24 + 6(10)
= 24 + 60
= 84
B = 15
= 24 + 6(15)
= 24 + 90
= 114
B = 20
= 24 + 6 (20)
= 24 + 120
= 144
So if we take b = 20 the inequality would be true

Answer:
your answer would be 3/10.
Step-by-step explanation:
you divide both 9/30 by 3
Answer:
3/10
Step-by-step explanation:
The first step is to find the greatest common factor, in this case it's 3.
Then divide the 9 by 3, which is 3.
Next you divide 30 by 3 which is 10
When simplifying a fraction you don't flip the numerator and denominator, so you put the simplified values in their places and you get 3/10.

Answer:
[A] x² + 2x
[B] 2x² - 5x
[C] 6x² + 8x
[D] 6x² - 12xy
Explanation:
x(x + 2)Apply Distributive Law: a(b + c) = ab + ac
x(x + 2) = xx + x · 2
Simplify:
x² + 2x
x(2x - 5)Apply Distributive Law: a(b - c) = ab - ac
x(2x - 5) = x · 2x - x · 5
Simplify:
2x² - 5x
2x(3x + 4)Apply Distributive Law: a(b + c) = ab + ac
2x(3x + 4) = 2x · 3x + 2x · 4
Simplify:

6x(x - 2y)Apply Distributive Law: a(b - c) = ab - ac
6x(x - 2y) = 6xx - 6x · 2y

-Lilly Ketchmen
Answer:
x = 2 and y = -1
Step-by-step explanation:
simplify the first equation by dividing each term by -2
x - 3y = 5
now you can add this to 4x + 3y = 5 and the 'y-values' will be eliminated and you will have:
5x = 10
x = 2
substitute '2' for 'x' to solve for 'y':
-2(2) + 6y = -10
-4 + 6y = -10
6y = -6
y = -1

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?
Answer:
3/4 cups of Chocolate chips is needed
Step-by-step explanation:
Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?
From the above question:
2/3 cup of sugar = ½ cup of Chocolate chips
1 cup of sugar = x
Cross Multiply
2/3 cup of sugar × x = ½ cup of Chocolate chips × 1 cup of sugar
x = ½ cup of Chocolate chips × 1 cup of sugar/ 2/3 cup of sugar
x = 1/2 ÷ 2/3
x = 1/2 × 3/2
x = 3/4 cups of Chocolate chips
Therefore, for 1 cup of sugar , 3/4 cups of Chocolate chips is needed
