Which value of b makes the equation b4=12 true? A.48 B.16 C.8 D.3
The value of b that makes the equation b * 4 = 12 true is b = 3. Thus, the correct answer is option (D).
Let's apply each option and see which value of b makes the equation b * 4 = 12 true:
A) b = 48
48 * 4 = 192 (not equal to 12)
B) b = 16
16 * 4 = 64 (not equal to 12)
C) b = 8
8 * 4 = 32 (not equal to 12)
D) b = 3
3 * 4 = 12 (equal to 12)
Therefore, the value of b that makes the equation b * 4 = 12 true is b = 3.
Thus, the correct answer is option (D).

If Alfonso has a $10 bill. At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas. He gets $5.13 in change. The price of one banana is $0.32
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Alfonso has a $10 bill.
At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas
So $10.00-$1.99= $8.01
We need to find price of one banana.
He gets $5.13 in change.
$8.01-$5.13=$2.88
He used $2.88 to buy nine bananas
The price of each banana we will calculate by dividing $2.88 by 9.
$2.88/9=$0.32
The price of each banana is $0.32, Option A is correct.

5x + 3y = 9
4x - 2y = -6
Write as a ordered pair
Answer:
(0,3)
Step-by-step explanation:
Solving Simultaneously, 4(5x + 3y = 9)
-5(4x - 2y = -6)
then, 20x + 12y = 36
-20x + 10y = 30
adding the two equations we get,
22y=66, hence y= 3
then substituting y in one of the equations
5x + 3(3) = 9 hence x = 0
If y = - 10x +5, what is the slope?
