Answer:
a=8
Step-by-step explanation:
We are asked to solve this equation -90=-2(6a-3) . As here our variable is a , we will solve it for a. Let us do it step by step
1. Opening the brackets and distribution of -2 inside
-90=-12a+6
2. Subtracting 6 from both sides we get
-90-6=-12a+6-6
-96=-12a
3. Dividing both sides by 12 we get
Answer:
8.85 pounds
Step-by-step explanation:
Weight at birth = 2.95 pounds
After a six months, the sloth was three times heavier than it was at birth
New weight after six months = 3 × weight at birth
= 3 × 2.95 pounds
= 8.85 pounds
New weight after six months = 8.85 pounds
The sloth weighs 8.85 pounds after six months
Answer:
Step-by-step explanation:
We have been given an equation 
. We are asked to find the solutions of our given equation.
We will use splitting the middle term method to solve quadratic equation.
We will split middle term of our given equation into parts such that whose product is 
and whose sum is 3.
We know that such two numbers are 
.
Using zero product property, we will get:
Therefore, the solutions for our given equation are .
1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
<h3>What is the Commutative Property of Multiplication?</h3>
The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.
For example, a × b = b × a.
In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
<h3>What is the Commutative Property of Addition?</h3>
The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.
For example, 3 + 2 = 2 + 3.
Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
