Answer:
20
Explanation:
To estimate, we round. 102.3 rounds to 100 and 4.7 rounds to 5; this means we divide 100/5, which is 20.
What is an estimate of 23 times 67
1,500
The values of the x in the given equation are x = 6.46 and x = -0.46
<h3>Solving an equation </h3>
From the question, we are to solve the equation for x
The given equation is
(x+3)² -10 = 2
First, add 10 to both sides of the equation
(x+3)² -10 +10 = 2 +10
(x+3)² = 12
Now, take the square root of both sides to get
x + 3 = ±√12
∴ x = 3 ± √12
x = 3+√12 OR 3-√12
x = 3 + 3.46 OR 3 - 3.46
x = 6.46 OR -0.46
Hence, the values of the x in the given equation are x = 6.46 and x = -0.46

Answer:
w = -19
Step-by-step explanation:
-6w + 4(w +3) = 26
-6w + 4w + 12 = 26
simplify
-2w + 12 = 26
now get the variable and the numbers on different sides
-2w + 12 - 12 = -2w
26 + 12 = 38
-2w = 38
now divide each side by -2
-2w / -2 = w
38 / -2 = -19
w = -19
