Answer with explanation:

The Mathematical Expression which is given here ,

  2 × (x+3)= 2 x + 6

We call this property as Distributive property of Multiplication with respect to Addition.

That is, →a × (b+c)=a × b + a × c, where ,a , b and c are any three real numbers.

We call it : ⇒The distributive postulate.

James estimated the total cost of groceries to be $50. The actual cost of the groceries is $65. What is the percent error? Round
Yuki888 [10]

The percentage error is 23%

Explanation:

The estimated total cost of the groceries = $50

The actual cost of the groceries = $65

To find the error value, we need to subtract the value of actual cost and total cost of the groceries.

Thus,

error value = actual cost - total cost

error value = 65-50=15

Hence, error value = $15

The formula to determine the percent error is given by

Percent error $=\left(\frac{\text { error value}}{\text {actual value}}\right) \times 100$

Substituting the values in the formula, we get,

$\begin{aligned} \text { Percent error } &=\left(\frac{15}{65}\right) \times 100 \\ &=0.231 \times 100 \\ &=23.1 \end{aligned}$

Rounding off the value, we have, 23%

Thus, the percentage error is 23%

Can someone help me with this? Thanks!
lana [24]

Answer:

b=4

Step-by-step explanation:

4b+5=1+5b (subtract 4b on both sides to get the b's together)

-4b         -4b

5=1+5b-4b (subtract 1 from both sides)

-1  -1

4=1b (divide by 1)

b=4
