Answer: because you don't have a value for Becka's age it would be a variable which is a letter so let's just say X

less than is a turn around word so it won't be 6 - X
your answer would be X-6

What is the decimal representation of 5/11

Answers

Answer:

$(5)/(11)=0.\overline{45}$

Step-by-step explanation:

Given: $(5)/(11)$

We need to change given fraction into decimal.

$x=(5)/(11)-------(1)$

$11x=5$

Multiply both sides by 9

$99x=45-----------(2)$

Add equation (1) and (2)

$99x+x=45+(5)/(11)$

$100x=45.45.....$

Divide both sides by 100

$x=0.454545.....$

$(5)/(11)=0.454545.......=0.\overline{45}$

0.45 is the answer but
0.45454545454is it

Eight times a number increased by 9 is the same as 15 more than 7 times the number. Find the number.

Answers

Haven translated the word problem into an algebraic expression, the unknown number is 6.

Let the number be n.

In this exercise, you're required to find an unknown number by writing an algebraic expression for the word problem and solve for the unknown number.

Translating the word problem into an algebraic expression, we have;

Eight times a number increased by 9:

$8n + 9$ ....equation 1.

15 more than 7 times the number:

$7n + 15$ ....equation 2.

Next, we would equate the two equations since we were told that they are the same.

$8n + 9 = 7n + 15\n\n8n - 7n = 15 - 9\n\nn = 6$

Therefore, the unknown number is 6.

Answer:

the number is 6

Step-by-step explanation:

8x+9=15+7x

8x-7x+9=15+7x-7x

x+9=15

x+9-9=15-9

x=6

You buy a bicycle helmet for $22.26, which includes 6% sales tax. The helmet is discounted 30% off the selling price. What is the original price

Answers

If you paid $22.26 after the discount and tax then 30% is 0.30 and 30% OFF is 1-0.30=0.70
Tax is 6% or 0.06 and along with the initial is 1+0.06=1.06 so P is original price in P×0.70×1.06=22.26
P×0.742=22.26
P=$30 was the original price

Answer:

$30
