Answer:

x = 7

Step-by-step explanation:

7x-1+6x=90

Combine like terms

13x-1 = 90

Add 1 to each side

13x-1+1 = 90+1

13x = 91

Divide by 13

13x/13 =91/13

x = 7

Sladkaya [172]

If we have 156 beads and we can make one bracelet with 9 beads we divide 156 by 9 and get 17 1/3. since we cannot have 1/3 of a bracelet, we can make 17 bracelets.

Sallie wants to purchase a skateboard. She has $115 to spend. She finds one that regularly sells for $137.99 and is on sale for

Elan Coil [88]

Sallie has $115 which is not enough to buy the skateboard as it costs $119.22

Step-by-step explanation:

Given,

Regular price of skateboard = $137.99

Discount = 20% = $\frac{20}{100}=0.2$

The discounted sale price of the skateboard without tax can be found by multiplying the regular price by <u>0.2</u>

Discount = 137.99*0.2 = $27.60

Discounted sale price = Regular price - discount

$Discounted\ sales\ price = 137.99-27.60\\Discounted\ sales\ price = \$110.39\\$

Sales tax = 8% = $\frac{8}{100}=0.08$

The total amount of sales tax can be found by multiplying the discounted sale price by <u>0.08</u>

Total cost with sales tax = 110.39*0.08 = $8.83

Total cost of skateboard = Discounted sale price + sales tax

Total cost of skateboard = $110.39+8.83 =\$119.22$

Sallie has $115 which is not enough to buy the skateboard as it costs $119.22
