Answer:

$x + 5 \: + \: x \: + 6 \: + x + 7 = 2x - 1 + x + 7 + x + 7 + 2x - 1$

$3x + 18 = 6x + 12$

$18 = 3x + 12$

$6 = 3x$

$x = 6 \div 3 = 2$

$x = 2$

Romashka-Z-Leto [24]

Answer:

$10,318.62

Step-by-step explanation:

We have been given that works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. If he works over 40 hours during any week, he earns double his hourly wage.

Peter's hourly charges during 1st and 2nd week would be $33.19 and hourly charges during 3rd and 4th week would be 2 times $33.19.

First of all, we will find total hourly income as:

$\text{Total hourly income}=\$33.19(30+40)+2\times \$33.19(49+55)$

$\text{Total hourly income}=\$33.19(70)+\$66.38(104)$

$\text{Total hourly income}=\$2323.3+\$6903.52$

$\text{Total hourly income}=\$9226.82$

Now, we will find income from commission on sales as:

$\text{Income from commission on sales}=\frac{5.3}{100}(4500+5500+3800+6800)$

$\text{Income from commission on sales}=0.053(20600)$

$\text{Income from commission on sales}=1091.8$

Peter's total earnings is the last month: $\$9226.82+\$1091.8=\$10,318.62$

Therefore, Peter's total earnings in last month was $10,318.62.

Solve for x. Please help me.

mr_godi [17]

X=15 this is because 45+15 is equal to 60 and is equal to 4x so 4x=60 divide both sides by 4 to get x and you get x is equal to 15

A cylindrical roller with diameter 77 cm and height 1 m is used to level a rectangular park with dimensions22 × 11 . Find the nu

Vlad [161]

Answer: The number of revolutions required to level the park is 100.

Step-by-step explanation:

Given : Diameter of roller = 77 cm

Then radius of roller : r = $\dfrac{77}{2}\ cm$

Height = 1 m = 100 cm

Curved surface area of roller = $2\pi rh= 2\times\dfrac{22}{7}\times\dfrac{77}{2}\times100=24200\ cm^2$

Dimensions of park = 22 × 11 m

Then Area of park = $22\times11\ m^2= 232\ m^2=232\times100\times100 \ cm^2$

$=2420000\ cm^2$

Now , the number of revolutions required to level the park = (Area of park) ÷ (Curved surface area of roller )

$2420000\div 24200=100$

Hence, the number of revolutions required to level the park is 100.
