2 1/4(4x-1)=1 3/5(1+4x)?? I need help with this problem. Thanks!!

koban [17]

Solving $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$ we get $x=\frac{77}{52}$

Step-by-step explanation:

We need to solve the problem: $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$

Solving:

$2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)\\\frac{9}{4}(4x-1)=\frac{8}{5}(1+4x)\\9x-\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}$

Add 9/4 on both sides:

$9x-\frac{9}{4}+\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}+\frac{9}{4}$

$9x=\frac{8}{5}+\frac{9}{4}+\frac{32x}{5}\\9x-\frac{32x}{5}=\frac{8}{5}+\frac{9}{4}\\\frac{9x*5-32x}{5}=\frac{8*4+9*5}{20}\\\frac{45x-32x}{5}=\frac{32+45}{20}\\\frac{13x}{5}=\frac{77}{20}\\x=\frac{77}{20}\times \frac{5}{13}\\x=\frac{77}{4*13}\\x=\frac{77}{52}$

So, Solving $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$ we get $x=\frac{77}{52}$

Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cool

kompoz [17]

<span>106% of $ _______ = $7.95

this means that 1.06 of the price of the cooler is 7.95

so we can assume th
</span>at the cooler price is x

then:

1.06 x = 7.95

Divide both sides by 1.06, we get:

x = 7.5

The price of the cooler itself without tax is $7.5

----.----.----

to check you answer:

7.5 + 7.5*6%= 7.5 + 7.5*0.06 = 7.5 + 0.45 = 7.95$

Correct!! :)

Sylvie and Bono hiked to the 6,288-ft summit of Mount Washington, then hiked to Carter Notch Hut for the night. Carter Notch Hut

igomit [66]

Answer:

- 3000 feets

Step-by-step explanation:

Given that:

Elevation at the summit of Mount Washington = 6288 ft

Elevation of Carter Notch Hut = 3,288 feets

The change of elevation in feets on the hike from summit to Carter Not hut:

Difference in elevation:

Summit at Mount Washington - Carter notch hut

6288 ft - 3288 ft

Change in elevation. = 3000 fts

Since the change decreased from 6288 to 3288, the elevation is downward and hence, negative = - 3000 feets
