Let the variable x represent the answer.

85% $= 0.85 = 85 / 100$

$120/x=100/85$

$(120/x)*x=(100/85)*x$ 

- we multiply both sides of the equation by x

$120=1.17647058824*x$

- we divide both sides of the equation by (1.17647058824) to get x

$120/1.17647058824=x$ 

 $
x=102$

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m long.how many pieces of wood did jest

sveticcg [70]

Answer:

2 pieces

Step-by-step explanation:

Given

$Length = 1\frac{2}{3}m$

$Pieces = \frac{3}{4}m$

Required

Calculate the number of pieces

To do this, we have to divide the length of the wood by the length of each piece.

Represent this with x

$x= \frac{Length}{Pieces}$

$x= 1\frac{2}{3}/\frac{3}{4}$

Convert mixed numbers to improper fraction

$x= \frac{5}{3}/\frac{3}{4}$

Change division to multiplication

$x= \frac{5}{3}*\frac{4}{3}$

$x= \frac{20}{9}$

$x = 2.22$

$x = 2$

Ron what to make a rectangle basketball court if the length is 4 whole number 3/4 yd and the width is 3 whole number is 2/5 yd.

hoa [83]

A = L * W

A = 4 3/4 * 3 2/5.....turn them into improper fractions
A = 19/4 * 17/5
A = 323/20 or 16 3/20 yds^2 <==

What value of k makes the statement true? x² (2x³ + 7x²yª) = 2xªyª + 7x³y8?

Nina [5.8K]

By apply the distributive property of multiplication, the value of k which makes the statement true is 1.

<h3>What is the distribution property?</h3>

Mathematically, the distributive property of multiplication is given by tis expression:

x(y + z) = xy + xz.

Next, we would apply the distributive property of multiplication to the given equation by distributing to the left-hand side using xy⁴:

k(2x⁴y⁴ + 7x³y⁸) = 2x⁴y⁴ + 7x³y⁸

Dividing both sides by the common factor, we have:

k = (2x⁴y⁴ + 7x³y⁸)/(2x⁴y⁴ + 7x³y⁸)

k = 1.

In conclusion, the value of k which makes the statement true is 1.

How much longer, to the nearest minute, would it take to travel 290 miles at 60mph versus 70 mph.

velikii [3]

So using the equation distance = velocity * time
we get distance/velocity = time
60 MPH: 290/60 = 4.83333 Hours
60 MPH: 290/70 = 4.1429 Hours

Difference between them:
4.8333 - 4.1429 = 0.69 Hours, then multiply that by 60 and you get
41 Minutes.

Hope this helped!
*psst it would help if you gave me brainliest answer, I'm close to ranking up :) Thanks!
