Jermaine is saving $60 per week for a new guitar. The amount he has saved, s, is represented by

The area of a rectangle is 56 square centimeters. the length of the rectangle is 8 centimeters, and the width is three less than

telo118 [61]

From the question, we know that:
a = 56
l = 8
w = n - 3

To find the number (n), we should find the width (w) first
General formula of rectangle area is
l × w = a

Input the number to the formula
l × w = a
8w = 56
w = 56/8
w = 7

After finding the width, we find n
w = n - 3
n - 3 = w
n - 3 = 7
n = 10

The number is 10

Naddika [18.5K]

The Meaning of Slope and y-Intercept. in the Context of Word Problems. In theequation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept, where the line crosses the y-axis.

At a water park there is a slide that you really want to ride. In order to get to the top of the 29 foot slide you must first cl

murzikaleks [220]

Answer: 20 feet

Step-by-step explanation:

This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.

Solve with Pythagoras rule:

c² = a² + b²

c = hypotenuse

a= length

b = height

29² = 21² + b²

841 = 441 + b²

b² = 841 - 441

b² = 400

b = √400

b = 20 feet

Hey there :)

$1 \frac{4}{5} + 1\frac{6}{10}$

Change mixed fraction into an improper fraction
$\frac{9}{5} + \frac{16}{10}$
$\frac{16}{10}$ : are both even numbers, so you can further simplify by dividing by 2
$\frac{16/2}{10/2} = \frac{8}{5}$

To add fractions, we need same denominator to proceed. Here we have no problem since both denominators are 5

$\frac{9}{5}+ \frac{8}{5} = \frac{9+8}{5}$
$\frac{17}{5}$

As a mixed fraction: $3 \frac{2}{5}$
______________________________________________________

$2 \frac{3}{4} - 1\frac{2}{8}$

Let us change the mixed fraction into an improper fraction:
$\frac{11}{4} - \frac{10}{8}$
$\frac{10}{8}$ : You can further simplify this since both are divisible by 2
$\frac{10/2}{8/2} = \frac{5}{4}$

We have the same denominator set for subtraction, so you do not have to find common denominators
$\frac{11}{4}- \frac{5}{4} = \frac{11-5}{4}$
$\frac{6}{4}$

As a mixed fraction: $1\frac{2}{4} = 1\frac{1}{2}$
