Two equations are shown: • Equation 1: 3 4 (x−12)=12 •Equation 2: 3 4 y−12=12 Solve each equation. Then, enter a number in each

OverLord2011 [107]

Answer:

The required value of x = 28

The required value of y = 32

Step-by-step explanation:

The given two equations are :

$\frac{3}{4}(x-12)=12..........(1)\\\\\frac{3}{4}\cdot y-12=12...........(2)$

Now, we need to solve both the equations and find out the required values of both the unknowns x and y.

Solving equation (1) to obtain value of x. We have,

$\frac{3}{4}(x-12)=12\\\\\text{On cross multiplication, we get}\\\\\implies 3\times (x-12)=12\times 4\\\implies 3x -36=48\\\implies 3x=48+36\\\implies 3x=84\\\bf\implies x=28$

Solving equation (2) to obtain value of y. We have,

$\frac{3}{4}\cdot y-12=12\\\\\implies \frac{3}{4}\cdot y=12+12\\\\\implies \frac{3}{4}\cdot y=24\\\\\text{On cross multiplicatrion, We get}\\\implies 3\cdot y=24\times 4\\\implies 3y = 96\\\bf\implies y=32$

Hence, The required value of x = 28

And The value of y = 32

An isosceles right triangle has a base and height with the same length. If the area of the triangle is 32 square centimeters, ho

Juli2301 [7.4K]

Answer:

The base and height are both 8 cm.

Step-by-step explanation:

To find the area of a triangle, multiply the height and base, then divide this number by 2.

A = $\frac{bh}{2}$

( b is the base, h is the height, and A is the area )

Since you're given only the area (rather than the base and height), follow the steps backwards, like so:

1. Multiply the area of the triangle by 2.

32 * 2 = 64

2. Since the question specifies that the two sides you're solving for are equal in length, the number you're solving for equals 64 when multiplied by itself. Set up an equation using this information (with x representing the length of the base and height) and solve:

x * x = 64

x² = 64

x = $\sqrt{64}$
