we are given

\frac{a}{b} (2x-12)=\frac{c}{d}

we can solve for x

We can isolate x

step-1: Multiply both sides by b/a

\frac{b}{a}*\frac{a}{b} (2x-12)=\frac{b}{a}*\frac{c}{d}

(2x-12)=\frac{bc}{ad}

step-2:Add 12 both sides

(2x-12)+12=\frac{bc}{ad}+12

2x=\frac{bc}{ad}+12

step-3: combine right side

2x=\frac{bc+12ad}{ad}

step-4:Divide both sides by 2

x=\frac{bc+12ad}{2ad}..............Answer

Find the area of the composite shape below.<br><br> a 66.8<br> b 91.92<br> c 101.12<br> d 101.6
Evgesh-ka [11]

Answer:

66.24 (This answer does not match to any of the options...)

Step-by-step explanation:

This shape can be divided into 2 different shapes. A triangle and a rectangle.

Area of a Triangle = \frac{1}{2} × base × height

= \frac{1}{2} × 8.8 × 7.8

= 34.32

Area of a Rectangle = Length × Width

= (19.2 - 7.8) × (8.8 - (3+3))

= 11.4 × 2.8

= 31.92

Total area = 34.32 + 31.92 = 66.24

Find the value of x in this equation. 25(4x − 3) − 2x = 45 − x
Charra [1.4K]

Answer:

x=40/33

Step-by-step explanation:

Let's solve your equation step-by-step.

25(4x−3)−2x=45−x

Step 1: Simplify both sides of the equation.

25(4x−3)−2x=45−x

(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)

100x+−75+−2x=45+−x

(100x+−2x)+(−75)=−x+45(Combine Like Terms)

98x+−75=−x+45

98x−75=−x+45

Step 2: Add x to both sides.

98x−75+x=−x+45+x

99x−75=45

Step 3: Add 75 to both sides.

99x−75+75=45+75

99x=120

Step 4: Divide both sides by 99.

99x

99

=

120

99

x=
