Answer:
x = 30
Step-by-step explanation:
The figures are similar, thus the ratios of corresponding sides are equal, that is
= ( cross- multiply )
27x = 810 ( divide both sides by 27 )
x = 30
There's my answer
25/100
27/108
31/124
these three equal 1/4 or 1:4
I hope that right
Answer:
i'm not sure but try -5
Step-by-step explanation:
Answer:
<u>Using below system of inequalities</u>
<u>Following the rules </u>
- 1. Finding x- and y - intercepts
- 2. Connecting with dotted line for each as no equal symbol present in any inequality
- 3. Shade respective regions
- 4. Solution is the intersection of the shades regions
- 5. Select any three points in the solution region
<u>Line 1</u>
- y > 2x - 3
- x- intercept: y = 0 ⇒ 0 = 2x - 3 ⇒ 2x = 3 ⇒ x = 1.5
- y - intercept: x = 0 ⇒ y = -3
- Shaded region is above the line (or to the left)
<u>Line 2</u>
- y < x + 1
- x- intercept: y = 0 ⇒ 0 = x + 1 ⇒ x = -1
- y - intercept: x = 0 ⇒ y = 1
- Shaded region is below the line (or to the right)
<u>Selected points are:</u>
Simplify the equation to find X:
7/8 (-32 - 48x) +36 = 2/3( - 33x - 18) - 10x
Distribute the terms in parentheses:
-28 - 42x + 36 = -22x - 12 - 10x
Collect like terms
-42x + 8 = -32x - 12
Add 32x to both sides, and subtract 8 from both sides:
-10x = - 20
Divide both sides by -10
x = 2
