21 \div 30 = 14 \div 14 + x
30 \times 14 = 420
21 \times 14 + x = 294 + 21x
420 = 294 + 21x
420 - 294 = 126
126 = 21x
126 \div 21 = 6
x = 6

The large triangle and the smaller one are similar. Comparing long sides to short ones, we get
.. (30 mm)/(21 mm) = (14 mm +x)/(14 mm)
.. (14 mm)*10/7 = 14 mm +x
.. (14 mm)*(10/7 -1) = x
.. (14 mm)*(3/7) = x = 6 mm

The value of x is 6 mm.

Solve 14(0.89)x+4.5 =162
dedylja [7]
So the first thing to do is to simplify both sides of this equation:
<span>12.46x+4.5</span>=162
Next we shall subtract 4.5 from both sides so:
<span>12.46x+4.5−4.5</span>=<span>162−4.5</span>12.46x=<span>157.5
</span>Now that we are done with all those steps now here is the final steps so now we shall divide both sides by 12.46:
<span><span><span>12.46x/</span>12.46 </span>= <span>157.5/<span><span>12.46
</span>Ok so your final answer shall be:
</span></span></span>x=<span>12.640449
</span>I hope this helps you greatly!

given the equation y=-2x^2+1. determine the direction of opening, coordinates of the vertex, Maximum or minimum value and the ax
Andreas93 [3]
The sign of the term in x^2 is negative  so the graph will open downwards.
when x = 0 y = 1
The coordinates of the vertex are (0,1)
the maximum value of the function is 1
and the axis of symmetry ix x = 0 (  the y axis)

How old am I if 250 reduced by 5 times my age is 50?
Korolek [52]
250 - 5(x) = 50

250 (-250) - 5x = 50 (-250)

-5x = -200

-5x/-5 = -200/-5

x = 40

hope this helps

you are 40 years old!
