From the graph it seems to be around the area of 10%.

So,

18,000 * 0.10 = $1,800

Graph the equation to solve the system. y=2x+7 1/2y=x+7/2

vlabodo [156]

Given equation is y=2x+7 and $\frac{1}{2}y=x+\frac{7}{2}$

Let's simplify the 2nd equation $\frac{1}{2}y=x+\frac{7}{2}$ before we can start graph so that calculation will be easy

$\frac{1}{2}y=x+\frac{7}{2}$

multiply both sides by 2 to cancel out fractions

$2*\frac{1}{2}y=2*x+2*\frac{7}{2}$

y=2x+7

which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.

y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

The science department orders a new telescope and pays $253.87 after tax. The tax rate is 6% . What was the original price of th

mash [69]

The price after tax is £253.87 so to find the original price you have to deduct 6% but first you need to find 6%.

Easiest way to find 6% is by finding 10% or 2% or 1% / whatever you find easiest. For me it would be 1%

If you find 1 % you would then multiple it by 6 to give you 6%

10% is £25.38 (move the decimals 1 unit)
1% is £2.54 (move decimals 2 units)
Always round up

£2.54 X 6 = £15.24

£253.87 - £15.24 = £238.63
