Answer:

x = 9

Step-by-step explanation:

combine all the equations and set it equal to 360

10x+ 7 + 88 + 127 + 5x+3 = 360

then combine like terms

15x + 225 = 360

then solve the equation by moving 225 to the right side of the equation

15x = 135

divide both sides by 15

x = 9

Answer:

x = 5.7 units

Step-by-step explanation:

By applying Sine rule is the triangle XYZ,

$\frac{\text{SinX}}{\text{WY}}=\frac{\text{SinY}}{\text{WX}}=\frac{\text{SinW}}{\text{XY}}$

$\frac{\text{SinX}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{SinW}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{Sin107}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{Sin107}}{\text{10}}$

$x=\frac{10\times(\text{Sin33})}{\text{(Sin107)}}$

x = 5.69

x ≈ 5.7 units

Henry has 15 lawns mowed out of 60 lawns. What percent of the lawns does Henry still have to mow?

Using is/of=%/100 15 lawns is what % of 60
15 over 60 = % over 100
Cross multiple and divide and you should get 25%
That percent means that 25% of the lawns are mowed, so 75%  of the lawns need to be mowed
