Answer:
148 pages
Step-by-step explanation:
5/9 of 333 is 185
333-185=148
First find the value of h, or the height using the pythagorean theorem.
13^2=15^2+h^2
289=225+h^2
h^2=64
h=8
Then use the formula bh/2 to find area of the triangle.
10*8/2=40
Final answer: A
Expand
4x - 28 = 0.3x + 0.6 + 2.11
Simplify 0.3x + 0.6 + 2.11 to 0.3x + 2.71
4x - 28 = 0.3x + 2.71
Add 28 to both sides
4x = 0.3x + 2.71 + 28
Simplify 0.3x + 2.71 + 28 to 0.3x + 30.71
4x = 0.3x + 30.71
Subtract 0.3x from both sides
4x - 0.3x = 30.71
Simplify 4x - 0.3x to 3.7x
3.7x = 30.71
Divide both sides by 3.7
x = 30.71/3.7
Simplify 30.71/3.7 to 8.3
<u>x = 8.3</u>
The decimal got smaller. .323 +782= 782.323
