Answer:
a) 231
b) 52.8
Step-by-step explanation:
210*.10 = 21. 21+210 = 231
48*.10=4.8 4.8+48 =52.8
So you would need to add:
500$ + 80$ + 175$ = 755$
Since John paid 900$ then you would subtract how much he is buying it for from how much Davis spent to fix it
900$ - 755$ = 145$ (on profit Davis earned)
First, substitute 6 in for x:
5 x 6^2 + 6 - 7
Simplify:
30^2 + 6 - 7
30^2 + 1
900 + 1
901
Hope this helps!!
I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6
