110 just multiply 5 by 22
2x+1=13 x=6 so an ok answer would be: 2x+10=40 x=15
Answer:
$74.41
Step-by-step explanation:
x = Amount of money Sylvia had in her account
Amount of money spent at the Grocery Store= $25.89
Remaining Amount of money after Grocery = $48.52
Hence, By adding the two amount above we get the amount Sylvia had in her account before grocery;
x = $25.89 + $48.52
x = $74.41
Answer:
$5.50
Step-by-step explanation:
The function we are given is
p = 0.80n + 5.50,
where n is the number of balls.
Multiplying this variable by 0.80 means $0.80 will be the cost per ball. The additional amount added to the variable in the function, 5.50, will be the entrance fee.
Answer:
A. 36
Step-by-step explanation:
Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other
if the area of a triangle is hb/2,
(with h=length of height, b=length of base)
the height of the first triangle is:
25 = 10h/2
50 = 10h
h=5
you can write ratios representing the proportions of the two triangles:
5/x = 10/12 (with x=height of second triangle)
x=6
then find the area of the second triangle with the height (6) and base (12)
(6*12)/2 = 36
