Answer:
Step-by-step explanation:
15x + 121 = 256 the answer is x = 9
4x + 8 > 2x - 10 the answer is x > -9
5x + 7 = 42 the answer is x = 7
Answer:
Option A) 1.6t+0.5
Step-by-step explanation:
Let
t ----> the number of trophies
we know that
To determine the total weight of the box, multiply the number of trophies by the weight of each trophy and add the weight of the empty box.
The linear equation that represent this problem is

Step-by-step explanation:
arithmetic sequence.
an = an-1 + c = a1 + (n-1)c
c is in our case 2 (every new shape has 2 more vertices).
we have a a1 = 3.
an = 3 + 2(n-1)
so,
a21 = 3 + 2(20) = 3 + 40 = 43
the 21st shadow will have 43 vertices.
There's the obvious symmetry ultimately because the radii OA and OB are hypotenuses of congruent right triangles. We can just eyeball the figure and see AB=BC, at least approximately, so the full chord AC=9+9=18
Answer: A. 18 units
Answer:
n numbers, because we can use variables like l and w to represent the unknown length and width. Many expressions have more than one variable in them. The volume of a box without a lid is given by the formula V = 4x(10−x)2, where x is a length in inches and Rochelle has invested $2500 in a jewelry making kit.
