Answer:
Quarter
Dime
Step-by-step explanation:
A nickel is 5 cents, and 5*5=25, so 5 nickels is 25 cents. A quarter is equal to 25 cents.
5*2=10, and a dime is equal to 10 cents.

lx-1 l ≤ 13
There are 2 solutions:
x-1 ≤ 13
and
x-1 ≥ -13
Solve each one
x-1 ≤ 13
add 1 to both sides of the equation
x-1+1≤ 13+1
x ≤ 14
x-1 ≥ -13
Add 1 to both sides:
x-1+1 ≥-13+1
x ≥ -12
-12 ≤ x ≤ 14
Answer:
30 cubes are added
Step-by-step explanation:
The image of the solid shape is attached.
From the Plan, Side elevation and Front elevation, the number of cubes needed to make the shape is 18 blocks. From the front elevation, 12 blocks is needed (4 * 3 blocks) while from the side elevation 6 blocks are needed given a total of 18 blocks.
The number of blocks needed to make the cuboid = 4 * 4 * 3 = 48 cm cubes.
Therefore the number of cubes to be added = 48 cubes - 18 cubes = 30 cubes.
30 cubes are added
First step is to mph into miles:
Turn 1hr and 40 min into a decimal:
1hr 40min ----> 1.6667hr
Then multiply:
300 x 1.6667 = 500.1
The distance is 500.1 miles.

Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (1, - 3) ← 2 points on the line
m = = = - 2
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 or
f(x) = - 2x - 1
