<span><span /><span>In this problem, it is stated that Darcy uses
block in order to show the value of the number.
Place value blocks are commonly used to help or support the students to
investigate the place value of the given number. It would be easy for Darcy to
use a material to know the number she’s looking for.
It says here that she used 4 thousand blocks and 500 hundred blocks.
Thus, the number she’s looking for is:
=> 4thousand + 5hundred
=>4000 + 500
=> 4500</span></span>
Answer:
yes it is
Step-by-step explanation:
Answer: b.
Step-by-step explanation:
Based on the information given, you can write the following expression:
Where k is the the constant of variation
If y=4/63 when x=3, then you can substitute these values into the expression and solve for k:
Substitute k into the expression. Then the equation is:
Substitute x=5 into the equation. Then, y is:
Answer:
Use the distributive property to write each expression as an equivalent algebraic expression:-
a.) 4(x + 5) = 4x + (4 x 5 ).
= 4x + 20 .
b.) 3(2x - 4) = 3 x 2x = 6x - (3 x -4 )
= 6x - 12 .
C.) -2(x - 6) = -2x - ( -2 x -6 ) .
= -2x - 12 .

Answer:
K = 3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
k−9=5(k−3)
k+−9=(5)(k)+(5)(−3)(Distribute)
k+−9=5k+−15
k−9=5k−15
Step 2: Subtract 5k from both sides.
k−9−5k=5k−15−5k
−4k−9=−15
Step 3: Add 9 to both sides.
−4k−9+9=−15+9
−4k=−6
Step 4: Divide both sides by -4.
-4k/-4 = -6/-4
K = 3/2
