Answer:
The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x i the height of a large block.
y is the height of a small block.
Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.
This means that:

Simplifying by 2:

So

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.
This means that:

Since 




The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
Answer:
A) 2x + y = -5
D) -2x = y
E) 2d = 4 - y
Step-by-step explanation:
The sample proportion is a point estimate of the population proportion. Therefore we need to convert the given percentage to a decimal fraction to find the best point estimate.
35/100 = 0.35
The best point estimate is 0.35.
Answer:
x = 16
Step-by-step explanation:
2x - 3 + 23 + 128= 180
Combine like terms
2x+148 = 180
Subtract 148 from each side
2x+148-148= 180-148
2x =32
Divide by 2
2x/2 =32/2
x = 16
