Step-by-step explanation:

If ABCD is dilated by a scale factor of 1/2

then A'B'C'D' becomes half the size of ABCD

so if side D'A' is 3.5

Then D'A' = 1/2 DA

3.5 = 1/2 DA

DA = 7

Answer:

4/3

Step-by-step explanation:

You can simplify the exponent expression using exponent rules. The rules are:

A positive exponent is the number of times the base multiplies by itself.

A negative exponent is the number of times the base divides itself.

Multiplying same bases with exponents is simplified by adding the exponents.

Dividing same bases with exponents is simplified by subtracting the exponents.

A zero exponent always evaluates as 1.

can be simplified first using the negative exponent rule to move base with negative exponent to the other part of the fraction.

Now use the multiplication rule to simplify numerator and denominator.

$3.70

Answer:

$3. 70

Step-by-step explanation:

Each dime equals 10 cents. There are 7 dimes. 10+10+10+10=10+10+10= 70

Each quarter equals 25 cents. add 25, 12 times, 25,25,25,25,25,25,25,25,25,25,25,25=300. Just add a decimal.

Answer:

x = 6

Step-by-step explanation:

1.25(4x - 10) = 7.5

~Use the distributive property

5x - 12.5 = 7.5

~Add 12.5 to both sides

5x = 30

~Divide 5 to both sides

x = 6

Answer:

320 rolls

Step-by-step explanation:

Because there are ten boxes, and four packages fit into one box, 40 packages fit into ten boxes. If you then multiply 40 by 8, you get 320. You multiply 40 by 8 because 8 rolls of paper towels fit into one package.

Answer:

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The point at which the graph of the line y = 4x + 3 crosses the y-axis is 3.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line y = 4x + 3

The graph of the line crosses the y-axis when x = 0.

This is called the y-intercept.

There are two ways to get the y-intercept point.

From the definition of the equation of a line in slope intercept form we have,

y = mx + c

Where c is the y-intercept.

y = 4x + 3

So,

c = 3

We can also find the y-intercept when x = 0.

y = 4x + 3

y = 4 x 0 + 3

y = 3

Thus,

The point at which the graph of the line y = 4x + 3 crosses the y-axis is 3.

3)-3(v + 25) = 111

Use distributive property

-3v + (-3)*25 = 111

-3v - 75 = 111

Add 75 to both sides

-3v = 111+ 75

-3v = 186

Divide both sides by (-3)

v = 186/(-3)

v = -62
