The sum of four consecutive integers is 134. Find the integers. (please show your work)
lidiya [134]

Answer:

Integers: 32,33,34,35

Step-by-step explanation:

Consecutive means back-to-back, with a difference of 1

Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum

x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32

Therefore since x = 32, all four integers are:

32,33,34,35

If we check this, we can see that their sum equals to 134

32+33+34+35 = 134

Hope this helps!

2. Elena finds that the area of a house on a scale drawing is 25 square inches. The
likoan [24]

Answer:

The scale of the drawing is \frac{1}{9}\ \frac{in}{ft}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of an house on a scale drawing in square inches

y ---> the actual area of the house in square feet

z^2=\frac{x}{y}

we have

x=25\ in^2

y=2,025\ ft^2

substitute

z^2=\frac{25}{2,025}

simplify

z^2=\frac{1}{81}

square root both sides

z=\frac{1}{9}\ \frac{in}{ft}

therefore

The scale of the drawing is \frac{1}{9}\ \frac{in}{ft}
