The sum of three consecutive integers is 42

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0

Answer:

The integers are 13, 14, and 15.

Step-by-step explanation:

Let the smallest one be x.

Then, the other two integers are x + 1 and x + 2.

x + x + 1 + x + 2 = 42

3x + 3 = 42

3x = 39

x = 13

x + 1 = 14

x + 2 = 15

The integers are 13, 14, and 15.

THE RIGHT ANSWERRRRRR
Mkey [24]
Area of semicircle = 1/2 the area of a circle:
A_{sc}=\frac{1}{2}  \pi  r^{2}
radius is half the diameter of 6ft.
A_{sc} = \frac{1}{2}  \pi  (3^{2} )=14.13 ft^{2} .
Area of the rectangle:
A_{r} =lw=15*6=90 ft^{2} .
Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.

PLS SOMEONE HELP PLSSS
Sav [38]

Answer:

x=17

Step-by-step explanation:

ok so since lines PR and RQ are congruent (we know because of the lines on them), that means angles P and Q are also equal.

now we can set up the equation to find x like this:

29+29+(8x-14)=180 (180 because the three angles of a triangle always equal 180)

x=17
