Answer:

The first answer: 390m The second answer: x = 7; m<1 = 17; m<2 = 73

Step-by-step explanation:

First problem:

It's asking for the distance he walks by walking around a rectangular box which is the perimeter.

Two of the sides will have length 115m and two will have length 80m. So this perimeter is 115 + 115 + 80 + 80 = 390m.

Second problem:

Complementary angles add to 90 degrees. So m<1 and m<2 added together will equal 90

-4x +45 + 7x + 24 = 90

3x + 69 = 90

3x = 21

x= 7.

Plug back x into both m<1 and m<2 to find the measure of the angles.

m<1 = -4(7) + 45 = 45-28 = 17

m<2 = 7(7) + 24 = 49 + 24 = 73

how many integers from 100 to 999, inclusive, don't include the numbers 2,4,6,8? PLS HELP I WILL MARK BRAINLIEST
UNO [17]

Answer:

243

Step-by-step explanation:

999-100= 899 integers

200s 400s 600s 800s excluded so 400 numbers excluded

899 - 400 = 499

20s 40s 60s 80s which are 40 integers x 4 = 160

499 - 160 = 339

2s 4s 6s 8s which are 4 integers x 6 x 4 ( 4 from each 100 ) = 96

339 - 96 = 243 integers

Which expression is the factored form of 2/3x+4 ?
frosja888 [35]

Answer:

Option C.

Step-by-step explanation:

The given expression is

\dfrac{2}{3}x+4

We need to find the factored form of the given expression.

The given expression can be rewritten as

\dfrac{2}{3}x+(\dfrac{2}{3}\times \dfrac{3}{2})\times 4

\dfrac{2}{3}x+\dfrac{2}{3}(6)

It is clear that \frac{2}{3} is common.

Taking out common factors, we get

\dfrac{2}{3}(x+6)

It is the factored form of the given expression.

Hence, the correct option is C.

12.20x=372.10<br> Pls write exactly how to do it not just answer
ANEK [815]
To find x, you divide both sides of the equation by 12.20. This would look like this:
12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
