Answer:

Step-by-step explanation:

y = 3x+4 and y = x-2

3x+4 = x-2

2x+4 = -2

2x = -6

x = -3

y = -3 -2 = -5

Which number is prime? 36 37 35 38

dybincka [34]

A number is prime if its only divisors are 1 and the number itself.

Out of your numbers, 36 and 38 are even, and thus divisible by 2, so they aren't prime.

Similarly, 35 ends with 5, so it's divisible by 5, and is not prime.

37 is divisible only by 1 and 37, and thus it's prime.

Olin [163]

Just do 8 1/3 divided by 5/9 or

25/3 / 5/9

25/3 * 9/5 = 5/1 * 3/1 = 15

So 15 tacos

* = times

I got the answer it is A I just need you to check it pls thank you

We have a circle of radius 5 m inside a square of side 10 m. The shaded area is:

$A_{\text{Shaded}}=A_{\text{Square}}-A_{\text{Circle}}$

Now, we calculate the area of the square and the circle:

$\begin{gathered} A_{\text{Square}}=10^2=100m^2 \\ A_{\text{Circle}}=\pi\cdot5^2=25\pi m^2 \end{gathered}$

Finally, the shaded area is:

$A_{\text{Shaded}}=100-25\pi\approx21.5m^2$

Between the time Iko woke up and lunchtime, tue temperature rose by 11 degrees. Then by the time he went to bed, the temperature

Ierofanga [76]

Answer:

$T_b=(x-3)\textdegree$

Step-by-step explanation:

let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let $T_b$ be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

$T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree$

Hence, the temperature relative to the time Iko woke up is (x-3)°
