The answer is Tuesday there will be 15 teachers for 179 students and 12 times 15 is 180
5.38 in expanded form is 5 + 0.3 + 0.08
Expanded form means you have to break it apart into addition.
1/4 converted into a decimal is .25
20÷.25=80
the answer is 80
Answer:
x = all real numbers
Step-by-step explanation:
first you need to solve the first equation to figure out what y is.
4x - y = 2
<em>add y to both sides of the equation</em>
4x = 2 + y
s<em>ubtract 2 from both sides of the equation</em>
4x - 2 = y
now that you know what y is, you can substitute it in the next equation.
3y = 12x - 6
3(4x - 2) = 12x - 6
<em>open the parenthesis </em>
12x - 6 = 12x - 6
<em>subtract 12x from both sides of the equation</em>
-6 = -6
regardless of what x is, -6 will always equal -6.
so, the answer is all real numbers.
ANSWER
(D)54.1°
EXPLANATION
The measure of angle P can be calculated using the cosine ratio.
We know the adjacent side to angle P to be 33.8 and the hypotenuse of the right triangle is 57.6 units.
Take cosine inverse,
To the nearest tenth, the measure of <P is 54.1°
