Answer:
x= 48.75
Step-by-step explanation:
Add like terms
2x+2x and
2-17
4x-15=180
Now subtract -15 to both sides get x by itself
4x-15+15=180+15
4x=195
Now divide by four to each side to get x by itself again
4x/4 = 195/4
x=48.75
Answer:
Expression B
Step-by-step explanation:
<em>Let us find the information in the question</em>
- Alejandro has gon to school
of the last 35 days - We need to find the expression that represents the number of days Alejandro has gone to school.
<em>We must write the given information in an expression then look for it in the choices.</em>
∵ He has gone of 35 days
→ "of" means times (×)
∴ The days that he has gon = 35 ×
<em>The expression that can be used to determine the number of days he has gone to school is</em> 35 ×
The choices are:
A) 
B) 35 ×
C) ÷ 35
D) 
÷ 35
The answer is B
QUESTION:- WHICH FRACTION IS THE RECIPROCAL OF 
Answer:
1.12 Units
Step-by-step explanation:
1. Use cos(56°) = x/2
Make sure your calculator mode is in deg (degree) not rad(radians)
2. 2(cos(56°)) = x
3. x = 1.118385807
4. Round up to get 1.12 Units
Answer:
y = (-1/2)x
Step-by-step explanation:
As we go from (-4, 2) to (6, -3), x (the "run") increases by 10 and y (the "rise") decreases by 5. Thus, the slope of the line connecting these two points is m = rise / run = m = -5/10, or m = -1/2.
We adapt the slope-intercept form as follows: y = mx + b becomes
2 = (-1/2)(-4) + b, or
2 = 2 + b. Therefore, b must be 0. The desired eequation is y = (-1/2)x.
