Answer:
x=1
Step-by-step explanation:
4(-x+4)=12
-4x+16=12
-16 -16
![\frac{-4x}{-4} =\frac{-4}{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B-4x%7D%7B-4%7D%20%3D%5Cfrac%7B-4%7D%7B-4%7D)
x=1
Answer:
D
Step-by-step explanation:
So 5(2+7) equals 45
A. 2(5+7)=24
B. 2+7(5)=37
C. 5(2)+7=17
D.5(2)+5(7)=45
Only D equals 45
Hope I helped :D
Answer:
Step-by-step explanation:
Given the function f(x)=x-3
So we want to know the value of the function when
1. x=1
Then, f(x) =x-3
Let substitute x=1
f(1)=1-3
f(1)=-2
2. x=2
Then, f(x) =x-3
Let substitute x=2
f(2)=2-3
f(2)=-1
3. x=4
Then, f(x) =x-3
Let substitute x=4
f(4)=4-3
f(4)=1
4. x=5
Then, f(x) =x-3
Let substitute x=5
f(5)=5-3
f(5)=2
5. x=8
Then, f(x) =x-3
Let substitute x=8
f(8)=8-3
f(8)=5
f(x)=x-3
x. 1 2 4 5 8
f(x). -2 -1 1 2 5
To do this question, you have to convert meters to kilometers because you can't add two different units of measurement together!
Remember that 1000m = 1km
That means 220 m = 0.220 km
(220 / 1000)
Since Larry ran 0.220 km further than Leigh, add 0.220 km to 2.3 km
0.22 km + 2.3 km
=2.52 km
Hope this helps :)
Well, since the two triangles are congruent, angles DBC and ACB are equal to each other.
So, 30=4y + 2
Subtract 2, 28=4y
Divide by 4, 7 = y
Now since all angles in a triangle are equal to 180 you can do :
180 = (45 + 3x + 30)
Simplify, 180=3x +75
Subtract 75, 105 = 3x
Divide by 3, 35=x
