Answer:
4x+1
Step-by-step explanation:
sum= addition
one=1
and= plus
product of four and a number: when we say a number we usually use the variable x. 4(x)= 4x
put together: 4x+1 (no equal sign needed)
Answer:
<BAC = 78
<ABC = 68
Step-by-step explanation:
The remote angles theorem states that when one extends a side of a triangle, the angle formed between the extension and one of the sides of the triangle is equal to the sum of the two non-adjacent angles inside the triangle. One can apply this theorem here and state the following,
<BAC + <ABC = <ACD
Substitute,
(5y + 3) + (4y + 8) = (146)
Simplify,
9y + 11 = 146
Inverse operations,
9y + 11 = 146
-11 -11
9y = 135
/9 /9
y = 15
Now substitute this value back into the expressions to find the numerical measurement of (<BAC) and (<ABC),
<BAC = 5y + 3
5(15) + 3
78
<ABC = 4y + 8
4(15) + 8
68
Mid point is (-5,0), slope is -4, distance might be 8 but i’m really not sure about that sorry, can i please have brainliest
12 plus 12 (walk to and from her grandparents) times 2 (two times a week she goes) equals 48. So, she spends 48 minutes walking between the two houses.
