Measure of x is 74 degrees
Answer:
17. 13 miles : 1 hour
19. 12 saved : 1 week
21. $0.47 : 1 pound
23. $1.33 : 1 gallon
Step-by-step explanation:
Your goal is to make the second numbers, "1." So divide the first numbers by the second number to simplify.
Ex: 104 ÷ 8 = 13 Therefore, 13 miles per 1 hour (13 miles : 1 hour)
Answer:
1/4 - 3 2/5 - (2 1/3 - 1/4) =
-157/30=
-5 7/30
≅ -5.2333333
Step-by-step explanation:
Answer:
-
Step-by-step explanation:
-x= -1x. (The 1 is invisible)
Now lets do the 3*-1= -3
You still have both of the x's.
All you do is add them. 1+1=2
So, your exponent is going to be 2 with x attached
***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x (
) now since you have 2 (
) which equals (
)
Looks Like:
3x* -x
=3x* -(1)x
= 
Hope this helped :)
Answer:
The first equation answer is 10
And the second one 6
Step-by-step explanation:
The first equation
2/5 x +3= 2/3x +1/3
2x + 15/5 = 6x+3/9 the cress cross
9(2x + 15) = 5(6x + 3)
18x + 135 = 30x +15
135-15 = 30x - 18x
120 = 12x
120/12 =12x/12
10 = x
X =10
The second one
-2.6b +4 =0.9b - 17
-2.6b - 0.9b = - 17 - 4
-2.6b + (-0.9b) = - 17 + (-4)
-3.5b = - 21
-3.5b/-3.5 = - 21 /-3.5
B= 6
