Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
Answer:
7. 5
pizza
8. B
9. 11
inches
10. -12
11. 
12. 4
Step-by-step explanation:
7. 3
+ 2 
make them mixed fractions:
+ 
get a common denominator by multiplying
by 4:
+ 
add the numerators: 
simplify the fraction by dividing 45 by 8: 5 
8. 3 x 6 = 18
5 x 6 = 30
7 x 6 = 42
9 x 6 = 54
therefore, y = 6x
9. 5:7 is similar to 8:L
divide 8 by 5: 1 
multiply 7 by 1
: 11 
L = 11
inches
10. 5 - 2x = 29
subtract 5 from each side: -2x = 24
divide each side by -2: x = -12
11. fruit = 15%
15% = 15/100
simplify by dividing by 5: 
12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
Answer:
124°
Step-by-step explanation:
cos X = (11²+7²-16²)/2(11)(7)
= (121+49-256)/154
= -86/154
= -0.5584
X = cos~¹ -0.5584 = 124°
Combine the like terms:
3 - 12t + 8t = 3 - 4t
simplified answer is
-4t + 3
