As go up the number sequence it is just the number added to get the new number plus 1. For example, since 2+3=5, 5+3=8+1=9
Answer:
7. 37
8. 74
9. 402
10. 74
Step-by-step explanation:
You can simplify the expressions and then do the substitution of the variable value, or you can simply plug in the numbers and do the arithmetic. Either way takes about the same effort.
7. 3(5·4 -1) -4(3·4 -7) = 3·19 -4·5 = 57 -20 = 37
8. 3(5·4 -6) +4(20 -3·4) = 3·14 +4·8 = 74
9. 5(10r +3) -7r = 50r +15 -7r = 43r +15 = 43·9 +15 = 402
10. 4(5r -3) -2(6r -7) = 20r -12 -12r +14 = 8r +2 = 8·9 +2 = 74
Hello!
Answer:
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
<em>First, you switch sides. *Group like terms*</em>
<em>Then, you add the similar to elements. You can also add the numbers from left to right.</em>
, is the correct answer.
Hope this helps!
Have a nice day! :)
Y - y1 = m(x - x1)
y - 6 = (1/2)(x - (-3))
y - 6 = (1/2)(x + 3)
Yoooo the answer is A, -19. hope this helps, have an amazing day :)
