Answer:
b= -8
Step-by-step explanation:
we have: 3y +12 = 6x <=> y + 4 = 2x <=> y= 2x - 4
=> 2y=4x + b
<=> 2(2x-4) = 4x +b
<=> 4x - 8= 4x +b
<=> b = -8
Answer:
Evaluate each expression for a = 4, b = 2, and c = 5.
c − a
Take $1.75 from the $10 then dived the 55cents into the sum. Thus $10 - $1.75 = $8.25. / .55 =15 miles exactly
R = 3(t+4) + 1

5 × 70 = 5 × 7 tens = 350
WHY?
1 ten = 10 ones
70 ÷ 10 = 7
So 7 tens.
