Answer:
9 11/12
Step-by-step explanation:
4(x)=12
x=3
3 1/4=3 3/12
3(x)=12
x=4
6 2/3=6 8/12
3 3/12+6 8/12=9 11/12
Answer:
-10x
Step-by-step explanation:
multiply -5 with 2x
-5×2x= -10x
F(g) = 4g+6
1. when g = 2, output f(2) = 14
answer: 14
2. output = 18
18 = 4g+6
4g = 12
g = 3
answer: 3
3.when g = 4
f(4) = 16+6=22
answer
(4,22)
4. when input = 6 means g=6
f(6) = 24+6 = 30
different = 30-6 = 24
answer: 24
Answer:
x = 465 km
y = 735 km
Step-by-step explanation:
Step 1: Write out equations
x + y = 1200
y = x + 270
Step 2: Find <em>x</em> using substitution
x + (x + 270) = 1200
2x + 270 = 1200
2x = 930
x = 465
Step 3: Plug in <em>x </em>to find<em> y</em>
y = 465 + 270
y = 735
