Answer:
Step-by-step explanation:
1)
y = 5x-4 when x=5
y = 5*5-4
y = 25-4
y = 21
y = -2/5x + 3/8 when x = 1/3
y = -2/5 * 1/3 + 3/8
y = -2/15 + 3/8
y = -6/120
y = -1/20
y = 3x + 12 when x = 4
y = 3*4 + 12
y = 12 + 12
y = 24
To convert larger units to smaller units mulitply when the units are smaller you need more pf them to express the same measure. To convert smaller units to larger units, divide. When the units are larger, you need fewer of them to express the same measure.
Answer:
I can't draw number 1 and 2, but
1. 6 stacked cubes
2. 10 stacked cubes
3. f=6, e=10, v=6
4. f=5, e=12, v=8
5. f=6, e=12, v=8
1.4 repeating?
3x+3=5x-10+7x
3x+3=12x-10
3=9x-10
13=9x
1.4 repeating=x
