Answer:
Z=0.8
Step-by-step explanation:
Step-by-step explanation:
Combine the opposite terms
2z+2+4z=7
Add
2z and 4z
6z+2=7
Move all terms not containing z to the right side of the equation.
Subtract 2 from both sides of the equation.
6z=7−2
6z=5
Divide each term:
6z/6 = 5/6
Decimal Form:
z=0.8
Answer:
yes
Step-by-step explanation:
8 × 90 = 720
4 × 180 (half of 8, double of 90) = 720
2 × 360 (half of 4, double of 180) = 720
1 × 720 = 720
Answer:
20
Step-by-step explanation:
Plugin x = 10 and y = 5 in the expression.
x + 2y = 10 + 2*5
= 10 + 10
= 20
1 hour = 3600 seconds
3 × 3600 = 10800
<em>10800 yards per hour
</em>
1 mile = 1760 yards
<em>
</em>10800 ÷ 1760 = 6.13
6.13 miles per hour
Answer: 1 unit = 557 miles
Step-by-step explanation: the scale factor is the same as a ratio, so therefore it should just be your distance key on the map
