4.5 = 2a
Solving
4.5 = 2a
Solving for variable 'a'.
</span>
<span>Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
4.5 + -2a = 2a + -2a
</span>
<span>Combine like terms: 2a + -2a = 0
4.5 + -2a = 0
</span>
<span>Add '-4.5' to each side of the equation.
4.5 + -4.5 + -2a = 0 + -4.5
</span>
<span>Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -2a = 0 + -4.5
-2a = 0 + -4.5
</span>
<span>Combine like terms: 0 + -4.5 = -4.5
-2a = -4.5
Divide each side by '-2'.
a = 2.25
Simplifying
a = 2.25
Let's check: 2 x 2.25 = 4.5
Next time, follow these steps and you will pass

Answer:
z= 5/14
Step-by-step explanation:
Let's solve your equation step-by-step.
5−2(3z+2)=−4(1−2z)
Step 1: Simplify both sides of the equation.
5−2(3z+2)=−4(1−2z)
5+(−2)(3z)+(−2)(2)=(−4)(1)+(−4)(−2z)(Distribute)
5+−6z+−4=−4+8z
(−6z)+(5+−4)=8z−4(Combine Like Terms)
−6z+1=8z−4
−6z+1=8z−4
Step 2: Subtract 8z from both sides.
−6z+1−8z=8z−4−8z
−14z+1=−4
Step 3: Subtract 1 from both sides.
−14z+1−1=−4−1
−14z=−5
Step 4: Divide both sides by -14.
−14z/ = -5
−14 -14
=5/14
z= 5/14
the answer is negative sixteen or -16
Answer:
The answer is 24
Step-by-step explanation:
If the restaurant fee is $7.5 and the price is $14 per pizza, she has $52.5 to spend on the pizzas after we deduct the restaurant fee.
That means she can get 52.5 / 14 = 3.75 pizzas.
- Since she can't get .75 pizza, we can assume that she will order 3, which in total makes 8 x 3 = 24 slices.
- If she can however order 3.75 pizzas, .75 x 8 makes 6 slices so it is a total of 30 slices for 3.75 pizzas.
I hope this answer helps.
Answer:
7.5 miles per hour
Step-by-step explanation:
Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate
To find: speed in miles per hour
Solution:
Distance travelled by Kayla = 
mile
Time = 
hour
To find the speed in miles per hour, use the following formula:
Speed = Distance ÷ Time = 
miles per hour
