Answer:
20
Step-by-step explanation:
x=4
y=32
y=8x
y=160
y/8=x
160/8=20
x=20
Answer:
100x
Step-by-step explanation:
140 x 100 = 14,000
D=t/3
12=t/3
×3 ×3
___________
36=t
So the answer is D.) 36 kilometers
To simplify and solve this equation we must follow PEMDAS.
P=Parentheses
E=Exponents
M=Multiplication (from left to right)
D=Division (from left to right)
A=Addition
S=Substraction
We begin the process.
10^3=1000
10^7=10000000
New equation looks like this:
7.2*1000/1.8*10000000
We then multiply
7.2*1000= 7200
7200/1.8=4000
4000*10000000= 40000000000
<em>So our final answer is 40000000000.</em>
Hope this helps!
P.S. I forgot this was scientific notation and I solved it a different way. But both ways give the same answer. Let me know if you want the other method.
