Answer:
First question is 4,000
Second question is 2000
Step-by-step explanation:
You look at the point at which the graph lines meet and that is how you find you constant of proportionally.
I think the answer is 0.8 or 0.78.
You divide 140/180 which gives you 0.77777778
You can either round up to the nearest hundredth or tenth.
A=lb
a=100×40=4000cm^2
a=0.5×lb
a=0.5×40×30
a=600cm^2
a=4000+600
a=4600cm^2 hope it helps!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
The answer is C
Step-by-step explanation:
Let's solve your equation step-by-step.
Question 1: −2(6−2x) =4(−3+x)
Step 1: Simplify both sides of the equation.
−2(6−2x) =4(−3+x)
(−2) (6) +(−2) (−2x) =(4)(−3)+(4)(x)(Distribute)
−12+4x=−12+4x
4x−12=4x−12
Step 2: Subtract 4x from both sides.
4x−12−4x=4x−12−4x
−12=−12
Step 3: Add 12 to both sides.
−12+12=−12+12
0=0
Answer: All real numbers are solutions.
Question 2:
Let's
solve your equation step-by-step.
5−1(2x+3)
=−2(4+x)
Step 1:
Simplify both sides of the equation.
5−1(2x+3)
=−2(4+x)
5+(−1)
(2x) +(−1) (3) =(−2) (4)+(−2)(x)(Distribute)
5+−2x+−3=−8+−2x
(−2x)
+(5+−3) =−2x−8(Combine Like Terms)
−2x+2=−2x−8
−2x+2=−2x−8
Step 2:
Add 2x to both sides.
−2x+2+2x=−2x−8+2x
2=−8
Step 3:
Subtract 2 from both sides.
2−2=−8−2
0=−10
Answer: There are no solutions.
