Answer:
75-25= 50. June earnings were 50 times greater than April.
Answer:
Step-by-step explanation:
A. (b - 10)(b + 10) = 180
-100 = 180
= 280
b = 
b = 2
Your A is correct.
B. 2 - 10 = c
c = 6.733200531 = 6.73 Try rounding to 3 significant figures.
C. 2 + 10 = d
d = 26.73320053 = 26.7
You are correct in all 3 answers. Perhaps you should try rounding to 3 significant figures for your c and d values.
I hope this helps!! ^-^
Answer:
13 units
Step-by-step explanation:
absolute value helps but
itd just be 7-(-6) = 13
Solve it using elimination method:
5x+3y=-10
3x+5y=-6
Essentially what you would want to do is eliminate a variable so you have to multiply the two equations so that the two “y”s cancel each other out. You do this by multiplying one by a negative number and the other one a positive number. Doesn’t matter what number you multiply the number with; however, both numbers need to be the same distance away from zero. Also, if you’re going to multiply one term, then all the terms will need to be multiplied.
-5(5x+3y)=-10
3(3x+5y)=-6
Distribute and Multiply:
-25x-15y=50
9x+15y=-18
Now add the two equations by adding the x’s together, y’s, and the total.
The y’s end up canceling each other.
-16x=32
Divide:
X=-2
Now that you have “X” substitute x from one of the equations from the beginning. You may do two for checking answers.
3(-2)+5y=-6
-6+5y=-6
5y=0
Y=0
The answer is:
x=-2
y=0
(-2,0)
